CERAMBYCID^E 257 



Bayfield, Wisconsin, which I have before me; in the former this 

 joint is stouter and very obliquely truncate, while in the latter it is 

 narrower, more elongate and transversely truncate; this may be 

 one of the normal sexual distinctions of the genus, but as I have only 

 two examples of americana, both females, in which the palpi are of 

 the Bayfield type, this cannot be decided at present. No such 

 sexual character exists, so far as can be observed, in Parallelina. 



Strangalepta n. gen. 



This genus consists, so far as known to me, of the 'species Uneola 

 and pubera Say, nibida Lee. and vittata Oliv. The first varies some- 

 what geographically and possibly indirecta Newm. may have to 

 be restored for the eastern representatives of Uneola, which are 

 much larger than those of the Mississippi Valley, probably forming 

 a subspecies. In Strangalepta there is an unusual development of 

 the tempora, this being observable in pubera, as well as vittata; they 

 are also subimpunctate and strongly shining as a rule, as in the 

 basalis section of Leptacmceops. In vittata there is a remarkable 

 male tibial character that does not seem to have been mentioned; 

 the hind tibia of that sex is broadly angulated within just behind the 

 middle. 



The following undescribed species has just been received: 



Strangalepta keeni n. sp. Form somewhat more abbreviated than in 

 pubera, the prothorax nearly as in Uneola, deep black throughout the 

 body, legs and antennae, the elytra bright rufous, with the tips, extending 

 forward narrowly and slightly at the sides, black; pubescence rather 

 sparse and inconspicuous, yellowish above, grayer beneath; head finely, 

 very densely punctate and dull, with a very fine smooth median line, 

 the eyes large and prominent, the tempora very much less prominent 

 than the eyes and only about a fourth as long though rather tumid and 

 almost impunctate; antennae slender, almost as long as the body, the third 

 and fifth joints subequal and much longer than the fourth; prothorax a 

 little longer than wide, campanulate, evenly convex, more strongly punc- 

 tured than the head and very densely, with a fine smooth median line, 

 broadly impressed medially at base, the basal angles laterally very promi- 

 nent and acute; elytra moderately cuneiform, about three times as long 

 as wide, one-half wider than the median part of the prothorax, the apices 

 transversely truncate, with blunt sutural and rounded external angles, the 

 surface very shining, the punctures coarse, gradually somewhat less so 

 posteriorly, everywhere very sparse, separated by about four times their 

 diameters; abdomen rather finely punctate, closely basally, more sparsely 

 distally; legs rather long and slender, the basal joint of the hind tarsi not
