78 NOVITATES ZOOLOOICAB XXV. 1918. 



Biagi, Upper Mambare River, British New Guinea, 5,000 ft., January — • 

 April 1906 (A. S. Meek), 4 cJcJ, 1 ?, in coll. Tring Museum. 



Warren, in erecting Euthysana, fell into a double error, misidentifying his 

 own inconspicua and (presumably from memory after the specimens had passed 

 out of his hands, for an error of observation is unthinkable) in attributing to 

 his genus the <J hindtibial structure of Ptychopoda. In spite of the venational 

 variations, both inconspicua and phaenomeris are quite closely related to idaea 

 Swinh., the type of Mnesithetis, which I have sunk to Dithecodes. In the only 

 two specimens of inconspicua yet known from Dutch New Guinea (Fak-Fak and 

 Snow Mountains), possibly a local race, the distal areole is better developed than 

 m any British New Guinea specimens I have examined, and the whole structure, 

 as well as the scheme of markings, brings out to perfection the relationship 

 with idaea. It may be added that even in idaea I have seen one aberration or 

 " sport " in which the distal areole is minute in the right wing and wanting 

 in the left. 



5. Synegiodes obliaoilascia sp. nov. 



(J 9, 36-41 mm. Very similar to diffusijascia Swinh. (Tr. Ent. Sac. Land. 

 1892, p. 11), with which it has hitherto been confused. 



Forewing with termen in general slightly more oblique ; areole doable, SC" 

 arising from the cell ; coloration on an average more inclining to buff-pink or 

 salmon-ljuff, on account of rather stronger cloudings of vinaceous-pink (but 

 variable in both species) ; median and postmedian bands more oblique, so that 

 the median band of the hindwing appears more as a continuation of the latter 

 than (as in diffusijascia) of the former ; dark patch on postmedian between 



M' and SM' much less developed, oftener wanting. Hindwing with a vinaceous- 



tinged (on the underside much darker and greyer) line proximal to the post- 

 median row of dots, reaching from abdominal margin to SC. 



Khasias, almost as common as diffusijascia. Type, Cherrapunji, April 1893, 

 in coll. Tring Museum. Darjiling, \S, 1 ?, July 1886 (H. J. Elwes), in coll. Tring 

 Museum. 



I have examined the venation of very extensive ir.aterial in the genus 

 Synegiodes and find it constant ui each species — double in hyriaria (with SC 

 stalked) and in obliquijascia (with SC from ceU), single in diffusijascia , histrionaria 

 and sanguinaria. 



6. Timandra nelsoni sp. nov. 



(J 5, 32-37 mm. Exceedingly similar to convectaria Walk. {List. Lep. Ins.. 

 xxiii. 800), from N. India, Shan States, China and Formosa, sometimes supe.- 

 ficiaUy indistinguishable. Generally larger, of a deeper ochreous tone, with- 

 out the fleshy tinge which generally appears in the most brightly-coloured forms 

 of convectaria . 



Forewing with costal shade, cell-dot and generally the antemedian reddish 

 line well developed, the oblique line less perfectly straight, showing a very fauit 

 proximal convexity ; beneath rather strongly suffused, at least in and behind 

 ceU. 



S. India and Ceylon. Type cj, Madura distr., March — June 1906 (H. Camp- 

 bell) in coll. Tring Museum.
