 is absent in septentrionaUs. 



7. Amiocera cyanoxantha Mab. (1893) 



Zygaena cyanoxantha Mabille, Ann. Soc. Eni. Belij. p. 57 (1893) (Abyssinia) ; id. & Vuill., Nov. 

 Lepid. xii. p. 151. tab. 21. fig. 6 (1895). 



The specimen described and figured by Mabille is said to be a cj from 

 Abyssinia. Mabille describes the tibiae as being red on the outer surface, which 

 points to a ? rather than a c?, judging from the specimens of Amiocera which I 

 described in 1907 a,s poecila, in which only the midtibia has nearly the whole outer 

 surface red. The abdomen has no red scaling. The forewing is blue according to the 

 description, but has a decidedly green tint in the fignre. We have a small number 

 of specimens with blue forewing from Fort Crampel, French Congo, towards the 

 Bahr-el-Ghazal. These may be true cyanoxantha. They are, moreover, distinguished 

 from poecila by the black borders of the orange spots of the forewing being broad. 

 The abdomen of one of the five S i and of the only ? has the tergites 3 to 7 red 

 with diffusely black centre ; in a second specimen very few red scales are present, 

 while the three other S S are intermediate. 



In the specimens from Uganda which I described as poecila Jord. (1907), the 

 abdominal tergites 3 to 7 are bright red in both sexes, without black central spots. 

 We now, however, have two cJc? from Eutebbe, Uganda, ia which the abdomen has 

 only a few red scales, and the British Museum has others without any red scaling 

 on the abdomen. The dark-bodied and red-bodied specimens do not appear to 

 differ in any other way. The body and forewing have a decidedly green tint in all 

 these specimens, and the black borders of the orange spots are narrower than in 

 the above-mentioned examples of cyanoxantha. This bluish green form is for the 

 present best treated as a geographical dimorphic race : A. ci/anoxantha poecila 

 Jord. (1907), from Uganda and Toro. 



Our only two examples from the Wemi R., Toro, obtained by Dr. J. W. Ansorge 

 on April 21, 1899, have a peculiar pattern : ab. angulifera ab. nov. The posterior 

 spot of the constricted median band joined to the posterior submarglnal spot. In 

 one of the two specimens the short lower arm of this angle-shaped marking is 

 connected with the subapical spot on the right wing, whereas on the left wing 

 only the black borders of the spots merge together. The abdomen red as in true 

 poecila. 



A. eleyans Weym. (1903'), from British and German East Africa, in which 

 neither sex has red scaling on the abdomen, while the spots of the forewing are red, 

 is perhaps a geographical race of cyanoxantha. 



8. Amiocera amoena Jord. (1907) 



In Entom. Rundschau, 1909, p. 108, Herr E. Strand describes two specimens 

 oi Amiocera from German East Africa as A. imperialis Butl. var. taborensis Strand 

 and ab. lonyimaculata Strand. The two names are given to the same specimen. I 

 doubt whether the examples belong to imperialis Butl. (1898). What Strand calls 

 ■ imperialis is probably amoena Jord. (1907). The two species are easily distinguished 

 by the colouring of the head and thorax, amoena having a red head and red pro- 

 notnm, imperialis a green head and pronotum and red shoulder-stripes.
