LEPIDOPTERA. 297 



Sericaria, Lat., 



Where the superior wings present no dentations in their inner 



margin. 



S. dispar ; B. di<tpar. Fab. ; Roes., Insect., I, Class II, Pap. 

 Noct. iii. The male much smaller than the female, his upper 

 Avings brown, with undulating blackish stripes ; the female 

 ■whitish, with black spots and streaks on the same wings. She 

 covers her eggs with the numerous hairs on the extremity of 

 her abdomen. The caterpillar is very often injurious to fruit- 

 trees *. 



NOTODONTA, Ochs., 



Where the inner margin of the superior wing is dentated. 

 This subgenus connects itself with certain Noctuje t- 

 Sometimes the females are almost apterous, as in 



Orgyia, Ochs. 

 The caterpillars are furnished with crests and pencils of hairs. 



O. antiqua; B. antiqua. Fab.; Roes., Ibid., xxxix, the female ; 

 iii, Class II, Pap. Noct., xiii, the male. Superior wings of the 

 male fulvous, with two transverse blackish stripes, and a white 

 spot near the inner angle. The abdomen of the female is very 

 voluminous J. 

 We now come to Pseudo-Bombyces, whose caterpillars are com- 

 pelled to crawl, their feet being short, and even the squamous one 

 being retractile. Their body is oval, resembling that of an Oniscus, 

 and its skin is soldered above from the second ring, so that it forms 

 an arch under which the head is withdrawn. 

 These species form the subgenus 



LiMACODES, Lat, 



Their caterpillars seem to represent, in this division, those of 

 certain Diurnal Lepidoptera, such as the Polyommati §. 



The last of the Pseudo-Bombyces, without an apparent or at least 

 useful proboscis, also present another anomaly in their first state. 

 Their caterpillars, like those of several Tineitcs, live in portable 

 dwellings consisting of a silken tube, on which they fix fragments of 

 stems or twigs of various plants, forming little rods laid one over the 



* The Bomlyx versicolor, bucephala, coryli, pudibunda, ahietis, anachoreta, of Fab- 

 ricius, or the genera Endromis, Liparis, Pygara, and several species belonging to that 

 of the Orgyia of Ochsenbeimer. 



t The Notodontae of the same, with the exception, however, of the species called 

 palpina, which ou account of its large and compressed palpi, and spirally rolled pro- 

 boscis, should form a separate subgenus, connecting the Notodontas of that savant 

 with his Calypfrce, and which I place at the head of the Noctufe, in order to proceed 

 thence to Xylena, CucuUa, &c. ; some of the Notodontae have the thorax and crest, a 

 character which appears more peculiar to this latter eection. There are some of 

 them in which the inferior palpi are strongly compressed. See our general observa- 

 tions on that division of the Mocturn.T.
