48 CTMATOPHOEID^. 



less acutely crinkled ; the white submarginal line less prominent, and the border a little paler : 

 secondaries slightly paler : prothorax less rufous. Expanse of wings 44—47 raillini. 

 Dharmsala ; July. 



This species will stand between H. derasa and H. indica ; in colouring, though not in 

 marking, it is nearer to the hitter. 



THYATIRA, Hiibn. 



Thyatira batis, var. cognata. (Plate CXXV. fig. 12.) 

 Thyatira cognata, Moore, Proc. Zool. Soc. 1^88, p. 406. 



A little duller than typical T. halis, and with the central dorsal spot of the primaries 

 obsolete, giving the insect nearly the character of T. vicina of Java ; secondaries darker than 

 in most examples of T. batis. Expanse of wings 40-45 millim. 



Dharmsala. 



" At sugar, and from larvte on raspberry ; the larv:e found IGth June, pupie 20th. A 

 curiously twisting larva." 



Altliough Mr. Hocking's collection contained six examples of this form, all differing 

 from the European type in the above noted characters, there was also one example of the 

 normal pattern and coloration, showing tliat although T. cognata is the prevalent form at 

 Dharmsala, it is not at present a constant and therefore distinct species. 



POLYPLOCA, Hillm. 



Polyploca orbicularis. (Plate CXXVI. fig. 2.) 

 Palimpsestis orbicularis, Moore, Proc. Zool. Soc. 1888, p. 407. 



Nearly allied to P. flavicornis of Europe, but much browner ; the wings more sericeous ; 

 the inn(-r black line of the central belt of primaries more angular, the four lines across the 

 basal area better defined and more irregular ; the discoidal spots smaller and better defined ; 

 the secondaries darker and more uniformly coloured ; the collar frequently reddish. Under 

 surface darker and more uniformly coloured. Expanse of wings 41—43 millim. 



Dharmsala ; at sugar. 



" ^'ery like Thyatira {batis, var. coynatu) in its movements and manner of fiight." 



The genus Pv/yjjloca was founded by liiibuer for the reception of the single species 



P. xaHtli(iceros = ridens, Falir. ; it only differs from P(diiiij/si'.stis, subsequently described l)y the 



same autlior, in the nairoucr primaries of all the species.
