basal black streak. T. a. line visible only in the s. t. interspace, where 

 it crosses the black basal dash in the form of an outcurved pale line 

 margined with deep black. T. p. line narrow, siugle, finely creuulated, 

 slightly outcurved over reuiform, thence very evenly parallel with the 

 outer margin. This in the 9 ; in the $ no trace of the line is visible. 

 In the $ the color is even unbroken through the median and s. t. space 

 to the s. t. line, which arises from a gray apical spot and is punctiform 

 and very slightly irregular, the spots preceded by sagittate black dashes 5 

 beyond this line the narrow terminal space is slightly more dusky, and 

 there is a row of suiall black terminal dots; in the 9 a grayish suffu- 

 sion along the black marked veins relieves and lightens the s. t. space, 

 intensifies the black sagittate dashes and makes the terminal space 

 darker by contrast; the maculation, otherwise, is as in the 5 , save that 

 the 8. t. line is more evident and some of the spots are connected, showing 

 that the line is distinctly dentate on veins 3 and 4. Chiviform distinctly 

 black margined, variable in size and form, center concolorous, sur- 

 mounted with an also variable pale yellowish streak crossing the 

 median space. Orbicular oval, oblique, complete, black ringed, then 

 with a pale aunulus, center of the color of costal region ; reniform large, 

 kidney shaped, contrasting yellowish, inferiorly dark grayish marked. 

 In the 9 the entire internal margin is gray marked. Secondaries 

 evenly fuscous, with a row of terminal darker lunules, fringes paler. 



Expands 41-45"''"; 1.G5-1.80 inches. 



Habitat. — California (Neuraoegen). 



This handsome and well-marked species comes nearest to oheliscoides 

 in the tessellata group, but is perhaps as nearly allied to perexcellens 

 of the quadridentata group. From the latter it is distinct by the lack of 

 the prominent dentations of the s. t. line; from the former by its very 

 much larger size, the more produced primaries, different s. t. line, and 

 other details of maculation. The line of variation is in the same direc- 

 tion as in perexcellens, the specimens before me showing strong differ- 

 ences, while evidently referring to the same species. 



Since the above was written I have seen a series in the U. S. National 

 Museum, which runs from the form above described to a uniform black, 

 the maculation scarcely identifiable. 



Carueades islandica Stgr. 

 1857. Stgr., Stett. Eut. Zeit., 1857, 232, Jgrotis. 



Dull luteous, median and terminal space darker, cell black, costa and 

 large ordinary spots concolorous with palest colors of ijrimaries. T. a. 

 line obsoletely geminate, not crossing costa, straight to vein 1, out- 

 wardly curved below. T. p. line evenly oblique from cell to hind mar- 

 gin, crenulate. S. t. line very indefinitely marked by the contrast 

 between s. t. and terminal spaces. Claviform distinct, dark. Ordinary 

 spots essentially as in oheliscoides. Secondaries fuscous. Beneath
