(408) Ifi. Terias brenda maculata Aurivillius 



Terias brenda var. iiiacidata Aurivillius, 1910, Seitz, Gross-Schmett., XIII, p. 64, 

 PI. XXIIC. 



Two males taken at Ganiangui in February, and an aberrant female 

 caught at Bafwasende in January. This is the winter form of the species.

The specimens which I refer to this species fall into two groups, one 

 in which the marginal band of the primaries at the outer angle is broad 

 and strongly produced on vein 2 as an inwardly projecting tooth, the 

 other in which it is narrow and only slightly angulated on vein 2. Of 

 the first group there are in the present collection twenty-two males, the 

 majoiity taken at Faradjc in November. (3ne is labelled as from Munie 

 Katoto, one from Kwamouth, one from Gamangui, and one from Basoko. 

 The four last mentioned were taken in the months of June and July. 



Of the second group there are twenty-six males and six females. Of 

 these, thirteen males and two females were taken at Medje, one male and 

 one female in January, one male in September, all the rest in June and 

 July. Two males and a female are labelled as from Gamangui, taken in 

 February, the remainder at Niangara and Faradje in November, so 

 far as the labels indicate the date of capture. 



(410) 2a. Terias senegalensis bisinuata (Butler) 



Terias hisinuaia Butler, 1876, Ann. Mag. Nat. Hist., (4) XVIII, p. 485. Aurivil- 

 lius, 1910, Seitz, Gross-Schmett., XIII, p. 64, PI. xxii^/. 



This, which is claimed to be the winter form of T. senegalensis and 

 is characterized by heavy markings on the under side of the wings, is re- 

 presented in the collection by fifteen males, twelve taken at Faradje in 

 November, so far as the labels are dated, though many of the labels 

 lack any indication of the month. One was captured at Niangara in the 

 month named, one at Kwamouth on July 15, 1909, and one at Medje 

 in August. Most of the specimens have the marginal band of the 

 l)rimaries broad at the outer angle and strongly toothed inwardl}', but 

 there are several in which it is narrow and only slightly angulated on 

 vein 2, in this respect resembling the specimens in the second group re- 

 ferred to under the preceding form.
