The Inflation of Larvae, 

 BY FRANK A. MERRICK. 



The growing interest in the breeding of I^epidoptera from 

 the egg, working out life histories, or from the larvae to se- 

 cure perfect and authentic imagoes for the collection, empha- 

 sizes the importance of preserving the larvae for future com- 

 parison. 



The advantages of inflated larvse over those that are pre- 

 served in liquids are manifold, possibly the chief of which is 

 the ability to pin each species in the cabinet with its imago, 

 thus greatly enhancing the value of the collection. 



In taking up the inflation of larvse at the Merrick Museum 

 a few weeks ago, we found that, so far as we could ascertain, 

 the apparatus in use for that purpose, failed to meet the im- 

 portant, I might say vital, factors required of such apparatus, 

 which we assume to be First, that the arrangement for infla- 

 tion of the skin shall be susceptable of the most delicate ad- 

 justment ; that it shall be instantly changeable to a greater or 

 less pressure ; that the pressure shall be constant as to force, 

 and automatic. Second, that the temperature of the oven 

 shall be equally controllable by the operator, and that it shall 

 be impossible to produce a heat that shall scorch the most del- 

 icate skin, producing discoloration, or singe the hair of the
