Subfamily GEOMETRINAE. 

 30. Auophylla basiplaga spec. nov. 



Forewing : pale green, with bone-coloured markings edged and speckled with 

 dull red ; the line edging the marginal pale area starts from costa shortly before 

 apex, is roundly curved outwards between 7 and 4, below which vein it nearly 

 reaches outer margin, forming a shallow curve to above vein 2, then running 

 iuwards and touching 2, whence it curves upwards and forms a quadrate projection 

 above vein 4 touching discucellular, thence descending again vertically and slightly 

 waved to middle of inner margin ; close to base of inner margin is a small 

 semicircular patch of bone-colour, edged with red; marginal line red; fringe 

 bone-colour. 



Hinchving : similar, but the costal blotch is larger, and that at anal angle 

 smaller; the blotch at base is likewise larger than in forewing; a white spot on 

 upper end of discocellular. 



Underside very pale green, with the white areas showing through. 



Head, thorax, and abdomen pale green, the dorsum with a series of red crests. 



Expanse of wings : 24 mm. 



1 3 from Sapncay, Paraguay, July 1902 (Foster). 



Close to A. multiplagiata Warr. from Paraguay. 



37. Blechroma oppleta spec. nov. 



S. Forewing: pale green, with all the grey-brown bands and shadings of 

 confusa Warr. so largely developed and amalgamated that only four small patches 

 of green remain : viz. two small triangular patches on inner margin on each 

 side of the end of outer band, one on costa at one-third, and a larger one on 

 outer margin below apex ; the course of the dark curved basal band and of the 

 outer and submargiual bands can be traced by the paler-edged lines, aud the 

 cell-spot is blackish aud distinct; marginal line formed of coalescent purplish 

 black lunules ; fringe grey with a whitish base, aud faint checpaering. 



Hindwing : green, with base narrowly dark brown ; a curved grey band just 

 before middle, and the whole outer two-fifths grey-brown, containing a paler 

 lunulate-dentate outer line, with the teeth marked prominently on the veins ; 

 margin from 4 to 6 narrowly green ; marginal line fine, blackish. 



In the ? all the green spaces are larger, but in no case to such a degree that 

 the insect can be mistaken for confusa Warr. 



Underside paler green, with all the grey-brown areas duller. 



Head aud thorax grey-brown ; basal segment of abdomen with a velvety 

 black ring ; rest of abdomen ochreous above, whitish below ; shoulders green. 



Expanse of wings : $ 32 mm. ; ?.39 mm. 



1 S, 1 ? from La Oroya, R. Inambari, Peru, 3100 ft., September 1904, dry 

 season, and 1 <? from R. Hnacamayo, Carabaya, Pern, 3100 ft., June 1904, dry 

 season (Ockenden). 



38. Comibaena subaurea spec. nov. 



Forewing : pale yellow, striated with olive and green ; costa green ; apex 

 broadly green, narrowing to anal angle ; cell-spot dark green. 



Hindwing : with a narrow green marginal border, its inner edge diffuse ; 

 rest of wiug pale yellow, with olive striae.
