HYMENOPTEROUS PARASITES. 1895 



are spoiled. Structurally it is identical with tiie other forms. Coloration- 

 ally it was described by Professor Riley in the following words : "It is in- 

 conspicuously marked, the body being dark brown, with the antennae and 

 legs pale, and the wings iridescent. 



The species was figured and described in the Third Report on the Insects 

 of Missouri, p. 157, from specimens reared from the eggs of Basilarchia 

 archippus in Missouri. From four to six parasites issued from each egg. 



Trichogramma minutissimum Packard, 



Body uniformly pale testaceous or lioney-yellow, legs and antennae scarcely paler 

 than the body. Abdomen a little longer than the thorax, but no wider, seen from 

 above. Antennae a little longer than in iniuutum, legs a little slenderer. Length, $ 

 .25 mm. to .37 mm. ; $ , .38 mm. -.5 mm. (After Packard.) 



[The following description of the colors was taken during life : — Body and head 

 wax-yellow ; face a little paler : eyes and ocelli dark orange ; body with yellow-green 

 internal blotches appearing through the skin ; legs and antennae pale yellow, apical 

 half of tarsi a little dusky, s. h. s.] 



In the material sent me by Mr. Scudder I find eight slides of this 

 species, three labelled from eggs of Jasoniades glaucus, three from eggs of 

 Basilarchia archippus, and two from eggs of Vanessa atalanta. 



Trichogramma intermedium sp. nov. PI. 89, fig. 8. 



Male. — General color dirty yellow in effect; face bright yellow, eyes and ocelli red, 

 antennae slightly dusky ; mesonotum very light yellow-gray ; metanotum yellow ; ab- 

 domen above slightly darker than mesonotum ; all coxae dusky, hind femora slightly 

 dusky above, remainder of legs dull yellowish. Wings with a slight cloud below sub- 

 marginal vein. The nearly straight line of hairs running downwards from tip of 

 stigma consists of five hairs, the first one sometimes included in stigmal club, leaving 

 only four apparent in the row. Average length, .55 mm. ; average expanse, 1.0 mm. 



Female.— SWgtitly smaller, and not quite so dark as male. 



[The following description of the colors was taken during life : Honey-yellow, the 

 abdomen pale and banded transversely with dusky ; eyes and ocelli salmon-red ; legs 

 and antennae greenish olive; apical two-flfths of tarsi fuscous, s. h. s.] 



Of this species Mr. Scudder has sent me six slides, four containing 

 specimens reared from eggs of Aglais milberti, and two from eggs of Thanaos 

 lucilius. Mr. James Fletcher has since sent me from Ottawa four speci- 

 mens reared during the summer of 1888, from eggs of Oeneis macounii. 



FAMILY PROCTOTRUPIDAE STEPHENS. 



Genus TELENOMUS Haliday. 



Small, black, compact; abdomen acutely margined along the sides; antennae arising 

 near the border of the mouth ; anterior tibiae with one spur ; anterior wings with a 

 marginal and a stigmal vein; antennal club jointed; marginal vein shorter than stig- 

 mal ; second abdominal segment longest ; maxillary palpi 2-jointed ; mandibles arcuate, 

 slightly bidentate at apex.
