APPENDIX IV
ORTHOPTERA, HYMENOPTERA, AND
HEMIPTERA
A List o f the Orthoptera, Hymenoptera, and Hemiptera collected
by Miss Kingsley on the River Ogowe, with Descriptions o f
some new Genera and Species. By W. F. KlRBY, F.L.S.,
F.E.S., &c., Assistant in Zoological Department, British
Museum (Natural History).
The collection formed by Miss Kingsley, though small,1 contained
several species of considerable interest, in addition to the
novelties ; and hence I have thought it worth while to prepare
a complete list. Eight species in all are here described as
new, for two of which it has been necessary to establish new
genera. It is, however, to be regretted that in most cases only
single specimens were received, and several of them were
immature, or the number of new species might have been
larger.
Order ORTHOPTERA.
Family Blattidse.
Subfamily P anchlorin
TRICHOMERA, gen. nov.
Female.— Apterous: front of head rounded, projecting beyond
the prothorax ; face hardly oblique ; antennae thickened
at base and tapering to tips ; prothorax moderately arched,
the hinder angles rounded off, those of the meso- and metathorax
less rounded and more produced backwards ; tibiae
1 This collection is entirely from Lembarene (River Ogowd). I have
no lists of collection of insects from Calabar.— M. H. K.
ORTHOPTERA, HYMENOPTERA, AND HEMIPTERA' 719
strongly spined above, but femora with no spines, but only
clothed with fine hair ; abdomen very broad, supra-anal plate
triangularly emarginate at the extremity to nearly half its
length , cerci very broad, pointed at the end, and a little shorter
than the'supra-anal lamina.
The unarmed femora place this genus in the Panchlorinae,
but in shape it resembles the females of some of the Blattinae.
The male is probably winged.
Trichomera insignata, sp. n.
Long. corp. 20-21 millim., lat. 13 millim.
. Female.-—Blackish, with testaceous markings; face nearly
smooth, shining black below the vertex, the sides, mouth, and
a band within the eyes and antennae testaceous ; vertex testaceous
in front, with blackish streaks projecting into it from
behind.; head and thorax clothed with fine down ; prothorax
and sides of meso- and metathorax finely punctured, middle of
meso- and metathorax and abdomen rather coarsely granulated
; mesothorax testaceous, somewhat speckled with reddish
brown, the centre filled up with a large blackish blotch, with
two projecting angles on each side in front a.nd behind, the
two innermost of the hinder projections extending to the
hinder margin of the prothorax, and the second of the front
projections connected with a large oblong black patch bordering
part of the sides of the prothorax ; meso- and metathorax
bordered on the sides with reddish brown and with several
irregular testaceous markings ; on the abdomen these are continued
more, regularly, forming a central and nearly parallel
series, and two outer series, the first of which is nearly straight
and the second connected with the testaceous border below
the lateral angles of the segments ; supra-anal plate black, with
a broad testaceous band on each side; cerci black ; antennae
reddish, shading into brown ; pectus testaceous ; abdomen
brown beneath.
Two specimens obtained.
Family Mantidae.
•Subfamily M a n t i n m .
HlERODULA, Burm.
A single immature specimen of this genus, remarkable for
the very heavy black band on the front femora and tibiae and
for the black spines of the latter.
