PACHYRHINA. 351 



so OQ the last two segments. In the female one specimen has 

 the marks as in the male but they are rather more extensive ; the 

 other has a black baud on the hind margin of each segment. 

 Traces of a black narrow side line in both sexes ; belly yellowish. 

 Leys wholly yellow ; tips of femora and tibiae narrowly black ; 

 tarsi blackish. \Vinys very pale grey; subcostal cell dark brown, 

 prongs of fork of upper branch of 4th longitudinal vein issuing 

 quite separately from discal cell. Halteres yellowish. 



Length, 3 12-14 millim. ; ? 15-18 millim. 



Described from several males and females in the Indian Museum 

 from Katihar, 30.xi.09 (type tf ), Bhoguon, 20.xii.09, both Purneah 

 district (Paiva); Maddathorai, Travancore State, 17.xi.08 (type $ ) 

 ( Annandale} ; Bindukhera, Naini Tal district, base of Western 

 Himalayas, 3. iv. 10, taken in company with P. javensis, Dol. ; 

 Madhupur, Bengal. 13.X.09 (Paiva)', Mangaldai district, Assam- 

 Bhutan Frontier, SO.xii. 10 (Kemp}; Pusa, 31. iii. and 4. iv. 11 

 (Gravely}. One female from Ceylon is in the Vienna Museum. 



Type c? and $ in the Indian Museum. 



Its bright colour, the yellow and black distinctly demarcated, 

 exactly resembles P. javensis, and it may be but a variety of that 

 species ; yet the abdominal marks seem so pronouncedly different 

 that I have ventured to regard it tentatively as distinct. On each 

 segment is a triangular rather elongate (especially on -the long 

 2nd segment) shining black spot which shows no tendency to form 

 a band on the hind margin. The base of the ovipositor is 

 distinctly blackish. The front femora show no sign of the broad 

 blackish band present in P. javensis. The two prongs of the 

 upper branch of the 4th longitudinal vein quit the discal cell well 

 separated. 



Two males in the Pusa collection bred from larvae found under 

 the earth in rice-fields at Pusa may be this species, though they 

 are smaller and more slender (12 millim.). The median dorsal 

 thoracic stripe is entire and clearly cut to its extremity on the 

 anterior margin. They are dated IG.ii. and 26. ii. 1910.
