194 Mr. P. Cameron's descriptions of new 



Vertex finely punctured, semiopaque, sutures distinct ; 

 antennal fovea large ; clypeus incised at the apex. Ovi- 

 positor short, not half the length of the abdomen ; sheath 

 almost glabrous ; apex acute, projecting more on upper 

 than on lower side ; tarsi shorter than tibiae ; spurs 

 almost straight, more than one-third of the length of 

 metatarsus. 



The male has the antennae longer and thinner, being 

 a little shorter than the thorax and abdomen : it is 

 almost glabrous. The stigma is fuscous, white at the 

 base. Length, nearly If lines. 



In most of the specimens the 3rd joint of the antennae 

 is longer than the 4th, but in one it is shorter. The 

 3rd cubital cellule is irregular in shape ; in some speci- 

 mens it is broader than long, in others slightly longer 

 than broad. The species has the greatest resemblance 

 to herbacea, but the darker- coloured stigma, much shorter 

 ovipositor, more acutely-pointed sheath (which is also 

 less hairy), and the femora more strongly marked with 

 black at the apex, readily enables it to be distinguished 

 from the alpine species. From N. crassispina it may be 

 known by the white mouth, longer tarsi and spurs (which 

 are almost straight), longer antennae, and by the stigma 

 not being unicolorous. 



Mr. J. B. Bridgman bred this species from oval green 

 galls found on sallows at Brundall, but unfortunately he 

 did not take a description of them nor of the larvae. No 

 doubt this omission will be rectified during the approach- 

 ing summer. 



Nematus Icetus, n. s. 



Black ; mouth and legs dirty white ; the coxae at base, 

 posterior and middle femora almost wholly above and 

 beneath, the anterior in the middle, the apex of posterior 

 tibiae and the tarsi, black ; tegulae black, the pronotum 

 close to them dull white. Wings hyaline ; nervures and 

 stigma dark fuscous, the costa paler. The body is broad, 

 and is covered closely with a short close pile ; the head 

 and thorax almost opaque, very finely punctured all 

 over. The vertex is thick, and has the sutures very in- 

 distinct ; the frontal area is not indicated. Clypeus 

 almost transverse at the apex. Antennae nearly as long 

 as the body, covered with a microscopic pile ; the 3rd joint 

 is longer than the 4th ; cenchri small. Abdomen not 

 much longer than the head and thorax together ; sheath
