INSECTA — HEMIPTERA.

Qrayii, and Hardwichii, from Nepal. The sub-genus Derepteryx has 
the abdomen laterally dilated outside the hemelytra ; the sides of pro- 
thorax much dilated and projecting anteriorly before the head. 
The reporter (Arch. 1842, i. p. 278) has characterized a new species 
from Van Diemen’s Land, Hypselopus incarnatus. 
LYGiEiTES . — Lygceus mutilatus, Pachymerus lacertosus, torquatus, 
and nigrocBneus, of the reporter, are new species from Van Diemen’s 
Land (ibid. p. 279), 
Capsine^. — Phytocoris varicornis of the reporter is also from Van 
Diemen’s Land (ibid. p. 280). Adam White (Trans. Ent, Soc, Lond, iii. 
p. 93) has described Calliprepes Grayii, from Nepal, a new form of 
this family, which appears very aberrant ; and Eucerocoris Westwoodii, 
from Sierra Leone, from whence also E. nigriceps, Westw., has its 
origin, and whose locality has hitherto been unknown. 
Aradiedje. — A new species, from Van Diemen’s Land has been 
described by the reporter, Aradus a%istralis (Arch. 1842, i. p. 281). 
Reduvini. — ^T he reporter (ibid.) has enriched this family with two new 
genera ; Isodermus, with an extremely flat body, no ocelli, and with lobes, 
for holding, between the claws, with one new species, I. planus ; and 
Dicrotelus, resembling Pygolampis and Stenopoda, but diflfering, by 
dentated claws, &c., with one apterous species, D. prolixus ; besides 
four new species. Nobis geniculata, Pirates fuliginosus, Arilus aus- 
tralis, Emesa juncea, all from Van Diemen’s Land. 
Galgulid^. — Mononyx suberosus of the reporter is from the same 
place (ibid. 285). 
Fulgoreid.e. — Guerin (Deless. Souv. ii. p. 66, t. 16), has given 
splendid plates of Ftilgora Delessertii and subocellata (see Report for 
1839, p. 321). F. rajah, formerly characterized, is here shown to be 
identical with F. pyrorhynch%is, Don. 
Westwood (Ann. Nat. Hist. ix. p. 118) has published several new 
species, with short but clear descriptions : Fulgora (Pyrops) Spinolce, 
allied to the F. Candelaria, from Mysore and Assam ; guttulata, from 
Northern India ; virescens, from India ; F. (Episcius, Spin. ?) amabilis, 
from Mexico ; Eurybrachis insignis, from Malabar. 
The same author (Linnaean Transact, xix. p. 1) has published a very 
valuable paper upon the genus Derbe, F., of which previously only a very 
slight sketch was given (see Report for 1840, p. 242), and to which he 
has now appended several additions. The generic name, Derbe, is confined 
to those South American species which are of a stout form, have longer 
legs, a proboscis reaching to the middle of the abdomen, shorter antennae, 
and longer naked wings ; with them he places D. hoemorrhaidalis, F. ; ^ 
* The D. hcemorrhoidalis, of the Berlin collection, differs from the generic 
type of W estwood, in the wing-veins, &c,
