Part III. 
(LYCAENIDAE). 
Parts I and II of this list, dealing with the Nymphalidae 
and Lemontidae only, were published by Mr. Shelford in this 
Journal in 1904 and 1905 (Nos. 41 and 45). Mr. Shelford being 
unable to continue it, suggested that I should do so—a task I have 
gladly undertaken. This Part deals with the whole of the Bornean 
Lycaenidae, the most numerous of all the Families in Bornean 
Rhopalocera. The growth in our knewledge of the Lycaenidae of 
this country may be seen from the following figures :_-Mr. Distant? 
in his great work, Rhopalocera Malayana, gives 32 species of 
Lycaenidae from Borneo. Mr. W. B. Pryer® after some 9 years’ 
collecting in British North Borneo could only record 35. species 
(1887) ; “before that, Mr. Herbert Druce® had recorded 71 collected 
in the neighbourhood of Labuan by Sir Hugh Low (1873); a 
number, which was increased to about 220 by Mr. Hamilton H. 
Druce* (1895), who had examined a large amount of material in 
the Godman-Salvin collection together with the Kina Balu and 
Labuan captures made by Waterstradt and Wahnes. Mr. Druce? 
published a second paper in 1896 increasing the total to 262; since 
that date some of the genera have been monographed and some 
new species described ; including these and the species described for 
the first time in this paper, the total number of named forms and 
varieties now recorded from Borneo is 317; of which 300 are 
- regarded here as true species. In comparison with. these figures 
it may not be out of place to mention that de Nicéville and Martin® 
recorded 238 Lycaenidae from Sumatra out of a total of 756 Rhopa- 
locera; so we may regard our present list as having some preten- 
sions to completeness.
