A NEW GENUS AND SPECIES OF ORNEODID^. 253 



Mr. Dudgeon calls the species the " Cocoa-bark Sapper," 

 and it is thus referred to in his * Fourth Report on Agricultural 

 and Forest Products of the Gold Coast to Secretary of State 

 Colonies, 1909.' 



A NEW GENUS AND SPECIES OF ORNEODID^ (Lep.). 

 By T. Bainbrigge Fletcher, E.N., F.E.S. 



MiCROscHiSMUs, nov. gen. 



(/.'.ixjC/J?. short ; a-xj.au.o<;^ a cleft.) 



Maxillary palpi absent. Labial palpi very long, at least twice 

 length of head, densely scaled. Fore wing cleft into six segments 

 from beyond two-fifths ; hind wing cleft into six segments within 

 half. 



Type.— M./or<is, Wlsm. (T.E.S. 1881, 284-5, t. xiii. f.49). 



The above forms the fourth described genus of the Orneo- 

 didcTB, which may now be tabulated generically as follows : — 



-J ( Hind wing cleft into seven segments Triscadecia. 



I Hind wing cleft into six segments 2. 



n f Fore wing cleft from at least one-third Orneodes. 



I Fore wing cleft from about half only 3. 



q (Labial palpi at least twice length of head Microschismus. 



\ Labial palpi not exceeding length of head Pcelia. 



Besides the above-qaoted type the genus Microschismus 

 contains the following new species : — 



Microschismus anteiinatus, n. sp. 

 ^ . Exp. 16 mm. Labial palpi very long (about thrice length of 

 head), down-curved, densely scaled so that proportions of joints are 

 not visible but third joint is apparently very short, fuscous. Maxil- 

 lary palpi absent. Haustellum feebly developed. Head roughly 

 scaled, fuscous. Antennae fuscous, each joint emitting a pair of 

 bristles slightly longer than length of joint on which they arise. 

 Thorax fuscous. Abdomen fuscous, suffused with blackish ; anal tuft 

 pale fuscous. Legs fuscous grey ; posterior tibiae with two pairs of 

 moderate, unequal spurs. Fore wing cleft into six segments ; first 

 cleft from about two-thirds, second from slightly beyond half, third 

 from about two-thirds, fifth from about half, fourth from halfway 

 between third and fifth ; segments linear : light greyish-brown with a 

 very slight yellow tinge minutely irrorated with dark-fuscous dots, 

 especially evident on basal third : bases of third, fourth, and fifth 

 clefts outlined in dark-fuscous, forming a conspicuous line running 

 obliquely inwards across the wing ; first segment crossed by two in- 

 distinct dark-fuscous bands at about one-third and two-thirds of its 

 length ; remaining segments cut by a moderate dark-fuscous band at 

 about three-fifths of their lengths, preceded and followed by slightly 

 paler spaces ; apices of all segments with a blackish dot. Cilia
