354 Mr. R. Trimen's descriptions of new 



2 . Rather paler and slightly more ochraceous. 

 Fore wing : Discal pale space less obscure, not radiating 

 on median nervules, but extending more or less distinctly 

 beyond discal row of spots. Hind wing : Spots not 

 quite so indistinct. Under side : Hind wing and apex 

 of fore wing less hoary, more brownish grey. Hind 

 wing : Spots of basal area, except first and last of outer 

 row, altogether obsolete ; sagittiform spots of sub- 

 marginal row much larger and more distinct. 



The absence of yellow-ochreous colouring at once dis- 

 tinguishes this very dingy Arrugia from A. Protumnus 

 Linn., and makes it more like A. basuta, Wallengr., 

 which is the type of the genus. 



From the latter, as far as the male is concerned, A. 

 brachycera may be known by (1) its darker colouring, 

 (2) larger and more pronounced spots, and (3) want of 

 whitish on disc ; while on the under side (4) it is con- 

 siderably darker, (5) has the fore-wing spots much 

 larger (with the marked exception of the spot near base 

 below cell), and (6) the discal row of hind wing much 

 broader and more regular. The female is readily recog- 

 nised by (7) wanting the conspicuous white discal mark- 

 ings of the female A. basuta on the upper side. Apart 

 from pattern and colouring, the remarkable shortness of 

 the antennae is very noticeable, especially in the female, 

 where they are only about 2£ lines in length, — shorter 

 than in Protumnus, and much shorter than in A. basuta. 



This Arrugia, which I formerly regarded as a local 

 race of Protumnus (see Rhop. Afr. Aust., ii., p. 279, 

 obs.), is rare in collections. I found it in some abundance 

 at Kuysna, on the south coast of the Cape Colony ; and 

 a few examples of what I consider a small dark variety 

 of it have been taken at Cape Town. It appears in the 

 height of summer, and delights to sit on the ground in 

 the hottest and dustiest places.
