cular median dorsal-line over the dorsal-vessel. The skin is 

 wrinkled above, and flecked above and on the sides with white. 

 The suranal plate is well roundeJ and edged 7vith straw-yelhm>. The 

 prothoracic segment is much wider than those behind, and the 

 body tapers rapidly towards the end. The spiracles are ringed 

 with light sienna-brown, rendering them rather conspicuous. The 

 thoracic and abdominal legs are pale green. 



Stage V. — Not described, but closely resembles the full-fed 

 larva. 



For a description and figure of the full-fed larva see Lintner, 

 Ent. Contr., iii, p. 150, and our Forest Insects, p. 154, IM. xi, fig. 

 6, after Lintner ; also Miss Soule (1. c). 



SiiDiinarx : — i. The freshly hatched larva is in shape like the 

 adult, only the head is larger in proportion, and the body is pro- 

 vided with bulbous glandular hairs. There are no lines nor white 

 dots. 



2. The two subdorsal yellowish longitudinal stripes probably 

 appear at the end of the 2d stage. 



3. In stage III. the whitish bloom appears. 



4. In stage IV. the suranal plate is edged with yellow. 



This is, next to Gliiphisia, the simplest, least specialized 

 Notodontian larva ; more so than that of LopJwdonta. The body 

 is without tubercles or humps ; the piliferous warts are minute 

 and the simplest markings are colorational, i.e.^ two yellowish sub- 

 dorsal bands, with no spots. In the Notodontians the subdorsal 

 lines are the first to appear, before the lateral ones. This is prob- 

 ably as near the primitive ancestor of the Notodontians as any 

 known genus, unless Gluphisia be excepted ; the larva of Lop- 

 hodoiita is nearly if not quite as simple in shape and ornamentation 

 as that of Nadata. 



Lophodonta angulosa Ahhot and Sniit/i. 



A detailed description was published in Forest Insects, p. 154, 

 comparisons being made with the larva o( jVadata gi'Masa ; but in 

 the following description some features are noted which do not 

 appear in the published description. 



It occurred at llrunswick. Me., September 8, on the oak, and 

 at Providence, R. 1., in September and early in October. 



Full-fed f.arva. — Length 40 mm. Resembling in its simple,

 while the bodv is smooth not granulated. The head is nearlv as
