NEW FOSSORIAL HYMENOPTERA FROM NEW MEXICO. 

 BY T. D. A. COCKERELL AND WM. J. FOX. 1 



Sphserophthalma snoworum n sp. 



$ . — Length about 15 mm., anterior wing 11 mm. Head, thorax, 

 antenna? and legs black, with black pubescence ; abdomen ferrugin- 

 ous, the basal segment darkened. Head small, rounded ; eyes very 

 prominent, shining ; pubescence of vertex becoming brownish ; an- 

 tennal sockets directed outward and downward, producing the 

 appearance of a prominent tubercle immediately mesadof the inser- 

 tion of each antenna, beneath which there is a deep depression, 

 which is smooth and shining ; clypeus and cheeks subcancellate with 

 large, close punctures ; penultimate joint of labial palpus very broad ; 

 first three joints of flagellum about equal in length. 



Thorax irregularly cancellate with close punctures, moderately 

 hairy, the pubescence on the prothorax becoming dark brownish. 

 Tegulse shining black. Middle segment gradually rounded, not 

 carinate at the sides. Wings dark fuliginous, a hyaline streak across 

 the second submarginal cell, and a hyaline spot just outside of it. 

 Three submarginal cells, the second broadly subtriangular ; marginal 

 cell not extending further than the third submarginal ; second re- 

 current nervure almost obsolete. 



First abdominal segment shaped something like the head of a 

 vulture, its union with the second marked by a deep suture. Pubes- 

 cence of abdomen tolerably abundant, black on first segment, largely 

 black on dorsum of second, the rest shining ochraceous. Punctua- 

 tion of abdomen extremely dense, the shining articulating surfaces 

 of the segments minutely transversely striate, no doubt for purposes 

 of stridulation. Apex broad and rounded, with lateral keels. 



Hab. — Albuquerque, New Mexico, Aug., 1894 (Snow). It is 

 named after the Snows, father and son, who have contributed so 

 much to our knowledge of the entomology of New Mexico. Near to 

 S. apicalata Blake (err. typ. for apiculata ?) from Mexico, but is 

 larger, abdomen entirely reddish, and lacks the pale pubescence of 



1 The descriptions are entirely drawn up by Prof. Cockerell ; my part has 

 been chiefly the comparison of the species with the collection of the American 

 Entomological Society. — W. J. F.
