Hah. — Fowler Bay, South Australia. 



Two specimens {^ and 9) have been sent to me by C. French, 

 Esq., who has kindly given me one ; the ^ is in his collection. 



As usual in the genus, the ^ in this species has the elytra much 

 more dilatate on the sides than the <^, and more emarginate at the 

 base, which gives them au altogether shorter appearance. The 

 elytra of the 9 are much more declivous towards the sides and 

 apex, and have altogether a more decidedly convex and less 

 rotundate form than those of the (J. It is allied to E. 2)oliti(s, 

 SI., and, comparing the 9, it may be noted that the prothorax is 

 the same shape, but E. concolor has the elytra much more convex, 

 less rounded on the sides, and far more widely rounded at the 

 apex.

In spite of the difference in shape between E. obesus, Macl., and 

 E. bipimctatus, Mac)., I am certain they are merely the sexes of 

 one species. It is found over a large area of country, I myself 

 having taken it on the Lachlan, Murrumbidgee, and Murray 

 rivers ; the type of E. hipuiictatus came from South Austialia, 

 and the type of Scaraphites howittii, Casteln., from Port Lincoln, 

 S.A. In all, I have collected thirteen specimens of this species, 

 the sex of all of which I have determined, and have found eight, 

 identical with E. bipunctatus, to be males ; and five, identical 

 with E. obesus, to be females. I have found specimens of both 

 sexes at the one spot about thirty miles south of the Murrum- 

 bidgee River at Narrandera. Like E. minor, Macl., it lives
