246 THE CANADIAN ENTOMOLOGIST. 



terminal joint of the palpi is nearly as long as the second, recurved ; 

 tongue rather scantily and roughly scaled at the base, the scales laterally 

 projecting. Having but a single specimen, I have not examined the- 

 neuration, but the palpi are nearly those of N. vecharceUa, as figured in 

 Ills. Brit., V. J, than to any other genus known to me. 



Pale gray ; basal half of the second joint of the palpi dark brown on 

 the outer surface ; tip of third joint dark brown ; basal joint and annu- 

 lations of the stalk of the antennae brown. There is a rather short dark 

 brown line on each side of the thorax above the wings. Primaries with 

 the extreme costa at the base, and the inner angle, dark brown, and the 

 base towards the dorsal margin suffused with faint reddish yellow ; the 

 disc from the base nearly to the middle is suffused with brown, and there 

 are faint brownish streaks between the veins in the apical part of the 

 wing. Al. ex. Vj^ inch. 



HOLOCERA. 



H. Clemensella. N. sp. 



H. chalcofrontella Clem, is so variable a species that it is possible this^ 

 may be a variety of it j but it is not one of the described varieties. 



Whitish, dusted lightly with dark purplish brown, the dusting dense on 

 the second joint of the palpi. There is a purplish brown patch at the 

 base of the costa, a small one about the middle of the costa, a small one 

 opposite to it on the fold, a small one on the disc opposite the space 

 between the other two, one at the end of the disc, and a row of small 

 dots around the apex at the base of the ciliae. AL ex. ^ inch. Season 

 August. 



POLYHYMNO, ge]L HOV. 



The two insects for which I erect this genus are possibly not con- 

 generic. P. luteostrigella is a slender, elongate insect, whilst P. sexstrigella 

 is rather robust ; there is but a single specimen of the latter species, and 

 the head of that is wanting, though it is otherwise perfect. The forni and 

 neuration of the secondaries is very nearly the same in both, and so is the 

 form of the primaries, except that those of sexstrigella are a little wider. 

 The generic diagnosis is that of luteostrigella. The points in which 

 sexstrigella differ from it are noticed under that species. The form of 

 luteostrigella and the markings of the wings in both species are suggestive
