Helota, with the upper surface of the body brassy, the sides copper-coloured ; punctiu-ed and rugose ; and with
elevated elongated shining tubercles which form longitudinal strias on the elytra ; the latter also marked with four
raised fulvous ronud spots ; thighs fulvous, with the tips green ; tihice alternately fulvous and pitchy ; tarsi pitchy,
basal half of the terminal joint of the tarsi fulvous ; body beneath pale fulvous ; the head, except in the middle of

GEXEEIC CHARACTEK.—A new genus among the Necrophagous Coleoptera, most nearly allied to Pteroloma.
Head wide, narrowed in f r o n t ; labram transverse, with the anterior lateral angles rounded ; the middle emarginate ;
the fore margin membranaceous and cihated ; mandibles corneous, somewhat sickle-shaped, acute at the tip, cihated
on the inner margin, not toothed ; maxillES, with the outer lobe broad, short, and densely bearded, inner lobe
short, ciliated, unai-med ; maxillary palpi short, filiform, with the 2, 3, and 4 joints, of nearly equal size ; mentum
Eubquach-ate ; labium short, broad, emarginate, and densely ciliated ; palpi short, simple ; antenuEO elongate,
somewhat filiform, with the apical joints shghtly thickened ; prothorax broad, transverse, with the sides rounded
and elevated, and the posterior margin shghtly transversely produced over the base of the scutellum ; elytra
subquadrate, subconvex, rounded at the outer posterior angles ; legs long and slender ; tarsi setose, 5-jointed, the
4th joint subbilobed ; the anterior tarsi shorter and broader than the others.
Apatetica, nigra, nitida, lateribus prothoracis fulvis, elytris ceneis ; capite et pronoto punctatis, illo inter
antennas bi-impresso ; labro fulvo, mandibuhs fulvo-piceis ; antennis fulvis ; elytris pnnctato-sti-iatis ; femoribus
seneis basi piceis ; tibiis ta,rsique fulvis ; coi-pore subtns nigro nitido, marginibus inflexis elytrorum asneis nitidis.
Apatetica, black and shining, the sides of the prothorax fulvous, and the elyti'a brassy green, head and pronotum
punctm-ed, the former with two impressions between the antennce ; labi-um and antennEe fulvous, mandibles pitchyfulvous
; elytra punctate-striated ; thighs brassy-pitchy at the base ; tibia; and tarsi fulvous ; body beneath, black
and shining, with the inflexed margins of the elytra shining brassy green.
Length of the insect, 4 Hues. Inhabits the HimaLiyan region. In Mus. Westwood.
I am indebted to H. G. Harrington, Esq., for my unique specimen of this interesting insect.
Figure 9 a, represents the labrum; 9 b, the mandible; 9 c, the maxülaí'; 9 d, the labium, &c. ;
9 e, the antennse; 9 / , the fore tarsus ; 9 cj, one of the hind tarsi.
* Dr. Erichson has had the rar e tact to discover and demonstrate, in an article published in Wiegmann' s Archives, that the singular
genus Pteroloma (Ilolocnemis, ScliiUing), placed by all preceding authors amongst the Carabidaj next to Nebria, belongs to the
family Silphidfe, near to Catops and Agyrtes. The insect above described fully confirms this relation of Pteroloma. Elapliropus
Caraboides of Motchoulsky, Bull, Mosc. 1839, t. 5. fig. E. seems also to possess an affinity with these insects.
