200 DESCRIPTIONS OF NEW SPECIES. 



Colorado, two specimens ; the markings of the elytra seem to 

 be precisely as in X. insignia, but are narrow, and the black ground 

 is sprinkled with short cinereous hair. The prothorax is more 

 rounded on the sides, and not at all constricted at base. 



This species is sometimes placed in collections as X. mormonus 

 Lee, to which it has a strong resemblance in form, and by the 

 indistinct markings, but differs by the asperities of the prothorax 

 being very much finer, and by the frontal umbo, which in X. mor- 

 monus is broader, more acute in front, flat on the main surface, 

 and margined by two sharp well-defined distant carinae. The 

 thighs are strongly clubbed, but do not extend to the tip of the 

 abdomen.

523. IV. torquatiis. Fusco-piceus pubescens, elongatus, prothorace 

 latitudine longiore, carinulis brevibus transversis, serie triplici sitis, 

 (quarura antica media major est), inargine apicali et basali, fasciaque 

 transversa ad medium flavo pubescentibus ; elytris apice breviter acumi- 

 natis, basi fasciisque tribus flavo-pubescentibus, antica a sutura paulo 

 ascendente, alteris retrorsum obliquis ; subtus flavo-fasciatus, antennis 

 pedibusque ferrugineo-fuscis, femoribus anticis dente subapicali spini- 

 formi armatis. Long. 11 mm. 



One specimen from Texas kindly sent me by Mr. A. Salle. 

 This species has the same form as N. erythrocephalus, but differs 

 by the coarser sculpture of the prothorax (which is also less 

 rounded on the sides), and by the bands of yellow pubescence ; on 

 the elytra the two hinder bands are more oblique backwards from 

 the suture, and the front one is directed as much forwards in this 

 species, as it is backwards in N. erythrocephalus. The front 

 thighs are armed beneath on the posterior margin at the tip with 

 a long slightly curved spine, represented in allied species, in the 

 form of an obtuse slightly prominent tooth ; the hind thighs ex- 

 tend to the tip of the abdomen. 



N. longipes ; Clytus long. Kirby, Fauna Bor. Am. iv, 176. 

 I have seen this species in Parisian collections named N.fulgura- 

 tus Thomson. It appears to be rare in the North, but more fre- 

 quent in Texas ; the dark-ground color of the elytra is sometimes 

 thinly suffused with white pubescence, especially towards the base.
