Nematus Fletcheri, Cam., E. M. M., July, 1884, p. 26. 



Black ; antennae brownish beneath, as long as the thorax and abdo- 

 men, tapering towards the apex ; tegulse, apex of coxae, trochanters, 

 base and apex of four anterior femora, extreme base and apex of 

 posterior, four anterior tibiae and tarsi, and posterior tibiae, except the 

 apex, white. Wings hyaline, costa fuscous, stigma blackish. Claws 

 with a sub-apical tooth. 



Length 2 2f lines. 



The $ I have not bred, but a caught specimen from 

 Thornhill must, I think, either belong to it or to nigri- 

 collis. It has the antennae as long as the body, the 

 third joint a little compressed, and they taper per- 

 ceptibly towards the apex. 



The larva feeds on hawthorn, eating the leaves along 

 the edge against which the body is closely pressed. It 

 is bright green, the anal segments red, the head 

 brownish. I was unable to make a minute description 

 of it owing to all the specimens I had spinning up. 



N. cratcegi, Zad. (Schr. Ges. Konig., xxiv, p. 147), 

 appears to be very closely allied to this species, but it 

 would seem to differ in having the labrum, mandibles, 

 and the edge of pronotum white, the antennae red, except 

 the basal two joints, which are black, and the apex of 

 the middle tarsi and the base of posterior are reddish- 

 yellow. 



The larva of cratcegi (which feeds on the hawthorn) is 

 green with a darker dorsal vessel, the head yellowish, 

 its vertex with a broad brown stripe, there being also 

 three stripes on the sides and face. The last segment 

 is rose red.
