SCIENTIFIC NOTES AND OBSERVATIONS. 57 



nomenclatorial arrangements. In these, I first use again genera like 

 Hemaris (bombi/liformis, fnclfonnisj, Aellopon, PhleijcAhoutius, 

 Paonios, names now in general use. In America, we have no Smeriii- 

 thus generically identical with populi. Our genera are : Copismcrinthus 

 (^cerisii, ophthalmicus) ; Eusmcrinthiis (^<j emi aatus Jamaicensi s) ; Fnonias 

 {excaecatns); Gala si/ nib ol us [astiflus, nii/ops); Cressonia (ju(jla)Klis); 

 Triptogon (modt'sta). In arranging the material here in the Roemer 

 Museum, I have been able to go over the structure of the European 

 species carefully, and, if the result of my literary researches cannot be 

 contradicted as to what we must consider the type of the generic names 

 in existence, then my nomenclature must be followed. It is of the 

 highest interest, for the study of geographical distribution, that the 

 types should be fixed and the details of their structure understood. 

 Very interesting is the fact, pointed out by me first, twenty and more 

 years ago, that we have a strictly congeneric species with oceHatns in 

 Canada and California, but none with populi or tiliae. My first 

 Buffalo Check List, in the Bulletin 2,224, has priority over Butler's 

 revision of the family ; the second, 3,220, was published in 1877. The 

 difficult question relates to the restriction of generic names proposed 

 originally for mixed genera ; it may be that the full literature will give 

 us a dift'erent result for some of the genera in the family. But for the 

 Smeriiithinae, the Fhalaeuoides of Borkhausen, I believe the above 

 result to be final, as nearly so, at least, as I am able to make it. The 

 genera established by me are valid in my opinion. I have had no 

 chance to study the Asiatic species. — A. Radcliffe Grote, Roemer

Generic Names in Apatela. — The object of this brief note is to 

 give the types of the generic names already proposed for the species of 

 Apatela or Acronycta of authors. I do not know the types of Dr. 

 Chapman's more recent genera Viminia and Guspidia. The first is 

 the type of the genus. 



Apatela Hiibn., 1806; type A. aceris (Grt., 1875). 



Triaena Hiibn., 1818 ; type A. psi (Grt. restr.). 



Jocheaera Hiibn., 1818 ; type A. alni (sole species). 



Acronicta Ochs., 1816 ; type A.leporina (Grt. restr., 1874). 



Arctomijscis Hubn., 1818 ; type A. euphrasiae (Grt. restr.). 

 This latter term is evidently intended in the Verzcichniss to replace 

 Apatela of the Tentamen, a name used in the Verzeichniss in a collec- 

 tive sense. From this use of Apatela I take the family name, 

 Apatelidae. I selected one of the species of ArctomyKcis, as the type 

 of this genus, not strictly congeneric with aceris ; while we have a 

 species in North America, sperata, which seems to agree with 

 euphrasiae. In the long spatulate hairs and habit of pupation the 

 North American genus Harrisimemn» resembles Jucheacra, so that I 

 have little doubt that this genus also belongs to the Apatelidae. The 

 larva of Jocheaera is evidently protected by its violent colours ; that 

 of Harrisimemna by its resemblance to a withered leaf moved in jerks 

 by the wind. 



Pharetra Hubn., 1818; type A. atirtcoma. 

 Through some oversight I gave a ur i co m(r iormevly as the type of the 

 subgen. Apatela, instead of Pharetra. Mr. J. B. Smith says (('at. 

 109), in alluding to Avytvs : " Mr. Butler thinks this (AnytusJ much 

 nearer to Pharaetra, an Arctiid, than to the Noctnidaf.'' It might 

 appear from this that Mr. Smith recognised Mr. Butler's division of
