This is clear and there can be no sort of doubt of the character of 

 the variation which Mr. Grote intended to name. I have seen just 

 this sort of change in other species, but not in pudens. During the 

 year or two last past, Mr. H. D. Merrick, of New Brighton, Pennsyl- 

 vania, has taken a considerable number of specimens, to which, in 

 some way, the name aiiticosticnsis came to be applied. It differs from 

 the type form in lacking the pink shades entirely, and in having the 

 normal maculation more complete and more clearly written. The 

 ground color is also richer and more intense than in the type form, so 

 that, when 1 had only a single specimen I strongly suspected a new 

 species. Mr. Merrick has taken so many examples however, in com- 

 pany with the normal form and under conditions which convinced him 

 that copulation between the two had taken place, that the relation be- 

 tween the two remains hardly doubtful. It is certainly a strongly 

 marked departure from the type and therefore entitled to a varietal 

 name which I derive from the locality. It is of course probable that 

 the same form occurs elsewhere, but its local abundance at this point 

 deserves recognition. 



Dates of capture range from April 29th to May 5th, and the species 

 is thus an early flier. 



Cyathissa pallida, sp. nov. 



Ground color white with a faint creamy tinge. Head and thorax concolorous, the 

 posterior thoracic tuft tipped with pale rusty brown. A short rusty basal streak, em- 

 phasized by a few black scales ; but not prominent. Basal line marked by a few rusiy 

 costal scales only. T. a. line geminate, incomplete, rusty luteous, a little angulated 

 below the cell, then almost evenly oblique to the inner margin : in the submedian in- 

 terspace the inner line is emphasized by black scales. S. t. line not defined. The 

 ordinary spots are not defined. The upper half of the median space is pale slate 

 gray, and out of this shade is cut a large oblong white spot, extending from costa into 

 the median cell and well defined by darker scales. A slaty gray shading also extends 

 through the s. t. space, narrowly bordering the t. p. line to the angle, where the 

 shade expands and extends to the anal angle, leaving free a semicircular area on the 

 inner margin beyond the t. p. line : this area is faintly yellow-tinged. There is also 

 a vague slaty shading within the excised outer margin below apex. Secondaries 

 white, immaculate. Beneath white, with a vague creamy tinge along the costal area.

Habitat. — Walters Station, California, in April (George S. 

 Hutson). 



Has the peculiar pallid desert appearance and is represented by 

 one good female. It seems to be fully congeneric with the Texan 

 percara and the type of maculation is identical ; but this is a larger
