THE NOKTH. AMERICAN SPECIES OF INGUEA. 331 



As will be remarked, this variety has the following particular 

 in common with the variety of A. selenc, previously described by 

 me (ante, p. 183) : both have much more black than the typical 

 forms. As black absorbs more heat, may not this be a device to 

 keep the Lepidoptera warm in our cold climate ?

THE NORTH AMERICAN SPECIES OF INGUPU. 

 By John B. Smith, Sc.D. 



To the notes given by Mr. Butler in the * Entomologist ' for 

 Oct. 1894 (p. 282), I have nothing to add in the way of criticism, 

 and only a few words in explanation. At the time I examined 

 the collection there were arranged of the Noctuid^ nine cabinets 

 of twenty drawers each, and in cabinet 10 there were two 

 drawers completed ; making in all 182 boxes looked over, more 

 or less carefully. My notes on this part of the collection refer 

 to the number of the cabinet and drawer in which the species 

 annotated were found ; and after " Cab. 10, Box 2," I find — 

 " Thus far the collection was arranged." Beyond this point my 

 notes show a constant reference from the Grote boxes to the 

 Museum drawers, and the Plusii)ii were the first to be examined 

 of the unarranged material. In the Grote boxes I found his col- 

 lection of Infiiira intact, and I noted the presence of five species, 

 among them the type oiflahella. This series, then, was certainly 

 not incorporated with the remainder of the Museum material. 



After I had been over the entire series of Noctuid boxes, I 

 made in my note-book a list of all the names of the Walker 

 species which I had not then found, to serve as a guide for 

 further search; and in this list I find I. fuscescens and I.i^rodacta. 

 My book then shows that I looked over the Bombycid series, 

 finding a number of species of interest as I proceeded ; but here 

 I kept no memorandum of cabinet or drawer number. Among 

 these somewhat random notes I find the references of /. iiroducta 

 to ahrostoloides, and of I. fuscescens to I. iyr(Binlata. Concerning 

 Edema fuscescens, which is, as Mr. Butler says, described from 

 Honduras, it was referred to by Messrs. Grote and Robinson as 

 an Iiuiura, and so came upon my list. I have no note of the 

 locality of the specimen seen by me, and no special comment on 

 the species, except that it equals iDvapilata. I did not see 

 I. cristatnx, and probably, therefore, not the real type oi fuscescens 

 if the two were associated. It is pleasant to learn that cristatrix 

 can be dropped from our list, and I am quite convinced that 

 Mr. Butler is right about pjiduum. In other words, I accept 

 Mr. Butler's conclusions in this genus.
