246 ENTOMOLOGICAL NEWS. [Oct., '02 



The Denton Bro's. , of Wellesley, Mass., who handle large 

 numbers of lepidoptera every season and who have almost 

 everything sent them in papers, tell me that they put every- 

 thing, regardless of whether greasy or not, into gasoline, 

 papers and all, and leave for two weeks, then take out and 

 spread to dry without removing from papers. In this way 

 they claim the grease is all drawn out of the insects by the 

 paper, and when dry they are as fluffy and fresh looking as 

 though never wet. If taken from the papers they say that 

 they will not look as well as though dried in the envelopes. 

 Incidentally this treatment also kills any insect pests that may 

 be among them. 



Concerning the tendency of specimens which have been dried 

 out of shape and relaxed to warp, I think that they are always 

 more or less in danger of eventually returning at least in some 

 degree to their first shape if exposed to dampness, but I think 

 the danger is very much lessened by thoroughly damping in 

 the first place. They should be left in the damping box until 

 well relaxed even if it takes a week. If plentj^ of naptha- 

 line flakes are scattered over the surface of the sand they will 

 not mould for many days if ever. This is better than carbolic 

 or anything else that I know of. The only way to be sure of 

 keeping any specimens absolutely flat is to put them up in the 

 Denton tablets, but this is rather expensive.
