534 Mr. P. Cameron's descriptions of ten new 



joint shorter than the 4th, but longer than the long 

 diameter of the eye ; the four basal joints are black 

 above. The 3rd cubital cellule is nearly one-fourth 

 shorter than the 2nd ; the recurrent nervure is received 

 close to the 2nd transverse cubital. The spurs reach to 

 near the middle of the metatarsus, and are nearly as 

 long as the cerci. Extreme apex of sheath black. 

 Length, 2| lines. 



Belongs to the luteus group. It differs from N. hi- 

 lincatus in its longer and clearer coloured antennae, less 

 sharply incised clypeus, in the lighter tint of the bodj^ 

 coloration, narrower head and abdomen, longer spurs, 

 clearer and more yellowish wings, longer 3rd cubital 

 cellule ; by the narrower black bands on mesonotum and 

 on breast, where the black is much narrower, and by the 

 black marks on the abdomen. In the last peculiarity it 

 approaches N. acmninatiis, Thoms., as it does in body 

 form, but the apex of the abdomen is broader, the body 

 stouter, broader, the mouth and tibiae are not white, the 

 2nd and 3rd cubital cellules are longer, the recurrent 

 nervures received nearer the transverse cubital, and the 

 recurrent nervure in hinder wings is not interstitial.

Nematiis collinus, n. s. 



Luteous ; the head (mouth excepted), antennae, the 

 breast, metapleura more or less, three longitudinal marks 

 on mesonotum, scutellum, metanotum in centre, apex of 

 posterior tibiae and tarsi, black ; apex of clypeus, labrum, 

 coxae, trochanters, tibiae, and greater part of four ante- 

 rior metatarsi, white. Wings hyaline ; costa testaceous 

 at base ; apex fuscous ; stigma black ; 3rd cubital cellule 

 much longer than broad, and much wider at apex than 

 at base ; recurrent nervures in hind wings received close 

 to each other. Antennae shorter than thorax, and abdo- 

 men stout, tapering at apex ; the 3rd joint shorter than 

 4th. Clypeus slightly and broadly incised. Spurs more 

 than one-third of the length of metatarsus, and a little 

 longer than the cerci. Sheath of saw black at apex. 

 Length, 3^ — 3f lines. 



Similar to melanocephalus, but smaller. Antennas, if 

 anything, longer ; the mesonotum not entirely black ; 

 3rd cubital cellule much longer and narrower at base 

 compared to width at apex ; spurs a little longer and
