316 EE VISION OF THE GENUS ^^OTONOMUS, 



median line strongly impressed; lateral basal impressions narrow, 

 rather long; lateral basal spaces convex. Elytra truncate-oval 

 (8-5 X 5-2 mm.), rather depressed on disc, abruptly declivous on 

 lateral declivities; deeply striate; sides lightly rounded: lateral 

 sinuosities of apex feeble; shoulders rounded; basal border slightly 

 raised above lateral border at humeral angles (hardly subdentate); 

 interstices convex, third, fifth and seventh a little wider than 

 others, third 4-punctate, eighth narrow, not as wide as ninth; 

 tenth interstice and ninth stria well developed. Prosternum not 

 bordered on anterior margin; basal declivity narrow in middle, 

 bordered on sides: mesosternum wide, not concave between coxaa. 

 Posterior tibiae lightly incurved near apex. Length 15, breadth 

 5 2 mm.

A distinct species. I believe it to be Omaseus o'l/Jipalpis , 

 Casteln., the only apparent differences from Castelnau's descrip- 

 tion being that it is a little larger, and the third interstice of the 

 elytra has four — not five — punctures in both my specimens ; 

 neither difference appears to me of specific value.

Elliptical, parallel, depressed. Upper surface cupreous; pro- 

 thorax and lateral channel of elytra brighter than disc of elytra; 

 under surface, inflexed margins of elytra and legs piceous-black. 

 Head not large (4 mm. across eyes); front strongly biimpressed 

 behind clypeus; eyes convex, but not prominent; postocular parts 

 of orbits rising gently from head, not protuberant. Prothorax 

 quadrate (5-6 x 5-8 mm.), widest before middle, wider across base 

 (4*7 mm.) than apex (4*4 mm.) ; sides very lightly rounded 

 anteriorly, gently narrowed posteriorly and meeting base obliquely 

 without perceptible sinuosity; basal angles obtuse, but marked; 

 base emarginate in rbiddle; posterior marginal puncture placed
