(378 ) 



rather narrow, the inner margin sliort ; liindmargin weakly roiiiidod ; scaling thin, 

 and rather glossy ; palpi short, not reaching beyond face ; antennae (cJ) with fine 

 pairs of curled cilia ; tongue present ; legs weak ; hind tibiae, as far as can be 

 seen, with only one pair of spurs. Neuration : forewings, cell half as long as 

 wing; first median nervule at four-fifths, second shortly before end, third from 

 end of cell ; lower radial from centre of discocellular, upper radial from upper 

 angle of cell : fifth subcostal from just before end of cell, curved upwards and 

 closely approximating to common stem of the next three, which run shortly into 

 costa from this common stem ; first subcostal apparently free from the base, running 

 close to the subcostal nervure as far as end of cell, and approximating to or 

 anastomosing with the stem of tlie next three beyond the cell, llindwings with 

 costal united to sulicostal by a bar near base ; two subcostals on a rather long 

 common stem; radial from centre of discocellular; medians as in forewings. 

 Type : Hemigyi anodes nitkhi sp. nov, 



Hemigymnodes nitida sp. nov. 



Wings dull grey, semitransparent, each with a pale discal spot. The forewings 

 with another slightly paler spot on the middle of the inner margin ; underside 

 the same; abdomen and legs concolorous with wings; head, face, thorax, ])ectus, 

 and base of last abdominal segment dull orange. 



Expanse of wings : 30 mm. 



Two S S from Costa Kica. 



Mimaletis gen. nov. 



Superficially very much like Alelh Jliib., but differs in the neuration, and in 

 the ? antennae. In the forewings the co.stal and first subcostal nervule are united 

 from near the base, and the ? antennae are shortly and .stoutly pictinatcd, as in 

 Terinn Wlk., not beset with fascicles of cilia. 



Type : ilivudelis poatica Wlk. (Aletis). 



Mimaletis humilis sp. nov. 



?. Forewings orange red, apical one-third black, its inner edge running from 

 just bevond the middle of costa, oblique and slightly irregular, to the anal angle, 

 forming a small blunt tooth inwards in the cell; in this apical third an obliipie 

 oblong white blotch, consisting of four oblong blotches divided by the two radials, 

 and vertically beneath it a small white spot. llindwings with hindinargin bordered 

 with black, more narrowly than in Af. postica Wlk., with five white hor.seshoe 

 shaped marginal markings ; its inner edge consists of regular curves, as in A. hclcita 

 Linn.; a small round black sjiot at end of cell, which appears much further from 

 the liindmargin than in jjostica Wlk., owing to the narrowness of the marginal 

 band. Underside like u]iper. Head, thorax, and alidomen (apparently) lilackish ; 

 but there may have been a series of white dorsal spots when fresh. 



Expanse of wings : ;)2 mm. 



One ? from the Gaboon h'iver. 



Cartaletis gen. nov. 

 Near Alelis Iliili., but (littering esix-cially in the structure of I lie J antennae, 

 which are strongly jiectinated, instead of bearing fascicles of cilia. 

 Type : Cartaletis lihyssu Hopf. {AletiK).
