Genus IIiUMUorrIiaa:ia, Orote and Robinson (18G5). 



In the Annals of the Lyceum of Natural History of Xew Yorlc, 

 Vol. VIIL, 18G7, Ave gave a synoptical table of the species of this 

 genus, which I here repeat in a more complete shape, adding our 

 recently described Haemorrhagia uniformis (Sesia miiformis G. 

 & E.) from the Atlantic District. Mr. Lintner writes me that 

 this is the more usual species about Albany. Mr. Strecker kindly 

 sends me a female specimen from Labrador. This species is of the 

 size of H. thysbe, but may be known at once by the edendate inner 

 edge of the marginal band, inwardly produced at vein 5. We speak 

 of this species on page 26 of our Systematic Catalogue. It is the 

 ruficaudis X of Walker, but not of Kirby, to judge from the latter's 

 description, which will not apply to any species of Hemaris or 

 Haemorrhagia known to us. I owe to the kindness of Mr. Lintner, 

 whose entomological labors I highly appreciate, specimens of H. 

 gracilis, G. & R., taken near Albany, N. Y. This is our rarest 

 species and the slightest bodied. In fresh specimens there is a 

 narrow white inner lining above and below to the marginal bands 

 of the wings, which is alike singular and beautiful. It has many 

 distinguishing features, as will appear in the following synoptic 

 table of the species of this genus. The first species known to sci- 

 ence allied to Haem. thysbe, and differing by the edentate margin 

 of the fore wings, is Haem. buffaloensis, G. & R. In Buflftilo, 

 where also we take H. uniformis and H. thysbe, Mr. Eeinecke and 

 Mr. Zesch have reared Haem. buffaloensis from the egg and observed 

 it in all its stages. It makes a very slight cocoon on the surface of 

 the ground. The chrysalis has no exterior independent tongue case. 

 In its growth, as well as in the habits of the perfect moth, we see, 

 that Haemorrhagia presents resemblances to the Hesperidae, and we 

 can be sure that its Group outranks the Family. Mr. Lintner has 

 piiblished full observations on the young stages of Haem. buffiiloen- 

 sis in the interesting Reports on the State Cabinet ; the species has 

 also occurred near Albany. 



I owe to the obliging disposition of Mr. Strecker, of Reading, 

 Penn., an opportunity of examining a single specimen of H. thysbe, 

 from Pennsylvania, in which the pre-anal segments are almost 

 entirely red, with only a few lateral olive colored hairs. I think it
