320 THE CANADIAN ENTOMOLOGIST. 



This is a very distinct and peculiar-looking species, the pronounced 

 curve to the first lobe of the fore wings, and the general slender aspect, 

 render it easily recognizable and distinct. It is interesting as coming 

 from an island. 



Pterophorus Hilda, n. sp. — Expanse of wings, 23 mm. Head and 

 antennas pinkish-buff; antennte annulated wiih black ; eyes black; thorax 

 and abdomen pinkish-buff or cream-buff 



General colour of wings varying from pinkish-buff, cream-buff to 

 olive-buff; there is a black dash at end of fissure, but not touching it, 

 somewhat crescent-shaped; a delicate shade (white) extends from here to 

 the costa, slightly diagonally, where there is another dark brownish dash 

 resting on the costa lengthwise ; there are indications of two or three more 

 spots between this and apex, obscure ; there is a delicate white shade 

 along the costa of the first lobe, and in the apex is a larger one, with a 

 white line extending from this to the anal angle ; the second lobe is of the 

 same general shade of colour, but is more largely intermixed with a white 

 shade, which in the outer half (in one specimen) is resolved into three 

 bands. Fringes white, mixed with black hairs. Hind wings of an even, 

 shining pinkish-buff; fringes long, concolorous ; legs white. 



Habitat: Santa Ana River, 5,500 ft. altitude, July 27 and 31, 1907, J. 

 Grinnell. San Bernardino Mountains, Calif, July 13, 14, and Aug. 3. 

 Five specimens, of which two are types in the author's collection. 



Named after Hilda Wood Grinnell, who took so much interest in the 

 Lepidoptera of the San Bernardino Mountains.

 and antennse cream-buff; eyes black; rear of head, thorax and abdomen 

 ochraceous-buff ; legs whitish, barred with ochraceous-buff. 



General colour of fore wings ochraceous-buff, with on admixture of 

 salmon-buff; a black dash at base of fissure ; four or five small black dots 

 in angle of second lobe, and several along the inner margin, not reaching 

 the base; fringes darker than the rest of the wing. Hind wings salmon- 

 buff, with shining scales and silky lustre ; fringes of all the feathers very 

 long, opaque, concolorous. Legs salmon-buff and ochraceous-buff, spurs
