length near the posterior of the segment ; posterior segment bilobed, each 

 lobe armed with two short fleshy ? processes, of which the outer is the 

 longer ; " breast-bone " of a pale yellowish color, its projecting end 

 divided into two rather blunt, laterally rounded, points. A dorsal row 

 of processes similar to the lateral ones is suspected, but was not definitely 

 made out. Color of the living larvae, pinkish, approaching orange ; 

 length, 0.08 of an inch. 



The reading of the paper elicited the information that the insect had 

 committed serious depredation upon clover-seed in Tompkins, Seneca 

 and other counties in Western New York, during the past year. In 

 Seneca County, fields of clover which had been kept for seed, proved to 

 be not worth the cutting. It was also stated that a worm similar to those 

 in the heads had been discovered preying upon the roots, but these are 

 probably the same larvae, which having matured, had left the heads for 

 their pupation in the ground, where the Cecidomyidae larvae frequently 

 remain unaltered for a considerable length of time. 



The extent of the ravages throughout our country of this newly dis- 

 covered insect, which promises to be of considerable economic import- 

 ance, will be an interesting subject of inquiry for the ensuing summer ; 

 and the interesting question also arises, now that its hidden covert has 

 been detected, will the species also be discovered in Europe, whence the 

 red clover was introduced in this country.
