witli ii fine wliitc line in frmit ; legs ochreous, externally thickly speckled with 

 olive-fnscons. 



Expanse of winjjs : 5(') mm. 



One c? from raiambii, Ecuador, November — December IbUl. 



In sliajie of wings and markings most closely ajiproacliing M. cariaria Wlk., 

 but distinguished at once by the coloration and the large black rosy-tinged anal 

 blotch of forewings. 



Mimosema gen. nov. 



Forewings: with costa curved throughout: a])ex blunt ; hindmargia curved; 

 no fovea. 



Himhvings : ample, with curved hindmargiu. 



Antennae simple, lamellate, laterally flattened. Paljii jiorrect, weak. Tongue 

 and frenulum present ; hind-tibiae simple, with four spurs. 



Neuration : forewings, cell half as long as wing ; discocellular vertical ; first 

 median nervnle at two-thirds, second shortly before end ; radials normal ; 10, 7, 8, 9, 

 stalked from before end of cell ; 11 anastomosing with 12, lU with 11 : hiudwings, 

 costal shortly approximated to subcostal ; 7 before end of cell ; no radial : medians 

 as in forewings. 



Type : Mimosema imitans sp. nov. 



1','7. Mimosema imitans sp. nov. 



Forewings: red-brown, freckled with black; the costa darker towards base; 

 lines deep red, straight ; first from one-third of costa to two-fifths of inner margin ; 

 second from four-fifths of costa to two-thirds of inner margin, the first preceded, the 

 second followed, by a pale line ; traces of a subterminal line indicated by dark spots 

 on veins ; fringe concolorous ; cell-sjjot dark, indistinct, preceded by a dark spot 

 towards upper margin of cell. 



Iliiulwings : without inner line ; the outer from three-fonrths of costa to anal 

 angle ; cell-spot and submargiual line indistinct. 



Underside [learl grey ; outer line marked in both wings ; marginal area witli 

 a rufous cloud ; apex of both wings whiter with dark speckles ; cell-spots more 

 distinct ; fringe rufons ; head, thorax, and abdomen concolorous with wings, but 

 the face and palpi deeper tinged, the abdomen paler, especially the anal segment. 



Expanse of wings : 30 mm. 



One c? from Chiriqni, Panama. 



There is much superficial resemblance between this insect and one or two 

 species of the genus Dichromatopodia on the one hand and Sgrrkizodes deludens 

 Warr. on the other. From I he former the ueuratiou at once separates it; from 

 the latter it is distinguished by the simj)le instead of pectinated antennae, and the 

 difi'erent subcostal neuration of forewings. The absence of a fovea in forewings, 

 besides other points, prevents its inclusiou in either ilicroxydia or Cartellodes, 

 with which it agrees in the simple antennae. 



128. Nematocampa benescripta sji. nov. 



Forewings : bright ochraceous with deeper ochraceous specklings ; costa and 



hindmargin narrowly black-brown ; the lines of the same colour ; first slightly 



sinuous from one-third of costa to one-third of inner margin, incurved below middle ; 



second from two-thirds of costa to three-fourths of inner margin, thickened and
