192 NEMATUS OBLONGUS. 



little wider than long; the second transverse cubital nervure received 

 about its own length in front of, the transverse basal nervure received 

 a little in front of the middle of the cellule; the second cubital cellule 

 has a horny point. $. 



The ? , according to Zaddach, has the antennae black, the coxae only- 

 black at the base, and the femora are less strongly marked with black. 



Length 7 mm. 



The femora want the reddish tinge so conspicuous 

 in the femora of a/ppendiculatus ; the vertex and front 

 are much more strongly punctured, as is also the 

 mesonotum; the hind tarsi are entirely black, and 

 the apex of the hind tibiae is more distinctly and uni- 

 formly so ; the third cubital cellule is shorter, and 

 is not dilated at the apex, and the pubescence is 

 darker. 



The larva feeds on Larix in August. It is 10 mm. 

 long, green, the dorsal vessel darker and bordered 

 with white ; over the legs is a white longitudinal line ; 

 the head shining, the eye-spots black. 



Brischke says there-are two generations in the year.

Nematus oblongus (Vol. II, p. 69). 



In E. M. M., xxiii, 193, I have suggested that this 

 may be identical with N. laricis, Htg. On re-exami- 

 nation I am inclined to doubt this ; in fact, from the 

 obsolete pentagonal area, and from the shorter body 

 form, I should be inclined to refer oblongus to Pristi- 

 jphora rather than to Lygsenematiis, to which group 

 Konow refers laricis. The first transverse cubital 

 nervure is quite distinct.
