angle, third furcsil distinctly shorter than the fourth which is about as 

 long as the first; tip of wing at the fourth furcal or close to it within sec 

 ond marginal cell; anterior basal cell as long as radial cell, discoidal 

 cell very narrow at basal half, rapidly widening toward apex, cubital cell 

 somewhat reniform in outline; first marginal cell nearly quadrangular, 

 much higher than wide and at least three times larger than the second. 



(3\ Genital plate longer than the genital segment, about 2^ times 

 higher than broa 1, front and hind margins convex, tip very narrowly 

 rounded, nearly acuminate; forceps about three times narrower than the 

 plate and one-third shorter, very slightly curved forward, not narrowing 

 apically, tip rounded. 



9- Genital segment nearly as long as the rest of the abdomen, upper 

 plate rapidly narrowing posteriorly and produced into a rather long, very 

 acute point, upper edge rapidly descending toward the point which is 

 straight; lower plate oonsiderabh' shorter and less acute at tip than the 

 upper plate; its lower edge nearly straight, gently ascending. 



I have seen a number of specimens, partly collected by Mr. 



H. K. Morrison in southern Ari 

 zona or Sonora, and partly by Mr. 

 Coquillett in Los Angeles Co., Cal 

 Subsequently many specimens 

 were found on Rhus trilobata in 

 the mountains of southern Arizona 

 by Mr. H. G. Hubbard and myself 



FIG. 9. Caiopkya triozomima. . J -; 



in the months of June and July. 



Readily known from the other species by the form of the 

 wings, the indistinct pterostigma and the coloration. 



Type. No. 8149, U. S. National Museum. 

 Calophya californica, n. sp. 



Length i.S mm. Vertex and thorax piceous or brownish, abdomen 

 (excepting genital segment and anterior dorsal segments) and underside 

 blackish; frontal cones whitish, antennae pale yellow except at tip, legs 

 pale vellow, femora usually with a black spot on the inner ano outer sides 

 near the tip. Vertex as in the preceding species, frontal processes decid 

 edly cone-shaped, longer than wide at base, more or less diverging toward 

 the tips which are rather acute; antennae a little thinner and more 

 slender than in the preceding, hardly as long as the width of the head, at 

 tip decidedly black. 



Wings oblong-oval, 2^ times longer than wide, greatest width at apical 

 third, tip rounded, though not broadly, nearlv hyaline with a tinge of 

 milky-white, uniform in color; veins rather fine, pale yellow, differing in 

 the following points from those of C. triozomima ; cubitus a little longer 

 and only 2^ times shorter than discoidal part of subcosta; a very distinct 

 and long pterostigma which is as long or longer than anterior basal cell ; 

 first furcal a little more curved, second furcal forming a slightly oblique
