354 Mr. F. P. Pascoe on new Genera • 



Exeniotis coUaris. PI. XIV. fig. 7. 



E. angusta, fusca, indumento pallidiore dense tecta ; capite supra 

 late depresso ; antennis prothorace sesquilongioribus ; prothorace 

 pone apicem fere cylindrico, apice ipso utrinque fortiter lobato, 

 supra angulato, depresso, tuberculis setigeris paucls munito ; ely- 

 tris latitudiue triplo longioribus, singulis tuberculis conicis seti- 

 geris in series tres instructis ; corpore infra (sine indumento) 

 piceo-testaceo, granulis distinctis notato ; pedibus tenuiter setn- 

 losis. Long. 2\ lin. 



Uab. Amazons (St. Paulo). 



Anxtlopoma. 



(Ancylopominae.) 



Caput rotundatum, parum cxsertum; dypeus distinctus, postice 

 arcuatus. Oculi magni, prominuli, reniformes, grosse granulati. 

 Palpi maxillares elongati, articulo ultimo securiformi. Antennce 

 valida), quam corpus dimidio longiores, pilosulai, 11-articulata?, art. 

 basali brevi, secundo dimidio breviore, caeteris ad decimum ob- 

 conicis, subajqualibus, quatuor idtimis sensim crassioribus, ultimo 

 ipso ovato. Prothorax subobconicus, apice truncatus, angulis 

 antieis utrinque in spinam recurvam productus. Eb/ira oblonga, 

 paulo depressa, prothorace basi duplo latiora ; epipleura Integra. 

 Femora sublinearia ; tibice rectae, hand calcaratae ; tarsi graciles, 4 

 postici longiusculi. Prosternum subangustum, inter coxas cleva- 

 tum, postice declive. Mesostemum depressum. Processus inter- 

 coxaHs angustus, antice rotundatus. 



The structure of the mouth and of the intermediate cotyloid 

 cavities technically approximates this genus to such gi'oups as 

 the Zophcrinai, Stenosinje, &c. ; but it "wants the essential 

 characters which would authorize its association with either of 

 them. As I have only one specimen, I have not ventured to 

 examine the tropin, except in situ ; but the mentum appears to 

 be cordiform, leaving part of the maxilla? exposed on each side, 

 and the labium small and somewhat masked by its palpi, 

 which are inserted, apparently, at its base. The sculptiu-e of 

 the elytra, and the slender elongate intermediate and posterior 

 tarsi, especially the latter, are not found in any members of 

 the subfamilies to which the genus is here approximated, 

 while the form of the prothorax is quite unique. I think 

 there can be no doubt that, according to Lacordaire's system, 

 it represents a new subfamily. Like the species of the two 

 preceding genera it is one of Mr. Bates's discoveries.
