EMPHTTUS GROSSULARI^E. 279 



Kaltenbacli lias described the larva). They feed in 

 shady places on Geranium robertianum. There are two 

 generations, the one in July, August and September 

 feeding on the radical leaves, the second in October 

 and November on the other leaves, which they eat to 

 the thick nerves ; they feed resting on the lower side. 

 The young larva is pale, dirty olive-green above, the 

 head blackish, the vertex and mouth paler or brown. 

 When fully grown they are 6 1'" in length, round, 

 slim, beset with a few white, small, pointed spines, 

 which are arranged crosswise on each segment, those 

 on the back being the most distinct. The head is 

 shining black, the vertex somewhat hairy, the oral 

 region brownish. The upper part of the body is olive- 

 green to greyish-black ; the underside, legs and the 

 lower half of the sides, whitish ; the three last abdo- 

 minal segments are mostly clearer, especially with 

 young specimens. 



Dours (Cat. Syn., p. 17) says that the larva feeds on 

 Sorlus aiicv^xt rut, on which plant the imago was taken 

 by Hartig. I have myself beaten the flies out of the 

 same plant, and also out of hawthorn in June. 



(.'tii^iiii is a common and generally distributed 

 Scotch insect. I have seen many English examples, 

 but do not know the precise localities. Norwich 

 (Bridgman). A Braemar specimen in my collection 

 has the tegulae black.

 France, Russia.
