FULGORA (HOTINA) CLAVATA. WESTW.
Fulgoi-a rostro corporis dimidii longitudine, piceo, apice in globmn subrotunduin testaceum dilatato ; liemelytris
basi subalbidis, fusco-raaeulatis, apice fasco albido-ocellatis et maculatis; alis subpiu-pureo-albidis apice late
ftisco ; oorporc albo-farinoso.
Fulgora with the rostiiim about half the length of the body, of a pitchy colour, the apex dilated into a shining
testaceous globe, the hemelytra very farinose, with the base of a pale buff colour with pitchy brown spots, and the
extremity brown with white rings and dots ; the under wings pale dull purple, (which fades into pale buff) with a
broad brown apex, the body very thickly clothed with white powder.
Length of the body (with the rostrum) l i inch. Expansion of the hemelytra 3-3| inches.
Inhabits Assam. In the coUectious of the British Museum, Hope, Cantor, Westwood.
SYN,—Fidgora clavata, Westw. in Linn. Trans, xviii, p. 139 ; pi. 12 ; fig. 1.
DESCRIPTION.—MY original figure and description of this species lia\ing been made from a small faded
specimen^ I here present the reader with a figure of the species in its fresli state, in which it is very densely
covered with the white powder which is secreted by many other Homopterous insects. The rostrum
is dotted with this farinose secretion, the upper side of the thorax is fulvous, and the upper
surface of the abdominal segments (where uncovered by the white powder) is bright red; the legs are
black, except the posterior femora, which are pale fulvous. I am indebted to the Rev. F. W. Hope for
the specimen figured.
OBSERVATIONS.—Much interest has attached to the insects of this ciu'ious genus ever since the
period when the celebrated Madame Merian published her statement that the large American species
(Fulgora laternaria) possesses the power of emitting a strong light from the dilated anterior part of the
head. No subsequent traveller or author of credit appears to have observed the least traces of luminosity
in this species, although it is far from rare in some parts of South America. Messrs. Lacordaire,
Richard and Hancock, all of whom had opportunities of examining the living insect, failed in
detecting any emission of light, and their statements have been confirmed to me both by the late
lamented Prince Maximilian of Nieuwied, and J. fliers, Esq., whose long residence in Brazil and
fondness for entomological pursuits afforded to both abundant means of observation. As regards the
oriental species (although one of them was represented by Donovan as emitting a strong radiating light
fi'om its rostrum,) I cannot find a single authority for their luminosity'; and Dr. Cantor, who was
engaged in the late Chinese expedition (and by whom the first specimens of the species here figured
were transmitted to Europe,) has informed Mr. Hope that he never observed the slightest luminosity
in the common Chinese E. Candelaria. Whether the species may not at certain periods of the year
become, or whether either of the sexes may not be, luminous, is still, however, a question for inquiry,
especially as its existence has lately been re-asscrted.

FULGORA (IIOTINA) GEMMATA, WESTW.
Fulgora capite thoraceque fulvis nigi-o-maculatis ; abdomine nigro, segmentorum apicibus viridibus ; hemelytris
b.asi viridibus, apice obscure brunneo rufis ; nigro-punctatis et am-antio-guttatis ; alis posticis viridibus apice late
maculisiiue oblongis nigris.
Fulgora with the head and thorax fulvous with black markings ; the abdomen black with the extremity of the
segments narrowly green ; the hemelytra are green at the base which gradually changes into a dark brownish
crimson, they are entirely covered with minute black dots, each bemg ornamented with about 30 bright orange spots ;
the hind wings are gi-een, with a broad black border, which extends into the disk of the wing, forming several
large black blotches ; the legs are dark red.
Length of the body (exclusive of the rostrum) ^ inch. Expansion of the hemelytra 2 i inches.
Inhabits the Himalayan range. In my own Collection.
