274 Mr. T. D, A. Cockorell — Descriptions and 



In the obsolete stigma this resembles Anthoglossa, but 

 the marginal cell is longer and the second s.m. is narrowed 

 above. The eyes are hairy as iu the male. 



Paracolletes marginatus, Smith. 



Victoria, Feb. 1901 (C. F., Turner coll.) ; Cheltenham, 

 Victoria, 1909 {French ; Froggatt coll.). 



These are males, and are almost exactly like T. venustus, 

 except that the eyes are entirely hairless, the first r. n. joins 

 second s.m. well beyond the middle, and the abdominal 

 segments have considerable black or dark fuscous hair 

 above. 



I take Smith's male (Avhich bears the type label) as the 

 type of luaryinatus. It seems very probable that P. mar- 

 ginatus arose as a mutation of T. venustus, but, according to 

 the dates given, they fly at different times of the year, and 

 presumably visit different flowers. 



Paracolletes tuberculatus, sp. n.

 densely punctured ; middle of mesothorax with a shining 

 sparsely punctured area ; scutellum depressed in middle; 

 postscutellum with an obtuse median tubercle or vei'y pro- 

 minent angle ; area of metathorax flnely transversely striated, 

 not carinate ; punctures of mesopleura well separated; 

 tegulse piceous and punctate in front, smooth and chestnut- 

 red behind. Wings strongly suffused witli reddish brown ; 

 stigma and nervures dark reddish ; b. n. falling a little short 

 of t.-m. ; first r. u. joining second s.m. before the middle ;
