CERAMBYCID^: 373 



posterior part of the head and greater part of the pronotum, and 

 more widely separated antennee, but especially in the very different 

 vestiture of the head and prothorax, which parts in that species are 

 sparsely clothed with irregularly decumbent or less erect and very 

 coarse hairs, which are much paler in color. 



Clytopsis n. gen. 



The type of this genus is a species which I have had for a long 

 time in my collection under the name Clytus dimidiaticornis Chev.; 

 but, on comparing it more closely with the described characters of 

 that species, there seems to be no doubt of its distinctness; it differs 

 from Clytus in the much more prominent transverse frontal line 

 between the antennae and the consequently much steeper anterior 

 part, which is perpendicular; it also differs in the broadly truncate 

 basal margin of the eyes, stouter legs, relatively much less developed 

 head and prothorax and in the system of elytral ornamentation, 

 but agrees very well otherwise. The type may be described as 

 follows : 



*Clytopsis nimbata n. sp. Stout, only moderately convex, deep black 

 and opaque, the elytra feebly shining; legs pale ferruginous, the femora 

 broadly and feebly fusco-annulate near the apex; head with three bands 

 of yellow pubescence; antennae rather thick, two-thirds as long as the 

 body, pale, gradually thicker, more compact and blackish-brown distally, 

 the color transitional through the sixth and seventh joints, the basal 

 joint obconic and as long as the.next two, the second strongly obconic 

 and as long as wide; prothorax nearly one-half wider than long, broadly 

 rounded at the sides, narrowed and subtubulate at base, very finely, 

 densely, confusedly punctate and evenly convex throughout, with sparse 

 erect fuscous hairs and bright yellow apical and basal margins; scutellum 

 large, transversely rounded, densely yellow-pubescent; elytra very much 

 wider than the prothorax, slightly tapering, each with some longer looser 

 yellow hairs on the basal slope and a transverse, somewhat anteriorly 

 oblique yellow line near the base, not attaining the side or the suture 

 near the scutellum, a transverse, posteriorly and feebly arcuate fascia 

 a little before two-fifths, from the side bending rapidly forward internally 

 to the suture slightly behind the scutellum, another, finer, from the side 

 slightly behind the middle, feebly oblique and straight, then near the 

 suture abruptly and anteriorly extended to the suture at basal third, 

 another, broader and more transverse, just beyond two-thirds and finally 

 an apical transverse solid spot, the apices narrowly obliquely truncate, 

 with the angle rounded; under surface clothed closely almost throughout 

 with rather coarse, decumbent, more whitish-yellow pubescence. Length 

 11.0-15.0 mm.; width 3.4-5.0 mm. Mexico (Guerrero). 



This species differs from dimidiaticornis, so far as can be deduced
