Notes on the synonymy of noctuid moths. 223 



SlAVANA, Walk. 



Harveya, Grote. 

 Siavana repaiida. 

 Siavana repanda, Walker, Lep. Het. xiii. p. 1009, n. 1 (1857). 

 Harveya auripennis, Grote (see Check-List, p. 41, n. 1269).

It is extraordinary that Grote and Eobinson could have gone 

 carefully through the Museum collection without noticing our 

 seven examples of this very conspicuous species. 



Panopoda, Gtien. 



The named forms of this genus are much confused. The 

 P. riibricosta of Guenee is a variety of P. rufimargo, in which the 

 lower part of the reuiform marking of primaries is filled in with 

 black (" in the form of a tear," Guenee says). 



P. roseicosta is a combination, the male being evidently an 

 ochreous variety of the form generally recognized as P. carnei- 

 costa, whereas the female is P. rujimargo ; the name P. roseicosta 

 will, therefore, supersede that of P. carneicosta. There can be no 

 doubt on the point, for Guenee distinctly says that the reniform 

 spot is like a 2, and (by implication) describes it as black ; whereas 

 the reniform spot of P. carneicosta is said to be in the form of 

 an L, and is a variety of the other. 



P. cressonii, Grote, Proc. Ent. Soc. Phil. 1863, vol. i. p. 346, 

 pi. 3, fig. 4, is a grey variety of P. rufimargo, but I do not see it 

 at p. 41 of the Check-List for 1882. 



In my opinion the whole of the named forms are sports of 

 P. rufimargo. 



As synonyms of the above varieties, the following, described 

 by Walker, may be noted : — Ophiusa combinata, Walk. (Lep. Het. 

 xiv. p. 1436, n, 37), = P. carneicosta and Poaphila scissa, Walk. 

 (Lep. Het. Suppl. 3, p. 987), = P- roseicosta (grey variety). 



The varieties of this species may therefore be tabulated as 

 follows : — 



a. Reniform spot pale yellow. 



1. Wings above ochreous. - - - - P. rufimargo. 



2. ,, ,, grey. P. cressonii. 



h. Reniform spot with lower half black. 



1. Wings above ochreous. - - • - P. rubricosta. 

 c. Reniform spot black. 



1. Reniform spot L-shaped ; wings 



grey. P. carneicosta. 



2. Reniform spot 2 -shaped ; wings 



ochreous. P. roseicosta, 



3. Reniform spot 2-shaped ; wings 



grey. P. scissa
