'6'22 NOVITATBS ZOOLOOICAE XXII. 1913. 



2fi. EucUoris undulilinea (Wair.) 



Eucrosiea uiulnlilinea Warr., Anr. Zuul. xii. ^84 (I'.lOo). 

 Comostolopsh (?) undulilinea Prout, Gen. Ins. 129, p. 238 (1912). 



This distinct and jiretty little species — of which, in addition to Warren's type, 

 1 have now seen a second example from Abiiri, Gold Coast, is certainly a derivative 

 of Comibaena with the <? frennlnm obsolete — i.i'. taxonomically a Euchlon.i, 

 though some minor differences in structure and its geographical isolation suggest 

 that it is rather a collateral development. The palpus and foreleg unmistakably 

 reveal its relationship. 



27. Acollesis inimetica sp. nov. 



<??, 29-34 mm. Face pale green. Palpus jiale green, uiarked with red on 

 outer side. Vertex and antenna white. Occiput pale green. Thorax and abdomen 

 pale green above, white beneath. 



Forewhig with costa more arched than in the type species ; SC' connected by 

 short bar with f!, well separate from SO^ ; R' not stalked with snbcostals ; colour 

 and markings of Colle.fi.-i mimicu Warr., the postmedian line rather farther from 



termen (3-3-5 mm. at hindmargin), almost entirely obsolete anteriorly to R'. 



Ilitidwiitg also as in C. miniica, the line crossing the middle of the wing (in mimicu 

 rather beyond). 



Underside whitish green, with tlie postmedian line faintly discernible ; costal 

 margin of forewing slightly greener. 



Mount Mlanje, Nyassaland, February 17 (type), March 18, November 19 and 29, 

 1913 (S. A. Neave), all in coll. Brit. Mus. 



Marvellously like Colle.vs mimica (which occurred in the same locality in 

 January and April 1913), except in venation. From A. terminata Prout it differs 

 in its green face, absence of olivaceous terminal line, non-anastomosis of SO' of 

 the forewing with 0, non-stalking of R' and rather less extreme position of R'-'. 



28. Acollesis umbrata densisquamata snbsp nov. 



c?, 32-36 mm. Both wings more densely and evenly scaled with grey- 

 greenish than in name-typical umbrata, recalling the scaling of Nothoterpna ; the 

 white jiostmedian line of both wings rather more slender, not accompanied 

 proximally by a green line or band; a strongly excurved whitish antemedian line 

 faintly traceable on the forewing ; discal dots slightly enlarged. 



Caiala, Bihe, Angola, 2i S, December 19U4 (Dr. Ansorge). 



As I have only seen one example (the type) of name-typieal umbi-at<t, and that 

 is rather worn, it is possible that densisquamata may prove to be a mere aberration. 



Ctenoberta gen. nov. 



Akin to Berta Walk., differing as follows : Antenna in S bipectinate nearly to 

 apex, in ¥ also strongly bipectinate.* Forewing with base of SC obsolete, leaving 

 it to arise out of C and anastomose strongly with SO-, which arises just before SC. 

 Hindwing not excised between radials, the tail at R^ not very long ; M' connate 

 with R^ Discocellulars of both wings oidy slightly indicating the Jierta form. 

 The palpus is not extremely long in either sex, though, as usual, with third joint 

 longer in the ? . The hindlegs are lost in the only known S. 

 * liroken in tlie only known example.
