34^ Records of the Indian Museum. [Voi,. Ill, 



my specimen is much too slender and too small to be this species. 

 It however possesses the four bristles on the fourth abdominal seg- 

 ment, and has only two dorso-central bristles on the thorax, in 

 these characters asireeins: with punctum. For the present, it will 

 be wisest to omit the nime from my list. In my collection. 



Sepsis similis, mihi. sp. nov. 



cf . Darjilinc;. Long. 3 mm. 



Closely allied to S. Punctum, F., a European species which is 

 known to extend to No th Africa. My species differs from that of 

 Fabricius by having four dorso-central thoracic bristles, and 

 by the absence of the middle pair of bristles on the fourth abdom- 

 inal segment. Minor differences are the slightly darker hind legs, 

 the wing spot reduced to a small dash , and the inner cross-vein 

 being more nearly over the middle of the discal cell. 



In the formation of the fore femora it agrees with punctum, 

 and if the number of bri^^tles on the thorax and fourth abdominal 

 segment are inconstant, the two species may be identical. 



Described from two males taken by me at Darjiling, 

 24 — 26-ix-o8, in grassy fields. In the Indian Museum collection. 



Sepsis rufibasis, mihi, sp. nov. 



&. Darjiling. Long. 3 — 4! mm. 



A handsome and conspicuous species, allied to punctum, 

 similis and himalayensis. 



The second abdominal segment is always more or less reddish 

 (above as well as at side), the colour extending sometimes to the 

 base of the third segment, above also ; the rest of the abdomen 

 showing violet, bronze and green tints, the fifth segment also, with 

 the anal appendage, being principally reddish yellow. Four dorso- 

 central bristles are present. The shape of the wing spot is as in 

 himalayensis. The fourth abdominal segment carries four bristles, 

 sometimes of unequal length (one specimen possessing a fifth 

 bri.stle). 



A principal specific character is the presence of bristles on 

 the legs, distributed as follows : Several on the apical half of the 

 under side of the middle femora, also along the whole length of 

 the middle tibiae on the hinder and outer sides. On the front of 

 the hind femora towards the tips are a few, and two are in the 

 middle of the hind tibiae, placed somewhat posteriorly. 



From himnlavensis it may be distinguished at once by its 

 wholly reddish yellow femora, all the legs being of that colour 

 except the tarsi and the hind tibiae, which are blackish. Apart 

 from any differences contained in the above remarks this species 

 resembles punctum, F. 



Described from four & & in the Indian Museum collection 

 taken by me at Darjiling, 23— 26-ix-o8, in fields.
