Type.—C2it. No. 21615, U.S.N.M. 



Host. — Agromyza laterella Zetterstedt. 



Fourteen females reared by P. R. Myers, May 16-18, 1916, from 

 puparia of the above-named host infesting Iris. 



The host of this species is European, and although I have been 

 unable to connect the parasite with any description of a European 

 Dacnusa., it may nevertheless prove to be already known there. 



Family BRACONIDAE. 



Subfamily Aphidiinae. 



TEIOXYS CUPRESSICOLA, new species. 



This species is very similar to coruscanigrans Gahan, but may be 

 distinguished from it as well as all other American species by the 

 fact that the antennae of the female are 12-jointed and those of the 

 male 13-jointed. 



Female. — Length, 1.65 mm. Black, smooth, polished; palpi, an- 

 tennal pedicel, and first flagellar joint, narrow basal band on all 

 tibiae, all tarsi basally, the first tergite and the two horns at apex 

 of abdomen more or less pale yellowish. Wings hyaline, the stigma 

 and veins pale. Head impunctate; viewed from in front strongly 

 arched above the eyes; eyes converging below, the face rather nar- 

 row, polished; clypeus smooth convex, the clypeal foveae large and 

 deep; malar space very short; thorax polished, impunctate; parap- 

 sidal grooves absent except at the lateral anterior angles ; propodeum 

 polished, distinctly areolated, the petiolar areola rather large, well 

 defined and five-sided; first brachial cell of the forewing nearly 

 effaced; abdomen longer than the head and thorax, smooth, pol- 

 ished, ovipositor sheaths bent downward and about as long as tho 

 anal prongs. 



Male. — Except for the 13-jointed antennae the male differs from 

 the female only in the usual sexual characters. 



Type-locality. — Riverside, California. 



Type.—Q^t. No. 21616, U.S.N.M. 



Host. — Cerosipha., new species on authority of Mr. A. F. Swain. 



Described from seven females and four males received from Mr. 

 A. F. Swain and reared according to Mr. Swain from an undescribed 

 species of Aphid infesting cypress (Cupressus) and belonging to the 

 genus Cerosipha. 



Subfamily Cheloninae. 



CHELONUS (CHELONELLA) PROTEUS, new species. 



Is apparently closest to atripes Ashmead, but differs by having the 

 basal joint of flagellum slightly more than four times as long as 

 thick instead of scarcely three times as long as thick; by having the
