NOTES, ERRORS AND OMISSIONS. 



Page 4, line 2, for "order " read "sub-order." 



Page 7, line 15, for " pulpi " read "palpi." 



Page 7, last paragraph, for " I do not wish to " read " I cannot." 



Page 9, add " Metathetis, BiitL," to the genus Hemaris. 



Page 10, the species "Procne" is probably East Indian; the type has been unfortunately 

 abstracted from the collection of the Academy of Natural Sciences of Philadelphia. 



Page 13, last line, for " Meuet," read " Menet." 



Page 13, between Nos. 27 and 28 insert " Echeta." 



Page 14, between Nos. 35 and 36 insert " Philoros." 



Page 14, between Nos. 36 and 37 insert " ." 



Page 15, after No. 70, Nevadensis, insert Behrii, Sir., as a synonym. Also No. 68 is prob- 

 ably the same as No. 75. 



Page 16, Nos. 91 and 92 may be forms of Lepfarctia ; Nos. 94 and 95 may not be different ; if 

 the same, then 94 is a synonym of 95, but the two genera are different ; I have examined 

 both Echo and Bivittata ; 123, 125 and 128 may be the same species. 



Page 17, No. 178 hardly belongs to the generic group to which I have referred it ; I should 

 now rather regard it as belonging to Tortricidia; the singular shading on primaries 

 vaguely takes the shade of the "Dog's Head " on the fore wings of the butterfly of that 

 name. American species of several eenera of the COCHLTDI^-E are not known to me in nature, 

 as ha, Heterogenea, Nochelia and Kroncea, and some of these may not be different. 



Page 18, for " Dnyocampa" read " Dryoatnpa" in the synonymy of No. 227. On the same 

 page the printer has repeated ten numbers by mistake. 



Page 18. Moeschlernot Butler is, I believe, the right authority for Eulimacodes, but I have 

 not been able to see the paper in which the name is proposed. 



Page 21. I have substituted Prionoxystus for Xystus, Grote, preoccupied. Dr. Bailey's 

 Angrezi may belong here when the g is known. 



Page 21. On the authority of Mr. Henry Edwards I keep No. 359, Pulcher, Gr., from 

 Colorado, as distinct from No. 358, Hyperboreus, Moeschl, from Labrador. 



Page 22. The divisions in the Noctitidce are mostly based on general resemblance and com- 

 parative characters. They have no absolute scientific value, except in the case of the 

 " BOMBYCI^E " and " NOCTUO-PHALENIDI " of Hubner and Boisduval. I have kept 

 (in the Bombyces, etc.) the older collective terms which I found, but I agree with Lord 

 Walsingham's remarks in his instructive article on page 77 of PAPILIO, vol. 2, to which I 

 refer the student for the rules governing the termination of family and sub-family names. 



Page 22. Whether we hive any other species of the genus Habrosyne, except " Gosse's 

 Arches," is doubtful. Mr. Henry Edwards thinks that the European species occur on the 

 west coast. Mr. Butler was kind enough to point out to me the curious difference in the 

 number of undulations in the transverse lines on the primaries, which divides the Japanese 

 species from the European. The genus is an example of the kind I have called Progenera, 

 in a paper published by the Geological Survey at Washington ; although here slight 

 modifications are concomitant with geographical disassociation. 



Page 22. The genius Alomaphana differs from Feralia by the presence of ocelli, the smoother 

 and thinner vestiture, the more prominent head and larger compound eyes. From Diph- 

 thera Fallax by the pectinate antennas and wider clvpeus. The delicate green species, 

 easily faded, may be known by the pale secondaries being also tinted with green, tender 

 and somewhat transparent. Early in the spring the moth has been found by Professor 

 Kellicott about Buffalo. The genus Charadra of Mr. Walker is different from Trichosea, 

 the type of which is the European Ludifca. The structural differences between these 

 three green Noctuids are very strong, though, in addition to the color, the ornamentation 

 of Comstocki and Fallax is very similar on the primaries above. J ocosa differs in design, 

 and varies by becoming suffused with black over the upper surface of the front wings. 

 Fallax is found further south than either of the other two species. The Californian 

 Arthrochlora Februalis, I refer to the HadenincE. Diphthcra Fallax will, I think, be found 

 to resemble Guenee's Innotata in the larvnl stages ; tht: moths have much in common ; I 

 unfortuna'ely redescribed the species in one of my earlier papers, published about twenty 

 years ago, as a Diphthera. Innotata belongs to a distinct section of Apatela.
