1908] GIRAULT — PECULIAR CASE OF PARASITISM 95 



ing the parapsides, mesoscutum, mesoscutellum, axillae, and lateral portions of the 

 mesopostscutellum), the dorsal aspect of the metathorax, the thoracic pleura (includ- 

 ing the femoral furrows, but excluding an irregular faintly lined area surrounding 

 the insertion of the wings in the direct lateral aspect) and the posterior coxae (but 

 distinctly less so) moderately roughly, nearly uniformly, punctately, sculptured into 

 polygonal areas, generally pentagons; this sculpture is from two to three times 

 rougher than the eye surface. Cephalic and intermediate coxae, sculptured nearly 

 similarly with finer lines; most of the thoracic ventum similarly sculptured (as the 

 cephalic coxae). Metathorax with a faint median carina. 



Abdomen shorter than head and thorax combined, normal for the genus, but 

 slightly triangularly produced ventro-proximad, and conic ovate; segment 2 the 

 longest, much longer than segment 3, the latter one-third longer than segment 4, 

 and the remaining subequal in length, excejjting the last; the forewings extend for 

 about one-sixth of their length beyond the abdomen. Body covered with moderately 

 sparse, grayish, inclined hairs, thicker on the coxae, legs, apical abdominal segments, 

 at the spiracles, and amounting to a soft, grayish pubescence on the antennae. 



Wings normal, hyaline; postmarginal vein about one-third longer than stigmal 

 vein, which is about one-fifth shorter than the marginal vein; stigmal knob ovate, 

 but with a nipple like prolongation at its apical third on the cephalic margin; sub- 

 marginal vein twice the length of the marginal. Discal cilia of the wings uniform, 

 close. Venation dusky. 



Antennae 13-jointed, with two ring-joints, scape and pedicel less hairy and sculp- 

 tured with very fine lines. Scape long and slender, projecting beyond the vertex 

 for at least a fifth of its length, at least more than half the length of the remaining 

 joints combined. Pedicel subconic, stouter, slightly more than half the length of 

 the first funicle joint; joints 1, 2, and 3 of funicle subequal, funicle joints 4 and 5 

 subequal, the former longer, one-fourth and one-third shorter than the 3 preceding 

 joints respectively; funicle 6 sub-quadrate, one-third shorter than the preceding 

 joint; club 3-jointed, the first two joints subequal, about equal in length to funicle 

 6 but narrower, and the third or apical joint nearly one-half shorter and conic; club 

 ovate in shape, longer than the combined length of the two apical funicle joints. 

 Both mandible 4-dentate, the dentations darker in color than the body of the man- 

 dible; the dentations are not symmetrical for both sides. Ovipositor not exserted. 



From 15 specimens; f-inch objective, Bausch & Lomb. 



Seen from the naked eye the species is very dark. 



Male: — The same. From the single specimen at hand, most of the antennae 

 are missing, but enough of the funicle is present to show that they are wholly fuscous,
