Discussion. — This insect reportedly (Jones, 1911) overwinters 

 in the last larval instar and feeds for a short time in early spring before 

 suspending its case from some tree, shrub, or other support. The 

 adults emerge in late spring. In 1921 Jones reared a few Florida 

 males of the type series of P. cacocnemos in Delaware and observed 

 them to emerge from September to November. This was submitted 

 as a possible biological difference from the spring-emerging E. tracyi. 

 All wild captures of this species, however, including the short-legged 

 forms, demonstrate a spring emergence. 



In separating P. cacocnemos from E. tracyi, Jones (1922) relied upon 

 the following distinguishing characteristics in P. cacocnemos: wings 

 darker than E. tracyi; legs shorter and more slender; primaries api- 

 cally more acute; secondaries proportionately longer and narrower. 

 The case of P. cacocnemos was thought to be narrower, with the plant 

 fragments less uniform in size, often possessing long slender pine 

 needles loosely diverging from the case. Jones also thought that the 

 smaller subcostal cell (with Rs fused for a short distance to Sc+Ri) 

 was perhaps a specific difference. 



I consider all of these differences to be variations of a single species 

 since intermediate conditions exist for each character and there appears 

 to be no correlation among any of them. The coloring of the wing 

 depends largely on the relative number of intact scales. Specimens 

 with a short subcostal cell were found to have legs approaching the 

 longest extreme. The cases themselves, although slightly variable, are 

 certainly much less so than certain other species of psychids, e.g., 

 Oiketicus abbotii.
