( 178 ) 



Underside of forewings blackish ; a small ochreons whitish apical blotch ; upper 

 arm of pale baud beyond central fascia swollen into a broad pale blotch ; inner 

 margin and lower half of hindmargia paler ; hindwingdull ochreons, with five or six 

 curved dentate lunulate grey lines ; a curved grey submarginal band preceded by a 

 slightly ])aler band. Face, thorax, and abdomen dark grey ; vertex, collar, and 

 shoulders mixed with pale ochreons scales. 



Expanse of wings : 40 mm. 



One ? between Chimborazo and Chimbo, July 1897 (Rosenberg). 



145. Hammaptera tenera sp. nov. and ab. griselda nov. 



Foirwhiffs : cream-white, shaded in parts with pale pinkish and olive tints ; 

 central fascia formed of two olive black-edged bands, separate above median vein 

 and embracing an obliqne dark linear cell-mark, uniting below median and forming 

 often four flattened aunuli, the outer edge of fascia sometimes marked with dark dashes 

 on veins ; basal space pale, crossed by two pairs of waved lines ; the band preceding 

 and following the central fascia pale, traversed by a central waved olive-ochreous 

 line ; submarginal line whitish, regularly waved, preceded and followed by an olive 

 band, marked with black scales in the spaces beyond the cell and below vein 2, the 

 darker markings in the outer band assuming the form of wedge-shaped streaks 

 towards hindmargin ; marginal spots large, in pairs at the ends of the veins ; fringe 

 pale, cheqnered with darker at the veins. 



Hindwings : cream-coloured ; marginal spots as in forewings, preceded b}' a 

 narrow pale grey border ; fringe wholly pale. 



Underside cream-colour, suffused with pale olive-grey except along inner margin 

 of forewings ; marginal border dull blackish, broad in forewings, narrow in hind- 

 wings ; in the former the apex and a small marginal spot below vein 4, as well as a 

 narrow baud preceding the fascia are pale cream-colour ; cell-spots distinct. Head, 

 thorax, and abdomen cream-coloured tinged with olive and pinkish. 



Expanse of wings : 26 to 30 mm. 



One c?, two ? ? from Parana (type), Entre Rios, Argentina ; also one ? from 

 Claparo, Port of Spain, Trinidad, December 189(j (Dr. lleudall), and one ? from 

 Venezuela (Mocquerys) ; a 6 from Jamaica does not seem to dift'er. 



The pencil of hairs in the abdominal fold of hindwings of 3 is pale like the 

 ground colonr. 



The insect is delicate in colonr and soon bleaches, very few specimens appearing 

 fresh. 



The ? ? can be distinguished from pale ? ? oi E.fringillata Guen., which they 

 somewhat resemble, by the darker border of the forewings beneath reaching to vein 

 2 instead of stopping short at vein 4. 



In a c? from San Pedro Sula, Honduras (bought from Herr Fruhstorfer) tlie 

 ground colour is whitish overlaid with grey, without any pink, and with very slight 

 olive tints visible. At first sight it appears very different from the type form, and 

 may be distinguished as ab. griselda. 



146. Hydriomena praelatata sp. nov. 



Forewings : pale olive-green, with darker green, more or less confluent, striae ; 



the base and transverse fasciae purple-brown ; the latter with deeper wavy edges, 



and all darker and forming blotches on the costa ; the first three bent on the median 



vein ; first near base, interrupted at middle ; second broad, from one-fourth of costa
