would appear to exclude it from yorkiana, but which agree 

 with aus tralis, as, in fact, does the whole of his description. 

 On the other hand, Schoch described the elytra as being trans- 

 versely scratched at the sides and posteriorly, and the anterior 

 tibiae of the male as bidentate, characters which exclude it from 

 australis, but render it probable that the specimen he 

 described really belongs to yorkiana. 



There is, of course, the possibility that the type of 

 deyrollei really belongs to neither australis nor yorkiana; but 

 the quoted extracts render it quite evident that the specimens 

 described as deyrollei by Thomson and Schoch, belong to two 

 distinct species. 



Lomaptera australis, Wallace. 

 PI. xiii., figs. 161, 162. 



The description of this species, of which only the male 

 was known to Wallace, is rather short and somewhat unsatis- 

 factory. I have seen the name attached to several green 

 species, but am fairly confident that five males (from Cape 

 York, Coen River, Cairns, and Darnley Island) and a female 

 (from the Coen River) belong to the species. (23 ) These speci- 

 mens are much the same in size and colour as yorkiana, but 

 differ in having the pygidium subcorneal, instead of trans- 

 versely keeled, and the elytra with transverse scratches over 

 most of their surface only, agreeing well with "elytra finely 

 transversely striate, the base smooth." They range in length 

 from 11J-13J lines (the types were 13-15 lines). The front 

 tibiae were described as "inermibus," and, again, as having 

 the "outer edge quite smooth." But probably the apical 

 tooth was regarded as a spur. 



The female differs from the male in having the elytra 

 less narrowed posteriorly, the pygidium compressed on each 

 side (so that it appears almost keeled longitudinally), abdomen 

 strongly convex along middle, and front tibiae obtusely 

 dentate near apex. 



The species appears to be the same as the one subsequently 

 named prasina, from Aru, and still later as irnitatrix, from 

 Darnley Island; the latter has already been noted as a 

 synonym of the former. 



Lomaptera hackeri, Lea.

 In a long series of this species recently taken at the 

 Coen River by Mr. W. D. Dodd, about one-fourth of the 



<23) Mr. W. D. Dodd has recently taken it in abundance at the 

 Coen River.
