Emphytus cinctus Linnaeus. European Rose Sawfly. 



This species feeds upon rose and raspberry in Europe, and 

 the larvse have been found many times in the pith of cut stems 

 of manetti rose stock imported into Connecticut from France 

 and England. It may become established in this country. 



The following description is copied from F. V. Theobald's 

 Insect Pests of Fruits, page 435 : 



" Adult 12 to 14 mm. General colour shiny black; head black, 

 with fuscous grey down ; palpi and labrum black* but the latter 

 may be pale grey, and also the apex of the former ; the nine- 

 jointed antennae are deep black. Thorax black, with two round 

 yellow to white spots, placed posteriorly. 



" Abdomen shiny black, a small but distinct pale blotch on 

 the middle of the posterior of the first segment ; the fifth seg- 

 ment has a dull white to bright white basal band spreading out 

 at the sides and passing ventrally; the apex is hairy, curved and 

 projecting. Legs, with the anterior aftd mid coxae and trochanters 

 black and testaceous; the hind coxae and trochanters yellowish- 

 white; the fore and mid femora are black, except at the apex 

 where they are testaceous or reddish, in the hind femora the base 

 is white ; tibiae and tarsi brick-dust red, but the tarsi show fuscous 

 shades, especially apically. 



" Wings hyaline, with a small pale basal spot ; costa reddish 

 brown to brown ; stigma black apically. 



" The male is much like the female, but has no pale area on 

 the fifth segment, the whole being shiny black; the antennae are 

 very similar but a trifle thicker; the hind femora are entirely 

 dark, and the palpi are quite white apically."
