New Lepidoptera collected by Mr. T. A. Barns 69 



the underside is less curved on the fore wing and almost straight on 

 the hind wing. In cellules lb and c of the fore wing is a pale ochreous 

 patch distal to the postdiscal line, and generally a similar patch 

 proximal to the discal line. The submarginal line on the fore wing 

 ends at the apex ; in the typical form it ends at vein 8.

Charaxes eupale Drory, dilutus Roths, and subornatus Schultze. 



The forms of Charaxes comprised under the above names present an 

 interesting group. All are similarly coloured and exhibit similar and 

 variable markings. Our knowledge of the distribution of these forms is 

 now well advanced, and series of all are contained in the Hill Museum. 

 We have therefore attempted to analyse the group with a view to 

 ascertaining how many definite forms exist, and whether such forms 

 could be grouped together under one or more distinct species. 



Sixteen dissections of the genitalia were made and drawings prepared 

 by Mr. Birbel. When these were compared with the insects the results 

 were found to be unsatisfactory. It was at once apparent that much 

 variation existed in the genital armature, and these variations were 

 not in agreement with the differences observed in the wing-markings. 



The dissections, drawings, and insects were submitted to Dr. Jordan 

 for an opinion. He very carefully examined them, together with 

 further specimens in the Tring Museum, and reported that no reliable 

 distinction could be obtained from the genitalia. He thought that 

 probably three species could be made out on other grounds. These 

 results confirmed our own, with a slight difference in the grouping of 

 the three species. 



We believe that the three species may be grouped as follows : —
