species of Aef/ocerd, Latr.. Aeijoceropsis Karscli, and Mitojjlirys Karscli, but tbose 

 which Kar;>ch give;^ are partly not prominent enough (form of antennae), partly 

 incorrect (absence of vein 5 from hindwing:*, narrowness of forehead in front of 

 antennae in J, position of vein 2 to hindwings).

 Xov. Lejj. 12. p. 157. I. 22. f. 2 (1895), is nothing else but A. triraeni Feld. with the 

 discal area of the hindwings pure white; in typical irimeni the hindwings are 

 slightly tinged with orange ; in tricolor Druee they are orange. These three forms 

 occur together in Xatal, and are certainly not specifically dififerent, as intergrada- 

 tions pro\e. 



Mitoplirys fubricala Karsch, Erd. Xachr. 1895. p. 355. t. 2. f. 4, from " Jsieder- 

 Guinea," is based on a specimen of Aegocero tigrina Druce with the marginal region 

 of the forewings black instead of reddish brown. In the figure of tigrina the thorax 

 and base of abdomen are unicolorous ; this is the case only in strongly nibbed 

 specimens. Tig'rino has the same dark thorax striped with white, and the same 

 black dorsal line to the abdomen, which we find mentioned in the careful description 

 of fabriaitct ; but the abdomen of fahricata is said to be yellow with a black dorsal 

 line ; oiu- good specimens of tigrina have the posterior segments black, edged with 

 white. Judging from the photograph of the only specimen of fabricata which Karsch 

 ix)ssessed when he described the species, this specimen is rather wora, and there- 

 fore the difference in the colom' of the abdomen of fttbrimta and tigrina could 

 very weD be due to the bad condition of the type of fabricata. The markings of the 

 forewings are in om- series of thirteen specimens so variable that the differences 

 shown in this respect by the figures of tigrina Druce and fahricata Karsch are of no 

 importance whatever. One of our thirteen specimens has the marginal region of the 

 forewings coloured Mke fahricata Karsch; all the others, mostly from the same place 

 (Gaboon), have it like tigrina Druce. The small white spot between the lower 

 median nervules to the forewings stands often isolated, as in the type of tigrina Druce; 

 sometimes it is merged together with the subapical baud, as in fahricoAa Karsch : and 

 in one of om' specimens it is absent. The linear white mark at the apex of the cell 

 is in some cases three times as broad as in others. The submediau yellowish band is 

 often dilated at the submediau nerviire, as in Karsch's figure : sometimes it is of even 

 breadth and does not reach that vein ; in other examples it is club-shaped, as in 

 Druce's figure. On account of the marginal region to the forewings being black, 

 fahricata Karsch might be kept separate as an indi\idual aberration of tigrina 

 Druce, unless it could be proved by the presence of characters not mentioned in the 

 description and not to be seen in the figm-e that it is distinct. K. .1.

ilALE. — All four wings black. Forewings with a minute white dot at the base. 

 A triangular white patch one-fourth from the base extends obliquely fi-om below the 

 costa to the submediau vein, not quite 3 millimetres in breadth at the wridest 

 point. One-third from the apex the forewings are crossed by a second oblique white 

 band, 2 millimetres in breadth, which extends from the costal ner\-ure to the second 

 median vein. Near the white basal dot below the costa is a small patch of blue 

 scales; a linear spot of blue is situated just l)eyoud the middle of the cell, and a 

 longer one on the discocellular veinlets. There is also an indistinct blue line outside 

 the subapical white liand, and anotlier along the lower median vein, a few scattered 

 blue scales being also on the submediau vein. Hindwings with a large di-ciil white
