spines, usually arranged in two small groups and nearly all 

 pointing outwards. 



This genus consists of a single species, Telea polyphemus, 

 found in all parts of the United States. Their cocoons consist 

 of a thick, firm layer, never "papery," like those of Tropaea 

 tuna. The cocoons are pale grayish tan in color, ovoid in shape, 

 blunt at the ends and usually fastened between two leaves. 

 It never has an opening at the end with loose fibers across it, as 

 many cocoons have. It is found suspended from twigs where 

 it often fastens the leaf to a tree and is also found on the ground 

 among the fallen leaves. 



Telea polyphemus Cramer (Figs. 11 and 13). — Color yel- 

 lowish brown, with darker brown around margins of spiracles, 

 and appearing at various places on surface as the age increases; 

 face parts not elevated, always white between the antennas, 

 the white strip narrowing down to the proximal margin of the 

 labrum and concave on its lateral margins; prothorax and 

 mesothorax with faint transverse striations, remainder of body 

 surface smooth, with the exception of longitudinal wrinkles 

 on the metathorax and first abdominal segment and some 

 slight dorsal impressions; antennae of male five-sixths the length 

 of wings on the meson, length twice the width; meeting on the 

 meson for more than half their length; antennae of the female 

 two-thirds the length of wings on the meson, length three 

 times the Madth, separated by the legs and ending slightly 

 below tips of the first pair; labrum variable, tuberculate, 

 generally five or six sided, the distal margin either slightly 

 or deeply bilobed; maxillae triangular in outline, the mesal 

 length greater than greatest width; mesothorax with wing 

 tubercles prominent, broadly elevated, with a distinct apex 

 marked by an angular furrow on the caudo-mesal margin; 

 first wing with its anal angle broadly rounded, below cephalic 

 margin of fourth abdominal segment; margin of second wing 

 entire in the female, slightly emarginate in the male, visible 

 along entire dorsal margin of first wing, and produced below anal 

 angle of first wing, extending about two-fifths of the distance 

 across its caudal margin; mesothoracic spiracles with their 

 cephalic margins strongly convex. Length, retracted, 25-35 mm. ; 

 expanded, 30-40 mm. ; girth, about 50 mm.
