center of the frontovertex, the posterior pair nearly their own 

 diameter from eye-margin and twice as far removed from occip- 

 ital margin ; face a little shorter than length of eyes, the head 

 being a little thinner anteroposteriorly than in texanus or 

 gutierreziae, the scrobes about the same ; eyes with a very fine, 

 short, sparse pubescence; antennae (fig. 2, A) about as in other 

 species of the texanus group, the pedicel, however, proportion- 

 ately longer and slenderer, or a little longer than the first four 

 funicle joints combined; mandibles (fig. 2, B and C) normal; 

 wings uniformly ciliated, the speculum somewhat wider below 

 and nearly connecting with the hairless streak on the posterior 

 margin ; ovipositor about one-third the length of abdomen, its 

 sheaths pubescent. Length, 0.9 mm., exclusive of ovipositor. 



Coloration almost uniformly pale yellow, about chrome lemon, 

 the appendages concolorous, with apex of ovipositor black ; wings 

 hyaline, the veins pale yellowish ; pubescence on head and body 

 about as abundant as in the other species of the group, but not 

 conspicuous except on face, where it is whitish or silvery. 



MALE 



Similar to the female, but the following differences may be 

 noted : Frontovertex slightly wider or about one-half longer 

 than wide, the ocelli in a slightly acute or almost equilateral 

 triangle. Coloration the same, except that the dorsum of the 

 abdomen at apex is orange yellow, separated from the paler base 

 by a narrow, transversely arcuate dusky band between the 

 vibrissae. Length, 0.7 mm. 



Described from two females, two males (type, allotype and 

 paratypes a and &) reared from Pseudococcus yerhasantae Essig, 

 May 12, 1915, Sespe Cafion, California (C. P. Clausen), Clausen 

 no. 67.
