falling to the soil. Ihe length of the lar\al stage \aries from fifteen 

 to t\venty-ti\e days with an a\erage of t\\enty days. By July lH 

 many pupae (PI. 1, Fig. 4) were found in the soil. The writer 

 neglected to ascertain the exact length of the pupal stage, but from 

 the meager observations made up to this time ventures the opinion 

 that it is about eighteen days. By the first of August many adults 

 could be found. They are a beautiful metallic color when just 

 emerged. The writer bred from the adults a species of Diptera a 

 Tach'tiiid but has not been able to ascertain the species. Subsequent 

 obser\ation revealed no eggs, so undoubtedly the species is single 

 brooded. The life-cycle is calculated to last about tifty-five tiays 

 from eggs to adults, but this is greatly iiiHuenced by the \\eathcr 

 conditions. The length of the adult stage is about ten months, 

 depending, of course, upon the time the warm days approach in 

 the spring and upon the cold stretches which inter\ene, conilitions 

 which influence emergence from their hibernating quarters. 



DESCRIPTION OF THE VARIOUS STAGES 



The Eggs (PI. I, lig. 3) are of an orange color, oblong o\ al or 

 bean-shaped. The egg has a delicate co\ering by which it is 

 attached to the leaf. Nearly e\ery egg has a sort of spine-shape 

 structure attached, although it is not exactly a spine but a part of 

 the egg covering, which, when it has dried, gives it a black streaked 

 appearance at that point. The egg measures 1 mm. in length by 

 .25 mm. in width. 



The Larvae ( PI. I, Fig. 7) when full grown ha\e the body wiiler 

 at the anterior end, tapering gradually to the anal segment and 

 co\ered with many hairs. They are co\ered with an oily substance 

 in which they often collect their excrement as they feed and travel. 

 The entire larva is black and the segments of the body possess 

 numerous tubercles bearing setae. F^ach segment of the abdomen 

 has a group of tubercles on a side abo\e the spiracles. When full 

 grown the larxae measure from 6 to 8 mm. in length. 



The Pupa (PI. [, Fig. 4) is yellow, 4 to 6 mm. in length, with 

 the wing pads ami legs of a paler yellow to nearly white. I \vo 

 setae are located on the \ertex ami two on the occupit of head. I he
