FALL AND COCKKRELL. 221 



distinctly alutaceous, with rather coarse rounded punctures which are separated 

 by about their own diameters. Prothorax slightly narrower than the head, 

 obviously transverse, sides straight and moderately convergent behind ; sculp- 

 ture similar to that of the head, except that the punctures are somewhat finer ; 

 median line narrowly smooth and Very finely subobsoletely sulcate. Elytra sub- 

 equal in width to the head, evidently longer than wide, surface scarcely at all 

 alutaceous, the punctures finer and less close than on the prouotum. Abdomen 

 very finely but not closely punctate. Length 6 mm.; width 1.4 mm. 



Described from a single pair taken at Cloudcroft by Mr. Knaus. 

 The male type has the sixth ventral broadly feebly emarginate. 

 This species must be closely related to arizonense Csy., to which I 

 refer a specimen taken by Towusend in the White Mountains (New 

 Mexico). This latter is larger, with head and prothorax blackish 

 like the abdomen, and the third antennal joint is fully twice as long 

 as the second and distinctly constricted at middle. In piciventre 

 the third joint is distinctly less than twice as long as the second and 

 not at all constricted. 



Stilictis ubiitiis n. sp. — Piceous, the extreme apical margin of the elytra 

 obscurely paler; legs and antennae rufotestaceous. Head dull, the punctures 

 dense, rather coarse, and more or less longitudinally confluent; beneath coarsely 

 densely punctate ; sides parallel for a short distance behind the eyes, then broadly 

 rounded ; base truncate ; labral teeth very long and acute. Prothorax, as defined 

 by the angles, subquadrate, thesides just visibly converging posteriorly; surface 

 densely confluently punctate, median line finely canaliculate. Elytra just visibly 

 longer than the prothorax, equal in width to the head, the punctuation rather 

 fine and not close, surface moderately shining. Abdomen finely sparsely punc- 

 tate and somewhat shining. Length 4 mm. 



Beulah, May 3 (Cockerell). 



The type is a male, having the fifth ventral segment unmodified, 

 the sixth with a subtriangular emargiuatiou which is somewhat 

 wider than deep, and narrowly rounded at apex. The species is 

 related to rudis in sculpture, but has a very differently shaped head. 



Palaminus amplipeiinis n. sp. — Yellowish testaceous, the abdomen 

 slightly darker. Size, sculpture and vestiture throughout nearly as in P. testa- 

 ceus, from which and all previously described forms it differs in its broader and 

 longer elytra; these being one-half wider than the prothorax and about twice as 

 long. 



Pecos. Collected by Prof. Cockerell. 



The type is doubtless a female, and has the terminal ventral seg- 

 ment completely devoid of any trace of an emargination. It should 

 stand near normalis, which of all our species approaches it most 

 nearly in size of elytra.
