Uracanthus lateroalbus, n. sp. 

 PL xxxii., fig. 15. 



<S . Of a rather dark castaneous. Densely clothed with 

 stramineous and white pubescence. 



Head with median line narrow, deep, and terminated 

 near base, the latter densely granulate-punctate; muzzle 

 shorter than usual; clypeus densely punctate, suture deep, 

 semi-circular and rather wide. Antennae moderately long, 

 fourth to tenth joints produced on one side at apex. Pro- 

 thorax about one-fourth longer than wide, sides moderately 

 rounded in middle; densely and strongly corrugated, but 

 irregular about . middle. Elytra moderately robust, their 

 median half almost parallel-sided, each notched at apex, with 

 the suture strongly dentate and the outer edge margining 

 the notch subtriangular ; each with several very feeble eleva- 

 tions or remnants of same; with very dense small punctures. 

 Legs comparatively stout. Length, 29 mm.

A comparatively robust species, with stouter antennae 

 than usual, the antennae, however, are damaged, but ten 

 joints remaining on one side and four on the other; possibly 

 examination of a specimen with complete antennae would 

 indicate that it should be referred to Scolecobrotus. The 

 pubescence on the head is somewhat ochreous and denser 

 between the eyes than elsewhere ; on the prothorax it is 

 nowhere vittate in character, but is darker on the disc than 

 at the base, apex, and sides; on the scutellum, and on the 

 elytra for a narrow space along the suture, the pubescence 

 is whitish, and on each side there is a conspicuous marginal 

 snowy stripe throughout; from the shoulder to about the basal 

 third the stramineous pubescence is sparser than elsewhere, 

 so that, to the naked eye, there appears a short subglabrous 

 stripe; the pubescence on the under-surface and legs is mostly 

 white. 



The four hind femora are densely clothed with somewhat 

 ochreous pubescence along the under-surface, and along the 

 middle of each there is a brownish glue-like substance : it is 

 not accidental, as it is alike on the four femora, and I have 

 seen a similar substance, or traces of it, on the males of 

 several other species; it is probably a secretion used for sexual 

 attraction.
