the hind segments, thus differing from most of the 

 leaf-rolling larvae. The head is small and shining, 

 clouded with grey, vertex black. 



This species was discovered hy Mr. J. E. Fletcher 

 near Worcester.

Black, almost shining ; antennae about a fourth shorter than the 

 body, black, filiform, the third and fourth joints about equal, the rest 

 becoming gradually shorter, and more distinctly separated, and trun- 

 cated at the apex. Head black; labrum and clypeus white, pilose, 

 clypeus incised ; mandibles piceous at the tips ; palpi fuscous ; vertex 

 finely punctured and covered with depressed pile. Mesonotum semi- 

 opaque, finely punctured (more distinctly than the vertex) ; scutellum 



hining, almost impunctate ; cenchri obscure ; pleura smooth, shining ; 

 the edge of the pronotum and the cenchri white. Abdomen a little 

 longer than the head and thorax, the apex bluntly pointed ; cerci very 

 long, pointing outwardly, saw projecting beyond the cerci, pilose. Legs 

 white ; the extreme base of coxae, the femora, except at base and apex, 

 the apex of the posterior tibia3 and tarsi, the extreme apex of the 

 anterior tibiae, and the apex of the tarsi, fuscous ; calcaria short. Wings 

 hyaline; costa fuscous ; stigma large, fuscous at the base, white at the 

 apex ; the third cubital cellule is longer than broad ; the second recur- 

 rent nervure is received considerably in front of the second cubital. 



The (^ is similar in coloration, the antennae are a little longer, but 

 not much thicker ; the underside fuscous, and the third joint shorter 

 than fourth ; the stigma fuscous. 



Length 2 2 lines. 



This species comes near, in its general coloration, 

 to N. ischnocerus, but it is larger and broader, the 

 antennae are stouter, the femora and tarsi are almost 

 entirely black, the white at the base of the legs is 

 much clearer and the stigma is fuscous, with the base 

 white, the opposite being the case with N. ischnocerus ; 

 the $ has the stigma entirely fuscous, while in the 

 latter it does not differ much from the ? . 



The larva lives in the rolled-down leaves of the osier 

 (Salix vitellina), and in coloration, as well as in habits, 

 it agrees closely with N. leucosticMs, The body is
