ta. C. hentzii was certainly three weeks behind the usual time 

 of appearance, and specimens have been scarce and shy. 



While the rule has been a great dearth of both species and 

 specimens, the exception has given a few splendid series of 

 species generally considered very scarce in this region, the 

 most notable being in the Buprestidae and certain genera of 

 the Chrysomelidae. During the summer I was presented with 

 a fine little weevil that was found alive in a cargo of fruit from 

 the West Indies. 



Three New Species of Nemoatcerous Diptera. 



By D. W. COQUILLETT. 



The early stages of the following new species of Diptera are 

 to be treated of by Dr. H. G. Dyar, at whose request the writer 

 hereby names and characterizes these species in order that they 

 may be recognized in the future. So little is known in regard 

 to the early stages of our Diptera that any facts on this subject 

 will form a welcome addition to our scanty knowledge, and it 

 is fortunate for the science that so experienced a biologist as 

 Dr. Dyar is to devote a portion of his energies to this interest- 

 ing but greatly neglected field of research.
