EXPLANATION OF LETTERING. 



NEW SOUTH AMERICAN GALL MIDGES. 



By E. p. Felt, 

 Albany, New York. 



The following accounts are based mostly on a small collection 

 generously donated to the State Museum by C. P. Alexander of 

 Cornell University. The South American gall midge fauna, as 

 shown by fragmental studies here and there, is extremely inter- 

 esting. It is sincerely hoped that collectors working in that part 

 of the world will, in the future, be able to give more attention to 

 these midges. 



Porricondyla parrishi sp. nov. 



The species described below was collected by H. S. Parrish, 

 December 27, 1912, at Bartica, British Guiana, and donated to 

 the state collections by C. P. Alexander.
