JCOVITATES ZOOLOGICAE XXII. 1915, 383 



fifths, straight; postmeiliau at aliout f! mm. from tenueii, forming a very slight 

 inward curve ; vague inJications of a subtermiual (esi)ecially as a strong inward 



curve between R- and tornus) and of olive distal border. Him/wing shaped 



nearly as in //. banakaria Plotz (Steit. E/it. Zeit. xli. 3(J2 ; = toHuosa Warr., Nov. 

 Zool. iv. 258), rather more produced tornally ; coucolorous with forewing, but 

 even more vaguely marked (except the antemedian, which reaches inner margin 

 beyond middle), costal margin pale. 



Both wings beneath reddish orange, the forewing somewhat shaded in and 

 behind the cell, and in a streak from cell to apex with blue-grey. 



Bitye, Ja River, Cameroons, 2000 ft., lesser rains, April— May 1007 (G. L. 

 Bates). Type in coll. Rothschild. 



Probably related to the banakaria group, but much larger and aberrant in the 

 stalking of SC^ of forewing. 



Dysnymphus gen. nov. 



Face with appressed scales. Palpus very short. Tongue short. Antenna in 

 both sexes bij)ectinate, with long branches, last few segments nearly simple (as in 

 Osicerda). Pectus slightly hairy. Femora glabrous. Hindtibia with all spnrs. Abdo- 

 men rather robust ; in S more or less tufted beneath. Forewing with costa arched ; 

 termen with a deep, rounded excision between SC^ and R^, very strongly oblique 

 posteriorly ; cell long (about three-fifths), D(;' extremely long, oblique ; SC 

 arising from C, SC^ from stalk of hiC'~\ anastomising slightly with SC, SC^~'' 

 very long-stalked, R- from middle of DC, M' well separate. Hindwing with 

 termen oblique to SC'-*, straight from SO^ to R', somewhat bent behind R' ; in 6 

 folded at inner margin, forming a kind of hair-fringed pocket beneath ; cell over 

 one-half, DC very long, D(J-~^ iubent, becoming strongly oblique ; C approximated 

 to SC rather shortly near base, R" wanting, M' widely separate from R\ 



Type of the genus : Di/SHymphus monostigma sp. nov. 



No doubt a very specialised development of Osicerda "Walk. (= Prionia Gueu., 

 nee Hb.). Here evidently belongs JJrepana (?) bioculata lloil. (^Ent. News, 

 iv. 177). 



139. Dysnymphus monostigma sp. nov. 



<?, 27 mm. Head and thorax olivaceous ; abdomen whitish with an olivaceous 

 tinge, dorsally mixed with pink. 



Forewing unicolorous dirty olivaceous, with a black sjiot on fijld opposite the 

 origin of M- ; fringe rather paler. Hindwiiu/ white. 



Forewing beneath dirty whitish, becoming olivaceous costally and distally. 

 Hindwing beneath whitish. 



Bitye, Ja River, Cameroons, 2000 ft., September — November lull. Type in 

 coll. Rothschild. 



140. Eurythecodes prolixa sp. nov. 



? , 34 mm. Palpus about as long as diameter of eye. Tongue slight. 

 Antennal pectinations rather long. Head, body, and legs concolorous with wings, 



Forewing very broad, termen shaped about as in Epigijnoptenjx jiuredinaria 

 Gu(5u. ; pale grey, the median area weakly irrorated with olivaceous brown, the 

 basal and distal areas olivaceous, shaded with pinkish brown ; lines dark olivaceous
