NOTES ON THE PSAMMOCHARID.E DESCRIBED 



BY PROVANCHER, WITH DESCRIPTION 



OF A NEW SPECIES. 



BY S. A. ROHWER. 



Bureau of Entomology, Washington, D. C. 



The following notes on the types of the species of Psammo- 

 charidcx. described by Abbe Provancher, were made in June, 1915, 

 and presented with the hope that they will enable Hymenopterists 

 to understand these species better. The new species here described 

 had previously been considered to be minimi Provancher, but 

 is easily distinguished from that species as the following notes 

 will show. 



No types were definitely designated by Provancher, and in the 

 collection there is no indication as to which specimen is type. 

 In this paper the word "type," etc., is used in the sense of "«^lectro- 

 type." ' / 



Ceropales (superba Provancher) — robins oni Cresson. 



Type in Harrington collection; para type bearing yellow label 

 "766" Derniere Provancher Collection Public Museum, Quebec. 



The synonymy indicated by Fox is no doubt correct. 

 Ceropales minima Provancher. 



Type a male with blue label "124" (script) and yellow label 

 "1420" (printed) in Derniere Provancher Collection, Public 

 Museum, Quebec. 



This is very probably a dark form oi f rater na Smith, although 

 no specimens with as few yellow marks on the abdomen are avail- 

 able. In the type the dorsal aspect of the propodeum is granular 

 with a feeble, short, median sulcus, the posterior face is trans- 

 versely aciculato-granular ; the third cubital on the cubitus is 

 twice as long as the second, and on the radius but little shorter 

 than the second; the head is granular and has no median sulcus 

 on the front. 



Ceropales foxii, new species. 



In Fox's synopsis of North America Ceropales (Trans. Amer. 

 Ent Soc , vol. 19, 1892) this species will fall near femoralis Cresson, 



November, 1916.
