Aphycus texanus COCKERELL and PARROTT (not Howard), Industrialist, May, 

 1899, p. 278. 



Female. Similar to A. texanus (Howard) in all respects but the 

 following: Front and vertex a little wider, about one-half longer than 

 wide, more coarsely alutaceous; the ocelli fully their own diameter 

 from the eye margin, the anterior ocellus considerably posterior to 

 the center of the front and vertex, the ocellar angle fully 90. Anten- 

 nal scape slenderer, the pedicel as long as the first four funicle joints. 

 Wings with the oblique hairless streak more narrowly separated from 

 the posterior margin of wing. Ovipositor protruded slightly more or 

 nearly one- third the length of abdomen. Length: 0.7 mm. 



Coloration entirely paler than in A. texanus, the notura of thorax 

 pale orange yellow, the head, underparts, and appendages still paler 

 yellow. Wings nearly hyaline, showing but a slight trace of a yellow- 

 ish cloud on basal half. 



Male. One poorly preserved male with the head missing shows no 

 marked divergence from the female in coloration. 



Described from three females, one male (type, allotype, and para- 

 types) reared from Pseudococcus gutierreziae (Cockerell), Las Cruces, 

 New Mexico (T. D. A. Cockerell), Insectary No. 7282 01 , all in poor 

 condition.
