ABT. 9 DIGGER WASPS OF GENUS PODALONIA — FEPtNALD 21 



nous margin ; first dorsal plate black with a ferruginous margin ; second, 

 segment ferruginous above and below; third segment ferruginous, 

 mottled or shaded with black, particularly behind; remainder of 

 abdomen black; it is probable that the distribution of ferruginous 

 will vary in different specimens. 



Wings: Fore wings fuliginous with violet reflection; hind wings 

 semihy aline basally, somewhat fuliginous beyond the veins; tegulae 

 piceous. 



Legs: Black; coxae, trochanters, femora and bases of tibiae with 

 erect hairs; tibiae and tarsi somewhat sericeous, with short, black 

 spines; claws rather ferruginous; no coxal tooth. 



Male. — Unknown to me. Cameron says: "The male has the clyp- 

 eus rounded at the apex, and bears, as does also the face, a sparse 

 silvery pile; and the petiole almost twice the length of the hind 

 coxae." None of these are particularly distinctive features. 



Length. — Females, 13 — 18 mm. 



Distribution. — Specimens in the British Museum are marked as 

 from North Sonora, Mexico. I have in my collection a female taken 

 on wild plum blossoms at Placita, New Mexico, 6850 feet, May 5, 

 1903. 



Types. — Cameron evidently had before him both female and male 

 (supposed) of this species. In the British Museum is a female 14J/^ 

 mm. long, properly marked for locality and collector, and labeled 

 Type in Cameron's writing, and another with the same locaUty and 

 collector and with the printed label "B. C. A. Hymen. IL Ammo- 

 pMla sonorensis, Cam.," but without Cameron's label in writing and 

 not marked type. It was probably in the lot studied by Cameron. 

 Of a male, I could find no trace except a mount of genitalia marked 

 as of sonorensis. 



This species is apparently far from common. The two specimens 

 in the British Museum and one in my own collection are the only 

 examples met with during an examination of nearly 8,000 specimens 

 of Podalonia. It is easily recognized by the clypeal teeth, the fuligi- 

 nous wings, and by the shape of the abdomen which is rather globu- 

 lar and rises sharply from the petiole. In fact, superficially, it 

 greatly resembles CMorion (Priononyx) iifoveolatum (Tashenberg) in 

 the last two features.
