By the characters of the abdomen and venation it is excluded 

 from ApKoebantns and the related Epacmus and Eucessia. 



The characters of the venation are as follows : 



(1.) Second vein (R (a+ 3)) arising at the same point as the 

 third, and about 390 \x basad of discal cell. Near its end it 

 curves upwards, and ends on costa at an angle even more obtuse 

 than that presented by Pantarbes (Williston, 1. c, p. 212). 



(2.) Third vein R (4+5) robust, gently curved, with its lower 

 branch (R 5 ) forming a gently curved but nowhere angled line; 

 upper branch (R 4 ) leaving it at right angles, and after 255 /jl 

 bent at a right angle, but emitting a short vein (rudiment of 

 the cross-vein) in a straight line with the second section, so that 

 the whole branch represents a T resting on the third vein, and 

 having one of its sides prolonged and bent upwards to reach 

 the costa. The end of the branch is not bent nearly so much 

 as the end of the second vein, and its inner angle with the 

 costa is not very much greater than a right angle. In general, 

 all this is much as in Pantarbes, except as to the rudimentary 

 cross-vein directed basad (in Pantarbes the cross-vein is com- 

 plete and directed upwards). 



(3.) Radio-medial cross-vein much beyond middle of discal 

 cell (about 760 fi from its apex), and 255 \i long. 



(4.) First posterior cell open at apex, the opening about 

 120 fj, wide. 



(5.) Discal cell long and rather narrow (its length about 

 2f mm ), shaped as in Systrophus (the bounding nervure having 

 the same curves), except that it is much longer. 



(6.) Second posterior cell narrow (306 /jl) at base, and 

 extremely broad at apex (i. e. on margin) ; third posterior 

 broad at base, and narrowed apically ; fourth (morphologically 

 fifth) very broadly open, formed as in Pantarbes, but longer ; 

 its base is 476 fi from base of discal cell. 



(7.) Anal cell rather widely open. 



Alepidophora pealei sp. no v. 



Length 12 mm ; of wing 6J ; of abdomen about 8 ; width of 

 abdomen 3| mm ; head and thorax black ; abdomen dark reddish- 

 brown ; wings hyaline, nervures brown, costal region (between 

 costa and radius) reddened; as preserved, the abdominal seg- 

 ments appear as widely separated dark chitinous bands, with 

 broad colorless intervals between, these intervals being about 

 half the size of the chitinous rings. Eyes with facets of two 

 sizes, the smaller about 22 \x diameter, the larger about 42 /jl ; 

 the two kinds seem to be about equally represented, the division 

 apparently longitudinal, and not abrupt. Tarsi with scattered 

 strong bristles. Third abdominal segment slightly bristly or 

 hairy, fourth with a conspicuous patch of dark hairs on each 

 side, fifth and sixth moderately hairy, the hairs dark.
