The Glow- Worm and Other Beetles 



the final transformations take place. Let us 

 pass in silence over this long period of repose, 

 during which the Sitaris, in the form of a 

 pseudochrysalis, slumbers at the bottom of 

 its cell, in a sleep as lethargic as that of a 

 germ in its egg, and come to the months of 

 June and July in the following year, the 

 period of what we might call a second hatch- 

 ing. 



The pseudochrysalis is still enclosed in 

 the delicate pouch formed of the skin of the 

 secondary larva. Outside, nothing fresh has 

 happened; but important changes have taken 

 place inside. I have said that the pseudo- 

 chrysalis displayed an upper surface arched 

 like a hog's back and a lower surface at first 

 flat and then more and more concave. The 

 sides of the double inclined plane of the up- 

 per or dorsal surface also share in this de- 

 pression occasioned by the evaporation of 

 the fluid constituents ; and a time comes when 

 these sides are so depressed that a section 

 of the pseudochrysalis through a plane per- 

 pendicular to its axis would be represented 

 by a curvilinear triangle with blunted corners 

 and inwardly convex sides. This is the ap- 

 pearance displayed by the pseudochrysalis 

 during the winter and spring. 



But in June it has lost this withered ap-
