22. Parageeydus portunus, n. sp., Plate V, Fig. 14, cT. 

 Habitat : Java. 



Expanse : (7,1-5 and 1-6 inches. 



Description : Male. Upperside, both wings dull liair-brown. Fore- 

 wing witli the usual ochreous lines on the costa and pale area on either 

 side of the swollen third median nervule. Underside, both wings pale 

 ochreous, profusely and evenly sprinkled throughout with minute ferru- 

 ginous spots. Forewing with the inner margin somewhat paler and free 

 of markings, though bearing two or three striee larger than the others 

 towards the base of the wing. 



This species appears to be nearest to P. iaras, Doherty, which has 

 the apex of the forewing on the underside " nifous-brown," while 

 P. jjortunus has the whole of the underside of that colour, the ground- 

 colour of P, taras is white, of P. portt0ius pale ochreous. Of P. taras 

 I have captured both sexes in the Meple Valley, middle Tenasserim, 

 iu October. 



Mr. Doherty, who takes particular interest in this group of tile 

 Lyccenidm, has recorded his feelings of doubt as to whether the genus 

 Paragerydus can be maintained as distinct from the genus Allotinus.* As 

 far as the specimens of both genera contained in my collection are con- 

 cerned, I am of opinion that the two genera may well be kept distinct. 

 The length, and consequently the point of origin, of the third subcostal 

 nervule of the forewing, certainly varies greatly, but in all my examples 

 of Pafagerydtts the upper discoidal nervule originates from the subdOstal 

 nervure well beyond the apex of the discoidal cell ; while in all my 

 examples of Allotinus it originates at the apex, which feature consti- 

 tutes a well-marked difference, and can be instantly detected by the 

 application of a little benzine to the wiag to make it transparent. 



P. portunus is described from two specimens sent me by Mr. H* 

 Fruhstorfer.
