COLLECTED IN DUTCH NEW GUINEA. 413 



1 ? . Wataikwa River, Aug. 1910. 



The types of all the above from New Guinea, Waigiu, and Salawatti are in the 

 British Museum. The synonymy, determined by Mr. E. E. Austen, has not, so far as 

 1 am aware, been published previously. The British Museum Collection also contains 

 a specimen from the Nilgiri Hills, S. India, 3000 ft., 14. iv. 1888 [G. F. HamjJson). 



Genus Thelaika. 

 Thelaira Robineau-Desvoidy, Myodaires, p. 214 (1830). 



52. Thelaika sp. ■? 



1 ? . Wataikwa River, Aug. 1910. 



Mr. C. J. Wainwright, to whom I submitted the specimen, writes : — " I should 

 place it very near to Thelaira^ but I cannot fit it into any genus exactly. The absence 

 of setse on the veins of the wings seems to remove it from Thelaira itself, as restricted 

 by Brauer and von Bergenstamm, but none of Brauer's other genera agree any 

 better . . . Note the saw-like underside of the abdomen, which resembles in that 

 respect the well-known Compsilura concinnata Mg. and Lydella nigripes Fall. The 

 Americans have considered Compsilura and Lydella as near allies on account of 

 the joint possession of this character ; it is interesting therefore to find it in another 

 species which cannot also be considered an ally. It is doubtless a case of similar 

 habits resulting in similar structures." 



Subfamily Sarcophaginae. 



Genus Sascophaga. 

 Sarcophaga Meigen, Syst. Beschr. v. p. 14 (1826). 



53. Sakcophaga invaeia. 



Sarcophaga invaria Walker, Proc. Linn. Soc. London, iii. p. 103 (1859). 

 1 $ . Wataikwa River, Aug. 1910. 

 1 cJ . Utakwa River, Sept. 1912-March 1913. 

 These appear to agree with Walker's types from the Aru Islands. 



Subfamily Muscinse. 



Genus Pollenia. 

 Pollenia Robineau-Desvoidy, Myodaires, p. 413 (1830). 



54. Pollenia sp.
