SmileumA; gen. nov. 



Face rounded-prominent, apparently not tufted (more or 

 less abraded in all available sjx'cimens). Palpus short 

 ( }jt(i(/ifracfa) or rather short (salcd'tza), quite nuMlerately 

 rou^rh-sealed. Antenna in ^ lamellate, nearly simple. 

 Hind tibia with all spurs. Abdomen not crested. Fore wing 

 triangular, apex moderately acute, termcn strongly oblique, 

 as long as inner margin ; cell Ict-s than one-half, discoccllulars 

 incurved, oblitjue below, SC- arising out of SC^, anastomosing 

 with SC^* "' beyond SC^ (further beyond in play'ifractu) to 

 form a broad simj)le areole ; R^ connate with SC'"^ ; M' 

 separate from R-'. Hind wing witli termen not very strongly 

 convex, apex therefore slightly but roundly produced; cell 

 short, little over one-third, discoccllulars not biangulate, 

 oblique below, SC^ rather long-stalked, with R', R- from 

 middle of DC, M' separate from R^. Scaling very glossy.

 Ent. Relg. xxxvii. p. 575 (Cidaria). 



Nearly related to the preceding genus, distinguished by 

 the simple areole. On Meyriek's tabulations it would fall 

 into the Pala'arctic Pliiiitjria as used by that author { = Ple- 

 ntyri(i + E])irrlio'('+ Eiilyitt'+Trichodez'ui) and stated by him 

 to be numerous in South America. It has most in common 

 with Plemyria, sens. str. (type, bicolurata, Hufn.), and Epir- 

 rho'e (type, ulternata, Mull., = 50cia/a, Jiork.), but they both 

 have the cell of fore wing normal (one-half), the palpus 

 stronger, the sliape of wings and several details of venation 

 different ; wliile some characters which are not usually 

 regarded as generic — the smooth glossy scaling and the 

 diti'crcnt type of pattern — probably point to a wider evolu- 

 tionary divergence.
