process, sides sinuately narrowed to apex, posterior angles acute, 

 produced a little backwards and downwards into a short tooth, 

 antei'ior processes slightly overlapping, hollowed and narrowly 

 rounded at extreme point, enclosing head in a circle of less than 

 3 mm. diameter; foliate margins concave, strongly reflexed at 

 border, edge (seen sideways) thin and continuous with under 

 surface; disc convex, with central carina rising in a single curve 

 to its highest point near, but not at apex, posterior edge of 

 Citrina descending in a steep declivity tob;^se, head and prothorax 

 minutely and closely pustulose, base strongly trisinuate, edge not 

 crenulate. Scutellum transversely triangular and a little raised 

 in middle. Mytra {9 x 9 mm.) ovate, widest at middle, of same 

 width as prothorax at base, a,pex of each elj'tron separately 

 rounded; shoulders obtusely angulate, foliate margins as wide as 

 those of prothorax at base, narrowing to apex, concave for the 

 greater part but horizontal, not gibbous at base; extreme edge 

 reflexed, seen sideways narrow, convex, of same width as those 

 of prothorax and continuous with under surface; surface of 

 margins sublpevigate. Disc very convex, tricostate, with the 

 suture and two subparallel costse forming strong ridges of almost 

 equal height; sutnral costa continuous from base to apex, the 

 other two scarcely divergent at base and very little convergent 

 and abruptly ending on apical declivity, crenulate on sides; 

 between these costae and the sides are two subobsolete costte 

 continuous from base almost to apex, the junction of disc with 

 margins marked also hy crenulate impression, on the outside of 

 which is the line of large lateral punctures : whole surface of 

 disc coarsely and irregularly foveate-punctate, without linear 

 airangement, intervals coarsely, subreticulately rugose. Pro- 

 sternum little raised, posterior process flat and sulcate at sides, 

 abdomen minutely shagreened, under side of femora smooth, 

 tibiae rugose, not hairy, apical spines small. Dimensions, ^ 

 14x9 mm.; 9 16 x 10 mm.
