MICROLEPIDOPTERA OE SDW GUINEA 
58 
without cubital pecten, 2 from beyond 3 / 4 , 3 and 4 short-stalked from 
angle, 5 closely approximated, 6 and 7 stalked. 
Typus generis Aplastoceros pmeploca spec, nov., male, female. 
Closely allied to Mimeoclysia Diakonoff, 1941, from Java, and to 
Rhomboceros Meyrick, 1910, which both represent developments of the 
same type. Aplastoceros can be distinguished from the first named genus 
by the separate veins 3 and 4 in the fore wing, and from the last named 
by the normal antennae in the male and by the slender palpi. Super- 
ficially it resembles Epagoge Hubner. The genitalia in all the three genera 
are of the same type.

cj> 15—16.5 mm. Head light ochreous, densely mixed with fulvous- 
brown, especially on face. Palpus dark brown, apex of median and terminal 
segments ochreous. Antenna ochreous, ringed with dark brown. Thorax 
brownish-fulvous, mixed with ochreous, tegula ochreous posteriorly. 
Abdomen ochreous-grey, anal tuft brighter ochreous. Legs ochrcous- 
fuscous, anterior dark fuscous. Fore wing elongate-ovate, costa gradually 
curved anteriorly, straight posteriorly, apex subobtuse, termen slightly 
convex above, rather oblique. Pale whitish-ochreous or pale ochreous 
(one specimen tinged fulvous throughout), suffused with rather bright 
tawny-ochreous, markings brown, blackish and dark grey. Tawny-ochreous 
suffusion along anterior half of wing, with posterior half with scattered 
ochreous patches in indistinct transverse rows; anterior half of costa 
dotted with dark brown; central fascia formed by a small oblique-sub- 
quadrate patch on costa at 2 / 5 , continued to 3 / 4 of dorsum by a faint 
cloudy brownish -greyish suffused fascia, which is dilated in middle; a 
moderate curved-triangular patch on dorsum before V 4 , more or less 
suffused above, posterior edge mostly well-defined, concave, top connected 
by a suffused cloudy brownish-greyish fascia with upper fourth of central 
fascia, marked in disc with more or less numerous dark brown scales,
