blotch, several smaller spots round the apical margin ; hind- 

 wings sub-hyaline, with a greyish tinge ; veins and pterostigma i 

 brownish. 



In general appearance the male is very similar to pale 

 examples of R. dorsalis, and the female still more so; indeed ,^ 

 had that species been present where they were taken, it would w- 

 have been scarcely possible to separate this sex of both i 

 species. The form of the appendages in the male, and 

 especially of the broad lobe from the last segment, will 

 readily distinguish it. There are several European species 

 very similar in general appearance, but most of these have 

 this lobe narrow and often acute at the apex. I 



Four examples, — two males and two females, — were taken 

 by Mr. Wormald near Llangollen, in September ; one of I 

 these he has with great kindness presented to me. 



Rlujacophila miinday M'Lachlan, Trans. Ent. Soc. Lon- 

 don, Ser. 3, Vol. L, Part 3, p. 309. (Frontispiece, iig. 6.) 

 A very prettj^ species. The anterior wings are pale golden- 

 brown, irrorated with cinereous, and with two transverse ' 

 cinereous bands ; the dorsal blotch extends to the base, and is 

 margined above by some black streaks. The lobe from the 

 last abdominal segment is very short and broad, the terminal 

 joint of the inferior appendages deeply cleft at the apex. 



In September, 1861, I met with this species at Shaugh 

 Bridge, near Bickleigh, Devon (junction of rivers Meavey 

 and Cad worthy), and again this year at the same place, and 

 also at Ivy Bridge and Cornwood. All my specimens are 

 males, unless the female be so like that of R. dorsalis that I 

 cannot separate them, but from the wide difference between 

 the males one would scarcely think this possible.
