186 NOVITATES ZOOLOGICAE XXIII. 1916. 



Underside more greyish, the forewing somewhat less, the hindwing somewhat 

 more strongly marked than above. 



Caracas, Venezuela, 2 ? ? in coll. L. B. Prout. 



Subfamily GEOMETRINAE 

 74. Apicia mediosignata sp. nov. 



c?, 43 mm. Face brown above, whitish below. Palpas mostly dark fuscous, 

 parts of the first and third joints pale. Head and body concolorous with wings. 

 Antenna pectinate to rather near apex. Hindtibia moderately strongly dilated ; 

 mostly dark-coloured. 



Forewing with costa shouldered at base, gently arched to beyond middle, termen 

 very gently concave anteriorly, strongly angled at R 3 , the posterior part being- 

 straight and very oblique ; cell considerably over one-half, DC strongly curved 

 behind, M 1 therefore rather widely separate from R 3 , stalk of SC 1-2 connected by 

 very short bar with C, SC 2 also connected with SC 3-4 ; flesh-colour, with sparse 

 black irroration ; proximal area olivaceous in cell, somewhat vinaceous posteriorly ; 

 antemedian line rather far from base, slight, only thickened for a short distance 

 about SC and at hindmargin, rather strongly bent in front of M; median shade 

 indicated by a thick mark running from costa almost to cell-dot ; cell-dot moderate, 

 black ; postmedian line from a thick black costal mark at five-sevenths, then fine 

 and exceedingly oblique outward along SC 5 almost straight to R 1 , oblique inward 

 and very slightly incurved to hindmargin little beyond the middle, throughout this 

 part of its course scarcely marked except by black vein-spots and by a slight pale 

 line which accompanies it distally and is very shallowly lunulate inward between 

 the veins ; an olivaceous shade proximally to the postmedian, a vinaceous shade 

 distally ; some olivaceous shading in subterminal region and some extremely vague 

 dark spots near apex ; terminal line almost obsolete ; fringe flesh-colour, irregularly 



mixed with olivaceous. Hindwing with apex nearly squared, termen waved to 



R 3 , here bent and with a moderate tooth, then almost straight, tornus pronounced ; 

 cell about one-half, DC 3 and M 1 nearly as on forewing ; concolorous with forewing ; 

 discal dot large, black, confluent distally with a conspicuous, somewhat sinuous 

 black median (postmedian) line which runs from SC 3 to abdominal margin but is 

 interrupted between M 1 and M 2 and between M 2 and the fold ; olivaceous and 

 vinaceous shades proximally and distally hereto as on forewing; the pale sub- 

 terminal line and its olivaceous proximal shading rather more definite than on 

 forewing, but not sharp. 



Forewing beneath more suffused with dark smoke-colour than above, especially 

 anteriorly and proximally, hindmargin and a spot at apex pale ; discal dot black, 

 postmedian line indicated, fairly conspicuous at costa. Hindwing beneath more 

 blurred, but with the markings of the upperside indicated. 



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

 L. B. Prout. A second example dated March — April. 



Perhaps near jaspidaria Guen., but the hindwing not dentate. By shape this 

 species would probably be referred to Loxapicia Warr., which, however, cannot be 

 regarded as a tenable genus, various intergrades and sexual differences bridging 

 over the distinctions.
