a 2 . Wings not so narrow, the width one-sixth the length or more; first and third 

 antenodal costal spaces about equal, the first less than twice the second; dis- 

 tance from base to nodus one-third the wing length or slightly less. 

 b 1 . R s arising at the subnodus, M 3 proximal; Cu x produced beyond the cross vein 



descending from the subnodus Epipleoneura. 1 



c 1 . M 2 arising at the third postnodal in the hind wings. 

 d 1 . M 2 arising at the fourth postnodal in the front wings; the second antenodal 



costal space shorter than the other two „ incusa. 



d 2 . M 2 arising at the fifth or distal to the fourth postnodal in the front wings, 



the 3 antenodal costal spaces subequal .fuscaenea, 



<?. M 2 arising midway between the third and fourth or proximal to the fourth 

 postnodal in the hind wings, at the fifth or more distal in the front wings, 



the second antenodal costal space shorter than the other two lamina. 



b 2 . R s arising distal to the subnodus, M 3 proximal, at or distal to the subnodus, or 

 R s and M 3 joined at their origin into a single vein arising at or distal to the 

 subnodus. 

 c 1 . Guj ending at the cross vein descending from the subnodus, the three ante- 

 nodal costal spaces about equal Psaironeura. 



d 1 . Dorsum of thorax and last abdominal segments with much red or yellow. 

 e 1 . Superior appendages of the male subcylindrical, the inferiors terminated 



by a small, blunt, curved point tenuissima. 2 



e 2 . Superior appendages of the male forked, the inferiors without a point. 



cerasina. 



d 2 . Dorsum of the thorax and last abdominal segments with little or no red or 



yellow. 



e 1 . Abdomen of female 31 mm., 8 and 9 black; hind wing 19-20 mm . . remissa. 



e 2 . Abdomen of female 26 mm., 8 and 9 with basal articulations and the apex 



of 9 pale; hind wing 19 mm sancta. 3 



c 2 . Guj produced beyond the cross vein descending from the subnodus; M 2 

 arising at the fifth postnodal in the front wings, at the third or proximal 

 to the fourth in the hind wings; first and third antenodal costal spaces 

 about equal, the second much shorter, but more than one-half the third; 

 stigma long and narrow, more than twice as long as wide. 



Epipotoneura nehalennia. 



The discussion of various species collected follows. 



PROTONEURA CALVERTI, new species. 



Length of abdtfmen, male 32-34 mm., female 27-29; hind wing, 

 male 17.5-18.5 mm., female 18-19. 



Head. — Male. Shining black; labium pale flesh colored; genae 

 bright yellow ; 4 duller yellow spots across the head, 1 at the base of 

 each antenna, and 2 on the frons in front; rear of head black. 



Female. Black; dorsum with metallic green and violet reflec- 

 tions; labium pale flesh; genae almost white, greenish tinged; ante- 

 clypeus with 3 pale spots, obscure or wanting; 4 spots across the 

 head as in the male, but larger and clear pale yellow.

2 Tenuissima Selys from the Amazon is known to me only from description; both sexes are known. In 

 coloration it is scarcely distinguishable from cerasina. 



3 Only the female of sancta Hagen from Brazil is known, and this to me only from descriptions.
