2 ? ? from R. Hnacamayo, Carabaya, Peru, taken at, the same time and height 

 as the type-specimen (Ockenden). 



In some of the ? ?, both of type and aberration, the underside of the hindwing 

 shows traces of a pale curved middle baud with some fulvous striae. 



Mesobomba gen. nov. 



Forewing : costa straight, strongly convex at apex, which is depressed and 

 bluntly produced ; outer margin strongly sinuate, gibbous between 2 and 4, and 

 insinuate beyond each fold ; anal angle distinct. 



Hindwing : with outer margin at middle strongly gibbons with a sinus on each 

 side ; antennae of ? simply pubescent ; tongue and frenulum present ; palpi short ; 

 hiudtibiae with four spurs. 



Nenration : forewing, cell less than half of wing ; discocellular, apparently, 

 vertical; first median nervule close to end of cell, second and third stalked; the 

 two radials close together from upper end of cell; 7, 8, 9, 10 stalked ; 11 anasto- 

 mosing, and becoming coincident with 12 : hindwing, costal and subcostal 

 anastomosing for three-fourths of cell ; 3, 4, and 6, 7 stalked; no radial. 



Type : Mesobomba J/ai:i fascia spec. nov. 



The type-species is not at all unlike the description of Pkaludia Janeiro, Schaus, 

 from Rio Janeiro, which I have not seen ; but the diagnosis of the genus does not 

 tally at all. 



260. Mesobomba flavifascia spec. nov. 



Forewing : violaceous purple ; the markings broad and diffuse, deep brown- 

 black ; basal area purplish, containing a deeper curved inner line, running in 

 towards base of inner margin ; a diffuse pale yellowish fascia across middle of wing 

 with some dark striae on its outer edge, forming a kind of outer line ; a broad 

 submargiiial dark fascia, edged in parts with ochreous scales; marginal line and 

 fringe dark pnrjile. 



Hindwing : with the three bands more distinct ; some yellowish scales between 

 first and second. 



Underside dull brownish purple ; the yellow fasciae clear ; that of forewing 

 broad at costa and quite narrow on inner margin ; that of hindwing constricted in 

 middle; base of hindwing yellow. 



Face and collar yellowish ; head and thorax purplish ; abdomen missing. 



Expanse of wings : 19 mm.

 wet season (Ockenden). 



Pygmaeopsis gen. nov. 



Forewing : elongate-triangular ; costa straight ; apex depressed, bluntly 

 ronnded ; outer margin obliquely curved ; anal angle distinct. 



Hi n<l wing : small; outer margin ronnded; anal angle square; inner margin 

 incurved and slightly furrowed. 



Antennae quite three-fourths as long as forewing, thick, pubescent ; palpi 

 short, porrect ; tongue and frenulum present ; hiudtibiae thickened, with four spurs. 



Neuratinn : forewing, cell quite half as long as wing; discocellular vertical ; 

 first median nervule at five-eighths, second close before third ; lower radial from 

 above centre of discocellular, upper from npper end of cell; 7, 8, 9, in, 11 stalked
