XXIII. Descriptions of some Species of exotic Heteropterous 
Hemiptera. By J.O. Westwoop, F.LS. 
[Read 1 August, 1842.] 
I sec leave to submit to the notice of the members of the Ento- 
mological Society figures and descriptions of several Heteropterous 
insects, belonging to the family Reduvide. Two of these belong 
to well known groups, and as such I should have hesitated in 
drawing up their isolated descriptions, did not their large size and 
fine colours render them especially worthy of attention. They 
are, in fact, considerably larger than any species of the family yet 
described. The third species differs in its structural characters so 
materially from the other groups in the family, that I have not 
hesitated in adding another to the already numerous genera of 
Reduvude. 
Sp. 1. Ectrichodia imperialis, Westw. (PI. VII. fig. 2.) 
Purpurea; antennis et hemelytris nigris, abdominis lateribus 
fulvo-fasciatis. (Fig. 2a, lateral view of the head.) 
Long. corp. unc. 13. 
Inhabits Cape Palmas on the west coast of tropical Africa. 
Collected by the Rev. Mr. Savage, and sent to the Rev. F. W. 
Hope: also in the British Museum from Sierra Leone. 
Purpurea vel purpureo-nigra, parte postica pronoti aneo-tincta ; 
capite parvo, inter oculos impressionibus duabus longitudi- 
nalibus; antennis nigris 6-articulatis (radicula basali haud 
inclusa), articulo 2ndo 1mo duplo longiori setoso, 3tio 1mo 
parum longiori, tribus ultimis gracillimis et sensim longitu- 
dine decrescentibus. Pronotum transversé et longitudinaliter 
impressum. Scutellum tuberculis duobus apicalibus, discoque 
impresso. Hemelytra nigra, cyaneo parum tincta. Pedes 
concolores, tibiis ad apicem spongiola fulva instructis. Ab- 
domen subtus purpureum, maculis lateralibus conoideis fulvis. 
I have applied the name of imperialis to this species, not only 
on account of its large size, but from its rich purple colour, varied 
at the sides of the abdomen with golden yellow.
