AMBLYPODIA GEOUP OF TJIE LYC.EXID.E. 3 



friend Dr. Staudinger likewise sent me the most important portion of his collection ; 

 these two alone furnished me with considerably over 2000 specimens, without 

 which my task would have been well nigh impossible, for, with species so closely related 

 as are many of these, it is extremely difficult to differentiate them without the types, 

 especially when they are not described on the same plan. I have therefore in this 

 revision adopted a uniform plan of description for the genus Arhopala, which will 

 be easily understood on reference to the accompanying figure (Text-fiy;., p. 2). I 

 have further examined nearly all the most important collections in the kingdom, and 

 through the kindness of Herr Georg Semper, who sent me all his Philippine specimens, 

 I have been able to examine this valuable collection, so that my grateful thanks 

 are due to him, as also to many other entomologists both on the Continent and 

 at home ; and I would specially thank Mr. Hamilton Druce, who has helped me 

 frequently on various difficult poiuts. 



The genitalia have had my careful attention, and have often proved a real help in 

 settling the specific value of certain species, especially in the green division of the 

 genus Arhopala. The subgroups, as a rule, follow the main lines of a certain pattern, 

 and in all cases that I am aware of they have a definite specific value.

Both wings short and broad. Primaries with the costa evenly arched, more strongly 

 in the female, apex acute. Posterior margin excavated below the apex, then strongly 

 convex, especially so in the female. Inner margin waved : costal nervure ending about 

 the apex of the cell ; second subcostal nervule with its base midway between the first 

 and upper discoidal ; third subcostal short, rising nearer the apex of the wing than the 

 cell ; discocellular nervules upright, concave, the middle rising from the upper discoidal 

 close to its base and rather shorter than the lower, submedian nervure straight. 

 Secondaries with the costa strongly arched at the base, then almost straight in the 

 male, but slightly arched in the female ; posterior margin evenly rounded to the tail, 

 then deeply excavated and oblique to the lobe, but in the female it is excavated up to 

 the outer tail ; abdominal margin excavated above the lobe, then rounded ; first sub- 

 costal nervule rising somewhat near the apex of the cell ; discocllular nervules with a 

 slight oblique tendency outwards, straight; the second median nervule rises just at the 

 lower end of the cell ; submedian nervure straight, internal nervure straight, then 

 strongly arched. The male has a shortish tail at the end of the first median nervule. 

 The female has likewise, and in addition has another at the end of the second median 

 nervule. Antennse of moderate length; eyes smooth; palpi long, slender ; legs short. 



I have been unable to trace any record of the life-history of any species of this 

 genus, but Mr. Doherty was apparently acquainted with their eggs, for he writes
