MISCELLANEOUS. 



Descriptions of two new Species of Heterocerous Lepidoptera of the 

 Family Arctiidae. By A. G. Butler, F.L.S. &c. 



Ph^goptera, Herrich-Schaffer. 

 Phcegoptera rhodosoma, n. sp. 



In form most like P. thalassina ; primaries pale brown, trans- 

 versely streaked all over with dark greyish brown ; secondaries with 

 disco-apical area, from costa to near anal angle, dark brown, semi- 

 hyaline internally, discoidal cell whitish subhyaline, interno-anal 

 area broadly rose-red ; top of head, centre of collar, and of prothorax 

 creamy ochreous, remainder of thorax sepia-brown ; abdomen rose- 

 red, posterior segments transversely banded with black ; antennae 

 dark brown : wings below sepia-brown, primaries showing the 

 darker transverse streaks indistinctly ; secondaries with rosy area as 

 above ; head black ; thorax dark brown, coxae rose-red, remainder 

 of the legs dark brown ; venter brown, paler at base. 



Expanse of wings 2 inches 9 lines. 



Hab. Ecuador {Buckley). Type, B.M. 



Section Lophocampa, Felder. 



Phcegoptera fumosa, n. sp. 



Nearly allied to P. flavopunctata of Walker, same general pattern, 

 but the ground-colour of the wings semitransparent smoky brown ; 

 primaries — veins blackish, a marginal series of yellow or white tri- 

 angular spots terminating the nervures ; a zigzag disco-submarginal 

 brown chain-like streak (the links of the chain, where visible, yel- 

 lowish or white); a curved postmedian series of triangular dusky- 

 edged 3-ellowish or white spots ; a subcostal streak near the end of 

 the cell, sometimes inclosing a pale spot ; an angulated blackish 

 streak across the centre of the cell, inclosing pale spots ; base 

 blackish, spotted with orange; secondaries paler than primaries: 

 head and thorax dark brown, spotted with orange, collar margined 

 with orange; abdomen dark brown, with basal tufts, sides, and anal 

 segments orange : wings below much paler than above ; bod)' whity- 

 brown, dotted with orange at the sides. 



Expanse of wings 2 inches 6-7 lines. 



Hab. Brazil (Becker). Type, B.M. 



Before leaving this group I may as well record a synonym which 

 I have discovered during my rearrangement of the family. 



Halesidota albidutor and //. vitripennis of Walker are identical ; 

 they more nearly approach the group which I regard as Phcegoptera 

 than Halesidota proper; but, as a matter of fact, H. cinerea, degenera, 

 and dlbidator will form a new genus, differing considerably in the 

 neuration of the secondaries.
