transverse posterior line being narrower, more continuous, less scal- 

 loped; opposite the cell, between veins and 4, it is drawn in, forming 

 as usual a point on the intermediate vein 5. Else, while whiter, nuich 

 like its ally, the submedian dash well marked, the fringes checkered. 

 Hind wings blackish, with white fringes; tegulae black lined." 



The above is Mr. Grote's original description, but none of the charac- 

 ters hold. Nevertheless, judging from the extremely scanty material, 

 the species seems distinct by the absence of the ordinary spots and the 

 prominence of the narrow, rather sharply defined median shade line. 

 The species, if species it is, seems much less abundant than its con- 

 geners, hence it is impossible to speak of the range of variation. I 

 have seen the types only, from which the pictures have been made by 

 the courtesy of tlie oflicials of the American Museum of Natural History. 

 "California," is given as the habitat. 



MEROLONCHE URSINA, new species, 

 (riatcs X, figs. 5, 6, male :uid feiiiiile adults; XXII, iig. 22, male genitalia.) 



Dull ashen gray, very strongly powdered with blackish hair-like 

 scales, which give the insect a peculiar shaggy appearance. Head and 

 thorax without obvious markings, though the patagiae seem a little 

 dark margined and the posterior mass of thoracic vestiture is smoky. 

 Prinuiries with the markings obscure, fragmentary, and not at all 

 defined. Basal line not traceable. Transverse anterior line geminate, 

 broken, as a whole nearly upright, with tliree rather even, though 

 small, outcurves. Transverse posterior line well removed toward the 

 outer margin, with which its course is nearly parallel and only a little 

 sinuate, consisting of a series of black lunules preceded by a wliitish 

 shading. Subterminal line pale, consisting of a vague shading more 

 or less marked by dusky spots in the interspaces, sometimes not at all 

 traceable. There is a series of blackish terminal lunules, beyond wliich 

 the fringe is cut with dusky. Orbicular snuill, round or oval, con- 

 colorous, black-ringed. Eeniform small, kidney-shaped, imperfectly 

 defined by two black lunules. Secondaries whitish, jiowdery, more 

 smoky in the female. Beneath, gray, powdery, with an indefinite outer 

 line and discal si)ot on all wings. 



Expanse, 1.40 to l.GO inches (.'io to 40 mm.). 



Habitat. — Colorado. 



Several specimens of both sexes have been at hand, most of them 

 collected by JNlr. David Bruce in the mountainous districts toward 

 Glenwood, whence Dr. William Barnes has also received it. As com- 

 pared with Inpini the species has smaller, narrower, and more pointed 

 primaries and a larger, more quadrate thorax, with proportionately 

 smaller abdomen. The vestiture is more divergent and more hairy, and 

 the insect as a whole has a bluish tinge. None of the markings are 

 evident and there is only a vague indication in some specimens of a 

 median shade. The secondaries are also paler, and altogether the 

 species gives quite a different imi)ression from Ivpini. I have in the
