fovea in medio carinata, scrobe curvata oculum baud attingente ; 
capite in medio longitudinaliter impresso ; prothorace cpiam 
longiori fere duplo latiori, leviter canaliculate, vermiculato-rugoso ; 
scutello vix perepicuo ; elytris fortiter convexis, subrotundatis, 
basi vix (in medio fere duplo) prothorace latioribus, obscure sat 
crasse seriatim punctulatis, interstitiis subinterruptis minus con- 
vexis, horum nonnullis postice elevatioribus vix tuberculatis.

In a fresh specimen the sculpture is almost entirely buried under 
the squamosity, which is of a dull brown colour except a wide 
lateral vitta (indented three or four times within on the elytra), 
and a short narrow vitta on either side of the middle common to 
the prothorax and elytra, which are grey ; the squamosity of the 
underside and legs is greyish rather than brown. But only two 
of the specimens before me are thus clothed, the rest being older 
and more or less abraded, and in them the variegation of the 
surface is not (or very little) noticeable. In a very much abraded 
specimen the rostrum appears tricarinate above (the lateral carinse 
being wide and feeble) and it is probable that this sculpture 
always underlies the squamosity. The eyes are very narrow, 
vertical and acuminate beneath, the ocular lobes very strong. The 
triangular apical plate of the rostrum is strongly punctured and 
concave down the middle. This species has very much the facies 
of a Ciieorhinns. 
The genus Zyniaus is very briefly characterized by Mr. Pascoe, 
as follows ; “A Leptope difiert unguiculis connatis.” The present 
species does not bear the slighest resemblance other than structural 
to his species ( Z, hiaodosus ), but as I can discover no other 
structural character than that mentioned by Mr. Pascoe, to dis- 
tinguish it from Leptops, I have no alternative but to call it by 
the name Zymaus.
