length from the base ; antennae long, feebly incrassate, rather loose, extend- 

 ing almost to tli<e end of the elytra, the basal joint a little lunger and thicker 

 than the second or third, the latter similar, subequal and elongate, four to 

 ten feebly obconical, very slightly increasing in width, the latter barely per- 

 ceptibly wider than long, eleventh not wider, as long as the two preceding 

 together ; ligular process slender, elongate, apparently simple ; labial palpi 

 well developed, the two basal joints subequal in width and strongly united. 

 Prothorax but slightly wider than long, widest near apical third where the 

 sides are broadly subangulate, feebly convergent and rounded to the apex, 

 equally convergent and straight to the base, the latter broadly, strongly 

 arcuate and as wide as the subtruncate apex ; apical angles deflexed, narrowly 

 rounded ; basal obtuse but distinct ; hypomera greatly visible from the side, 

 not extending to the apex ; disk transversely convex, very broadly, feebly 

 impressed in the middle toward base. Elytra large, slightly wider than long, 

 one-half wider and nearly one-half longer than the prothorax ; sides parallel, 

 very feebly arcuate ; humeri broadly exposed at base ; disk evenly convex, 

 not impressed, the suture strongly margined. Abdomen distinctly narrower 

 than the elytra but wider than the prothorax, much longer than the anterior 

 parts ; sides perfectly straight and parallel from the base to the apex of the 

 fifth segment, the latter fully one-half longer than the fourth ; first four 

 strongly impressed at base. Legs long, slender ; posterior tarsi long, a little 

 shorter than the tibiae, the first joint as long as the next two and rather longer 

 than the fifth. Length 4.7 mm. ; width 1.2 mm. 



New York. 



The middle coxsb are narrowly separated, the mesosternal process 

 very long and slender, subacute at apex, the metasternal short, but 

 slightly prolonged, rounded at tip and not attaining the apex of the 

 mesosternal, the isthmus short. This species appears to be con- 

 generic with rigidicornis, but the antennae are much less incrassate 

 and the terminal joint is more slender. 



ECHIDNOGLOSSA Woll. 



In conformity with the views of Mr. Fauvel, I have placed the 

 species previously described under the name Colusa Csy., in Wollas- 

 ton's genus, although it is difficult to understand the statement under 

 the original diagnosis of Echidnoglossa, to the effect that the elytra 

 are "greatly abbreviated," if the two genera are identical. Key 

 introduced some confusion, which seems to be still maintained in 

 the European catalogues, by placing the Corsican representative in 

 a hypothetical Echidnoglossa, having four-jointed anterior tarsi and 

 allied to Falagria ; the tarsi in the American species are all five- 

 jointed without the slightest doubt, and they are so described also by 

 Wollaston for the type-species occurring in the Island of Teneriffe.
