best marked l^y the black filling between them. There is a broken smoky line at the 

 base of the fringes. Secondaries smoky fuscous with a vague trace of a median line. 

 Beneath, fringes powdered ; both wings with an outer line which is barely traceable 

 on the fore wings ; the hind wings with a discal spot. Expanse, 1. 40 inches = 35 mm. 



Habitat: Garfield County, Colo., 6,000 feet. (Bruce.) 

 I have two female specimens under examination and believe that I 

 have seen others. The species is a very distinct one by the markings ; 

 the black -filled spaces between the ordinary spots and the connected 

 median lines being quite characteristic. Unfortunately no male is at 

 hand, and it is not impossible that the species may have to be trans- 

 ferred to Ma)nestra. The vestiture consists of flattened hair and in 

 the poorer specimen of the two there is a distinct indication of ab- 

 dominal tufts. The wing form, however, is of the usual type found in. 

 this genus and more triangular than in most species of Maiiicstra. 



Scotogramma infuscata, sp. nov. 



(iround color a very dark smoky yellow, strongly black powdered. Head and 

 thorax a little more evenly smoky in color. Primaries with all the markings black 

 and fairly distinct. Basal line distinct, single, black, twice toothed. T. a. line 

 irregular, black, almost upright in general course, irregularly toothed to below the 

 median vein and then with a strong inward tooth on the submedian vein. T. p. line 

 black, lunulate, single, very nearly parallel with the outer margin. There is a some- 

 what indefined, broad, smoky, median shade, which is bent over the reniform and 

 below that point runs close to and parallel with the t. p. line. S. t. line marked by 

 a smoky preceding shade in which are darker, almost blackish blotches, which em- 

 phasize this .shade as against the very even and uniform terminal space. There is a 

 broken terminal, dusky line and the fringes have also a dusky interline. Orbicular 

 round, small, outlined by blackish scales. The reniform is vague, hardly traceable in 

 fact in most of the specimens ; but sometimes fairly evident as a narrow upright shad" 

 ing. Secondaries smoky fuscous, dusky outwardly, with a vague median line and a 

 faintly marked discal lunule. The fringes are yellow. Beneath, very strongly pow- 

 dered with yellow-, with a well-marked smoky extra-median line, a broad outer margin 

 and a discal lunule. Expanse, 1.25 to 1.45 inches = 23 to 36 mm. 



Habitat: Colorado, Park County, 10,000 feet, July 9th; 13,000 

 feet, July 6th; Gibson Mountain, 12,500 feet. 



One male and three females, all collected by Mr. Bruce. The in- 

 sect has almost exactly the same markings that are found in the species 

 previously described and the vestiture is also fine and hairy ; but the 

 colors are all very much darker and the insect has quite a different 

 habitus. Mr. Bruce's number is 646. 

 Scotogramma discolor, sp. nov. 



Llround color dull gray over a somewhat luteous base. Head and thorax much 

 paler, the hair being quite distinctly yellowish and the anal tuft of the abdomen is 

 also yellowish. Primaries with the basal space yellowi.sh, owing to an admixture of
