simis erectis obtecta. Abdomen sutura prima angulata. Corpus 

 pilosum. 



This genus is proposed for Platyomus Boisduvalt, Boh., a 

 very remarkable hairy form, which, as a Platyomus, has long 

 been an opprobium to our classification. The characters 

 which separate it from that genus, however, are, when viewed 

 in relation to the heterogeneity of its species, somewhat feeble ; 

 the principal relate to the rostrum, which is only slightly 

 emarginate at the tip, and is deeply and broadly excavated as 

 far as the eyes, the boundaries of the hollow on each side 

 being raised into a prominent ridge or crest. One thing is 

 quite certain, that this species has only a very distant affinity 

 with any Platyomus. 



Cyphus effusus. 



C. ovatus, dense cretaceo-squamulosus, supra viridescenti-undu- 

 latus ; prothorace transverso ; elytris irregularibus, apicibus 

 rotundatis, haud productis. Long. 6^ lin. 



Hob. Macas. 



Ovate, covered with cretaceous scales, tinted above with 

 pale green arranged in waved crossed bands ; head, antennas, 

 and legs spotted with black setulose scales ; rostrum deeply 

 excavated between the antennas, an impressed line continued 

 to the head ; prothorax very short, the sides, except at the 

 apex, nearly parallel, a broad excavation along the base ; 

 scutellum triangular ; elytra uneven, owing to the irregularity 

 of the raised interstitial lines, the intervals with a double row 

 of impressed punctures, the apices rounded and not produced. 

 Body beneath with a pale greenish tinge. 



This and the following species differ from the rest of the 

 genus in having a very short prothorax, with the sides, except 

 just at the apex, parallel. 



Cyphus sigillatus. 



C. ovatus, dense cretaceo-squamulosus, pone medium elytrorurn 

 fascia maculata et maculis duabus posticis notatus ; prothorace 

 transverso ; elytris supra paulo depressis, apicibus rotundatis 

 haud productis. Long. G| lin. 



Hab. Para. 



Ovate, covered with cretaceous scales, having a very slight 

 tint of green or grey ; head, antennas, and legs spotted with 

 black setulose scales ; rostrum broadly excavated between the 

 antennas, an impressed line continued to the head ; prothorax 

 very short, nearly parallel at the sides, but a little contracted 

 anteriorly, a broad excavation along the base ; scutellum 

 triangular ; elytra rather short, depressed above, the interstices 

 scarcely raised, the punctures small, in not very regular lines,
