DESCRIPTIONS OF NEW SPECIES. 203 



The anterior one extends from the suture to the outer third, the 

 hinder one is entire. The eyes are completely divided, as in the 

 other species of the genus, with the upper portion small, narrow, 

 and oval.* 



ZAGYMNUS Lec. 



528. Z. clerinus. Niger, pube erecta pallida sat dense vestitus ; 

 supra confertiin fortiter punctatus, capite thoraceque rubris ; elytris pa- 

 rallelis, apice rotundatis sutura prominula, macula subscutellari fasciis- 

 que duabus latis auruntiacis, bis ad suturam interruptis et ad uiargineui 

 conjunctis; subtus uitidus punctatus. Long. 13 mm. 



* It is proper to note bere the occurrence in Texas of Gnaphalodes tra- 

 chyderoides Thorns., a remarkable Mexican species. Tlie genus belongs 

 to Group II of Cerambycini, and would be properly placed in the table 

 (Classif. 302) before Chiou. with the following definition : — 



Prothorax with lateral spine behind the middle ; antennae densely fringed 

 beneath, inner angle of joints 4-7 spinose ; elytra bispinose at tip ; 

 episterna of metathorax wide, scent pores distinct. Gnaphalodes. 



The scutellum is triangular, larger than in Chion, and the eyes are less 

 coarsely granulated : the presternum is perpendicular behind, and the 

 mesosternum convex. The body is brown, uniformly clothed with gray- 

 brown pubescence, paler and more dense on the scutellum. 



AlieflllS prolixilS. Piceus, dense breviter cinereo-pubescens et pilis 

 raris volatilibus pilosus, prothorace punctato, fere cylindrico, latitudine 

 ongiore, linea transversa tenui ante medium, tuberculoque utrinque 

 prope basin ornato ; elytris thorace latioribus, punctatis, punctis pos- 

 tice subtilioribus, alterisque majoribus piliferis intermixtis, apice longe 

 bispinosis ; antennarum articulis 3-G spina brevi armatis. Long. 25 

 mm. 



One pair, Cape San Lucas, Mr. Xantus. This fine species differs from 

 the others by the anteunse being armed with small spines ; they are very 

 distinctly carinate, in the % are nearly as long as the body, and in the 9 

 scarcely two-thirds as long. The under surface and legs are finely pube- 

 scent, and speckled with darker punctures from which proceed the flying 

 hairs. The 5th ventral of the % is slightly truncate, etnarginate. The last 

 joint of the palpi is elongate triangular, less dilated than in .1. volitans, 

 and transversely truncate ; the appearance of a transverse line across the 

 disk of the prothorax in front of the middle is the result rather of the 

 arrangement of the pubescence than of a positive elevation ; the tuberc'e 

 each side is transverse, near the base, and nearer the side than the median 

 line: there are a few large scattered darker punctures upon the sides. 



This fine species was overlooked in my boxes until too late to print the 

 description on p. 18(3, where it properly belongs.
