42 Mr. F. P. Pascoe on new Genera and Species of 



Blepegenes aruspex. PI. X. fig. 2. 



B. cupreo-fuscus vel -niger, subopacus ; elytris costis quatuor nitidis. 



Hah. Kiama. 



Dark copper-brown or bronze, sometimes bronze-black, nearly 

 opaque ; head and protliorax impunctate, the latter with four 

 foveas on the disk, or the lateral foveas are connected and form 

 an irregular longitudinal impression, each side before the mid- 

 dle expanding into a strong triangular spine, subhorizontal or 

 directed a little upwards ; near the base a much smaller spine 

 or tooth, the posterior part of which slopes directly inwards to 

 the base ; scutellum transversely triangular ; elytra more than 

 three times the length of the prothorax, each with four glossy 

 costas, none of them reaching to the apex, the sutural and 

 second costa having a less elevated opaque costa between them, 

 each apex ending in a short diverging mucro ; legs ferruginous 

 brown, shining ; body beneath very glossy, brown ; antennas 

 ferruginous. Length 8-9 lines. 



Byallius. 



Subfamily Adeliinm. 



Antenna art. tertio elongato, cylindrico. 



From parum convexa, sulci longitudinales nulli. 



Maxlike lobo interiore unciformi. 



Elytra obovata, reticulata, plica epipleurali obsoleta. 



, Head deeply inserted into the prothorax, the front slightly 

 convex, without any grooves ; the clypeus broadly truncate 

 at the apex, separated from the front by a narrow, distinct, 

 arched line. Eyes transverse, impinged on by the antennary 

 ridges. Antennas filiform ; scape obconic, the third joint cy- 

 lindrical, longer than the fourth and fifth together ; the two 

 latter and remainder to the tenth obconic, becoming very gra- 

 dually shorter ; the eleventh longer, ovate, depressed. Mentum 

 rather narrow behind, rounded at the sides anteriorly ; lower 

 lip transverse, slightly emarginate and fringed at the apex, 

 largely excavated in the middle on each side for the insertion 

 of the labial palpi. Maxillas with the inner lobe narrow, 

 curved, and gradually terminating in a very distinct point ; 

 their palpi stout, the basal joint very short, the terminal securi- 

 form. Prothorax depressed, slightly foliaceous and rounded at 

 the sides, the apex strongly emarginate and much narrower 

 than the base, the latter broadly lobed. Elytra obovate, reti- 

 culate, the epipleural fold obsolete. Legs moderately long ; 

 femora nearly linear, compressed ; posterior tarsi compressed, 

 the basal joint nearly as long as the rest together, the penulti-
