tion of the genera Anarfa and Lepipolys, proposed in the appendix, 

 being rendered unnecessary. The relationship of Basilodes to 

 Stiria, Plagioniimiciis and Stibadiiun had escaped me, but I feel 

 sure that I am correct in placing Pityochromus and allies with 

 Stiria rather than with Lygranthcecia or Schinia, from the structure 

 of the thorax, which is very similar in all these forms and quite 

 different from the HeliotJiince. Any one who has these species, 

 and will so arrange them, cannot but so agree with me, both as 

 to the validity of the genera and the naturalness of this arrange- 

 ment. 



The species noticed in this Paper are as follows : 



Trichoclea Deccpta. Grote, n. s. 



Carneades Mocrois. Grote. 

 ■ Mamestra Bella. Grote, n. s. 



Ufeus Sagittarius. Grote, n. s. 

 " Tricorthosia Parallela. Grote, n. s. 

 • Tceniocanipa Peredia. Grote, n. s. 

 , OrtJiodes Nitens. Grote, n. s. 



NEW FORMS OF THE GENUS ALYPIA. 



By Henry Edwards. 



Alypia MATUTA. n. sp. 



The species figured by Abbot and Smith, p. 87, pi. 44, is cer- 

 tainly not the well-known A. octomaculata, F. to which it is referred 

 by the above authors. A comparison of the figure of the larva 

 with that of A. octonacnlata will support this view, as that given 

 by A. and S. is wholly bright lemon-yellow, with waved trans- 

 verse lines of black, and with black spines. Several examples 

 of the imago exactly agreeing with Smith and Abbott's figure 

 have passed through my hands, and I venture to describe this 

 form by the above name, believing it to be abundantly distinct 

 in all its stages from the common species. The spots are con- 

 siderably larger and differ much in shape from those of A. 8. 

 maculata the basal spot of which, in the primaries, is either 

 rounded or ovate, the outer one also ovate, with the edges even. 

 In the present form the basal patch is sub-triangular in outline, 

 straight along its internal margin, somewhat rounded costally, 

 and terminating towards the base of the wing in a fine point on 

 the median nervule. The outer patch is ovate, but with its an- 

 terior edge irregular in outline and somewhat constricted in the 

 middle. The secondaries have the basal third pure white, not in 

 any way interrupted by black, and the outer spot is much larger 

 and more pyriform in shape than in A. 8. inaciiiata. On the lower
