two lateral rows contain larger punctures). Sternum smooth, 

 abdomen striolate, apical segments smooth. In £ three basal 

 joints of fore-tarsi much wider than 4th joint. In £ fore tarsi 

 of normal size, body more convex. Dimensions: 19 x 9 mm.

A pair, showing clear sexual characters, given me by their 

 captor. The species is nearest P. dispar Macl. (iu the 1st Section 

 of that author), but differs from it in the following details : — 

 different sexual characters, less convex and more oval form, 

 falcate posterior angles to prothorax, and smooth undersurface. 

 i In P. dispar, if correctly identified by me in specimens from 

 Kookynie and Kalgoorlie, the prosternum is transversely rugose 

 and the raetasternum finely pustulose). P. dispar was described 

 as from Swan River, but it must be noted that, until recently, 

 the whole State was so denominated. With considerable ex- 

 perience in collecting, and with collectors in the Perth district, 

 1 have seen nothing like P. dispar from this neighbourhood.

Pterohelceus reichei Breme. — In my revision of this genus, I 

 failed to identify, though having specimens before me, the larger 

 Tasmanian species as Dr. Breme's insect. The figure given in 

 that author's monograph shows prominently sculptured elytra] 

 costae, which then seemed inconsistent with the Tasmanian 

 specimens in the collections of Mr. Lea, and the Australian and 

 Macleay Museums. In the last two cases, they were erroneously 

 labelled yudrini Br. Knowing the great difficulty in illustrating 

 this form of sculpture with accuracy, and allowing for some 

 exaggeration in this, 1 now concur with Mr. Champion in his 

 identification of this species, which appears to be common in 

 the northern parts of Tasmania. 



P. walkeri Breme ( = P. riverince Macl.). Having re-examined 

 the presumed types of P. riverince in the Macleay Museum, I am 

 convinced that it is, at most, but a slight variety of P. walkeri- 

 the differences noted being such as commonly occur in numerous 

 and widely distributed species; the slight difference in distance 

 between the eyes can be accounted for sexually. 



P. pascoei Macl., is also under suspicion as a synonym of /'.
