impar. I have examples of the males of all the four forms before me 

 For the females I have seen only the allotype of P. fraseri, Selys 

 description and wing-figure of P. dispav {Mo7i. Calopt., p. i68, pi. v, 

 fig. 3) and the same writer's very brief description of the female 

 of P. impar {Bull. Acad. Belg. (2) VII, p. 441 (1859). 



I have been able to compare the males with those of a number 

 of other species of the genus in my own collection. Of females, 

 which are rare in collections, T have seen only two specimens of 

 P. brunnea, Selys, from Burma, and a figure of the wing of P. 

 formosa, Selys, given by Dr. Ris (Supplementa Entomol. i, p. 53, 

 fig 5). On the evidence before me I can say that whilst the males 

 of the genus show very remarkable differences in colouring and wing 

 shape as between species and species the females are all (so far as I 

 know) very much alike. For example, the males of P. jraseri, P. 

 formosa, and P. brunnea are so different in appearance that at first 

 sight one would think them to belong to three different genera, 

 whilst the females require a tolerably careful scrutiny for their 

 separation. 



Hence in defining the section dispar it is obvious that the male 

 characters must be entirely relied on, and especiall}'' those of the 

 hinder- wing. 



When de Selys in his ''Monographic des Calopterygines " 

 characterized the group dispar of his genus Euphaea he was not 

 acquainted with either of the other species here included. So that 

 I am able to offer a fuller definition of the group or section, at the 

 same time removing from it his E. decorata, which as Ris {loc. cit.) 

 has noted falls into a distinct group, decorata-compar-jormosa. 



I suggest then the following amended definition for the section 

 dispar of the genus Pesudophaea. 



The section comprises species of Pesudophaea in which the 

 fore-wing of the male is entirely hyaline (save that 

 mature specimens may have the apical margin outlined 

 with brown beyond the pterostigma). 



Hinder-wing gradually increasing in breadth almost to the 

 level of the basal end of the pterostigma ; its apex 

 very regularly rounded. 



Its greatest breadth bears the proportion to its greatest 

 length of between i : 4 and 1:5. 



Its apical part rather abruptly opaque, brown or black ; the 

 opacity covers frofn one-quarter to three-sevenths of the 

 wing length and its inner margin lies transversely at 

 right angles to the long axis of the wing. There is no 

 metallic green or blue colouring on the wing. 



The regular curving of the apex of the hinder-wing exists onh' 

 in the males. Its character is' well shown in the accompanying text- 

 figure for which I am indebted to Messrs. H. and F. K. Campion. 



The apex of the fore-wing is of the shape more usually seen 

 and differs but little from that of allied genera such as Bayadera 

 or Anisopieura.
