1916] GirauU — New EncyrtidcE from North America 49 



Paracopidosomopsis Gen. nov. (Encyrtini). 



Female: The same as Berecyntus Howard but the mandibular 

 teeth are small and subequal. Type: B. floridanus Ashm. 



This species is closely allied with the so-called Copidosoma 

 truncatellum Dalman (at least specimens from Europe in the U. S. 

 National Museum, so labelled) which is congeneric, but the Amer- 

 ican species differs in having a distinct, rectangular fuscous patch 

 against the stigmal and marginal veins with a more suffused area 

 caudad of it, while in the European species the wings are hyaline. 

 Otherwise the two are certainly much alike! Mr. A. B. Gahan 

 has identified a series oi floridanus as truncatellum but for the present 

 I do not think the two can be regarded as the same. These speci- 

 mens were labelled "Laf. 11. Lafayette, Ind., J. J. D. Reared 

 from cabbage Plusia larva." 



Berecyntus Howard. 



In my table of genera runs to Copidosomopsis Girault but differs 

 in the following essentials : The marginal vein is somewhat longer 

 than wide, the postmarginal distinct, about half the length of the 

 marginal, the abdomen is broader, flat and subcordate, the stigmal 

 vein is slightly longer than the marginal. Axillee rather broadly 

 joined. Mandible with the third tooth minute, the first long, over 

 twice the length of the second which is over four times the size of 

 the third. Ring joint very minute. Club solid, obliquely trun- 

 cate. Hind tibial spur single, the middle one enlarged. Genal 

 suture absent. Scrobes not reaching to the middle of the face yet 

 distinct, of tolerable length, forming an inverted "V." Club wider 

 than the funicle and about three fourths its leogth. 



Berecyntus bakeri Howard, var. gemma, var. nov. 



Female: Length, 1.15 mm. Metallic blue-green, the middle 

 knees and all tarsi except the distal joint, reddish-brown, the vena- 

 tion blackish, the fore wings lightly infuscated from the head of 

 the submarginal vein distad to the apex. Funicle joints increasing 

 gradually in width distad, 1 quadrate not half the length of the 

 pedicel, subequal to 2, 6 somewhat wider than long. Pedicel dis- 

 tinctly longer than wide at apex, nearly half the length of the club 

 which is a little shorter than the body of the scape. Hind wings
