Two species, Warwick Marshes, April 16 (F. M. Jones). 



The two specimens were attached to a small dragon fly, (an 

 Agrionid), with the mouth parts extended into the sutures near the 

 base of the wings apparently in the act of biting. This is the second 

 time that the writer has seen a Ceratopogon attached to an insect. 

 The first example was also taken by Mr. Jones, the flies being attached 

 to the wings of a Chrysopa. This specimen was loaned to Dr. E. P. 

 Felt in connection with his studies of the Cecidomyiidce, as a species 

 of the latter family has been recorded by Mrs. Annie T. Slosson as 

 also attaching itself to the wings of a Chrysopa. (Ent. News, VH, 

 238, 1896).
