1891.] MICRO-LEriDOl'TERA OF THE WEST INDIES. 503 



Cacocharis, gen. n. 



(KctKo^apis = ill-omened . ) 



Type, c? 2 Cacocharis albimacula, Wlsm. (Plate XLI. fig. 4, 

 «, b.) 



Antennce not more than half the length of the fore wings, simple 

 in both sexes. 



Palpi placed rather wide apart, short, projecting but little beyond 

 the head ; second joint somewhat dilated at the apex above and 

 beneath ; apical joint short, distinct. 



Head moderately crested above. 



Thorax with a strong erect crest posteriorly. 



Fore wings rather ovate, costal margin slightly arched, c? without 

 a costal fold, apex obtuse, apical margin not indented nor oblique, 

 anal angle rounded. Nenration : 12 veins, all separate; 3 bent up 

 towards 4 on the apical margin ; 6 slightly bent down towards 5. 



Hind wings trapezoidal, apex rounded, somewhat bulged between 

 the apical and dorsal margins. Neuration : 8 veins ; 3 straight, 4 

 from the same point as 3, bent upwards towards 5 on its basal half; 

 5 closely approximate to 4 at the base. 



Legs with the hind tibiae stout, somewhat clothed. 



This genus is intermediate between Pcedisca, Tr., and Penthina, 

 Tr., approaching the latter in the possession of a thoracic tuft and 

 in having veins 3 and 4 of the hind wings from a point ; in all 

 other respects it belongs to the group of Pcedisca, but is without a 

 costal fold. 



Cacocharis albimacula, sp. n. 



Antennce and palpi reddish brown. 



Head reddish brown. 



Thorax reddish brown, with a conspicuous bright chestnut tuft 

 posteriorly, preceded and followed by some whitish scales. 



Fore wi^gs rich chestnut-brown, with a conspicuous white costal 

 patch about the middle of the wing, containing two or three minute 

 black streaklets on the extreme costal margin ; mottled with fuscous 

 and purplish-grey patches ; the white costal patch is preceded and 

 followed by a fuscous tinge; a brownish patch lies on the outer half 

 of the fold, and a blackish patch of somewhat raised scales near the 

 base of the dorsal margin is surrounded by purplish grey ; about 

 the outer end of the brown patch is another space of purplish grey, 

 and between this and the apical margin another transverse patch of 

 the same colour, somewhat paler ; one or two very faint pale oblique 

 streaklets, from the costa before the apex, are joined to a slender 

 pale line along the margin at the base of the cilia, which, however, 

 does not reach tbe anal angle; cilia brown, tipped with fuscous. 



Hind wings fuscous, with an iridescent tinge ; cilia fuscous. 



Abdomen fuscous. 



Legs pale greyish cinereous ; hind tarsal joints spotted with 

 fuscous.
