228 ERIOOAMPA TESTACEIPES. 



The eggs are laid in the midrib in May, the larvse 

 appearing in early summer. The small oval cocoons 

 are spun in the earth. A second brood appears in 

 France during September and October, there being also 

 two broods in America, where it is very destructive to 

 garden roses. 



Common in gardens in England and Scotland. I 

 suspect it has been introduced into America from 

 Europe, like the gooseberry grub Nematus ribesii. 



Continental distribution : Sweden, Holland, France, 

 Germany. 



0& s< This common species agrees tolerably well with the description 

 of Tenthredo aethiops, Fab., E. S., ii, 121, 65; S. P., 39, 49, which 

 was described from an insect in the Banksian Collection; but the 

 typical specimen (from England) has been either lost or destroyed. In 

 Europe it was first described by Westwood, who referred it to the 

 aethiops, Fab., but long before that it had been described in America by 

 Harris under the appropriate name of rosce ; I certainly think the 

 Harrisian name should be adopted, because there is no dispute about it, 

 while the Fabrician description is by no means clear, and the name has 

 been applied to other species. The late Prof. Zaddach informed me 

 that aethiops in the Fabrician Collection in Kiel is represented by a 

 Blennocampa. The aethiops of King and Hartig may possibly be the 

 aethiops mentioned by Zaddach. It is regarded by Thomson (Hym. 

 Sc., i, 213) as a variety of Blennocampa eppiphium, Pz., with the thorax 

 entirely black, but on the other hand, Gorski says that King's type of 

 aethiops in the Berlin Museum is identical with E. 'limacina, save that 

 it has only one middle cellule in hind wings, and limacina certainly has 

 sometimes only one cellule. I have received a " Blennocampa aetliiops " 

 from several Continental entomologists, but it proved always to be B.

Black, shining; coxse, trochanters and basal three- fourths of femora 

 black, the apical fourth, tibia? and tarsi yellowish-testaceous; apex of 

 hinder tarsi fuscous. Wings slightly longer and narrower than usual, 

 smoky; costa and stigma black; transverse radial nervure received 

 nearly in the middle of the cellule, straight, scarcely oblique. J". 



Length 2 lines ; alar exp. 5 lines. 



Differs from roscv in having the wings somewhat 

 longer and narrower, the third cubital cellule is longer, 

 being distinctly longer than the second, which is
