angle. Secondaries with a band formed of squarish grey- 

 ish-white spots between the nervures, starting at the costal 

 at two-thirds the distance from the base, nearly reaching 

 the outer border in the space between subcostal and me- 

 dian, thence bent toward the inner border at a very little 

 less than a right angle, terminating at the submedian. 

 Expanse of wings, 1 1-3 in. I know this species only by a 

 single female from Conn., received from Mr. Norton. 



80. HESPERIA MONOCO nov. sp. Uniform dark-brown above 

 and beneath, the secondaries with no markings. $ Pri- 

 maries with a narrow, slightly sinuate black dash, taking 

 a general direction from the apex to the middle of the 

 inner border, commencing at the median at its second di- 

 varication and barely attaining the submedian ; there are 

 three small white or pellucid spots, one above the other, be- 

 tween the ultimate branches of the subcostal, and another 

 small one just beyond the outer tip of the black dash. 

 9 Primaries the same as the $ , except in having the 

 black dash replaced by a whitish spot, between the first 

 two branches of the median, below and a little within the 

 smaller single one. The pale markings in both sexes are 

 repeated beneath. Expanse of wings 1 1-3 in. Very 

 rare ; only in southern portions ; Conn. Mr. Norton, and 

 Mass. 



81. HESPERIA PANOQTJIN nov. sp. Above dark-brown tinged 

 with golden-yellow on the disk. Primaries more pointed 

 at the tip than in any other species ; a series of four small 

 equidistant yellowish-white spots, commencing near the 

 apex, parallel with the costal border, and terminating with 

 one larger than the rest between the earliest branches of 

 the median near the divarication ; half way between the 

 second and the costal border is a small nervure-divided 

 one. 



Beneath with no tinge of yellow. Primaries with the 

 markings of the upper surface repeated but with scarcely 

 any yellow tinge, and in addition a faint white spot near 

 the middle of the space between the median and sub- 

 median. Secondaries with a small white spot between the 

 first two branches of subcostal, three-fourths the distance 

 from the base of the wing, and a narrow pearly-white 

 streak between the next two branches, on the outer half
