NATURAL SCIENCES OP PHILADELPHIA. 247 



On tbe secondaries, in addition to the transverse row of large rounded black 

 spots above the marginal lunes, there are four connected oblique black dashes 

 helow the cell; a black mark very much like a K within and above it, and a 

 central rounded black spot within it; basal portions of both wings obscured 

 by darker shades; fringe pale yellowish cut with black; expanse,^ 1-70 

 1-75 inches 9 1*87 inches. 



Under surface : primaries pale tawny, tinged with brownish red at the base, 

 especially in the female; apical portion pale ochreous, or even yellowish 

 crossed obliquely by a brick-red shade; the markings of above repeated, but 

 faintly colored, and in the male the discal arc and central spot within the cell, 

 each contain a narrow tawny line. 



Secondaries with a broad central band of nine large connected spots, of 

 which the first, fourth and seventh are the largest, all edged on either side 

 with narrow black lines, and all with the exception of the fourth, which is 

 silvered, pale buff-yellow. The space anterior to this is brick-red, with three 

 pale yellow and one silvered spot near the base, and a yellow dot pnpilled 

 with black in the middle of the cell. The posterior half of the wing is pale 

 buff; a series of seven marginal silvery patches, surmounted by elongated 

 brownish sagittae, shading into brick-red towards the outer angle; above 

 these, a transverse row of rounded brick-red and brownish spots, the middle 

 ones usually ocellated, and there are two flexuous brick-red lines between 

 these and the central band ; a narrow black terminal line, edges the outer 

 margin of the wing3. 



Body black, covered with brownish red hairs, underneath tawny. 



Bab. California. (Coll. Tryon Reakirt.) 



It affords me much pleasure to dedicate this beautiful species to my esteemed, 

 friend, Mr. Henry B. Morris, of Burlington, N. J. 



Dr. Behr seems to have seen neither this nor the following form when he 

 prepared bis very valuable list of the " Argynnides of California." 



22. Brenthis nenoquis, nov. sp. 



Male. Fore wings slightly, hind wings much dentated. Upper surface 

 tawny; a terminal line ; a series of confluent marginal lunules also connected 

 with the bordering line ; a transverse row of large rounded black spots ; a 

 zigzag mesial band of large irregular spots and dashes, and the usual mark- 

 ings within the cell and towards tbe base of all the wings; all these, and very 

 considerable basal area, deep black ; fringe yellow, cut with black. 



Underneath the primaries are tawny, becoming pale buff-yellow on the api- 

 cal area, across which there is a violet brown shade atid on the outer margin : 

 the markings of above repeated but much diminished in size, and lightened in 

 color. 



Hind wings buff-yellow, mostly saturated with a rich violet-brown shade ; 

 a large silver spot at the base, cut by the costal vein ; two rounded yellow, or 

 silvery-yellow spots in the upper part of the cell, edged with a narrow black 

 line ; below these, two oblong velvety brown bars, one in the cell, and the 

 other in the first median area, two small rounded silvery spots on the abdomU 

 nal margin near the base, each ringed narrowly with black ; an incomplete 

 transverse maculate band of seven connected spots, of which the first, fourth 

 and seventh, are much the largest, and are always silvered, the others, very 

 rarely so ; those mentioned are always bordered anteriorly with a narrow 

 black line; and all of them posteriorly with dark violet, brown ; a submarginal 

 row of six rounded dark brown spots, the third and fourth always pupilled 

 with ochreous, the others rarely so ; seven marginal lunules, of which the six 

 superior are silvery, that on the anal angle bright yellow ; a narrow terminal 

 line edges all the wings; expanse 1-5 inches. 



Hab. California. (Coll. Tryon Reakirt.) 



Closely related to no species hitherto described ; probably is nearest to 

 Monticola, Behr, but is very much less in size, besides possessing a radically 

 different ornamentation.
