ACBOTHIXIUM. 461 



species is of somewhat broad, flattened shape. On more carefully 

 comparing my P. playiuia with Baly's type 1 find that it cannot be 

 separated.

 Pachnephorus couvexicollis. Eabi. Trans. Ent. Soc. Land. (3) iv 

 1867, p. 95. 



Dark aeneous or cupreous. Head coarsely and closely punctured ; 

 anterior border of clypeus distinctly 

 angulate-emarginate, hinder margin not 

 thickened, surface coarsely punctured. 

 Thorax broader than long, very convex 

 above, coarsely and closely punctured, 

 clothed with bifid scales ; sides obliquely 

 divergent from base to beyond the middle, 

 thence sharply rounded and convergent to 

 apex; middle of disc glabrous. Elytra 

 oblong-ovate, subcylindrical, strongly and 

 closely punctate-striate, interstices clothed 

 with white scales that form small spots. 

 Antennae, tibiie and tarsi more or less 

 fulvous.

Philippines ; Macassar. 



Much more elongate and narrowly subcylindrical than P. breting- 

 hami, the thorax strongly constricted at base, sides distinctly 

 angulate before middle. The species seems to have a wide 

 geographical distribution if indeed all really represent the same 

 form, but I am quite unable to separate Baly's type in the Brit. 

 Mus. from the European species ; this latter has also been recorded 

 as occurring in Ashanti (Weise, Ins. Deutschl.).

Range. India ; Japan ; China. 



Body subquadrately ovate, sparingly pubescent, hairs suberect. 

 Head broad, deeply inserted ; eyes round, feebly sinuate. 

 Antennre scarcely extending to middle of body, terminal joints 

 distinctly dilated.* Thorax transversely subquadrate. Elytra wider 

 at base than the thorax. Tibia? not emarginate at apex but 

 abruptly widened ; tarsi short, triangular ; claws appendiculate. 

 Prosternum broad, scarcely longer than broad, widened at the base.
