the legs, black tarsi, and generally more deeply coloured 

 costa and stigma. From Ginereipes it is known by 

 its longer and less oblong body, lighter coloured tibiae, 

 clearer wings, interstitial tr. radial nervure, and more 

 projecting saw. 



In some males the tibiae are nearly quite black. 



A very commonly distributed species, appearing in 

 May among herbage. 



On the Continent it has been recorded from Prussia, 

 and I have seen French examples.

Black, shining; knees, tibiae and tarsi yellowish-white; the apex of 

 posterior tibia) and tarsi fuscous ; tegulae black ; antenna) a little 

 longer than the abdomen, the joints distinctly separated ; the third 

 nearly as long as the fourth ; the two basal joints large, the first 

 oval, the second cylindrical ; clypeus truncated at apex. Wings fuscous, 

 almost iridescent; the tr. radial nervure is received immediately in 

 front of third tr. cubital, being almost interstitial ; stigma large, black ; 

 costa black. The terebra projects largely, the apex is sub- acuminate.

Length 2 2 lines. 



The larva lives in rolled down leaves of Rosa canina, 

 the rolling down of the two sides of the leaf being 

 done by itself, but aided by the incision made by the 

 ? when laying the eggs, the whole leaf being thereby 

 deformed and converted into a complete cylinder, under 

 the cover of which it lives, but not permanently, as it 

 changes its abode when it no longer affords it nourish- 

 ment. In this way I have seen the foliage of whole 

 bushes distorted and the vitality of the plant impaired. 



The larva is somewhat short and stumpy. Its head 

 is narrower than the second segment, smooth, shining,
