NOTES ON BEITISII TENTHREDINIDM AND CYNIPIDJE. 

 BY P. CAMERON. 



Having this year had an opportunity of examining the Tcnthre- 

 dinidce in Stephens' Collection, I give here a few of the most important 

 notes which I made on the specimens. It would serve no useful 

 purpose to mention all the misnamed species which I noticed, as in 

 many cases four or five species, belonging to nearly as many different 

 genera, are under one name, and frequently these bear no resemblance 

 to the description of the species they are supposed to represent. 



Hylofoma Leachi, 111. Mand. vii, p. 17 = ustulata. H. anglica, 

 p. 16 = herheridis. 



Lojihyrus jyall/dics, p. 21 ==, I believe, rufus. Pallidus must, 

 therefore, be deleted from our lists, as I know of no British 

 specimens. 



Prist opliora varipes, p. 27 = Cladius padi and C. difformis. 

 P. atra^ p. 26 = G. padi. P. duplex^ p. 26 = 1 JSfematus conductus, 

 Euthe, and 1 N. ohduetus, H. P. rufipcs, p. 26 = apparently 

 N. compressicornis, Fab. ( = ? ahiivonis, Cam.), or a large specimen 

 of N. fulvipes, Fall. P. festaceicornis, p. 26 = riijicornis, 01. 

 P. pnllipes, p. 25 = iV". appendicidatus, H. P. testacea, p. 25 ^ 

 1 N. palJidioentris, Fall., and 1 N. ribesii, Scop. 



Euura cynips (of the collection, but whether of Newman is 

 another matter) ^ 3 iV. Vallisnieri and Euura gallw. E. gallce 

 = ? a new species. 



Black, shining : moutli, tegiilee, feet, and pronotum white : head a little testa- 

 ceous behind the eyes : femora nearly all black, with a pale band on the under-sido 

 of posterior : posterior tarsi and apex of tibifc broadly black : posterior tarsi nearly 

 longer than tibiae : antennee nearly as long as the body, thin, 3rd and 4th joints 

 equal : cenchri large, dull white : cerci long, slender, pale, pointing outwardly : 

 terebra long, hairy, projecting : area pentagona very distinct : wings hyaline : stigma 

 white, fuscous at base : 3rd sub-marginal cellule nearly square : Ist sub-marginal 

 nervure distinct. 



Comes near N. doUchurus, Th., but the coxae and trochanters 

 arc pale, and the apex of the tibiae and posterior tarsi are black. The 

 antennae are longer and thinner than in JSf. cinerece, the area pentagona 

 much more distinct, the band on the pronotum more conspicuous, and 

 at the same time shorter and thicker. 



Should this species prove (as I suspect it will) to be undescribed, 

 I propose for it the name of Nematus anglicus. 



Nematus bicolor, p. 27 = Dineura stilata. N. gallicola, p. 36 = 

 N. Vallisnieri and a Onjptocampus. JV. proximus, p. 36 = 1
