THREE NEW BRITISH CHALCIDOID HYMENOPTERA: 

 WITH NOTES. 



By a. a. Girault. 



1. Coccophagus hriUanlcus, n. sp. 



Female. — Length, 0.75 mm. 



Valves of the ovipositor exserted a short distance. Black, the 

 vertex, distal third and lateral margins of scutum, parapsides except 

 a dot at mesal margin near (not at) cephalic end, and the scutellum 

 bright golden yellow. Legs pale except caudal coxa and femur, 

 caudal tibia just below the knee, distal tarsal joints and middle 

 femora and tibice at base (dusky scaly). Fore wings with a lightly 

 infuscated band across from the whole of the marginal vein. 

 Eunicles 2 and 3 subequal, each nearly twice longer than wide, 1 

 distinctly shorter somewhat longer than wide, more or less subequal 

 to the pedicel. Club joints subequal to each other and to funicle 3. 

 Flagellum subfiUform. Longest marginal cilia of the fore wing 

 about a third of the greatest width of those wings, somewhat shorter 

 than the caudal fringes of the caudal wings, the latter Vv^ith about 

 five lines of discal cilia where broadest. Stigmal vein longer than 

 wide, parallel with the cephalic margin, of about uniform width. 

 Fore wings with uniform discal cilia. Mandibles tridentate. Mar- 

 ginal vein rather thick, a little shorter than the submarginal. 



Described from three females on a slide with Apterotrix 

 longiclava, Girault. 



r^i^es.— Catalogue No. 19632, U.S.N. M., the above speci- 

 mens. 



2. Coccophagus niger, Masi. 



This species differs from immaculatus, Howard, mainly in having 

 the coxae black ; its sculpture I have not seen. The venter has 

 much yellow. A female reared at Manchester from Lepidosaphes 

 idmi (A. D. Imms). 



3. Phycus testaceus, Masi. 

 This species was reared with the preceding. 



4. ApheUnus mytilaspidis, Le Baron. 

 What appears to be this species was also reared with the pre- 

 ceding. 



5. Aphidencyrtas aspidioti, Girault, hrittanicus, n. var. 



Female. — Almost exactly similar to asjndioti, Girault, but there 

 is very shght staining along the marginal vein, and the frons is 

 somewhat broader. The species runs close to Encyrtus liyalini- 

 pennis, Mayr, and may be that species, yet the caudal knees are 

 not white (only the base of caudal femur), and the distal halves of 

 the first two tibi^ are not white because the middle tibia should 

 be described rather as being somewhat broadly banded with black
