 broad with close golden tomentose pubescence. Antenna? orange, 

 2nd joint slightly longer than 1st ; 3rd reddish brown, 4-annu-

 brown. Thorax black, with very short dense golden almost 

 tomentose pubescence; sides black, pale yellowish for an inde-

 Siliguri, foot of Darjiling Hills. 



42. Odontomyia transversa, sp. nov. 



5 . Head with frons fully one-third of head, sides parallel, 

 orange, nearly bare ; vertex small, black; ocelli yellowish ; a pair 

 of rather large diagonally placed brownish spots on each side of 

 upper part of frons with indistinct outlines (possibly sometimes 

 forming a median brown spot of irregular shape and size) ; face 

 and lower part of head and postocular orbit bright yellow, bare, 

 except for a few scattered short yellow hairs; antennae orange, 

 1st and 2nd joints subequal. Thorax with dorsum black, with 

 almost tomentose golden pubescence; margins of dorsum, except 

 the anterior one, broadly yellow ; sides mainly yellowish; lower 

 part of sternopleura black ; a large brown spot on mesopleura ; 

 a similar smaller brown spot in front of wing-base. Scutellum 

 wholly chrome-yellow, very narrowly black at base; spines very 

 small, yellow. Abdomen yellow, anterior margins of 2nd, 3rd, 

 and 4th segments each with a broad chestnut-brown band ex- 

 tending nearly to the hind margin ; a darker, nearly black spot at 

 sides of 2nd, 3rd, and 4th segments contiguous to anterior margin, 

 diffused hindwards into the brown colour ; 5th segment mainly 

 dark brown ; a small dark brown spot towards each side of 1st seg-

 Palur, Madras, viii. 1915 ; sent to the British Museum. 



It is just possible that this may be viridana, AVied., though 

 his description of the abdomen does not correctly apply ; yet 

 species in Odontomyia are often so variable that the two may 

 be identical.
