88 Mr. A. G. Butler on Heterocerous Lepidoptera 



A species of the family Hepialidce has been described 

 by Berg in the ' Anales de la Sociedad Cientifica Argen- 

 tina ' for 1882 (April to June), p. 30, n. 31, under the 

 name of Mpytim dimidiatus, from Chili ; it appears to 

 be a large and fresh male of my Dalaca hemileuca, of 

 which it will in that case be a synonym. 



Five other Geometers must be also added to Mr. Ed- 

 monds' captures : — 



An apparently new genus of Macariida, which at 

 present I hesitate to name owing to its imperfect con- 

 dition ; it is a pretty silvery-white species, the primaries 

 crossed by an ill-defined angulated darker band, black- 

 edged towards costa, and enclosing two orange spots. It 

 was obtained from Keed's collection, and was probably 

 captured in Valdivia. 



The second species is an Yjjsipetes, very aberrant in 

 colouring, and which, therefore, puzzled me greatly. 



Ypsipetes chiloensis, n. s. 



Primaries above sandy yellow, sparsely speckled with 

 black, and traversed by two series of black spots indi- 

 cating the limits of the ordinary central belt ; a third 

 series upon the outer margin ; an oblique blackish dash 

 just above the middle of the external area ; fringe spotted 

 with blackish ; secondaries much whiter than the pri- 

 maries, but still of a pale sandy yellow tint irrorated 

 with grey ; an oblique grey dash across the abdominal 

 area beyond the middle ; a marginal series of depressed 

 blackish spots ; body coloured in accordance with the 

 wings, the thorax being darker than the abdomen ; pri- 

 maries below washed with smoky grey, excepting at the 

 borders, which are black-speckled ; only the outer series 

 of black spots visible ; an additional black spot at the 

 end of the cell ; secondaries cream-coloured, irrorated 

 with brown ; a small blackish disco-cellular spot and a 

 zigzag discal line ; body below cream-coloured ; legs 

 irrorated with greyish. Expanse of wings, 35 mm.

There are also two very worn specimens from the 

 Cauquenes of what probably represent a new species of 

 Selidosema : they are not good enough to describe. With 

 the latter I found associated four examples of what I
