202 INSECTA. 
S. dispar; B. dispar, Fab.; Res., Insect., I, Class H, Pap. 
Noct. iii. The male much smaller than the female, his upper 
wings 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(1). ; 
Noroponta, Ochs. 
Where the inner margin of the superior wing is dentated. 
This subgenus connects itself with certain Noctuz(2). 
Sometimes the females are almost apterous, as in 
Oreyia, Ochs. 
The caterpillars are furnished with crests and pencils of hairs. 
O. antiqua; B. antiqua, Fab.; Rees., Ibid., xxxix, the female; 
ili, 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(3). 
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an arch under which the head is withdrawn.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 
(1) The Bombyz versicolor, bucephala, coryli, pudibunda, abietis, anachoreta, of 
Fabricius, or the genera Endromis, Liparis, Pygzra, and several species belong- 
ing to that of the Orgyta of Ochsenheimer. 
(2) The Notodontz of the same, with the exception, however, of the species 
called palpina, which on account of its large and compressed palpi, and spirally 
rolled proboscis, should form a separate subgenus, connecting the Notodontz of 
that savant with his Calypirz, and which I place at the head of the Noctuz, in 
order to proceed thence to Xylena, Cuculia, &c.; some of the Notodontz have the 
thorax and crest, a character which appears more peculiar to this latter section. 
There are some of them in which the inferior palpi are strongly compressed. See 
our general observations on that division of the Nocturne. 
(S) Add O. gnostigma, Ochs. The others will be Sericariz.
