ART. 5 GENERIC EEVISION OF THE FOSSORIAL WASPS — PARKER 49 



Fox writes me as follows : " I carefully examined that interesting 

 dark brown specimen taken by Doctor Van Dyke at Meadow Valley, 

 Plumas County, Calif., and except for the color I can not separate 

 it from tibialis. I think, as Doctor Van Duzee suggested, it is just a 

 case of melanism. On the same date and at the same locality Doctor 

 Van Dyke collected 20 males and 2 females, which I have determined 

 as tibialis.''^ 



I have seen the specimen of which Mr. Fox here writes and I think 

 he is right. It is a male and entirely without maculations, but aside 

 from this fact it agrees in other respects with tibialis. 



SPECIMENS EXAMINED 



California: Meadow Valley, Plumas County (Doctor Van Dyke); Sierra 

 Nevada. 



Handlirsch reports this species from Nevada. 



STENIOLIA NIGRIPES Parker 



Steniolia nigripes Parkeb, Proc. U. S. Nat. Mus., vol. 52, 1917, p. 8. 



This species is not represented in the United States National 

 Museum. It is known only from the type, a male in the collection of 

 the Academy of Natural Sciences, of Philadelphia, taken at Los 

 Angeles, Calif. Its distinguishing characters are the black apical 

 segment of all tarsi and the peculiar form of the spines of the eighth 

 sternite. 



STENIOLIA SULFUREA Fox 



Steniolio snlfvrea Fox, Jouvn. N. Y. Ent. Soc, vol. 9, 1901, p. 84. — Parkbsj,^ 

 Proc. U. S, 'Nat. Mus., vol. 52, 1917, p. 9. 



This species is not represented in the United States National 

 Museum. So far as I am aware it is known only from two males 

 (one the type) in the collection of the American Museum of Natural 

 History, taken in California. It is distinguished by having the 

 entire abdomen, except the basal part of the first segment, bright 

 sulphur yellow.

 Dalla Toree, Cat. Hym., vol. 8, 1897, p. 501. 



In his description of this species Say points out the presence of 

 black upon both clypeus and labrum. In his description and dis- 

 cussion of this species Handlirsch fails to note these characters, 

 although he had before him 20 males of the species. Say's descrip-
