ISTG 1 101 



femora for the greater part bluek ; posterior tarsi black ; and the abdomen above is 

 brownish at tlie junction of the segments. The head is quite black, with the mouth 

 obscure testaceous. 



This iusect was bred by Mi*. C. Ileuly (to wlioni I aui indebted 

 for specimeus) from galls on Vaccinium ritis-khea, found by Mr. 

 Eedle in Scotland ; and has been referred by INIr. Newman to liis 

 Eintm gallce. Mr. Newman, of course, ouglit to be well acquainted 

 with his own species ; but, so far as his description goes, it is not 

 detailed enough to enable this, or indeed any species, to be identified 

 with it, at least with any certainty ; and it therefore must be entirely 

 ignored. It agrees tolerably well with Thomson's description of cras- 

 sipes, except that his species has not the eyes surrounded with luteous, 

 and no mention is made of the pronotum being white. Crassipes was 

 split off by Thomsom from the N. helicinus of Brischke ; and he quotes 

 Brischke's account of the gall-making habits of his species for cras- 

 sipes, and not for helicinus, although that is also described. If crassipes 

 has actually been bred from willow-galls on Salix helix, then I think 

 it highly probable that the Scotch insect is distinct ; but, in the absence 

 of types, and of definite information regarding the early stages of 

 crassipes, I think it safest in the meantime to consider it as a variety 

 only. Should it ultimately prove to be distinct, I propose the name 

 of vacciniellus for it. 



I may add that neither Thomson's description of helicinus nor 

 of crassipes agrees with a specimen of helicinus = vesicator, Bremi, 

 which I received from Herr Brischke.
