ME, F. P. PASC0E ON THE CTTRCULIONID^. 



Cryptaspis. 

 (Cholina?.) 



Caput rotundatum ; rostrum elongatum, arcuatum, cylindricum, 

 apice depressum ; scrobes pra?mediana?, oculos attingentes. An- 

 tenna graciles ; funiculus articulo primo longiore, ca3teris ob- 

 longis ; clava elliptiea, subadnata. Oculi rotundati. JProthorax 

 arnpliatus, lobis ocularibus prominulis. Scutellum nullum. 

 Elytra subtrigonata, prothorace angustiora. Pedes elongati ; 

 femora vix incrassata, antica longiora, infra leviter dentata ; 

 tibicd fere recta?, compressa?, apice inermes, quatuor posteriores 

 apicein versus extus eiliata? ; tarsi lati ; unguiculi liberi, ap- 

 proximate JBropectus ampliatum, integrum. Metasternum 

 breve. Abdomen segmento basali amplo, secundo multo breviore. 



The shortness of the metasternum approximates this genus to 

 Sclerosomus, which is the only other one of the subfamily having the 

 same character. Prom that, however, it differs in many respects 

 — notably in the tibia? not being bimucronate, in the large and 

 non-emarginate propectus, and in the absence of a scutellum. I 

 have adopted M. Jekel's catalogue name, under which the species 

 described below has long been known in collections. 



Cryptaspis amplicollis. (PI. XI. fig. 10.) C. obovata, nigra, 

 squamositate grisea supra tecta ; capite vage squamoso ; rostro basi 

 leviter pimctuiato ; antennis ferrugineis ; funiculi articulo primo se- 

 cundo duplo longiore, 2.-4. obconicis, 5.-7. oblongo-obovatis ; clava 

 articulo basali reliquis conjunctim aequalibus ; prothorace transverso, 

 subtiliter granulato ; elytris prothorace plus sesquilongioribus, obso- 

 lete granulatis ; corpore infra vage squamoso; pedibus squamis pili- 

 formibus parce vestitis. Long. 4 lin.

Guioperus eques. G. ovatus, niger, umbrino-squamosus, elytris

 postice sitis ; corpore infra pedibusque sordide umbrino-squamosis. 

 Long. 8 lin.

The metasternum presents a fold or crest behind each of the 

 posterior coxa? in the species of this genus ; but in this it is so 

 raised as to form a stout spine or tooth. This is a very distinct
