ART. U4. NEW REAEED PARASITIC HYMENOPTEEA — GAHAN. 19 



coloration, due to action of the preserving fluid in which they were 

 sent. The following description of the two sexes is drawn up from 

 the above-mentioned specimens from India, 



Female. — Pale yellowish, more or less tinged with fuscous, the 

 second to sixth dorsal abdominal segments bordered at apex with 

 brownish; antennal flagellum brownish. Head and thorax almost 

 sculptureless, the dorsum of latter very faintly lineolated; meso- 

 scutum with a delicate median groove ; propodeum short with a deli- 

 cate median carina ; abdomen ovate, a little longer than the head and 

 thorax; ovipositor slightly exserted. Antennae apparently with 

 four ring-joints; first funicle joint subequal in length to the pedicel; 

 about two and one-half times as long as broad ; second funicle joint 

 subequal to the first; third slightly shorter; club about as long as 

 two preceding funicle joints, 3-jointed, the apical joint small, indis- 

 tinctly separated from the preceding and terminating in a short spur. 

 Wings hyaline, the marginal vein distinctly longer than the submar- 

 ginal; postmarginal subobsolete; stigmal approximately one-third as 

 long as the marginal. 



Male. — Length 1.3 mm. Color and sculpture like that of female, 

 except that the apical half of abdomen is blackish. Abdomen small, 

 narrower and shorter than the thorax; antennae elongate slender; 

 scape on ventral margin near apex with a distinct ovate spot, prob- 

 ably a sensory gland, which is dark brown in color; pedicel obconical, 

 not twice as long as thick; three very minute ring-joints; funicle 

 joints four in number, each with a half whorl of very long hairs near 

 the base; first joint slightly longer than broad and slightly thicker 

 than the pedicel; second and third joints subequal, thickest at base, 

 each approximately two and one-half times as long as the thickest 

 portion is broad; fourth joint similar to the two preceding, but very 

 slightly shorter; club elongate, slender, a little longer than the two 

 preceding funicle joints combined, distinctly 3-jointed, the basal joint 

 with a whorl of hairs similar to that of the funicle joints; joints two 

 and three more or less hairy, but the hairs shorter and not arranged 

 in a distinct whorl; joints one and two subequal in length; apical 

 joint slightly shorter, conical and terminating in a short spine. 



Subfamily Elachertinae.

Euplectrus insuetus Gahan, Proc. U. S. Nat. Mns., vol. 48, 1914, p. 164. 



Mr. A. A. Girault * has correctly pointed out that this species does 

 not belong in Euplectrus where it was originally placed by the 

 writer. Girault, however, does not indicate where it should be 

 placed.
