This species resembles in nearly all respects sulcata so very much 

 that it is not necessary to give any description ; the distinguishing 

 character, and, so far as I see, the only real difference lies in the 

 colour of the wings; these have at the posterior margin, about from 

 the axillary angle to the apex of the postical vein or somewhat 

 beyond this, a distinct, blackish border, which vanishes evenly in- 

 wards. Though this is a small difference, the border is, hovvever, 

 rather characteristic, and I think the species is qiiite certain. Schiner 

 says, that the hind legs are not sulcated, but this is not correct, the 

 hind legs may be sulcated or not, quite as in sulcata. 



Length 6—7 mm. 



Rh. cinerascens is very rare in Denmark, only two specimens, both 

 females, have been taken in 1909 and 1910, one at Allerup near 

 Esbjerg and one at Silkeborg (Esben Petersen); the dates are •''/■.— ^/n, 

 the species is thus a spring species. 



Geographical distribution : — Northern and middle Europe down 

 into Germany; it is not known north of Denmark.
