P^ALL AND COCKEKELL. 253 



New Mexico. A single specimen taken at Cloudcroft by Viereck. 

 Type in collection of Atner. Ent. Soc, Pliiladelphia. 



The species differs remarkably from all previously described in 

 the siibangulate sides and costiform intervals of the elytra. It may 

 follow corijinis in Horn's table. 



TENEBRIONID^. 

 Paratenetiis criiiitiiK n. sp. 



Smaller and slightly stouter than pundatus, with which it agrees 

 in a general way, but distinguishable as follows: Erect hairs numer- 

 ous and conspicuous, punctuation relatively a little coarser, very 

 noticeably coarser and denser on the abdomen ; autennal club not 

 darker, prothorax a trifle more transverse, sides a little more 

 rounded ; metasternum between the coxse but slightly longer than 

 the diameter of the middle coxal cavity, subequal to the post coxal 

 length of the first ventral segment and shorter than the second seg- 

 ment. In pundatus the erect hairs of the upper surface are shorter 

 and very sparse, being nearly confined to the marginal portions of 

 the thorax and elytra; the intercoxal length of the metasternum is 

 nearly twice the diameter of the middle coxal cavity and much 

 longer than any of the ventral segments. In crinitus tlie metaster- 

 num is almost as short as in fuscus, which species is, however, very 

 distinct by its subinflated elytra, more rounded sides of the prothorax 

 and absence of erect hairs on the upper surface. As indicated by 

 the very short metasternum the wings are rudimentary in fuscus and 

 it is probable that they are so, though perhaps in less degree, in 

 crinitus. In all the species of this genus, of which males are known 

 to me, the anterior tibise are in this sex strongly acutely toothed 

 at the middle of the postero-interior margin. 



A single example from Trout Spring, sent by Prof. Cockerell. 



MELANDRYIDtE. 



Carebara brevicollis n. sp. — Elongate, parallel, brown, finely punctate 

 and pubescent. Antennae less stout than in longula, the fifth joint fully, the 

 tenth nearly as long as wide. Prothorax very slightly more than three-fifths as 

 long as wide, width greatest very slightly before the base, where it is visibly 

 greater than that of the base of the elytra ; sides feebly rounded and rather 

 strongly convergent anteriorly, all the angles rounded; basal impressions dis- 

 tinct; between them and immediately before the scutellum a still smaller impres- 

 sion. Elytra four and one-sixth times as long as the prothorax, parallel, some- 

 what depressed, apex obtusely rounded. Length 6 mm. ; width 1.75 mm.
