CERAMBYCID^E 305 



I place a North Carolina female, with narrow and rather shining 

 prothorax, having very moderate and rather evidently separated 

 punctures; it may not be exactly conspecific. The species of 

 Ilypermallus are evidently very numerous but form a difficult 

 study, and those above enumerated probably form but an insig- 

 nificant part of them. Some of the Mexican species belong to other 

 genera such as Anoplium. 



Anoplium Hald. 



The type of this group of species, which can very well assume 

 generic rank, is one of the most aberrant in having the pubescence 

 uniform and the antennal spines obsolete. An examination of 

 the apex of the third antennal joint shows, however, a sharply 

 marked and very acutely prominent angle at the position of the 

 usual spine, proving that the difference is only one of degree and 

 is not a radical departure in structure like that of Tylonotus, for 

 instance. Besides pumilum and inerme of Newman, masstum, 

 cinerascens and debile of LeConte, and truncatum of Haldeman, all 

 of which I have before me, the last being different from debile 

 and not identical as stated in our lists the genus will comprise 

 punctatum, spur cum and imbelle of LeConte, grisescens Bates, 

 reported from southern Florida by Schaeffer, cinereum Oliv., brevi- 

 dens, simile, subdepressum and niveivestitum of Schaeffer, and 

 possibly alienum Lee., which is however aberrant, the elytra 

 having long sparse flying hairs and being rounded at the apices, 

 with spiniform sutural angle; if not of this genus it constitutes in 

 all probability a distinct genus, still undescribed; it inhabits Arizona 

 and is 14.5 mm. in length. 



The following genus is rather puzzling in regard to its true 

 position. It does not seem to have been studied by Linell or 

 Schaeffer and is probably undescribed. 



Geropa n. gen. 



Body subparallel, rather slender, only moderately convex, not 

 densely but uniformly pubescent, with very evenly fusoid, bi- 

 truncate and completely unconstricted prothorax and very slender, 

 completely unarmed and moderate antennae, bristling with long 

 slender hairs; the eyes and general facies are somewhat as in
