Exeniotis collaris. PI. XIY. 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 paucis munito ; ely- 

 tris latitudine triplo longioribus, singulis tuberculis conicis seti- 

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

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

 losis. Long. 2| lin. 



Hah. Amazons (St. Paulo). 



Ancylopoma. 



(Ancylopominae.) 



Caput rotundatum, parum exsertum; clypeus distinctus, postice 

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

 Palpi maxillares elongati, articulo ultimo securiformi. AntenncB 

 validae, quam corpus dimidio longiores, pilosulae, ll-articulatse, art. 

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

 conicis, subsequalibus, quatuor idtimis sensim crassioribus, ultimo 

 ipso ovato, ProiJiorax subobconicus, apice truncatus, angulis 

 anticis utrinque in spinam recurvam productus. Elytra oblonga, 

 paulo depressa, prothorace basi duplo latiora; epipleura Integra. 

 Femora sublinearia ; tihice rectse, haud calcaratae ; tarsi graciles, 4 

 postici longiusculi. Prosternum subangustum, inter coxas eleva- 

 tum, postice declive. Mesosternum depressum. Processus inter- 

 coxalis angustus, antice rotundatus. 



The structure of the mouth and of the intermediate cotyloid 

 cavities technically approximates this genus to such groups as 

 the Zopherina3, Steuosinae, &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 trophi, except in situ • but the mentum appears to 

 be cordiform, leaving part of the maxillas exposed on each side, 

 and the labium small and somewhat masked by its palpi, 

 which are inserted, apparently, at its base. The sculpture 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.
