tion and these are characteristic for the species. Only subfiavidalis 

 resembles it in the t. a. line, and none are like it in the course of 

 the t. p. line. 



The characters of the male are those of the series to which it 

 belongs, and the abdominal tuftings are as described for pyra/is. 

 The venation figured is of this species, and the hair tufting is as 

 shown in the picture. At the base of the primaries the tufting is of 

 flattened hair and scales, and forms a little mass at tip; the longer 

 hair from nearer the middle of costal margin is thin, fine and silky 

 and forms a covering or shield over the veins of the costal area. On 

 the secondaries the tuft comes from the membrane between veins 7 

 and 8, and consists of fine, thin, silky hair, forming two flattened 

 layers; the outer much hmger and tapering somewhat to a point. 

 The little tuft on vein 5 is more scale like and lies parallel with the 

 vein when the wing is at rest; it is upright as shown in the figure 

 when the wing is mounted and floats in a liquid medium. 



The tufting of the legs is also drawn from this species. The 

 median tibise are somewhat inflated and grooved upward and 

 inwardly; this groove concealing a tuft of long fine hair attached 

 at the base. At the edge of this groove is a fringe of shoit, scale- 

 like hair, which in part serves to close and protect it. The terminal 

 spurs are very unequal. The hind tibise are more nearly normal ; 

 but there is only a single terminal spur and there is a small hair 

 tuft at basal third. 



The antennae of inale have the usual scant pubescence, and in 

 addition each joint has an obvious lateral bristle on each side of 

 each joint; not so distinct as in reversalis by any means; but yet 

 readily noted. 



The examples from Yuma and Yavapai Counties, Arizona, and 

 from Walters Station, California, were all sent in by Mr. Hutson, 

 and are from similar desert localities. The Colorado locality I 

 know nothing about. 



Pleoiiectyptera parallela n. sp. 



Head and thorax reddish or fawn-gray, primaries more reddish. Head and 

 thorax without maikings, palpi gray tipped, more reddish basally. Primaries 

 with the median lines almost parallel, rigidly oblique from costa to inner mar- 

 gin, broad, yellow, outwardly bordered by a narrow brown line or shade. There 

 is no appearance of an s. t. line. No orbicular. No obvious reniform ; but there 

 is a vague shading at the end of cell which may indicate the occasional presence 

 of this mark. Secondaries shading from pale yellowish at base to the reddish-
