two vague whitish spots, one near inner margin about one-third from base 

 and one beyond it in cell. These wings are cleft from about the middle, and 

 the lobes are somewhat narrow, so that in general appearance the species looks 

 like a Trichoptitus. Fringes fuscous at apex, becoming white toward base of 

 cleft and containing brown scales in cleft. Second lobe with tufts of fuscous 

 scales at apex, anal angle, and along inner margin. Outer margin with fringes 

 partly white, inner with fuscous fringes between last two tufts. Secondaries 

 brown, similar to primaries, with gray-brown fringes. Third lobe somewhat 

 paler, white beyond middle, with large tuft of blackish scales in fringes of 

 outer third. Expanse 18-20 mm. 



Distribution: California: we have specimens from Tulare and 

 San Bernardino counties and Lake Tahoe. Part of the type series was 

 taken in Oregon. Mr. G. O. Day sent in one 9 labelled Cowichan 

 Lake, Vane. Id., and the B. C. Entomological Society records the spe- 

 cies from the mainland. The specimens which we have examined were 

 taken from the eighteenth of Jime to the end of July. The Connecticut 

 record is probably based on a misidentification. 



Dyar's account of the life history is as follows: 



"Seven specimens, June 25, 27, 29, August 3. The young larvae were 

 found webbing the heads and deforming the leaves of a wooly herbaceous plant 

 with milky juice, Hicrachim albiflorum. The larvae were very small but made 

 a great showing as the whole head of the plant is webbed and distorted, the 

 leaves cnunplcd and the flower shoot does not grow up as it normally would. 



"Larva. — Head small, bilobed, pale honey yellow, mouth pointed. Body 

 robust, tapering a little at the ends, feet normal, slender, dilated at the ends as 

 usual in the Pterophoridae. Primary hairs simple, coarse, white, i and ii 

 closely approximated, the tubercles black ; iii single, iv and v closely approxi- 

 mated, vi single, the tubercles brownish ringed. Numerous small secondary 

 hairs all over, white, short, broadly clavate tipped. Olivaceous green, the food 

 dark; skin densely covered with minute black, flat granules; spiracles black 

 ringed. Later there is a deep brown spot on tubercle i + ii. 



"Pupa. — Attached by the anal extremity, free ; pale yellow, the tubercles 

 like those of the larva, the dorsal ones colored red. The young larva is with- 

 out the capitate secondary hairs." 



We have at hand a specimen compared by Mr. Meyrick with 

 Walsingham's type in the British Museum, the specimens, four in 

 number, which Walsingham placed in the Fernald collection, and a 

 specimen personally compared with Grinnell's series of bernardinus, 

 and are thus able to establish beyond reasonable doubt the identity 

 and synonymy of this easily recognized species. In Grinnell's col- 

 lection we foimd a series of five specimens over this name which were 

 apparently those referred to in his description. None of these was
