Family 40. EUPTEROTID^E 



(Lasiocampidas, Notodontidas, Bombycidae, in part) 



Head and body normal for the superfamily; thorax with a longi- 

 tudinal crest in Apatelodes. Fore wing in the Apatelodinae (fig. 425) 

 with all veins preserved, R 2 and R 3 , and R 4 and R 5 long-stalked; M, 

 very shortly stalked ; M 2 nearer R-stem than Cu-stem, the discocellulars 

 transverse; Cu 2 arising more than halfway out on cell. Hind wing 

 in our species with Sc and R very closely approximate on basal third 

 of cell, almost obliterating R x ; frenulum normally developed ; M x 

 short-stalked, M 2 and Cu 2 as in fore wing. 



Caterpillar strongly flattened, with at least a few scales or hair 

 scales; prolegs more or less stretched out laterally. Secondary hair 

 (in our species) on mandibles, base of maxillae, and labium, but not 

 on distal part of maxillae and labium, clypeus, or labrum. No caudal 

 horn. Pupa resembling that of the Notodontidae ; maxillaa very short, 

 the fore and middle legs meeting on the middle line behind them; 

 abdomen finely punctate, with a row of beading on each movable seg- 

 ment; not clothed with fine setas; second to seventh segments of abdo- 

 men with flange plates at anterior and posterior margins; cremaster 

 short or absent. 



Our single genus represents the Apatelodinas, which are mainly South 

 American; in the Eupterotinae, of the Old World, R 2 and R 3 are com- 

 pletely united, Sc and R of the hind wing are more promptly diver- 

 gent, and the frenulum is weaker. 



APATELODES Packard 



Palpi barely exceeding front (torrefacta), or moderate and upturned (angelica) ; 

 fore wing subfalcate (fig. 425), with outer margin bent at middle and concave 

 on upper half, costa nearly straight. Our species have one or two transparent 

 subterminal spots. 



1. A. torrefacta Smith and Abbot. Outer margin even. Pale gray, disc below 

 costa and outer margin somewhat darker; lines fine, dark brown, continuous; 

 antemedial excurved, postmedial bent out below costa and waved somewhat on 

 veins; two fainter lines across median area; a brown patch on inner margin 

 before A; rarely almost obsolete. Hyaline spot small and single. Hind wing red- 

 brown, with a dark and pale postmedial shade parallel to outer margin and ending 

 in one or two deep brown bars at inner margin. Upper side with a strong dark 

 brown shade in cell. 35-40 mm. (H 40:20.) 



The light form floridana H. Edwards with the spot on inner margin smaller and 

 light chestnut brown, in place of black-brown, is commoner southward. 



June and July. Caterpillar with dark body and fine and dense light yellow 

 hair, with a series of small mid-dorsal black pencils, those on meso- and meta-
