1908] GIRAULT — PECULIAR CASE OF PARASITISM 93 



the head, meso- and metathorax with a greenish hue; abdomen with purpHsh hues; 

 eyes and ocelU dark garnet; the distance between the lateral ocelli and the margin 

 of the eyes is not so great as the distance between these ocelli, but much greater than 

 that between each lateral ocellus and the cephalic ocellus; epicranial lobes convex. 

 Scape and most of the pedicel, and the legs, excepting the coxae, fuscous. Coxae 

 and remainder of antennae blue-black. Eyes with sparse minute hairs, practically 

 naked. 



Head and thorax, including the metathorax and axillae, moderately pentagonally 

 punctate, the abdomen apparently smooth, but in reality similarly sculptured with 

 fine shallow lines like net-work. The sculpture of the head and thorax slightly 

 coarser than the surface of the eye. Pleura and coxae less deeply sculptured. 



Wings normal, the submarginal vein much longer than the marginal, and the 

 stigmal vein curved, its club with a prolongation at the cephalic extremity. Discal 

 cilia moderately dense and uniform, and a large dusky cloud under the marginal 

 vein extending along and beyond the stigmal vein to the apical fourth of the wing, 

 and across nearly to the opposite (caudal) margin where, however, it is limited by a 

 distinct angular milky-white line which starts in the apical fourth of the wing, curves 

 slightly convexly, and then obliques down (caudad) and in (proximad) toward the 

 caudal margin of the wing, nearly reaching that margin at a point about opposite 

 the middle of the marginal vein, and sharply cur\ang upward (cephalad) and inward 

 (proximad) toward the submarginal vein limiting the proximal spread of the dusky 

 area; this line is not devoid of discal cilia. Under the microscope, the dusky area is 

 also seen to extend through the angle subtended by the stigmal vein and the post- 

 marginal vein and to the caudal margin, beyond the whitish line, in fact faintly suf- 

 fused over the apical fourth of the wing. Sheaths of the ovipositor barely exserted. 



Scape of antennae slender^ uniformly cylindrical, about as long as the pedicel 



and the first three funicle joints combined; pedicel as long as the first two funicle 



oints combined, subclavate; first funicle joint shorter and narrower than funicle 



oints 2, 3, 4, 5, 6 and 7, which are uniform, subquadrate and subequal; 2 basal club 



oints very slightly larger than the apical funicle joint, subequal; the third or apical 



club joint nearly a half smaller and conical. Antennae uniformly hairy, less thickly 



so on scape and pedicel. 



From many specimens. §-inch objective. Bausch & Lomb. Coddington lens, 

 ^-inch. 



Male: — The same, but more slender. Antennae subclavate, more hairy, the 

 joints more distinct, the funicle joints widely separated ; the scape and pedicel dark, 

 funicle and club fulvous. Scape as long as pedicel and first 4 funicle joints combined.
