200 GEOMETRID MOTHS 



prominently; cell-mark better developed, rather elongate; 

 postmedian rather less incurved behind M~, the thick ochreous- 

 brown line distally to it better developed. Hind wing similarly 

 with the markings well expressed ; antemedian line rather 

 sharp; cell-mark conspicuous. Underside almost entirely 

 unmarked. 



Mt. Poi, 4350-4500 feet — 1 c/, type and another cf . 



Also known to me from Ivedah Peak, Malay Peninsula. 



101. ECTROPIS (RUTTEl.ERONA) LITHINA Warr. 



Paralcis lithina Warr., Nov. ZooL, x, p. 398, 1903, British New Guinea. 



Mt. Poi. 4350 feet— 1 cf . 



As the Borneo subspecies is at present ""in the press" and 

 will appear shortly in the "'Novitates Zoologicae" I will not 

 complicate the bibliographer's work by referring to it by 

 name here. 



102. ECTROPIS TRTSTIS Butl. 



Abaciscus tristis Butl.. 111. Het., vii. p. 102. pi. cixxv, f. 18, 188«, 

 N.W. India. 



Mt. Poi, 4350 feet— 1 cf • 



An aberration witli the white markings reduced. The forms 

 from X.W. India and Assam (whence alone I have hitherto 

 known it) show this to be a variable species. 



103. EcTROPis PICTA Warr. 



Myrioblephara picta Warr., Nov. ZooL, iii, p. 404, 1896, Java. 



Mt. Poi, 4350-4500 feet— 29. 



Both appear more heavily marked — especially in respect of 

 the distal area of hind wing above and beneath — than Warren's 

 Javan type. Perhaps racial. 



104. Cleg p. A determinata Walk. 



Boarmia determinata Walk., List Lep. Ins., xxi, p. 384, 1860, 

 Sarawak. 



Mt. Poi, 4300-5000 feet— 5 d*. 



Inhabits the Malay Peninsula, Sumatra, and Borneo. I 

 formerly considered Walker's suggestion that this might be a 

 subspecies of the Indian alienaria Walk, to be well founded, 

 but as I have recently discovered that there are other claimants 

 in Malaya, which I have not yet fully worked out, I continue 

 to quote determinata as a species.
