CRCESITS VARUS. 43 



this splash is a small black dot ; the vertex is dotted 

 with minute fuscous points ; eye-spots black. The 

 legs are rather long, green, with brown claws, a some- 

 what triangular mark is over each ; the abdominal 

 legs are glassy green. The body is long and cylin- 

 drical, tapering towards the end ; the colour is bright 

 green ; the last segment is a little paler and bears a 

 black mark on the top. On the middle of the sides 

 is a row of black dots, placed rather wide apart and 

 ending on the twelfth segment. Below this row is 

 another line of smaller black dots, and directly over 

 each of the legs are two or three little black marks. 

 Near the head the superior row is placed higher up. 

 Length about 1213 lines. 



When young the larva has the ground colour pale 

 brown. 



It feeds on alder, and is less gregarious than that of 

 the other species of the group. Usually only one or two 

 feed on a single leaf; neither do they appear to be 

 so active as the more conspicuous larvas of septen- 

 trionalis and latipes. They are found from July to 

 September, and are double brooded. The images 

 first appear in June. 



Not uncommon in Britain. In Scotland I have 

 found it in Clydesdale, Glenelg, Kingussie, Braemar, 

 Rannoch. 



From England I have seen specimens from Wor- 

 cester (Fletcher), Devonshire (Parfitt), and Grlanville's 

 Wootton. 



It is widely distributed in Europe; Lapland, 

 Sweden, Finland, Riga, Prussia, Silesia, Harz Moun- 

 tains, Holland, and France. 



Kirby (List of Hym., i, 103) records it from Nova 

 Scotia.
