1916] Miscellaneous Chalcidoid Ilymenoptera 297 



Marginal vein subequal to the elongate stigmal, somewhat shorter than 

 the postmarginal. Cephalic femora but moderately swollen. Parapsidal 

 furrows just indicated cephalad. Propodeum of moderate length, 

 with a median carina and no others except short rugse from its cephalic 

 margin; no spiracular sulcus. Cephalic coxa metallic at base laterad, 

 hind coxcc all metalHc. Propodeum without a neck, its caudal margin 

 rimmed. Abdomen produced beneath, conic-ovate. Mandibles tri- 

 dentate. 



Described from one female in the U. S. N. M., "Agricultural 

 College, Michigan, 7-26-1890." 



Type: Catalogue No. 19937, U. S. N. M., the above female 

 plus a slide bearing a head, a hind leg and a fore wing. 



Coccophagus cinguliventris Girault. 



■Male: In the male the yellow band on the abdomen is very short, 

 subobscure; the head and thorax more brownish. One male, two 

 females reared from Lecanium corni at Madison, Wisconsin, June 22,. 

 1915. (F. A. Fenton.) 



ARTHOLYTIS APATELiE and A. PIMPL.E Ashmead are syno- 

 nyms. The median carina of the propodeum is delicate. There is a 

 roimd fovea at cephalic margin of propodeum at mesal base of the 

 dehcate lateral carina. The propodeal spircale is round, small. The 

 second ring-joint is larger than the first; funicle joints widening dis- 

 tad, 6 largest, all wider than long and much shorter than the pedicel. 



Gonatocerus triguttatus new species. 



Female: Length, 0.85 mm. The ovipositor slightly extruded. 



Dull honey yellow, the wings hyaline, the following parts black: 

 Ocellar area, dorsal and ventral edges of the scape, fiagellum, marginal 

 and stigmal veins, abdomen, three round spots on thorax, the mesal one 

 between the axillae and ends of the parapsidal furrows (not on the 

 scutiim), the lateral ones on the axillae cephalad and laterad. Tibiae 

 darker than the rest of the legs, but not much more so. Scape consid- 

 erably but not greatly convexly dilated ventrad. Pedicel short, only 

 slightly longer than wide, shorter than funicle 1 which is subequal to 2 

 and longest (or slightly shorter than 2 which is thrice longer than wide) ; 

 funicle 3 subequal to 1, the others shortening in succession, S slightly 

 longer than wide. Fore wings of moderate width, their marginal cilia 

 moderately short, about an eighth of the greatest wing width. Head 

 and thorax glabrous. Scutum with an embrowned triangular scalelike 

 area on each side of the meson cephalad. Propodeimi with a pair of 

 delicate median carinas, widely separated and a distinct, curved "lateral 

 carina" which originates caudo-laterad of the minute spiracle. Scu- 

 telltim separated from the scutum by a transverse sclerite Avhich runs 

 caudad of the axillae and is longer than the postscutellum. Caudal 

 wings narrow.
