The type of Walker's species, from the Bethime collection, is now in 

 the collection of the National Museum. The specimen of catherina in 

 the British Museum does not seem to be the type; but is the species 

 Mr. Grote has always so determined. Mr. Morrison's type is now in 

 the Tepper collection, and agrees in all respects with Mr. Grote's speci- 

 mens, and of course, therefore, as well with Walker's.

A specimen labeled by Mr. Morrison, and probably a type, is in the 

 collection Boston Society of Natural History. A specimen labeled 

 "type" is in the Neumogen collection.

The type of this species is in the Museum of Comparative Zoology 

 at Cambridge. I failed to find the type at Salem, in the Peabody Mu- 

 seum; but matters were there in great confusion. Since that time the 

 insects have been transferred to Cambridge, and what remains of the 

 type is found there. Staudinger's suggestion that it may be a form of 

 carnea is contradicted by the autennal characters ; but the reference to 

 Paclmobia is correct. It looks like pcctinata Grt., with the maculation 

 scarcely traceable, and there is no difficulty in recognizing the species, 

 A specimen marked " type" by Mr. Morrison is in the National Museum,
