 it out and rising to the surface, may be captured. 



Amblychila cylindriformis, Say. Dr. Horn described, 

 Trans. Am. Ent. Soc. vol. VII. p. 29, pi. II., the larva, dug out by 

 Mr. E. W. Guild in Kansas from borrows of 14 inches to 8 ft. deep, 

 in dry, clayey banks. 



Color yellowish white, head and prothoracic scute castaneous. 

 44 mm. long, 6-7.5 mm. thick. Eyes one on each side. Spiracles 

 9 pairs, the first and largest under the margin of the prothorax. 



Omus Dejeanii, Reiche. Dr. Horn, 1. c. p. 31. Color yellow- 

 ish white, head piceous, prothoracic scute pale castaneous. Length 

 in normal flexed position (see fig.) 20 mm. width 4 mm., (per- 

 haps not fully grown). Eyes four on each side, two larger and 

 two smaller. Spiracles as in Amblychila. 



Tetracha Carolina. Lin. Dr. Horn, 1. c. p. 34. Color yel-

 margin of the latter testaceous. Length 17 mm. Eyes four on

NOTES ON 



Notodonta Tremula, Clerck, N. Dictaeoides, Esp., and 



N. Rimosa, Pack. 



Referring to the article in the Entomological Contributions by Mr. J. A. 

 Lintner (Report of the New York State Museum of Natural History, 1S78, p. 

 76.) on Notodonta Dictaea, Linn., I beg to offer the following. According t<> 

 Dr. O. Staudinger (see his Catalogue, p. 72 and 73.) there are two distinct 

 species in Europe, Notodonta Tremula, Clerck (Dictaja (L.) Esper) and Noto- 

 donta Dictaeoides, Esper. They are closely connected, but present differen- 

 ces by which they can he distinguished. The male of Tremula has the an- 

 tennae stronger and more heavily pectinated than Dictaeoides; in the speci- 

 mens I have seen the brown shadings are of a richer color in Dictaeoides; 

 the white lines on the veins near the exterior margin of the primaries are 

 Longer in Tremula, while the white streak near the inner angle of primaries is 

 wider, of a clearer color, and consequently more conspicuous in Dictaeoides, 

 and the secondaries of this species are rather darker than in Tremula. Our 

 American congener, Notodonta (Pheosia) Mimosa, Pack., would seem to stand 

 between the two, the markings bearing closer resemblance to those of Tremu- 

 la, while the antenna! structure of the male conforms more to that of Dictae- 

 oides. 



The three species certainly preseut a similarity remarkable in the entomo- 

 logical relations of the two countries, and as I was rather puzzled what to
