2 GROTE AND ROBINSON. 



to the two other dots the apex of an oblique triangle, which might be 

 drawn so as to include all these maculations ; apieally, the wings are 

 dull blackish ; fringes, pale, stained with darker shades below the apex 

 and interruptedly so at the middle ; posterior wings, resembling prima- 

 ries in coloration, immaculate, slightly produced at anal angle; fringes, 

 pale, immaculate. 



Under surface of wings, dull olivaceous blackish, with lilac and 

 brown shades. Anterior pair bright brown along costa and more dif- 

 fusely so towards the apex ; the white dots of the upper surface are 

 here reproduced, surmounted by three short, oblique, costal pale marks, 

 but they are larger, more nearly one sized and sub-quadrate ; a lilac 

 shade, deepening inwardly inferiorly to purplish, spreads terminally 

 from apex to about 2nd median nervule ; fringes as on upper surface, 

 but more prominently interrupted with darker scales at the extremity- 

 of the nervules. Secondaries, dull obscure brownish, somewhat oliva- 

 ceous along internal margin, and obsoletely shaded with light purple 

 at the middle ; a faint, extra mesial, arcuate band of disconnected in- 

 terspaceal, pale discolorous blotches, which are discontinued within in- 

 ternal margin, and most prominent at the bases of the median nervule; 

 u terminal lilac shade much as on anterior wings ; a terminate narrow 

 dark line ; fringes, pale, obsoletely interrupted with dark scales at the 

 extremities of the nervules. 



Expanse, 1.50 inch. Length of hoJi/, 0.70 inch. 



Habitat. — Atlantic District. (Georgia!) 



This species bears a slight resemblance to Eudamus bathyllus, Bilv. 

 and Lcc, in coloration. It is structurally distinct in the shorter an- 

 tennae, wanting the prominent reflection of Eudamus, narrower prima- 

 ries, and by having the abdomen as long as the internal m:irgin of the 

 secondaries. We have examined two male specimens, taken by Mr. 

 James Ridings, in Georgia, during the early summer of 18GG, 



Hesperia fasca, n. sp. 



]\lah>. — lluad, thorax and abdomen, above, olivaceous blackish ; the 

 prothoracic scales are shaded with golden brown, which latter shade 

 extends narrowly above the eyes and liuearily across the front and 

 strongly tinges the terminal palpal hairs. Beneath, the palpal scales 

 are yellowish-white, which latter color extends narrowly below the 

 eyes; the thoracic scales are pale yellowish olivaceous ; the al)domen 

 is shaded with obscure whitish. Antenmo, moderate, slender; the an- 

 tcnnal stem, above, is fuscous, beneath, annulated witli yellowish-white. 

 which latter shade extends over the "club" at base, the latter mode-
