no. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 269 



Exorista cecropise Riley, breeding on Samia cecropia (cf. Pergande MS.). 



Sturmia inquinata V. d. Wulp. (determined by Coquillett). Bred by Lugger from Hemi- 

 leuca maia. 



Tachina meUa Walker, from Hemileuca olivise (cf. Ainslie). 



Euphorocera claripennis Macquart, one from Hemileuca olivise (cf. Ainslie); bred from 

 Hemileuca artemis, sent by Cockered from Las Cruces, N. Mex. (Coquillett, Revis. Tachinidae of 

 America north of Mexico, 1897, p. 12). 



[Martelli (Boll. Lab. Zool. Portici, 1911) has an account of Masicera sylvatica as a parasite 



of Saturnia pavonia.] 



[Family uncertain.] 



OXYTENIS Hiibner. 



Plate XXXVI, fig. 2 (0. lamis.) 



Oxytenis IIuebner, Verzeichniss bek. Schmett., p. 150, 1816 (?1822). — Walker, Cat. Lep. Het. Br. Mua., V, p. 1181, 

 1855.— Kirby, Syn. Cat. Lep. Het., p. 770, 1892. 



Imago. — <S . Front of the head square, as wide as long, being rather short and wide. 

 Eyes moderately large. Antennae pectinated to the tip, except the two last joints; the joints 

 short, one pair of pectinations to a joint, the branches being spread out, ciliated, and a little 

 longer on the outer than on the inner side. Labial palpi stout, thick, extending well beyond 

 the front, but not so far as in Eusyssaura; second joint long and thick; third joint longer and 

 more distinct than in Eusyssaura. 



Fore wings short and broad, square at the apex, not falcate, outer edge not excavated; 

 inner angle rounded. Hind wings short, rounded at the apex-; outer edge full and rounded; 

 inner edge nearly straight. 



Venation: Of fore wing, vein II, as usual arises inside of the forward discal vein and of the 

 origin of the stalk of II 2 and II 3 and ends "half way between the end of I and II 3 . No traces of 

 VIII, so well developed in Eusyssaura. In hind wings origins of II, and II 2 close together; 

 hinder discal very oblique, passing forward and inward to meet origin of III,. [In the revised 

 nomenclature, for I read II, for II read III, etc.] 



Markings: The species known to us bright ochreous, with an extradiscal line common to 

 both wings ; that on the fore wings beginning beyond the middle of the wing and ending on the 

 costa just before the apex. Two remote white discal marks on the fore wings; no discal spot on 

 the bind wings. Beneath with two remote dark discal spots on each wing. 



[Kirby lists 13 species, all neotropical. The type of the genus, according to Kirby, is 0. 

 modesta (Stoll). Kirby 's second species (honesta Stoll) and his ninth (malacena Druce) are to be 

 removed to Eusyssaura.] 



[Dr. H. G. Dyar (in tttt., 1912) suspects that Oxytenis is not a Saturnian, but an Eupterotid. 

 "The larvae would decide, but we have none." The venation, however, is Saturnian. 1 



Eusyssaura will go with Oxytenis, being closely related to it.] 



EUSYSSAURA Packard. 



[Eusyssaura Packard, Journ. N. Y. Entom. Soc, XI (1903), p. 246.] 

 Syssaura Huebner (in part), Verzeichniss bek. Schmett., p. 150, 1816 (1822?). 



Imago. — Male. Front of the head rather short and unusually broad; it is not exactly 

 square as in Oxytenis, but is a little narrower in front than on the vertex. Male antennae well 

 pectinated to the tip ; the branches being long and ciliated, and drooping so as to be folded close 

 together as in Platypteryx, etc., not spread wide open as usual in the Saturniidaa; the antennal 

 joints are short, bearing but a single pair of pectinations, but they are so close as to appear as 

 if there were two pairs to a joint. Maxillary palpi well developed, united, quite long, much 

 longer than usual in the group, reaching down to the base of the labial palpi. Labial palpi 

 unusually large and thick, blunt at the end, being considerably larger and thicker than in 



1 [All the following genera, according to Dr. Dyar, have Saturnian venation, and yet may be Eupterotid; Lonomia Walker, Oxytenis HUbner 

 Atthtnidia Westwood, Thcrlnia Hiibner, DTaconiplcris Hiibner, and Teratopteris Hiibner. For the venation of the last, see Plate XLI, fig. 4.)
