152 PROF. E. B. POULTON ON 



concolorons, in strongly marked specimens with dark oclireons 

 or even fuscous-mixed dots. Hind wing with termen smooth; 

 concolorous with fore wing, discal dot and postmedian row of 

 dots present, the latter followed by a not very strong band of 

 ochreous shading. Under surface glossy, slightly less pale 

 ochreous (especially the fore wing), without markings. 



1908 : Mar. 24,-1 ? ; Aug. 15,-1 2 ; Sept. 26,-1 $ . 1909: 

 Jan. 14,-1 2; Jan. 20,-1 $; Apr. 16,-1 5 ; Apr. 20,-1 $; 

 May 8,-1 2 ; Oct. 7,-1 $ (type). 1910 : Jan. 8,-1 $ . 



Apart from the colour, and the presence of dark cloudings 

 distally to the postmedian line, this neat little species differs from 

 heckeraria in having the termen of the fore wing, on an average, 

 less oblique. 



ACIDALIA PYRRHOCHRA, Sp. n. (PL II. fig. 18, $ .) 



$ , 23-25 mm. Structure of the preceding. Face blackish 

 fuscous (in all three examples badly abraded below). Shape and 

 essential markings of timia, of which it might possibly be an 

 extraordinarily dijSerent colour-form, unconnected with the name- 

 type by any transitions. Strongly rufous ochreous, as in ftdvi- 

 color Hmpsn. (Nat. Hist. Socotra, p. 331), or the most rufous 

 aberration of nephelojyeras Prout, in two of the examples finely 

 irrorated with blackish, in the other more uiiiform ; in place of 

 the two ochreous patches which characterize ti'inia there is a 

 continuous black-grey clouding proximally to the dentate sub- 

 terminal line (which is, in consequence, distinctly expressed), 

 and some slighter shading distally to the same — altogether re- 

 calling certain forms of marginepunctata Goeze, neplieloperas 

 Prout, etc., more than iimia. Under surface rather paler than 

 upper, the distal cloudings faintly indicated in gi-eyish. 



1908: Oct. 30,-1 ? (type). 1909: Apr. 9,-1 $; Nov. 16, 

 1 S. 



The last-mentioned (the example without blackish irroration) 

 is further aberrant in having the distal cloudings extremely 

 weak, the discal dot of the fore wing surrounded by an ill-defined 

 deeper reddish spot, that of the hind wing very minute. Easily 

 distinguished from the reddest form of neplieloperas by the 

 absence of black terminal line and triangular subapical dot, etc.
