of three times the width of that in C. Viola ; the sub-marginal spots are smaller, and 

 the red and green marginal border duller ; abdominal area broadly pale greenish- 

 grey : under surface altogether different, glaucous-grey, the black markings much 

 more prominent, broader ; a distinct white belt beyond the middle of the wings ; 

 the lunated red discal markings of the primaries replaced by a series of spots 

 between the upper radial and sub-median veins, the first three indistinct, dusky, the 

 last three black ; the discal lunated series of the secondaries darker and duller, and 

 the ill-defined band limiting the basal area on these wings narrower, less irregular, 

 and better defined. Expanse of wings, 75 mm. 



Mamboia, E. Africa (Sir J. Kirk). 



By referring to my figure of C. Viola (Proc. Zool. Soc, 1865, pi. 

 xxxvi, fig. 4), it will be easy to identify this insect ; its proper location 

 is evidently between this species and C. Jocaste, of Senegal. 



Teeacolus incbetus, sp. n. 



? . Very near to the female of T. Auxo, but considerably larger ; all the dark 

 brown markings better defined and broader, the external border of the primaries 

 being decidedly broader, and the macular orange area between it and the connected 

 series of discal black spots of little more than half the width, and much more 

 arched ; the discocellular spot of about four times the size ; the discal markings of 

 the secondaries so well marked as to indicate an irregular zigzag line, the first, 

 second, and fourth divisions of which are dark brown, the last-mentioned being a 

 cuneiform brown spot; the marginal spots very large: wings below altogether 

 brighter and clearer in colour, the markings better defined ; the discocellular spot of 

 primaries pupillated with silver, that of secondaries consisting of a partially black- 

 edged silver spot with ochraceous iris. Expanse of wings, 55 mm. 



Mamboia, E. Africa (Sir J. Kirk). 



The female of T. Auxo expands 43 millimetres, that of the closely- 

 allied (if distinct) T. Topha, 42, that of T. Keiskamma, 43 ; so that T. 

 incretus may he safely said to exceed all its nearest allies by 12 milli- 

 metres in expanse of wing.

GOLD COAST. 



BY W. F. KIEBY. 



ANTHEEiEA MACEOPHTHALMUS. 

 Expanse, 5 inches. Warm fawn colour, shading almost into salmon-colour on 

 the hind-wings ; fore-wings with the basal line consisting of a rather indistinct 

 pinkish-white line, bordered with black within, straight across the cell, forming a 

 rectangle below, and ceasing half-way between the sub-median nervure and the 

 inner margin ; eye of moderate size, not quite round, paler than the ground colour,
