the base of the 1st joint. The spots on the 2nd abdominal 

 segment do not nearly till the surface, but they vary in .size and 

 in one specimen coine very near to fulfilling Schiner's words. In 

 another specimen the spots on the 3rd segment are as yellow as 

 the first pair, and in another specimen the 4tli segment is wholly 

 shining black, without any trace of spots. The degree of infus- 

 cation at the wing-tip also varies; in one specimen extending 

 inwards as far as a line from the tip of the 1st vein to the outer 

 side of the discal cell, while in another ( $ ) only the outer side of 

 the 1st posterior cell is suffused. Mergui ; Margherita; Pallade, 

 Travancore, 15. x\. 1908 (Aimcaidale). These specimens were in- 

 correctly attributed by me firstly to arr/i/i-ojms, Dol.*, and subse- 

 quently to my nepaIensisf,oi which the only spf'cimen known 

 to me now is the type. The Sarawak specimen (Sibu, Sarawak, 

 2. vii. 1910 (Beebe)} referred by nie to nejyalensis and redescribed 

 {op. cit.,p. 210) is also nicoharensis 5 . Length of the specimens 

 examined by me, 5|-G| mm. I have subsequently seen further 

 specimens of this species from Pusa, 14. viii. 1907, S. iii. 1908, 

 and 17. iii. 1908, " under mango bark " ; Chapra, Bengal.
