68 B. Brune^tti : Notes on Oriental Syrphidse. [Vol. it, 



H. cclcbcr, O. S. 



H. curvigastcr, Macq. 



H. aenuSt mihi, sp. nov. 



These three are quite distmct from all the other species, and 

 ma}' be instantly recognised respectiveh' by the perpendicular face 

 and incrassated hind tibise in celeber ; the transverse bands of 

 pubescence on the thoracic dorsum in curvigaster ; and the wholl}^ 

 aenous and Eristalis-like appearance of my new species. 



H. caudatus, Meij. 



H. tuberculatus, mihi^ sp. nov. 



These two species stand out from all others by their elongated 

 abdomens, m}^ new species being easily differentiated from Meijere's 

 by tlie presence of the strong denticulation of the middle tibise, a 

 feature which he does not mention as being present in his specimen ; 

 the latter was a (f , the middle legs of which were, moreover, not 

 missing, as he describes their coloration. 



H. pilipes, Dol. 



The author figures his species, and distinctly shows the thick 

 pubescence of the first pair of femora and tibia;, the mid die pair being 

 nearly bare ; so that the specimen in the Indian Museum collec- 

 tion named " pilipes, Dol.," by Bigot is erroneously identified. 



This specimen ( cf ) I have figured in pi. xii, figs. i8, 19, 20, a 

 lateral view being given, because the specimen is partly curled up, 

 and also to show the formation of the anal segments. The 

 anterior and middle legs are also shown, the hind pair being 

 missing. It approximates to insignis, Dol., but the hairy middle 

 legs separate it ; I therefore figure it, so that perhaps some other 

 dipterologist maj^ recognise it. In the Indian ^Museum collection 

 are a cf and 2 approaching pilipes, Dol., but they have clear 

 wings and no yellow hair on anterior legs. This species (a & from 

 Calcutta) I also figure in pi. xii, figs. 11 and 12. 



Doleschall distinctly says his pilipes is near the pendultis, Meig., 

 of Europe, but smaller. 



H. vestitus, Wied. 



H. doleschalli, mihi (nom. noiK for in- 

 signis, Dol.). (PI. xii, figs. 7, 8, 9.) 



H« notabilis, Mcq. 



H. insignis, Wlk. 



The specific name uisignis was employed by Walker and 

 Doleschall for two different species, both in the same year (1857). 

 [ venture to change Doleschall's specific name to doleschalli and
