NOVITATBS ZOOLOGICAE XXIII. 1916. 175 



In Trans. Ent. Soc. Lond. 1910, p. 229, I provisionally separated Atyria from 

 Cyllopoda by the single areole of the former ; the occasional presence of a very 

 minute distal areole in Atyria (ops and mnemosyne), with SC 2 arising from the 

 stalk of SC 3-5 (in Cyllopoda from cell), does not really vitiate this. The non- 

 pectinate antenna of mnemosyne, however, constitutes it a separate section of 

 Atyria, if not a new genus. 



Subfamily LARENTIINAE 

 55. Hammaptera caeruleosecta sp. nov. 



S, 36 mm. Antennal ciliation almost as long as diameter of shaft. 



Forewing with termen rather strongly oblique ; costal margin whitish and 

 ochreous (probably discoloured from olivaceous), with about nineteen irregular 

 black spots or streaks, mostly indicating the beginnings of lines ; basal and sub- 

 basal area predominantly red-brown with some grey and olive shading and with 

 rather interrupted blackish lines ; that which distally bounds the snbbasal area 

 falls perpendicularly from costa to behind M, is then angled, becomes sinuous and 

 falls nearly perpendicularly on hindmargin, where there is a black spot ; inter- 

 mediate area narrow, vaguely lighter (especially at costa), mixed with greenish ; 

 median area formed of two very variegated (red-brown, olive and black) bars, 

 which become broadly confluent about M 2 , thus enclosing two light-blue patches, 

 the anterior large, containing an elongate fuscous cell-mark, the posterior somewhat 

 8-shaped ; distal edge of the outer of these bars very black anteriorly, the usual 

 indentation at SC 3 deep and acute, the pure white line which follows only distinct 

 anteriorly; distal area bluish white, mixed with olive along the veins and distally, 

 and with a very fine indistinct olive line parallel to and near the postmedian ; the 

 interrupted, lunulate whitish subterminal is accompanied proximally by a dull 

 reddish patch from costa to R 3 , on which stand two almost confluent black marks 

 between the radials, and by some much smaller and weaker reddish shading 

 towards tornus ; termen with pairs of large black dots ; fringe olive, paler distally, 



a fine pale dividing-line ; blackish marks opposite the veins. Hindwing white, 



posterior half of termen with pairs of black spots ; these become minute at R 2 , 

 scarcely traceable at K 1 . 



Underside similar to that of sharply-marked trijectata Walk., which has rather 

 less long forewing than the present species. 



Uruhuasi, S. Peru, 7000 ft., April— May 1910 (H. and C. Watkins). Type in 

 coll. L. B. Prout. 



Ab. incarnata ab. nov. Forewing between basal and median areas light rose- 

 colour, unmarked; median band in its posterior half (or more) strongly suffused 

 with the same, the blue therefore restricted to a small space about the 'cell-spot; 

 subapical patch of the same light rose-colour, thus slightly lighter than in the 

 name-type. 



56. Hammaptera polychroma sp. nov. 



<$ , 33-34 mm. Structure, shape, etc., as in the preceding. 



Forewing from base to postmedian line predominantly olive-green with slight 

 mixture of grey, but a little varied at base and parts of costa and hindmargin with 

 more ochreous scales ; subbasal patch vaguely indicated by some darker lines, 

 angulated in cell ; between this and median area a narrow reddish band, also
