 untried to make it a necessity to even' student of insect life, so that its 

 very moderate annual subscription may be considered well spent.

DON'TS 



Now that the collecting season has opened for most of us the 

 NEWS will again throw out a few hints in regard to what to do 

 and what not to do, even if it may be open to the charge of 

 harping on the subject too frequently. Don't put Sphinx pins 

 through Lycaenidae, or Lyc&na pins through Sphingidae. Don't 

 seal papers containing Lepidoptera, but make them uniform and 

 neat, and iron each one before putting in the specimens. Don't 

 send insects through the mail in a single box without packing, 

 unless you wish them to arrive as fragmentary evidence of your 

 foolishness. Don't send your insects to a specialist to name and 

 expect him to spend a large amount of time on them and also 

 pay all charges of expressage or postage both ways. 



A BUFFALO GNAT NEW TO THE UNITED STATES. On June 25, 1895, 

 Prof. A. Goss called me to see enormous numbers of buffalo gnats on 

 his horse, which was on the campus of the N. M. Agricultural College 

 (Mesilla Valley, New Mexico). I recognized at once that it was a species 

 I had not before seen, quite different from the common Simiilium occi- 

 dentals Towns, of the locality. Mr. Coquillett subsequently identified it 

 as Simiilium ochraceum Walker, which was until then only known from 

 Mexico. A few small gnats, a species of Sciara, were also on the horse. 

 The remarkable thing about this occurrence is that neither Prof. Townsend 

 nor the writer ever met with this .5". ochraceum in the Mesilla Valley, be- 

 fore or since, so it seems certain that we have only occasional swarms 

 coming from a distance. T. D. A. COCKERELL.
