Nypsius^ n. gen. 
Apical joint of the maxillary palpi moderately stout, triangular, 
its apical and outer sides about equal in length, each very much 
longer than the inner side ; mandibles bifid at the tip ; antennae 
moderately long, the joints thickening a little towards their apex 
(5-10 subcylindrical in N. foveatus^ ^ )> 3 and 5 subequal in length, 
4 slightly longer ; head rather small, short, a little exserted, obliquely 
narrowed behind the eyes, the latter moderately large, coarsely 
granulated, somewhat widely separated, transverse as viewed from 
above ; prothorax strongly transverse, convex, feebly bisinuate at 
the base, with deep basal foveas and a median groove terminating 
in a depression or fovea behind ; elytra from four and one -half 
to five times the length of the prothorax, and in the widest part 
twice its breadth, elongate-oboval, or subparallel ; legs elongate, the 
tibiae and tarsi slender, the penultimate joint of the tarsi very 
feebly lamellate beneath, the posterior femora shallowly sulcate 
beneath towards the apex, the claws pectinate ; body more or less 
elongate, sparsely pubescent, metallic or with metallic lustre, 
winged. 
The two Tasmanian species referred to this genus can- 
not satisfactorily be included in any of the genera of 
Cistelidse as at present defined; I am, therefore, com- 
pelled to use a new generic name for them. Both species 
have an oblique groove on each elytron below the base. 
The Australian representatives of this family are, as 
noted by Blackburn, very difficult to deal with, many of 
them apparently requiring new genera for their receptiou. 
Nypsiics seneoiiiceus, n. sp. 
Elongate, rather broad, subparallel, depressed, very shining, 
seneo-piceous, indeterminately reddish-brown towards the suture ; 
the oral organs and antennse fusco-ferruginous ; the legs ferru- 
ginous, the femora darker ; above very sparsely clothed with 
fine, long, erect fuscous hairs. Head sparsely, finely punctate, 
behind the epistoma deeply transversely depressed ; the eyes 
moderately large, transverse, feebly emarginate, separated by a 
space equalling the width of one of the eyes as seen from above ; 
the antennae rather slender, not half the length of the body, 
joints 4-11 slightly decreasing in length, widening a little towards 
their apex, 9-11 equal in length. Prothorax convex, strongly trans- 
verse ; the sides rounded in front, straight and slightly converging 
from the middle to the base ; the hind angles rectangular ; the 
surface very sparsely, finely punctate, with a median channel, which
