gotan insects, and, from the above-cited evidence, I feel confi- 

 dent that a more thorough study of the matter, based upon the 

 examination of more of the primitive representatives of each 

 order than are at present available for study, will merely confirm 

 the contention that " honey-yellow to brown " was the prevalent 

 color among the ancestral Pterygotan insects. 



NOTES ON HYMENOPTER^A PARASITICA. 



By a. a. Girault, Glenn Dale, Md. 



Hypopteromalus percussor n. sp. — Female : Like the genotype but differs 

 as follows : the femora are metallic at proximal half (caudal ones nearly 

 entirely metallic), the flagellum is darker. Types compared. 



From two females reared from the larvae of Zotheca tranquilla, We- 

 natchee, Wash., June 22, 1916 (E. J. Newcomer). Types: Cat. No. 20,970, 

 U. S. Nat. Mus., the females on tags, hind tibise and heads on a slide. 



Eupteromalus sarcophagse Gahan. — Differs from Meroporus utibilis 

 Tucker in having the distinct' lateral carinse on the propodeum and the 

 much longer than wide propodeal spiracle (mandibles not compared nor 

 other parts) ; from Halisoa rufipes Ashm. in the cylindrical antennae, 

 lesser size and perhaps otherwise; from Meraporus dubtus Ashm. not at 

 all. Types compared. 



Neomphaloidomyia n. gen. Tetrastichini. — The same as Neomphaloides 

 but the scutum without a median groove, the antennse with four ring- 

 joints (i and 4 large, equal). Stylus of abdomen very long, nearly as 

 long as the ovipositor, which is extruded for a length equal to two thirds 

 of the abdomen and is no wider than the stylus (i. e., it's valves are not). 

 Tooth 3 of mandible truncate. Male scape compressed, with fine, sharp 

 saw-teeth along its ventral margin, 4 funicle, 3 club and ring-joints. 

 Genotype : Hyperteles polynemce Ashm. 



Neomphaloidella irvingi n. sp. — Female : Similar to Aprostocetus cana- 

 densis Ashm., but differing notably in that the funicle joints are twice 

 longer than wide. Second two ring-joints very short. 



One female, Springer, N. M. (C. N. Ainslie). Type: Cat. No. 21,011, 

 U. S. Nat. Mus., the female on a tag, the head on a slide.
