NEMATUS VACOINIELLUS. 191 



not reddish, and are more or less lined with black; 

 the upper median cellule is short compared to the 

 lower, the spurs are shorter, and it is also a smaller 

 and narrower species. It is more difficult to sepa- 

 rate from N. vacciniellus, but that has not the upper 

 middle cellule smaller than the lower ; the coloration of 

 the legs is different, it being not so white almost ful- 

 vous especially on the femora, which are not lined 

 with black; the apex of the abdomen (particularly 

 beneath and at the sides) and the belly in the centre 

 are brownish-testaceous, while in leucostigma they are 

 quite black ; the stigma is almost unicolorous, the hind 

 tarsi and apex of tibiae are not fuscous or black, and 

 the abdomen is longer compared to the head and 

 thorax ; the clypeus is black at the base, the part of 

 head above it being also black. 



The larva, according to Brischke, is bluish-green, 

 the last segments grey, with two short, fine, black 

 cerci, which are joined to a quadrangular black dotted 

 spot; the anal segment at the point is beset with 

 short hairs. Head shining reddish-brown and shortly 

 haired. The eye-spots black, the vertex is stained 

 with a broad dark spot, and between the eyes is a 

 transverse browner one. 'Mouth brown, claws clear 

 brown. 



When young the larva is yellowish. It lives in June 

 and July between the folded-down edges of the leaves 

 of Salix helix, feeding on the upper epidermis, thus 

 making brown spaces in the leaf. 



Not common. Braemar, Eannoch, Dumfriesshire.
