TENTH REDO VIRIDIS. 149 



brighter margined, appears darker. At the base of 

 the ventral legs is a brownish longitudinal streak, and 

 over the thoracic legs is a broader stripe ; the claws 

 of the latter are brown. Head reddish-brown, shortly 

 haired, shiny; eye-spots black; mandibles blackish. 



At the last moult the larva becomes smooth, shining, 

 yellowish-brown, the dorsal vessel bordered on each 

 side by a brownish line. On the sides are on each 

 segment many brown transverse streaks and points, 

 which often form oblique lines, running from the back 

 to the sides. 



He says it is found from August to October on 

 Salix caprea, Sorbus aucuparia, and Alntis incana. 



Tenthredo viridis (Vol. I, p. 97). 



The larvae are described by Brischke (1. c, 110, 

 pi. vii, fig. 7). He found them on Gircsea lutetiana, 

 Stellaria holostea, Ranunculus repens, Salix helix, S. 

 aurita, and Alnus incana. He says that the eggs are 

 placed in a sheath 10 mm. long, 1 J mm. broad, divided 

 into ten divisions, like the segments of a larva, in 

 each of which is an egg. The full-grown larva is 

 15 mm. in length, bright greenish-grey; the back to 

 the black stigmas somewhat darker, mottled with 

 brownish-black spots and points. The sides have 

 some dark spots, usually a larger spot under the 

 stigmas, and some small streaks and points upon the 

 side pads at the base of the feet. On each segment 

 are two transverse rows of white warts, between which 

 stand minute white points. Head covered with short 

 white hairs ; at the eye-spots is a black mark, and 

 there is a broader frontal spot between them. The 

 orbital sutures suffused with reddish-brown. Antennas 

 moderately long. At the last moult the larva is 

 smooth, without warts, transversely wrinkled and 

 brick-red, and having on the back some transverse 

 streaks. On the head only the eye-spots are black.
