4. ATTEVA Walker 



(CKta- Grote; P&ciloptera Clemens) 



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

 strong, naked; maxillary palpi obsolete; antennae 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 tibia; smooth in female, hairy in male. 



Larva; (fig. 207) social in a we!) on Simarubacese; much like those of Yponomeuta, 

 but with two seta; 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, Attevidse. 



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-Schsjffer 

 (Trichostibas Zeller) 



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

 below, the palpi hardly extending beyond it; tongue weak. Hind tibia? 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, 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 2 curved and widely separated 

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



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

 morphid than a Tineid. 



1. U. 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.
