 at the base, gradually rising behind, then very abruptly decli- 

 vous, the declivous part and a short oblique line behind the 

 shoulder greyish white, the two largest tubercles above the 

 declivity elongate and studded, as well as elsewhere, with

Cryptacrus scops. 



C. brevis, convexus, supra sqnamis griseis fusco-variis obsitus, setu- 

 lisque erectis adspersus ; elytris nodulosis, intequaliter puuctatis, 

 pone medium griseis. Long. 2 liu. 



Hab. Para. 



Short, convex, covered with greyish, varied with brownish 

 scales ; rostrum rather short, the basal half scaly ; antennae 

 ferruginous ; prothorax transverse, subtriangular, longitudinally 

 sulcate in the middle, and on each side with two tubercles, 

 the anterior pair at the apex, the posterior larger and approxi- 

 mate to them, scutellar lobe produced ; scutellum punctiform ; 

 elytra much broader than the prothorax, very convex, gene- 

 rally nodulose, the intervals punctured, from the shoulder 

 curving to the suture a greyish raised line, towards the apex 

 entirely pale grey; legs short; tibiae compressed. 



A short stout species with nodulose elytra. 



DiAPOKESIS, 



Caput rotundatum ; oculi laterales, grosse granulati ; rostrum arcua- 

 tum, basi robustum, apice latius ; aerobes breves. Scapus anten- 

 narum oculum vix attingens; funiculus elougatus, linearis'; 

 clava distincta. Prothorax basi bisinuatus, lobis ocularibus ciliatis, 

 Scutellian inconspicuum. Elytra prothoraee paulo latiora, hume- 

 ris rotundatis. Rima pectoralis ante coxas intermedias terminata, 

 apice aperta. Pedes modice elongati ; femora vix clavata, infra 

 deutata ; tibice rectae, apice uncinatse ; tarsi articulo basali sub- 

 elongato ; unguiculi liberi. Abdomen segmento secundo tertio 

 longiore. 



One of the numerous Cryptorhynclms-^oxTCi^^ which, without 

 any salient characters, seems isolated by its facies from all 

 others ; in mere outline it slightly resembles Mcemactes. 



Diaporesis distincta. 



D. anguste elliptica, picea, squamis fulvo-brunneis vestita ; elytris 

 maculis duabus conspicuis, apiceque albis. Long. 4 lin.
