Crabro7iidce. 

 Owing to my desultory mode of collecting, I have not taken many 

 species of this family. The only one I have named is 



27. Cerceris desei-ta Say., which is not uncommon.

CORRESPONDENCE. 



AN INSECT ATTACK ON AN lULUS. 



Dear Sir : A friend — a careful observer of insects and their ways, 

 although not an entomologist — has communicated to me the following 

 statement : — 



" Once, and once only, and that many years ago, I saw what seemed 

 to my uneducated eye, a swarm of minute gnats making an lulus un- 

 happy. He was hastening as fast as his numerous legs could carry him 

 across a wood road — they hovering over him, darting on him, and he 

 stopping and biting at them angrily, and then moving on. It seemed to 

 me that they were puncturing him. Were they ichneumons ? If not, 

 what were they ? " 



I would be glad to learn if any similar occurrence has ever been 

 observed, or if any plausible explanation can be offered for so singular an 

 insect demonstration. I am not aware that parasites ever make a com- 

 bined attack in the manner above described. 



Albany, May 13, 1884. J. A. Lintner.
