mens before us are rubljed at Ihc base of wing and we cannot tell 

 whether a t. a. line is present or not; there shoukl. however, be no 

 difliculty in recognizing the species owing to the peculiar frontal struc- 

 ture. 



Antaplaca atkolinf.a sp. nov. (Plate I, fig. 23.) 



Palpi, thorax and primaries orange ; t. a. line black, partly double, nearly 

 npright, twice waved, the inner line of the two extending only between sub- 

 costal and anal veins, at times broken; orbicular and reniform outlined in 

 black; the former large, open towards costa, touching t. a. line in its upper 

 portion, the latter narrow, well excised outwardly, connected with costa by a 

 black line : below the two spots a waved black hne runs through the centre of 

 the median space, incurved in submedian fold; t. p. line double, black, both 

 lines tending to become broken, starting from costa near apex it is incurved 

 slightly opposite cell and strongly below vein Cui ; fringes checkered with black. 

 Secondaries deep smoky with yellowish fringes. Beneath primaries dark fuscous 

 with costa and outer margin narrowly orange, and fringes orange and black ; 

 secondaries smoky with yellow fringes. Expanse, 25 mm.

 Types, Coll. Barnes. 



Related to dcla Druce which ue have before us ; differs in that 

 orbicular and reniform are not filled in with paler color than the ground 

 color of the wing, the black suflfusion around them is entirely lacking, 

 and the black lines are broken, not so sharply angled and without the 

 sHght suffusion seen in dcla. The frontal protuberance in both this 

 species and dcla differs from that of dimidiata. the type of the genus 

 Aiitaplaga. For this latter species Hampson correctly characterizes it 

 as a "truncate corneous prominence with raised edge and central pro- 

 cess and corneous plate below." In atrolinca and dcla, instead of the 

 circular cup-like process, (Hampson's prominence with raised edges) 

 we have a transverse lunate prominence, the front edge of which is 

 drawn out centrally to form a vertical ridge; below this is the in- 

 f raclypeal plate. This may represent a new genus ; we prefer, how- 

 ever, for the present to refer these two species to Aiitaplaija. 



Chalcopasta fulgens n. sp. 



Head and thorax purple, thickly sprinkled with white scales. Primaries 

 golden-yellow, rather metallic ; costa narrowly margined with purple, expand- 

 ing beyond the middle into a large irregularly quadrate purple patch extend- 

 ing downward to vein Mj and outward to just before apex of wing; this patch,
