4. ATTEVA Walker 

 ((Eta Grote; Poedloptera Clemens) 



Palpi closely upturned to "vertex, and smooth-scaled; ocelli absent; tongue 

 strong, naked'; maxillary palpi obsolete; antenna? smoothly scaled, with short 

 segments. Wing form much like that of Yponomeuta (fig. 198); the hind wing 

 more or less translucent at the base, more ample than usual. All veins present 

 and well separated. Hind tibiae smooth in female, hairy in male. 



Larvae (fig. 207) social in a web on Simarubaceae; much like those of Yponomeuta, 

 but with two. setae instead of one on the leg-base of the mesothorax. Pupa aber- 

 rant, Pyraloid, with strong lobes representing pilifers, meeting in the middle line, 

 so as to leave a suture running forward from the base of the tongue; labial and 

 maxillary palpi "almost completely covered; antennae reaching tip of wing, sepa- 

 rated by hind legs and tongue; frontoclypeal suture partly preserved, but epicranial 

 suture absent; seventh segment of abdomen free in male, but no deep suture 

 between ninth and tenth segments. 



Atteva is a tropical genus of both hemispheres; our species was probably intro- 

 duced from South America. It has been put in various groups, and even made the 

 type of a family, Attevidae. 



1. A. punctella Cramer. Fore wing with alternate pale yellow and bright 

 orange, rarely brown, bands; the yellow bands wider and cut into rounded spots 

 by a fine black network. Hind wings translucent, smoky. 25-30 mm. (aurea 

 Grote). (H 48:36.) 



Larva social; in a web on Ailanthus. 



New York to Illinois and south. 



5. URODUS Herrich-Schaeffer 



(Trichostibas Zeller) 



Antenna? without pecten, no ocellus; eyes very large; front strongly tapering 

 below, the palpi hardly extending beyond it; tongue weak. Hind tibiae with some 

 loose hairs above, at base. Fore wing narrow, oblong; costa arched, apex bluntly 

 rounded. All the veins preserved and free; R 5 running to apex; accessory cell 

 cutting off the upper angle of the discal cell obliquely; with R 2 arising from 

 beyond its middle, CUj and Cu 2 somwhat approximate and strongly curved at base, 

 starting off from the Cu-stem at right angles; 2d A forked. Hind wing ample, 

 translucent; anal angle slightly lobed; all veins present and well separated; Sc 

 and R parallel, not closely approximated. CUj and Cu, curved and widely separated 

 fro mthe rest. (H 29:66, as Cydosia majuscuta) . 



The genus is a good sized one in South America, and looks more like a Pyro- 

 morphid than a Tineid. 



1. II. parvula Henry Edwards. Blackish, immaculate. 20-25 mm. (calligera 

 auct. ) 



Larva on Persea. With stiff bristles and yellow head. Cocoon oval, formed of 

 regular, open trapezoidal meshes in oblique series; suspended by a thread which 

 extends down along the side of the cocoon. The cast larval skin is ejected through 

 a hole in the bottom ; the pupa emerges through a similar hole in the top, before 

 eclosion. 



District of Columbia; Florida. The northern record is based on a single speci- 

 men which may have been a stray.
