Signiphora dipterophaga new species. 



$. Length, i.oo mm. In the table of species (Proc. U. S. National 

 Museum, 45, pp. 227 ff.) runs to the nigra group and in that runs to 

 nigra itself from which it differs in having the wings hyaline and the 

 body much more robust and the caudal wings broader. Differs from 

 hyulinipcnnis in being wholly dark metallic green except the tarsi, the 

 marginal fringes of the fore wing are considerably shorter (those at 

 apex being not quite a fourth of the greatest wing width), the pedicel 

 longer (2^2 times longer than wide), the club shorter. Middle femur 

 compressed, convexed ventrad (like a dilated scape) as in hyalinipcnuis 

 but here the middle tibial spur is black and barely longer than the stout 

 curved spine from the dorsal aspect of the middle tibia (between mid- 

 dle and knee), longer in the other species. Fore wing slightly yellow- 

 ish along the venation. Mandibles acutely bidentate. Caudal wings 

 three-fourths or more the width of the fore wings. Thorax finely 

 transversely lined, the abdomen scaly. Head lined like the thorax and 

 with a few pin punctures scattered. Pronotum large, half the length of 

 the scutum. Body glistening. Fore tibiae yellowish. 



Described from a large number of females reared from the 

 pupa of a dipteron collected on sugar cane in a tunnel of 

 Diatraea, Diego Martin, Trinidad, British West Indies, Jan- 

 uary, 1914 (F. W. Urich).

Coccophagus aleurodici new species. 



?. Length, i.oo mm. Habitus of the species usually referred to 

 l'ri>s/>altclla. Lustrous purplish black, the wings hyaline, the fore tihi.T 

 and tarsi dull yellow, funicle 3 dull white. Venation pale yellow. Club 

 as long as the funicle and distinctly wider; funicles i and 3 subequal, 

 each a third longer than wide; 2 twice longer than wide. Pedicel sub- 

 equal to funicle 2, the scape pallid, except the dusky dorsal ed.ye. Man- 

 dibles with the second tooth broadly truncate yet with its dorsal an.qlr 

 acute (so that there are apparently two small acute teeth and an innrr 

 truncation from the base of the second). Marginal vein somewhat 

 1'inuer than the submarginal, the stigmal oblique, of nearly uniform
