534 RED U VINA. 



abruptly beyond the middle, subsiding into gray, and is previously 

 crossed by a brown shade ; exterior to the 1st nerve, and close to 

 the posterior margin, is a round, conspicuous, white spot ; on the 

 disk 2 large, indistinct, gray spots, one in the middle, the other 

 joining the end of the clavus ; claval suture narrowly black; Mem- 

 brane brownish-yellow, with darker shades, nerves piceous ; at the 

 exterior basal angle a large, angulated, yellow spot, followed, on the 

 margin, at the end of the 1 st nerve, by a blackish spot ; the rest of 

 the margin brown, but inwardly often a clearer long streak. Legs 

 pale yellowish-brown ; tibice at the apex narrowly black ; tarsi ; last 

 joint piceous. 



Abdomen beneath, with fine yellow pubescence. 



Length, 1| If line. 



Scarce. Beigatc Heath, and near Hammersmith Bridge, in 

 March (Dr. Power). 



Two specimens taken by Dr. Power have the 2nd joint of the 

 antenna black, as in S. cincta, and in one of the specimens the last 

 joint is light brown, in all other respects they agree with 8. 

 elegantula. Plor, indeed, gives S. elegantula as a form of 8. cincta 

 with undeveloped wings, but this is not the case in our specimens ; 

 and although the two species are much alike, yet, besides the normal 

 differences in the colouring of the antennae and elytra, there are the 

 erect black hairs on the corium of S. elegantula, which are entirely 

 wanting in 8. cincta ; we cannot, therefore, accept their identity as 

 proved.
