202 NEMATUS GALL1COLA. 



102. NEMATUS CURTICOKNIS, sp. nov. 

 PI. XXVI, fig. 6, Saw. 



Black, pilose ; eyes broadly bordered (especially behind) with, brown ; 

 mouth, tegulse, and pronotum broadly white ; ventral surface and apex 

 of abdomen and cerci pale testaceous ; legs whitish, femora testaceous, 

 bordered above and beneath with black, apical joints of tarsi fuscous- 

 black. Spurs short, thick, not one-third of the length of metatarsus ; 

 clypeus deeply incised. Antennae about the length of the abdomen, 

 stout, slightly compressed, pilose, third joint a little longer than fourth, 

 the apical joints brownish beneath. Wings hyaline, costa pallid tes- 

 taceous, stigma fuscous, white at the base ; first transverse cubital 

 nervure pale, semi-obsolete ; third cellule a little longer than broad, 

 wider at apex than at base, second recurrent nervure received a little in 

 front of second transverse cubital ; recurrent nervure in hind wings 

 almost interstitial. Front projecting, sutures on vertex deep, penta- 

 gonal area not very clearly defined. 



Length nearly 3 lines. 



It is not very easy to distinguish this species from 

 N. salicis-cinerece. The antennae are shorter and 

 thicker, the body is broader, stouter, and more pilose ; 

 the colour of the tibise is a purer white without any 

 trace of testaceous, and the saw is different in shape, 

 as will be seen by a reference to the figures. 



Rannoch, in June on willows.
