MICROLEPIDOPTERA OF NEW GUINEA 
Two specimens, rather differing in ground colour but conspecific according 
to the genitalia. Allied to preceding. 
Mesocalyptis gen. nov. (fig. 295) 
Head rough. Ocellus posterior. Proboscis developed. Antenna moderately 
ciliated in male, ciliations under 1. Palpus moderately long, ascending, 
rather slender, with roughly apprcssed scales median segment little 
dilated, broadest somewhat beyond middle, terminal segment moderate, 
pointed. Thorax without crest. Fore wing without costal fold, without 
raised scale-tufts, lb furcate, 2 from beyond middle, 3 from before angle, 
4 from angle, 5 parallel, 7 and 8 stalked, 7 to termen, 10 from 3 / 4 , 11 from 
middle. Hind wing without cubital pecten, 2 from 1 / 3 — 1 l 2 , 3 from slightly 
before angle, close to 4, 4 from angle, 5 approximated, 6 and 7 short- 
stalked. 
Typus generis Mesocalyptis morosa spec, nov., male. 
Fig. 295: Mesocalyptis morosa gen. nov., spec, nov., male, wing neuration and head. 
Closely allied to Tremophora gen. nov. but without any trace of abdomi- 
nal organs. Superficially approaches Arizdana gen. nov., but without 
costal fold and with slender palpi ; also approaches Procalyptis Meyrick 
(both genera in the tribe Cacoeciini) but with longer palpi, without costal 
fold in fore wing, and with 6 and 7 stalked in hind wing. Forms together 
with the preceding genus and with Taeniarchis Meyrick a natural group, 
with the genitalia of a very similar type. 
Key to the species of Mesocalyptis 
1. Head dark ferruginous-brown: fore wing with ground colour rather dark brown, 
markings not conspicuous morosa spec. nov. 
Head pale tawny-fuscous; fore wing with ground colour pale ochreous-fulvous, 
markings conspicuously darker zonata spec. nov.
