species is of somewhat broad, flattened shape. On more carefully 
comparing my P. plagiata with Baly’s type I find that it cannot be 
separated.

Pachnephorus convexicollis, Paly, 'Trans. Put. Sue. Lend. (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, tibiae and tarsi more or less 
fulvous.

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.).
