and lutescens resemble it in this respect, but have their punctura" 

 tion throughout (including that of the scutellum) very much 

 finer still. In the present species the punctures of the scutellum 

 are scarcely so fine as in the European B.gravidus and very much 

 less close. This is the insect that in a former paper (Tr. R.S., 

 S.A., 1892, p. 28) I called a var. of JV. nitidiusculus. I now find 

 that besides the notable colour differences its head is less even, 

 and less closely punctulate, and that its general puncturation is 

 less strongly impressed. 



W. Australia ; taken by Mr. Meyrick. 



The species of Notohrachypterus are now sufficiently numerous 

 to call for a tabular statement of their distinctive characters, as 

 follows : — 



A. Pronotum very distinctly (in no instance very 

 finely) punctulate. 

 B. Hindmargin of propygidium strongly and 



angularly produced in the middle ... cvebev, Blackb. 



BB. Hindmargin of propygidium at most sinuate. 

 C. Upper surface black (puncturation of head 



a little closer than in australis) ... nitidiusculus, Blackb. 



CO. Upper surface brown or testaceous. 



D. Puncturation of head fine and close 

 (about as in the European Brachypterus 

 gravidu>i, Illig. but more asperate ... australis, BlacJch. 

 DD. Puncturation of head very much closer, 



quite confluent .. ... ... lutescens, Blackb. 



DDD. Puncturation of head very distinctly 

 less close than in australis. 

 E. Pronotum closely punctulate through- 

 out, continuously with scutellum. 

 F. Colour of body dark brown above 

 and beneath ; elytra more coarsely 

 and closely punctulate ... ... crassiusculus, j8/acA'&. 



FF. Colour of body testaceous or rufo- 

 testaceous above and beneath ; 

 elytra less coarsely and closely 

 punctulate ... ... ... bifoveatus, Bla"Jcb. 



EE. Pronotum about base and front of (? testaceus, ^o^em.) 

 scutellum quite sparsely punctu- 

 late; scutellum Levigate behind ... pauxillus, Blackb. 

 AA. Pronotum very finely (scarcely distinctly) 



punctulate ... ... ... ... lilliputanus, Blackb.

This genus contains a good many species that probably appear 

 under two names in Masters' Catalogue. B. Haagi, Reitter, 

 must, as I have already pointed out (Tr. R.S., S.A., 1894, p. 203) 

 almost certainly be regarded as a synonym of Murrayi, Macl. 

 I have no doubt that B. blandus, Murr., is a mere variety 

 (scarcely deserving to be called even that) of B. hinotatus, Murr. 

 It is really difficult to determine from the descriptions what the 

 author regarded as the difference between the two species. I
