The dark ferruginous red colour of this species seems to be 

 constant. It is near L. politzdus, Macl., but is a much wider 

 insect, and shortei- in comparison with its width, its prothorax 

 more narrowed in front, and less strongly punctured, its front 

 tibiie more sharply dentate externally, ic. Compared with 

 L. geminatus, Westw., apart from coloui', it is a little more elon- 

 gate, with the discal punctures of the protliorax differently 

 shaped (each jjunoture being a short, deep transverse scratch), 

 and the depressed lateral margins of that segment much narrower, 

 and with the elytral stria; much less distinctly geminate, and the 

 interstices evidently less flat. The colour, size, and geminate 

 striation of the elytra, in combination with the nitid glabrous 

 surface, will distinguish it from all its described congeners 

 except L. oblongug, Har., which seems from its descrij)tion and 

 name to be a much more elongate insect.

OCNODUS, Burm. 



The following two species may be, I think, referred to this 

 genus, which, however, does not seem to me very clearly charac- 

 terised by its author, who, I should judge, had seen only the 

 female. If I should be incorrect in this determination the 

 species in question would have to be regarded as forming a new 

 genus near Ocnodus. The principal discrepancy is in connection 

 with Burmeister's statement that the club of the antenn;e is 

 "small." In the male before me the lamella? of the club are 

 longer than the preceding five joints of the antenn;e together ; in 

 an example whicli I believe to be its female, they are scarcely 

 shorter than the preceding five joints ; in the other species (of 

 which I have not seen a male) the lamelhe forming the club of 

 the antenna? in the female are as long as the preceding four joints 

 together. In a third species which I have described under the 

 name 0. luguhris (Proc. Linn. Soc, N.S.W., 1891, III.), the 

 lamelhe of the female are as in the latter. The antennie of all 

 these insects, however, are extremely like those of Mmchidius in all 

 respects, and as Burmeister calls the club in Mcechidms, " small," 

 also, I presume, it is a mere question of what one means by 

 "small" 



The two species described below are extremely like each other, 

 so like that I should hesitate to separate them if it were not for 

 a complete difference in the relation inter se of the clypeus and
