458 CASEY 



margin of the prothorax is entirely obliterated in Craniotus^ 



more completely so than in Edrotcs or any of the small types of 



Triorophini, and this character it shares with Adesmia ulcerosa 



Klug, but in Adesmia nitcrocephala Sol., there is a perfect and 



acute side margin as in Trioi'ophuSy this differential feature 



probably serving in part as a basis for the subgeneric divisions 



proposed by Allard. The Adesmiini suggest, through a widely 



diverging line of development, some of the Asidince. The only 



known genus of the Craniotini may be defined as follows : — 



Body narrow anteriorly, with inflated elytra, pubescent; head dilated 

 and acutely prominent at the sides before the eves, the latter 

 transverse, convex, coarsel} faceted and unemarginate as in 

 Edrotes and even more prominently projecting from the flanks ; 

 surface with a broad and deep transverse groove behind the epi- 

 stoma, which is broadly trapezoidal and but little produced, the 

 apex feebly sinuate; mandibles obtusely bifid at tip, impressed 

 externally, folding entirely beneath the exposed and apically 

 sinuato-truncate labrum ; mentum large, transversely hexagonal, 

 deeply sinuate at apex and emarginate at base ; antennas rather 

 long and slender, with the third joint much elongated as in 

 Adesfnia^ the eleventh not free but small and received within 

 the apex of the tenth, the latter being the only broadened joint; 

 prothorax transversely suboval, not beaded at apex, base or sides ; 

 scuteUum well developed, acutely pointed and elongate; elytra 

 embracing the sides of the body as in Edrotes^ the epipleurai 

 very narrow and linear but, as in Edrotini, confined to the pos- 

 terior part of the elytra, gradually disappearing before the middle 

 of the abdomen ; anterior coxae moderately separated, the inter- 

 mediate a little more widely and the posterior remotely separated, 

 briefly, transversely oval, separated from tlie sides of the body by 

 three-fourths of their own width ; metasternum very short, convex 

 at the sides, the met-episterna wide, subparallel, with the suture 

 internally arcuate ; femora and tibite very long, slender and sub- 

 cylindric, the hind tarsi comparatively short, slender, with long 

 hairs above and shorter stiff spines beneath, not grooved. [Type

The eyes in Adesmia^ although similarly transverse and con- 

 vex on the flanks, are feebly sinuate anteriorl}^ and are much 

 more finely faceted ; the apical parts of the head and mandibles 

 are almost similar, except that the front is not dilated at the 

 sides and the mentum not emarginate at base, and the eleventh 

 antennal joint is free, though very small. The coxa,' and meta- 

 sternum in Adesmia are almost exactly as in Craniotus, but the 

 posterior are still more widely separated, almost globular in
