274 Mr. F. Bates' Descriptions of 



punctured ; flanks of the prothorax tuberculate ; eplpleural 

 fold strongly and coarsely punctured and transversely 

 rugose ; prosternal process curved round the coxfe behind ; 

 anterior tibia3 unidentate as in Diiboulayi, but the outer 

 edge, from the base to the tooth, is rather strongly crenu- 

 late ; the four hind tibite a little arched, decidedly com- 

 pressed, hispid and (the intermediate the most strongly) 

 asperous, with the outer edges finely denticulate : the 

 pilose fringing to the tarsi much larger than in Duhoulayi, 

 and almost villose. 



Hah. — Champion Bay, W. Australia. One $ example 

 captured by Mr. Duboulay. 



By its differently formed prothorax and elytra, the pro- 

 sternal process curved round the coxa3 behind, the crenu- 

 lated outer margin of the anterior tibite, and the bowed 

 four posterior tibiae, Avith their outer margins denticulate, 

 this species might almost fittingly be erected into a distinct 

 genus. 



Nyctozoilus reticiilatus, n. sp. 



Long. 1\ to ^\ lin. ; elytra lat. 4^ to 5\ lin. — Elongate- 

 oval, convex ; dull-black, squalid ; legs, &c. and underside 

 deep black ; head and prothorax finely and evenly punc- 

 tured ; the former depressed on the crown (between the 

 eyes), the antennary orljits obliquely rounded at the sides, 

 flattened above ; epistoma short, trapezoidal, separated fi-om 

 the front by a strongly impressed line, angular at the sides, 

 front angles rounded, a^jex broadly emarginate ; lahrum 

 strongly transverse, the membrane attaching it to the epi- 

 stoma distinctly visible, front angles strongly rounded, apex 

 deeply emarginate : prothorax transverse, wider at base 

 than at apex, sides moderately rounded, the edges thickened, 

 the margins expanded and concave ; apex arcuately emar- 

 ginate, the emargination sometimes a little angular at the 

 sides ; base bisinuate, closely applied to the elytra, all the 

 angles prominent, subacute, slightly outwardly directed, 

 the hind overlapping the humeral angles of the elytra; 

 with two (the u])per and innermost one largest and oval) 

 foveate depressions at each side the middle of the disc, 

 between these an oblong depression and another — trans- 

 verse, linear and sub-basal — extending along the whole 

 width of the disc ; the margins at the hind angles slightly 

 plicate : scutellum rather large, convex, transversely tri- 

 angular, faintly punctured ; elytra oblong-oval, convex.
