band which extends inward half way between the costa and interior 

 margin. A large subapical patch only partially separated from the 

 broad exterior marginal band by a broken irregular patch of the 

 paler ground color, this marginal band encloses a paler semi-band 

 on the inner half, and a row of pale lunate spots on the margin 

 which are largest at the anal angle and become smaller and more 

 indistinct the nearer they approach the apex. All the dark spots, 

 etc., are margined with a lighter color. In the centre of the sub- 

 apical patch is a small round silver dot, on the marginal band inte- 

 rior to the latter two very small silver marks. 



Secondaries almost uniform smoky gray, darker toward apex near 

 which, touching outwardly on the costa, is a pale elongate mark. A 

 row of indistinct lunules at exterior margin. 



Expands nearly 4 inches. Taken near Bangor, Maine. 



This differs from other known North American species which I 

 here diagnose. 



Hepialus argenteomaculatus Harris, Cat. Ins. Mass., p. 72, 1864. 



A pale olivaceous species with darker bands, etc., inclining in part 

 to a golden tinge, occurring from Maine to Wisconsin, and in 

 Canada.

I know only by the description which leaves little doubt but that 

 it was founded on a dark example of the preceding. 



H. quadriguttatus Grote, 1. c, p. 73, t. 1, f. 6, 1864. 



The large yellowish salmon colored species found in Maine and New 

 Hampshire. In Can. Ent.,Vol. XXV, p. 124, 1893, it has been claimed 

 that this insect was never really described and that Quadrigut- 

 tatus is synonymical with argenteomaculatus. On this assumption it 

 was there described as argent, var. semiauratus n. v. but on looking 

 carefully at Grote's description it will be seen that it fits the salmon 

 colored species at least as well as the other and his figure undoubtedly 

 represents that one. His description says plainly " Posterior 

 wings entirely pale salmon color " etc. " Abdomen pale salmon 

 color " ; etc. " Under surface of both wings tinged with salmon 

 color." Now none of this applies to argenteomaculatus which has 

 grayish or pale ochraceous brown posterior wings and abdomen, and 

 whose under surface is also ochraceous or brown, varying in depth 

 of color in different examples but entirely destitute of any indica- 

 tion of the fleshy red tint known as salmon-color — from this it seems
