delicate wings. The structure of the fore legs this family stands 

 midway between the Nymphalidae and the Papilionidae. The fore 

 legs of the female are always perfectly formed, though usually 

 slightly smaller than the middle pair; while those of the male are 

 always more or less atrophied, yet never to the extent that pre- 

 vails among the Nymphalidae. The family Lycaenidae is divided 

 into two subfamilies: the Lemoniinae and Lycaeninae. The Le- 

 moniinae are distinguished by having the labial palpi minute, only 

 the minute apical joint surpassing the face; fore wings provided 

 with a distinct internal nervure; hind wings scarcely channeled to 

 receive the abdomen, furnished with a precostal nervure, the 

 costal nervure only running to the middle of the costal margin; 

 fore tarsi of male, with rare exceptions, without spines or claws. 

 The Lycaeninae have the labial palpi well developed, porrect, half 

 or more of the middle joint surpassing the face; fore wings with 

 excessively brief, hardly perceptible, internal nervure; hind wings 

 channeled on basal half to receive the abdomen, without a pre- 

 costal nervure, the costal nervure running nearly to the end of 

 the costal margin; fore tarsi of male armed abundantly beneath 

 and at tip with spines. [This article is largely made up from the 

 excellent treatise on classification in Scudder's " Butterflies of the

THE following may perhaps be of interest to the readers of the ENTO- 

 MOLOGICAL NEWS, especially to any such as are particularly interested in 

 the Dragon Fly and its life habits. It is concerning the time required for 

 the nymph forms of the larger species of sEschna to mature. According 

 to all the writings by entomologists to which I have had access, little is 

 definitely known about this part of the subiect. Some of them, and amon.i; 

 them Packard claims that two or three years is required for the growth 

 of the nymph from the time it hatches from the egg until the winged form 

 appears. During the past Summer I had an opportunity to settle this
