316 Mr. A. G. Butler on the natural affinities of 



of the second subcostal branch, the cross-vein being 

 absent : this species, therefore, should be referred to the 

 NotodontidcB as type of a genus near Symmerista. 



A. psi and tridens, which have Notodontid larvee, are 

 referable to the genus Tricena, Hiibner, and the nearly- 

 allied form A. stric/osa to the genus Hyboma of the same 

 author : they may be placed next to Gluphisia, which 

 differs in neuration in the slightly-irregular form of the 

 second subcostal branch of primaries (which is, however, 

 similarly situated and united in the same way to the third 

 branch) ; it differs, also, in the second and third median 

 branches of secondaries being placed upon a short foot- 

 stalk. 



A. alni appears to be referable to the Noctuites, the 

 caterpillar much resembling both in colour and in its 

 clavate hairs the larva of Tinolius, the latter, however, is 

 a semi-looper, and, therefore, not nearly related to it: this 

 species is the type of Hiibner's genus Jochecera. 



A. ligustri seems to be a Noctuid, the larva being 

 smooth, green, with yellow longitudinal lines, and a few 

 scattered long hairs;* the neuration agrees with Mamestra, 

 and I should place it provisionally with that genus. 



The Acronyctce, then, will be distributed as follows : — 



Arctiid^. 

 Pharetra, Iliibner. 

 P. rumicis, P. auricoma and allies. 



LiPARIDiE. 



Acronicta, Ochs. 

 A. lejiorina, A. simplex. 



Artomyscis, Hiibner. 

 A. aceris, A. liastulifern, &c. 



NOTODONTIDiE. 



Genus — ? 

 A. megacepliala and allies. 



* Hiibner's figure makes these hairs more prominent than they really 

 are.
