(I860)'. 

 One female ; " Las Zonas, at light." — T. E. 

 I was at first inclined to think, with Mr. Edmonds, 

 that this insect was the female of No. 216 (regarded in 

 the present paper as the male of M. dedecora) ; but it 

 agrees so much more closely with the male insect 

 described b}^ Philippi under the name of Bomhyx !- rnhro- 

 grisra that I have concluded that it is that species ; it 

 also comes rather near to the description of B. rnstica, 

 which I should judge to be taken from a worn example. 



19. Macromphalia rivnhiris, n. s.* 



Primaries above granite-grey, wdth the ordinary lines 

 snow-white, of the usual form, those representing the 

 central band undulated, those representing the sub- 

 marginal line forming a partially double series of more 

 or loss lunate dashes (probably the pale borders of the 

 usual submarginal blackish lunules) ; a black disco- 

 cellular spot ; secondaries pale greyish brown, fringe 

 speckled with white scales ; thorax granite-grey ; an- 

 tenme whitish, with rust-red pectinations; abdomen pale 

 greyish brown ; under surface pearly grey ; primaries 

 with brownish costal and whitish interno-basal area ; 

 some snow-white spots on the costal border beyond the 

 middle, indicating the commencement of the outer white 

 line and submarginal lunules of the upper surface ; 

 costal area of secondaries crossed in the middle by two 

 abbreviated pale brown stripes. Expanse of wings, 

 36 mm. 



One male.

 whole of the secondaries, and the body, sericeous ; 

 primaries above with the inner line abbreviated, only 



* To this species was attached a label, ''Bomhyx affinis" Feisth., 

 but it is not iit all like that insect, which has bright red-brown 

 sccoudai'ies, like the male of Porthctria hypoleaca. '
