than 8, 10-11 very short and nearly round, 11 smaller than 10. 

 Prolhorax subsinuate at apex, subtruncate at base, sides well 

 rounded, greatest width slightly in front of middle, lightly sinu- 

 ate behind; anterior angles obtuse, posterior sharply rectangular, 

 surface rugose (apparently longitudinally strigose under thin 

 clofTiing of hair). Scule/lum oval. Elytra wider than prothorax 

 at base and thrice as long, covered with a number (about 16) of 

 closely placed striae each containing closely placed, large, square 

 punctures, not cancellate as in E. gracilior Blackb.; hairy cloth- 

 ing more obvious at sides and apex. Underside and epipleurse 

 closely and coarsely punctate, each puncture bearing a short 

 hair; legs thin, tibia? not enlarged nor spined at apex. Dimen- 

 sions : 13 x 5 mm. 



Hob.— Chillagoe, N. Queensland (National Mus., Melbourne). 



A specimen, sex uncertain, sent by Mr. Kershaw, shows near 

 affinity to Blackburn's two species, from which it is clearly 

 separated by larger size, bicolorous surface, coarser sculpture, 

 hairy clothing and antennae (the tenth joint sharply differentiated 

 from ninth in size and shape). 



N. B. I have identified specimens of E. angusta Blackb., from 

 Perth, W.A., and have seen other examples from widely distant 

 parts of that State. My specimens of E. gracilior Blackb., are 

 from Lillimur, Victoria, and correspond well with the description 

 except in their larger size (11 x 3A mm.). 



Mniokophhus, n.g. Bolitophaginarum. 



Convex, widely ovate or obovate; mandibles bifid, last joint of 

 maxillary palpi clavate, of labial palpi subulate, maxillre fringed 

 (at least in M. costatus), antenna? rather short (not extending to 

 base of prothorax), with joint 2 as long as, but much stouter 

 than, joint 3, the apical two forming a pronounced club; pro- 

 sternum not produced backward, sides of pronotum explanate, 

 serrated or toothed, body more or less nodulose and squamose, 

 tibiae unspined at apex, tarsi and tarsal claws short; intercoxal 

 spaces wide. 



Minute insects with a facies of Mychestes, remarkable for the 

 length of the second joint of antenna;.
