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, Butl.," 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 Ncs. 36 and 37 insert " §." 



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

 ably the .= ame as No. 75. 



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

 the same, then 9413 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 penera of the Cochlidi^- are not known to me in nature, 

 as Isa, Heterogenea, Nochelia and Kroncra, and some of these may not be different. 



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

 page the printer has repeated ten numbers by mistake. 



Page 18. Moeschler not 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 Prionoxyshis for Xystus, Grote, preoccupied. Dr. Bailey's 

 Angrezi may belong here when the ^ 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 NoduidcB are mostly based on general resemblance and com- 

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

 "Bombyci^e" and " Noctuo-Phalenidt " of Hubner and Boisduval. I have kept 

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

 Walsingharn's remarks in his instructive article on page jj of Papilio, vol. 2, to which I 

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



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

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

 west coast. Mr. Buder 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 Survev at Washington ; although here slight 

 modifications are concorriitant with geographical disassociation. 



Page 22. The genius Momaphana 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 antennae 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 Trtchosea, 

 the type of which is the European Liidifica. 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. Jocosa 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 Cahforniaii 

 Arthrochlora Febri/alis. I refer to the Hadenhtfr. Diphthcra Fallax will, I think, be found 

 to resemble Guenee's huioiata in the larval stages ; the moths have much m common ; 1 

 unfcrtunaely redescribed the species in one of my earlier papers, published about twenty 

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