NOVITATES ZOOLOGICAE XXIII. 1916. 171 



Forewing with SC free, R 1 well stalked, M 1 connate or short-stalked ; pale, 

 translucent blue-green, with some extremely slender violet-grey strigulae ; costal 

 edge bright orange-yellow ; cell-dot small, blackish ; termen very narrowly pinkish 

 white, at vein-ends pure white, a fine, slightly crenulate pinkish line separating 

 the border from the ground-colour ; terminal line blackish, slightly waved, scarcely 



interrupted at vein-ends ; fringe pinkish, with darker spots opposite the veins. ■ 



Hindwing with termen slightly waved, not or scarcely bent at R 3 ; M 1 stalked ; 

 termen and fringe as on forewing, cell-dot still smaller. 



Underside blue-whitish, glossy, the forewing, except at hiudrnargin, with 

 slight pinkish reflections ; costal edge of forewing orauge-yellow ; cell-dots scarcely 

 indicated ; a red terminal line ; fringes nearly as above. 



La Oroya, Rio Inambari, 3100 ft., September 1904, dry season (G. R. 

 Ockenden), type and another $; Tinguri, 3400 ft., August 1904, 1 ? ; La Union, 

 Rio Huacamayo, 2000 ft., November 1904, wet season, 1 ?. All in coll. Tring Mus. 



O. coerulea Warr., which bears some superficial resemblance to this species, is 

 less translucent and differs structurally in both sexes, the c? hindtibia being clothed 

 with very long hair and the ? antenna being simple. 



47. Oospila tricamerata sp. nov. 



S, 29-?2 mm. ; ?, 32-36 mm. Very similar to rufiplaga obsolescens Warr. 

 (J¥ov. Zool. xvi. 86, erroneously as trilunaria ab.), differing as follows : c? antennal 

 pectinations longer ; ? palpus with third joint almost as long as diameter of eye 

 (in rufiplaga half as long). Both wings with the borders duller, the pink parts 

 being white, sometimes almost entirely obscured by dark speckling. 



Forewing with the patch at the radials always developed (in rufiplaga some- 

 times wanting). Hindwing with, a corresponding patch (always wanting in 



rufiplaga) ; tornal blotch of forewing generally narrower, in any case differently 

 shaped, especially in the c?, in which sex in rufiplaga its anterior edge is well 

 rounded, receding to M 2 at termen, whereas in tricamerata it continues to slope 

 forward, reaching termen between M 2 and M'. 



Amazons : Fonte Boa, May (type) and August 1906, July and August 1907 

 (S. M. Klages); Codajas, April 1907 ; a series in coll. Tring Mus. French Guiana : 

 Godebert-Maroni, a S in coll. L. B. Prout. 



48. Oospila circumsignata sp. nov. 



<?, 28-31 mm. Face and npperside of palpus dull red, palpus beneath 

 ochreous whitish. Vertex and base of antennal shaft white ; pectinations about 

 as in albicoma Feld. Thorax above green. Abdomen above mostly wine-purple, 

 anteriorly with some green between this and the pale venter ; anal end and tuft 

 ochreous whitish ; crests dark dull purple, with bronzy admixture. 



Foreiuinq chromium green, more translucent than in albicoma ; costal edge 

 narrowly yellow ochreous ; a very irregular distal border vinaceous rufous, be- 

 coming more vinaceous proximally and separated from the ground-colour by a deep 

 purple line (really vinaceous overlaid with black), which becomes thick and diffuse 

 at the radials and especially between M and hindmargin ; this border narrows to a 

 point at apex, becomes about 4 mm. wide behind R 1 , narrows rapidly behind R 2 , 

 is only 1-2 mm. wide at and just behind M 1 , after which its proximal boundary 

 runs in baseward, and even curves slightly forward, so as to touch M 1 at its origin, 

 finally running almost vertically to hindmargin from origin of M 2 ; a minute black
