358 Mr. R. Trimen's descriptions of new 



Teracolus, Swains. 

 Teracolus Bowkeri, n. s. 

 Allied to T. Agoye, Wallengr. 

 Exp. al. 1 in. 6 — 7j lin. 



$ . White, with yellow-ochreous apical patch in 

 fore wing. Fore wing : Base and costa sparsely irro- 

 rated with black ; apical patch internally irregularly 

 bordered with black, which is broad in its middle part 

 (and sometimes also in its upper part), but attenuated 

 and usually ill-defined towards its extremities ; a narrow 

 ray of clear yellow ochreous immediately beyond the 

 black, but the rest of apical patch tinged with greyish. 

 Hind wing : Base irrorated with black, more widely and 

 rather more closely than in fore wing ; a longitudinal 

 ray of black irroration on costa beyond middle, its outer 

 extremity sometimes strongly marked ; subcostal nervules 

 very rarely thinly defined with black ; in some specimens 

 a few black atoms scattered about disc. Under side : 

 Hind wing and apical area of fore wing very faintly 

 tinged with yellowish. Hind wing : Costa very narrowly 

 edged with chrome-yellow from base to a little beyond 

 middle ; a general very fine and very sparse irroration 

 of dusky atoms. 



? . Fore wing : Apical patch fuscous-brownish, 

 darker inwardly, traversed mesially by a dull yellow- 

 ochreous ray, which is sometimes suffused and ill- 

 defined ; base more widely irrorated than in male. Hind 

 wing : beyond middle, from costa, a transverse row of 

 three ill-defined dull-fuscous spots, the first of which 

 represents the termination of the black costal irroration 

 in the male. Under side : Yellowish colouring much 

 more decided than in male. Hind wing: Fine dusky 

 irroration closer than in male. 



This little species is to be distinguished from T. Agoye, 

 Wallengr., as far as the male is concerned, by (1) the 

 larger, paler, less warmly-tinted apical patch of fore 

 wing ; (2) total or almost total absence of black nervules 

 in both wings ; (3) want of copious black irroration in 

 fore wing ; and (4) presence of strongly-marked irroration 

 ray on costa of hind wing ; while (5) the under side is 

 somewhat more yellowish. The female has (6) a much 

 larger apical patch, owing to the breadth and extension 

 inferiorly of the fuscous-brown on its inner border ; but
