" TIjis species has most resemblance to L. posticata, from which it may 

 be distinguished by the pale hairs oa the hind tibise." 



I owe to the kindness of Mr. Henry Edwards male and female speci- 

 mens from Vancouver Island, which I refer to this species, although 

 some of the statements in the description do not quite agree with them. 

 It is very like L. astur, but it has a band of black pile across the middle 

 of the thorax. 



3. Laphria vultur n. sp., <? $ . — Whole body clothed with reddish- 

 fulvous pile, especially dense on the abdomen ; legs black ; the black of 

 the thorax as far as visible among the red pile has a bluish opalescent 

 reflection. Length 15-20'"">. 



There is but little to add to this diagnosis. The abdomen, especially 

 in the female, is much more slender than in L. astur. The front legs 

 on their hind side, sometimes also the middle legs are clothed with red- 

 dish-fulvous pile ; much more in the male than in the female. The wings 

 are hyaline on the proximal, infuscated on the distal half. Male forceps 

 beset with reddish-fulvous pile. 



Jjal). — The woods of the Coast Range, above Santa Cruz, Cal.,May 23 ; 

 "Webber Lake, Sierra Nevada, July 27. I received a specimen from 

 Oregon from Mr. H. Edwards; two males and one female. 



4. Laphria rap ax n. sp., <?. — Head, posterior part of the thorax, and 

 two first abdominal segments with whitish, the remainder of the abdo- 

 men, except the genitals, with ardent rufous pile; legs black. Length 



OAmm 



The lower part of the head and the base of the proboscis beset with 

 whitish pile; face likewise, but many black, erect hairs are mixed with 

 the white ones ; hair under the antennse altogether black. Front part 

 of the thoracic dorsum with short, black pile ; the hind part with longer, 

 semi-recumbent, whitish pile ; scutellum with some whitish pile ; male 

 forceps very large ; wings, as usual, brownish on the distal half and 

 hyaline on the proximal. 



Hab. — Webber Lake, Sierra Nevada, July 28, A single male. 



Lampria. 



Lampria FELis n. sp., 2. — Head, thorax, base of the abdomen, and 

 coxae black ; the rest of the abdomen and the legs red ; wings tinged 

 with brownish. Length 11""°. 



The pile on the head is altogether black, except a small tuft of silvery 

 hairs on each side, above the mystax, near the eye. The black of the 

 thoracic dorsum shows a bluish opalescence, a pair of small spots of 

 silvery pollen anteriorly, and another pair of less distinct, similar spots on 

 the humeri. Halteres yellow. First abdominal segment and a large 

 semi-circle on the second bluish-black. Alula and the proximal part of 

 the axillary cell hyaline.
