or less distinct hyaline spot across the axillary cell, close to the axil- 

 lary incision, and reaching sometimes into the second basal; (5) the 

 well preserved specimens show, on segments 2, 3, and 4 of the ab- 

 domen, short, tuftlike interrupted crossbands of dark hairs, easily 

 abraded. I notice that in all my specimens the ends of second vein 

 and anterior branch of third are distinctly diverging, while they are 

 more or less parallel in arethusa. 



"1 have 5 specimens from Shasta, Cal. (Edwards), which some- 

 what resemble parcilogastcr, but are, on the average, a little larger 

 and broader, the axillary cell, the hyaline spots in the third and fourth 

 posterior cells smaller ; the tomentum on the abdomen is principally 

 yellow and not mixed white. The third posterior cell is not bisected, 

 but has a stump of a vein (as in pcccilogastcr). Is this again, a dif- 

 ferent species ? " 



Mr. Banks noted this unnamed species in the collection at the 

 Museum of Comparative Zoology and says that it is the same as 

 wilUst-oni, Coq., near which it is placed. 



Anthrax pilosa new species. 



Body color dull grayish black. The abdomen is almost entirely obscured 

 by dull yellow pile, beneath which is a yellow tomentum. The incisions have 

 a few black hairs, "and there are a few at the sides of each segment. The 

 hind borders of segments 2 to 6 are banded with a yellow brown tomentum. 

 There is a band of black tomentum on the second segment which does not 

 reach the lateral margins, a still smaller band on the third segment. Spines of 

 the thorax and scutellum yellow, the pile and tomentum yellow. Vertex black. 

 Frons and epistoma with very sparse black pile and yellow tomentum. Basal 

 joints of the antennae reddish, the third joint black and slightly longer than the 

 first two (fig. 15). Legs yellowish red, the tarsi darker. Coloring of wings 

 very pale yellowish brown and not sharply defined. The smoky hyaline spaces 

 blend in with the wing pattern. Occiput black with yellowish white tomen- 

 tum. Venter blackish, the hind margins of the first two segments marked 

 with red. The type has a small red spot on each side of the second segment. 

 Scutellum red, the base and sides black. 



Type. — U. S. N. M., Cat. No. 20738. Four specimens. 



Habitat. — Los Angeles Co., Cal. 



This species is nearer fjiliginosa than any other. The four speci- 

 mens in the National Museum were collected by Coquillett and 

 labelled A. alpha with a query.
