In general appearance somewhat like bivittatus and 

 marginellus, but tips of elytra evenly rounded, and with the 

 suture very feebly produced (scarcely spinose). Of the seven- 

 teen specimens before me the tips are never emarginate, but 

 they vary from a form in which each is distinctly rounded 

 (fig. 9) to one in which the suture- is slightly produced 

 i(fig. 8). The clothing is also different to the usual form of 

 ■bivittatus, whose prothoracic vittae are not continuous to 

 apex. The scutellum and suture are usually darker (some- 

 times almost black) than the adjacent parts. There are four 

 wide stripes of pubescence along the prothorax : one on each 

 side of middle and one along each side, the intervening spaces 

 are highly polished and almost (or quite) glabrous; the 

 median glabrous space is usually, but not always, conspicu- 

 ously dilated towards the base, the dilated space being almost 

 oval in outline; on ten specimens it is non-corrugated and 

 with but a few small punctures, and the base is almost with- 

 out corrugations, but on several specimens there are some 

 distinct ones there, but the surface gradually changes till it 

 is almost entirely irregularly corrugated ; the disc of the 

 Albany specimen might almost be regarded as vermiculate, 

 with a short but distinct median line. The elytra appear to 

 have three brown lines from base to apex : one sutural 

 (common to both) and one near each side, but these lines are 

 really due to their covering pubescence being much sparser 

 than elsewhere. The false suture of the eleventh joint of 

 antennae is rather distinct on some specimens and scarcely 

 traceable on others. The size is very variable.

<$ . Piceo-castaneous. Irregularly clothed with whitish 

 pubescence. 



Head with median line \iery narrow, base densely granu- 

 late-punctate ; clypeus subtriangular, with a few small 

 punctures, suture deep and rather wide. Antennae very 

 thin, almost extending to the tip of etytra, fifth to tenth 

 joints triangularly produced on one side at apex, eleventh 

 about one-fourth longer than tenth. Prothorax much longer 

 than wide, base conspicuously wider than apex, sides feebly 

 bisinuate ; conspicuously multi-corrugate, but somewhat 

 irregular about middle. Elytra at base not much wider than 

 prothorax, sides regularly decreasing in width to apex, where 

 each is strongly emarginate and acutely bispinose ; densely
