NOTES O'X THE GEXiUS LISSOTBS. 



regretted that Westwood's original intention (i) not to 

 describe the species until the male was known was not 

 adhered to. 



LISSOTES FURCICORNIS, Westw. (Figs, z^, 33-) 



Readily distinguished from all other species by the 

 peculiar mandibles and strong cephalic tubercles; the 

 latter, however, are much less conspicuous on small 

 specimens than on large ones. The length, including the 

 mandibles, varies from 12 to 20 mm. 



It appears to be confined to \'ictoria, and is the only 

 ex-Tasmanian species known to me. 



LISSOTES RUDIS, n. sp. (Figs. 34, y^,, 36, 37, 58.) 



^lale. Black; sides setose. 



Head wide; a strong projection behind each eye and 

 a less distinct one in front; front somewhat obliquely and 

 feebly flattened; with large round punctures, dense at the 

 base and sides, and becoming sparser and smaller else- 

 where, and almost absent from the middle of the front. 

 Labrum rather feebly pointed. Mandibles moderately 

 stout, about as long as head or somewhat longer, strongly 

 concave at inner base; with a strong projection near base, 

 upper surface with a strong projection at middle, lower 

 surface between this and apex with a bi or tri cuspidate 

 mass. Prothorax very little, or not at all, wider than 

 widest part of head, sides finely serrated and gently 

 rounded, towards base somewhat oblique but not 

 notched; apex widely rounded in middle, somewhat flat- 

 tened or feebly depressed along middle, on each side of 

 which the punctures are smaller and sparser than else- 

 where, where they are dense and rather coarse. Elytra 

 with shoulders slightly projecting laterally; densely and 

 coarsely punctate; striae and interstices very feebly de- 

 fined. Length, excluding mandibles, 12^/2 — 20 (female 12 

 —15) mm.
