DESCRIPTIONS OF NEW HYMENOPTERA. 



By T. D. A. COCKERELL, Las Cruces, N. Mexico. 



The types of all descriptions published under the above head 

 will be placed in the collection of the American Entomological 

 Society. 



These descriptions have been prepared at the suggestion of 

 Mr. Fox, without whose kindly aid I should not have been able 

 to attempt them. 



MUTHiLIDJE. 



Sphaerophthalma foxi n. sp. Ckll. <j\ Head black, rounded, subquad- 

 rate seen from above, punctured; cheeks with sparse, short, whitish hairs; 

 crown with rather sparse, fulvous hairs, becoming reddish on occiput; 

 eyes prominent, shining; antennas very dark brown. Thorax black, 

 punctate, sides with sparse whitish hairs, dorsum of pro- and mesothorax 

 with short, not at all dense, orange-red pubescence; metathorax punctate- 

 reticulate, with some long black hairs; first segment of abdomen sub- 

 nodose, more or less constricted at apex, punctate, dark brown, rather 

 sparingly hirsute with dark hairs. Abdomen ovate-subacuminate; above 

 and below, except the first segment and the blackish terminal one, bright 

 orange-red, with a short, not very thick pubescence of the same color. 

 Legs dark brown, femora punctate. Wings dark brown, the first two 

 submarginal cells, and a region below them, being distinctly paler. Mar- 

 ginal cell pointed at its proximal, and squarely and broadly truncate at its 

 distal end ; second submarginal receiving the recurrent nervure much 

 before its middle; second transverso-cubital nervure broken just before 

 the point of junction with the cubital, leaving the second submarginal cell 

 open; third submarginal cell incomplete by the failure of the lower two- 

 thirds of the third transverso-cubital nervure. Length 7-9 mm. ; of fore 

 wing 5-6 mm. 



Hab. luarez, State of Chihuahua, Mexico, close to the river 

 bank; two specimens running on the ground, Aug. 26, 1893 

 (Ckll.). 



Mr. Fox observes that this resembles somewhat S. fulvokirta t 

 but it is clearly distinct from that, and judging from the descrip- 

 tions, I fail to associate it very closely with any described species. 



As it was taken near the south bank of the river which flows 

 between the United States and Mexico, it is to be looked for 

 within U. S. territory, although it cannot yet be added to our 

 lists. 



Sphaerophthalma townsendi n. sp. Ckll. <$. Black, with bright orange- 

 red pubescence. Head 'rounded, pitch-black, shining, strongly punctate,
