7 (8). Upper-sido usually brouze-black ; elytra with an obscure suffused 



oval yt'llow-brown patch on the outer side of the front half of the 

 apical slope, bounded outwardly by the eighth interstice and con- 

 tinued as a broad piceous stripe to the apex ; the striae fine and 

 feeble, the second failing- at or before the commencement of the 

 apical slope, the third and fourth barely reaching the foremost 

 umbilicate pvincture ; frontal keels uneqvial and not straight, the 

 outer ones usually furcate at one or both ends. Lengtli 4'5 mm. 



strigifrons, Baudi. 



8 (7). Upper-side bronze; pale markings at the apex of elytra very obscure, 



only visible liy transmitted light, strise moderate, the second con- 

 tinued well over the apical slope, sometimes nearly to the apex, 

 the third and fourth usually reaching the foremost umbilicate 

 puncture ; frontal keels equal and straight, furcation of the 

 outer ones exceptional ; male with the last joint of the labial palpi 

 (in the widest aspect) obliquely truncate, less than three times as 

 long as its distal edge, the lower side straight, the upper edge 

 ciirved and much longer than the lower ; and the first joint of the 

 middle tarsi well clothed with special hairs. Length 5 mm. 



imsillus, Wat. 



9 (2). Tibiae red-yellow, becoming dusky towards the base and apex. 



10 (11). Elytral strise coarse, very evidently evanescent towards the apex, the 



outer interstices smooth ; middle lobe of the sedeagus a little con- 

 stricted jvist below the apex, the latter (when the organ is viewed 

 with its convex svirface uppermost) with a distinct notch a little 

 to the right of the middle, the right-hand angle rounded off, the 

 the left-hand angle prodiiced into a blunt recurved point, the con- 

 vex surface uneven and coarsely longitudinally rugose ; male with 

 the last joint of the labial palpi (in the widest aspect) distinctly 

 narrowed towards the apex, about three times as long as its oblique 

 distal edge palust ris, Duf t. 



11 (10). Elytral striw finer, only slightly evanescent towards the apex, the 



outer interstices finely shagreened ; middle lobe of the ffideagus 

 a little contracted just below the apex, the latter (when the organ 

 is viewed with its convex surface uppermost) evenly curved, the 

 right-hand angle with two or three small sharp recurved teeth, 

 the left-hand angle produced into a blunt recurved point, the 

 convex surface comparatively smooth ; male with the last joint of 

 the labial palpi (in the widest aspect) not narrowed towards the 

 apex, about two-and-a-half times as long as its oblique distal 

 edge hypocrita, Spaeth. 



12 (1). Second interstice at least as wide as the next three together. 



13 (18). Elytra pale at the apex. 



14 (17). Fourth interstice, near its half-length, twice as wide as the fifth.
