BLENNOCAMPA GENIOULATA. 239 



The has the antenna) nearly as long as the body, thicker and more 

 compressed than in the ? , and the knees are black. 

 Length 2f lines. 



This species may be known from fuliginosa (its 

 nearest ally) by its longer antennae, interstitial tr. 

 radial nervure and clearly white knees. 



The larva I find on Spi/rc&a nimaria in June and 

 July, while it feeds also on Geum urbanum, Rubus 

 ccesius and durnetomiu, according to Kaltenbach. The 

 head is shining, faintly pilose, greenish-yellow, the 

 yellowish tinge being more intense on the vertex ; the 

 eye spots are black and the mouth brownish. The 

 body is dark green, the dorsal canal somewhat darker. 

 On each segment are two rows of double forked 

 spines, one being placed somewhat in front of the other. 

 The spines over the anal segment and also those over 

 the legs are single, while those on the second segment 

 are four-spined. The legs are glassy, yellowish-green, 

 claws brown. Length 5 6 lines. It rests on the 

 underside of the leaves, eating irregular holes and not 

 unfrequently reducing them to a skeleton. It pupates 

 in the earth, and does not appear in the perfect state 

 till the following spring or early summer. At the last 

 moult the spines are cast off, and it becomes of a 

 uniform green colour. 



A common species in early summer in Scotland. Mr. 

 Fletcher takes it at Worcester. 



Continental distribution : Sweden, Germany, France, 

 Tyrol, Hungary, Russia.
