HUNTINa 49 



sphingid larvse and another for bombycids, or noto- 

 dontids. Most sphingid hxi'va3 have a caudal horn at 

 some stage of their life, but there are species which 

 do not, while the notodontid Pheo'sia rimo'sa has a 

 caudal horn and smooth skin, and is usually mistaken 

 for a sphingid caterpillar by beginners. 



We might say that of our sphingid larvae no species 

 has spines or is hairy when full grown, but Pheosia 

 rimosa also is not spiny or hairy, and is not sphingid. 



In this identifying caterpillars nothing helps as 

 much as good pictures and descriptions and a little 

 experience, unless one can go to a collection of blown 

 specimens and compare his own with these. This, 

 however, can seldom be done out of cities and dc?fes 

 not help summer work. 



We are often asked how to keep specimens of moths, 

 and we usually answer that it depends upon one's 

 available space and the money he wishes to spend for 

 cases. There are many kinds of cabinets, cases, and 

 boxes at various prices, but they are not absolutely 

 necessary for the safe-keeping of moths. We have 

 two cigar-boxes with strips of cork on the bottom, 

 sides, and ends, in which the same specimens have 

 been kept for seven or eight years unharmed by any- 

 thing. Of course they do not show off as well as in 

 handsome white-lined cases, but they have been as 

 safe. We have some cases also for the few specimens 

 we care to keep, but we find more satisfaction in 

 studying the living creatures than in collecting dead 

 moths, however beautiful. 



Empty cocoons may be kept in any kind of box, 

 labeled.
