Resembles Platypedia luoliavensis in having a relatively small head and 

 protruding front. The uncus is bent downward at the extremity, slightly 

 ridged on the dorsal surface; when seen in profile the lower line is sinuate and 

 the basal third is without the deepened area to be found in putnami and 

 areolata. Last ventral segment of the male rounded at apex ; valve shorter 

 and more robust than in mohavensis. Last ventral segment in the female with 

 the notch somewhat U-shaped and in form about as in mohavensis, that is not 

 as broadly open as in areolata and putnami. The pale markings of the body 

 are those common to the genus, as already mentioned. In iiwJiavensis the 

 venation of the fore wings is almost entirely black except the costal margin to 

 the end of the radial area, while in the present species the vein separating the 

 ulnar areas from the radial area is orange ; the veins surrounding the last two 

 ulnar areas are also almost wholly orange, while the veins surrounding the 

 marginal areas are nearly all black. The membranes at the base of the fore 

 wings are bright orange. The venation of the hind wings is pale, except about 

 the marginal areas, where it is nearly entirely black. 



Measurements in Millimeters. 



Male Type. Female Allotype. 



Length of body 18.5 17.5 



Width of head across eyes 5 5.25 



Expanse of fore wings 40 42 



Length of valve 3.5 



In addition to the type and allotype five females have been ex- 

 amined, collected in Los Angeles Co., California, May (Coquillett). 



In the collection of the California Academy of Sciences there is a 

 large male with wings expanding 52 millimeters, from Bear Lake, 

 San Bernardino Mts., California, May 17, 1919 (J. O. ^Martin), that 

 is considered here on account of the form of the uncus which resem- 

 bles that of the type of nifipcs except that it is much straighter along 

 the lower line. The front of the head is prominent ; the fore femora 

 are chestnut colored, darkened beneath ; femora of middle and hind 

 pairs of legs striped with black; tibiae blackened at the basal joints. 

 The fore wings have the costal margin bright orange to the end of 

 the radial cell, but the remainder of the venation is darker than in the 

 seven specimens of nifipcs. This insect may belong to a distinct 

 species.
