 twice as long as the second, both joints black pilose, base of the third joint very 

 elongate-conical. Occiput white tomentose. Thorax whitish tomentose and 

 short black pilose, front end pale yellow pilose, the usual bristles reddish ; pleura 

 in front aud front coxae yellowish pilose, that beneath each wing pure white. 

 Scutellum white tomentose, that at the base black, the bristles reddish. Ab- 

 domen black tomentose, that on front corner of segments two, three and four 

 broadly white, most extended on the fourth segment, that on apex of fifth seg- 

 ment deep yellowish, on apex of sixth and whole of seventh segment white; 

 pile of dorsum mostly black, that on sides of first segment, of anterior two-thirds 

 of the second, many of those On the fourth and all on the seventh segment white, 

 the rest black; venter white tomentose, that on bases of last three segments 

 largely black. Legs having front tibipe destitute of bristles, claws of front tarsi 

 minute. Wings hyaline at apex, the base brown, filling costal cell to apex of 

 auxiliary vein; outline of brown crosses marginal cell at two-thirds distance 

 from base of second vein to apex of auxiliary vein, crosses first submarginal aud 

 first posterior cells at about half way from small ci'oss-vein to apex of discal cell, 

 passing basally in discal cell to a point opposite the small cross-vein, then going 

 to middle of vein between third and fourth posterior cells, then to last third of 

 vein between fourth posterior and anal cells; apex of anal cell to base of fourth 

 posterior cell hyaline, apex and hind margin of axillary cell broadly hyaline; a 

 hyaline spot in base of marginal, in middle and base of first basal, in each end 

 of second basal, and in base of anal cell, also a hyaline spot on veins at bases of 

 first submarginal, first, third and fourth posterior cells, the latter spot not pure 

 hyaline; a subhyaline spot in costal cell before the humeral cross-vein. Length 

 11 — 13 ram. 



San Bernardino County, Cal. Two specimens in July. 



This is our nearest representative of the European Anthrax fenes- 

 trata, differing chiefly by the less extended brown coloring on the 

 wings. 



73. A. sabulosa n. sp. — Black, the face, first two antennal joints, apex of 

 scutellum, sides of abdomen broadly, venter, femora and tibipe reddish. To- 

 meutum of entire body ligbt golden-yellow, that on the venter lighter. Front 

 and face mixed black and yellow pilose, face but slightly produced below, pro- 

 boscis projecting half the length of its labelliB or less beyond the oral margin. 

 Antennae having the first joint twice as long as the second, base of third joint 

 very elongate-conical ; bristles of thorax and scutellum yellow, pile of front end 

 and sides of thorax, of pleura, breast and coxae yellowish. Pile of dorsum of 

 abdomen very sparse, mixed black and yellow, that of sides rather abundaut, 

 light yellow. Front tibiae destitute of bristles, claws of front tarsi very small. 

 Wings grayish hyaline at apex, the base yellowish brown, the outline of this 

 color not distinct, extending from first vein half-way between base of second 

 and apex of auxiliary veins, crossing obliquely to penultimate vein near base 

 of fourth posterior cell, leaving apical fourth of anal cell and nearly all of the 

 axillary cell in the hyaline portion, but sometimes the apex of the anal cell is 

 smoky-brown ; a large blackish cloud on veins at bases of first, third and fourth 

 posterior cells, and at base of the discal cell, also a smaller one at base of the 

 second submarginal and second posterior cells; sometimes there is a subhyaline
