HYMENOPTEEOLOGICAL NOTES. 



BY P. CAMEROX, F.E.S. 



I.— ON SOME NEW OR LITTLE-KNOWN BEITISH HYMENOPTERA. 



Nematus oblongus, Cam. 



I believe tliis is N. Jar ids, Htg. The species varies not a little in 

 form and coloration ; and apparently, also, in the length of the an- 

 tenna). The form ollongiis has the body shorter and broader than any 

 of the continental specimens I have seen of laricis. I am not sure if 

 the (^ I have allotted to ohlongtis is really the (^ ; Zaddach is the only 

 author who describes the ^ of laricis. All that he says about it is 

 that the antennae are laterally compressed and yellowish-brown be- 

 neath, and that the stigma is yellowish-brown. 



The larva of N. laricis feeds on Abies larix. 



Nemattjs pallipes, Fallen, sec. Thorns. 

 = N. earinatus, Htg., sec. Zad. 



I am indebted to Mr. Gr. C. Champion for a specimen of this species 

 taken by him at Aviemore, Inverness-shire. It comes nearest to N. 

 astutus and N. lativentris, but differs from both in the legs and stigma 

 being yellowish-testaceous ; the hind femora are only slightly lined 

 with black, and, in particular, the middle lobe of the mesonotum is 

 U-shaped at the apex, not V-shaped as in the other species. AT. 

 hreadalhanensis, Cam., is a narrower species than it ; has the antennae 

 longer and thinner, the abdomen is longer, the femora and coxse are 

 broadly black, the rest of the legs whitish, not reddish-testaceous, the 

 spurs are shorter, and the transverse basal nervure is recurved nearer 

 the middle of the cellule. The keel on the mesonotum is indistinct, 

 and there is also an indistinct keel on the scutellum in my example of 

 palUpes. The third cubital cellule is longer and more dilated at the 

 apex than is astutus, and the wings are of a much more decided 

 fulvous tint. 



Nematus eagi, Zad. 

 Schr. Gres. Konig., xvi, p. 295, taf. 5, f. 1. 



On a beech hedge near my house here I found last July four 

 larvae of this species, and have succeeded in rearing three females from 

 them. The imago does not appear to be distinguishable with any 

 degree of certainty from N. croceus ; but, as the larvae are totally 

 different, there c^ii be no doubt of the two species being quite distinct.
