Miantonota Warr., Nov. Zool. II. jj. 89. 



In the description of this genns the t? was stated to have lint one terminal 

 spnr on the hind-tibiae. I am now of opinion that the example from which the 

 description was drawn was malformed or damaged. The hind-tibiae are thickened, 

 armed internally with a pencil of hairs, and externally with a process extending 

 beyond the end of tibia, with two pairs of short spnrs. 



The species described as Rachcospila rcmota (Nov. Zool. VII. p. 139) should 

 be transferred to Miantonota, the abdomen being without either the dorsal spots or 

 crests of Racheospila Gnen. and Rackeolopha Warr., but differing from the type- 

 species Miantonota integra in having the abdomen wholly green, without the three 

 red segments. 



Neocrasis gen. nov. 



Forewings : costa curved at base and towards apex, straight between ; hind- 

 margin with a strong tooth at vein 4 and a small one at vein 7, strongly concave 

 between the teeth, obliipie and slightly concave between 4 and anal angle, which is 

 well marked. 



Hindwings : kite-shaped ; the hindmargin produced into a strong tooth at 

 vein 4, the margin above and below nearly straight ; both apical and anal angles 

 well marked ; antennae (<?) bipectinated ; palpi porrect, stout ; basal joint hairy, 

 second less so, third short, blunt ; tongue and frenulum present ; hindlegs broken 

 off ; abdomen without tufts. 



JSexration : forewings, cell two-fifths of wing : discocellular strongly incurved 

 at middle ; first median nervule just beyond middle, second close to third ; vein 5 

 from upper third of discocellular : 6 from upper angle of cell, whence also the 

 common stem of 7, 8, 9, 10 ; 11 free. Hindwings, 3, 4, and 6, 7 very shortly stalked, 

 the rest as in forewings. 



Type : Neocrasis obscurata sp. nov. 



33. Neocrasis obscurata sp. nov. 



Forewings : dull dark green ; the costal edge yellow, with purplish striae ; 

 lines marked by white dots on the veins, the central space being deeper green along 

 the lines ; the onter line angled on veins 4 and C ; cell-spot deep green ; marginal 

 line deep green, interrupted at the vein ends ; fringe pale green, chequered with 

 dark at apex, at tiie two teeth, and at anal angle. 



Hindwings : similar, without first line, and with the costal edge green. 



Underside clondy greyish green ; both wings with a broad smoky blackish 

 marginal fascia, complete in the hindwings from apex to anal angle, 'in the forewings 

 fading ont towards costa ; costal edge of forewings broadly yellow throughout, of 

 hindwings with some dark scales at middle ; cell-spots, marginal line, and chequering 

 of fringe blackish. Face and palpi yellow-green ; head, thorax, and abdomen dull 

 green, the abdomen becoming yellower ; forelegs with femora and tibiae yellowish, 

 the tarsi blackish. 



Expanse of wings : 27 mm. 



One c? from Colombia. 



Unlike any other South American insect of the subfamily.
