54. Tagiades BRiGiDA, var. 



Antigonus brigida, Plotz, Stett. ent. Zeit. 1879, p. 361. n. 32. 



But for the fact that the type of this species was from the 

 Cameroons, coupled with the remark " Diese Art sieht Trichoneura, 

 Feld., ahulich," I should certainly have failed to identify it ; the 

 description, " Hiud wings above with broad straw- or orange-yellow 

 borders," hardly represents an insect in which more than half tlie 

 hind wing is bright orange ; nor does the statement that there are 

 "six hyaline white points " in the front wings answer to a specimen 

 with ten. However, I am unwilling to risk describing as new a 

 species which may he subject to variation and tlierefore already 

 described as above, or which may have been incorrectly described. 



55. CeRATRICHIA ARGYROSTICTA? 



Apaustus argyrosticta, Plotz, Stett. ent. Zeit. 1879, p. 358. 

 n. 22. 



One example so nearly approaching the description of the above 

 that I think it can hardly be distinct. 



HETEROCERA. 



56. PsEUDOPONTIA PARADOXA. 



Gfobiceps paradoxa, Felder, Pet. Nouv. Ent. n. 8 (1869). 



Gonophlebia paradoxa, Felder, /. c. n. 24, p. 95, fig. (1870). 



Pseudopontia calabarica, Plotz, Stett. ent. Zeit. 1870, p. 348, 

 pi. 2. figs. 1 a-f. 



I canuot understand why this insect has been referred to the 

 Butterflies ; the structure of the antennas and the neuration are 

 altogether peculiar. In my opinion the genus is more nearly related 

 to the Chalcosiid moths.
