172 TWENTY-SIXTH REPORT ON THE STATE MUSEUM. 



the genus, as shown in two excellent articles on some closely allied 

 and for a long time confused European species, published in the 

 Stettiner Ent. Zeit., in 1858 and 1859 ; also in his valuable paper 

 published in the same journal in 1870, and a translation given in the 

 23d Ann. Report on the N . Y. State Cabinet, but for which paper 

 our intermedia might yet have been regarded identical with the quite 

 dissimilar umbratica of Europe. 



The detection of this interesting species is due to the indefatigable 

 zeal in collecting, of Mr. Otto Meske, of Albany, and to his ready 

 perception of new Lepidopterous forms or features. A pair, in per 

 fect condition, are in his cabinet, from which the above description 

 is drawn, and, as they are the only examples which have come under 

 my observation, it is probably quite rare. The female was taken by 

 him, at Albany, on the 6th of June ; the male was found at Sharon 

 Springs, N. Y., on the 15th of August, at rest upon a fence, and was 

 recognized, before being pinned, as differing from intermedia. 



The description has been carefully drawn and extended, perhaps, to 

 an unusual degree of minuteness, for the reason that the genus pre 

 sents us with species which can only be separated from one another, 

 in the imago state by very careful discrimination, and requiring for 

 their identification, a faithful delineation of inconspicuous features. 

 M. Guenee, in his Species General des Lepidopfyres, remarks, that in 

 Cucullia &quot;it frequently occurs that caterpillars the most different, it 

 might almost be said, the most opposite, produce moths so very near, 

 that it is only by great care that they can be distinguished.&quot; In 

 remarking on C. lucifuga Roesel, he says : &quot; The lucifuga of Treits- 

 chke appears to me a lactucoBj that of Duponchel is a chamomillcB j 

 that of Borkhausen seems an umbratica, as also those of Stephens 

 and Esper.&quot; The greatest confusion has existed in regard to C. olat- 

 tarice, for, according to Guenee, the canince of Rambur and the thap- 

 siphaga of Duponchel are identical with the true filattarice of Esper ; 

 the Hattarice of Her.-Sch. is thapsiphaga Treitschke ; the filattarice 

 of Boisduval is scrophularivora ffcambur ; the Uattarice of Duponchel 

 \& prenanthis Boisduval. Thapsiphaga figures as synonyms of three 

 different species. Umbratica Linn, appears as lactuccB of Fabricius ?, 

 Hiibner, Treitschke, Haworth and Stephens, the lucifuga of Esper 

 and Borkhausen, and the taneceti of Stephens. Lychnitis Engramelle 

 and scrophularioB W.-Y. so strongly resemble one another that seve 

 ral authors have believed them to be identical. Esper figures both as 

 the same species, but according to Speyer, there can be no doubt
