208 NEMATUS BEIDGMAN1I. 



white; cerci long, slender, pale, pointing outwardly; terebra long, 

 hairy, projecting; pentagonal area very distinct. Wings hyaline; 

 stigma white, fuscous at base ; third cubital cellule nearly square ; first 

 transverse cubital nervure distinct. 

 Length 2 lines. 



The antennae are longer and thinner than in N. salicis- 

 cinerecB, the pentagonal area more distinct, the white 

 band on pronotum more conspicuous, and at the same 

 time shorter and thicker. I adopt the name of 

 " alienatus " from Mr. Kirby's determination. The 

 species is in Stephens' collection under the name of 

 " Euura gallce"

Nematus Bridgmanii, Cam., Trans. Ent. Soc., 1883, p. 193. 



Black, shining, shortly pilose ; labrum, clypeus, tegula3, apex of coxae, 

 trochanters in front, more or less of femora, tibiee and tarsi, white ; 

 basal three-fourths of anterior femora broadly lined with black, poste- 

 rior almost wholly black ; apex of posterior tibia3 and tarsi faintly fus- 

 cous. Wings hyaline, costa and stigma pallid fuscous, extreme base of 

 latter white Antennae a little longer than abdomen, moderately stout, 

 tapering slightly towards the apex, covered with microscopic pile; 

 vertex finely punctured, semi-opaque, sutures distinct ; antennal fovea 

 large, clypeus incised at the apex ; ovipositor short, not half the length 

 of abdomen, sheath almost glabrous, apex acute, projecting more on 

 upper than on lower side ; tarsi shorter than tibiae ; spurs almost 

 straight, more than one-third of the length of metatarsus. 



The $ has the antennae longer and thinner, being a little shorter 

 than the thorax and abdomen; it is almost glabrous ; stigma fuscous, 

 white at base. 



Length nearly If lines. 



In most of the specimens the third joint of the 

 antenna? is longer than the fourth, but in one it is 

 shorter. The third cubital cellule is irregular in 

 shape ; in some specimens it is broader than long, in 

 others slightly longer than broad. The species has 

 the greatest resemblance to N. herbacece, but the 

 darker coloured stigma, much longer ovipositor, more 

 acutely pointed sheath (which is also less hairy), and 

 the femora more strongly marked with black at the
