70 New Lepidoptera collected by Mr. T. A. Barns 



It will be seen that the eupale subsp. and dilutus overlap in distribu- 

 tion but we have no evidence of both occurring in the same place. 



G. eupale subsp. is found together with subornatus in the Cameroons, 

 and if our diagnosis is correct it also occurs with a race of subornatus in 

 Uganda and the Ituri. 



C. dilutus is not known farther west than Angola, but occurs 

 together with a subornatus form at Nairobi. 



The three species may generally be easily distinguished, but the 

 subornatus race may be confounded with dilutus. It will therefore 

 be useful to give here the results of certain measurements which 

 indicate not only the three species but also the races and to which 

 species they belong. 



On the underside of the hind wing there is a row of antemarginal 

 spots and a row of what may be termed submarginal spots. The 

 arrangement of these series of spots is not the same in each species, 

 and a comparison of typical subornatus with eupale subsp. will show 

 that the antemarginal spots are nearer the margin in subornatus than 

 they are in eupale, and that the spots of the submarginal series occupy 

 different positions in the two species, especially the spot in cellule 3. 

 The submarginal spot in cellule 6 is more or less removed from the 

 band, owing to the straighter or more oblique position of the band. 

 Measurements were made (1) of the distance between the antemarginal 

 dot in cellule 3, measured from the centre of the black dot, and the 

 outer edge of the submarginal dot in 3 ; (2) of the distance between 

 the submarginal dot in cellule 6 and the inner edge of the band. 



These measurements were made on specimens which showed the 

 markings plainly. It sometimes happens that specimens occur with 

 the spots absent. The following specimens were taken : — 

 G. eupale eupale ... ... ... 10 



G. eupale subsp. ... ... ... 52 



C. dilutus ... ... ... ... 25 



G. subornatus ... ... ... 4 



C. subornatus subsp.... ... ... 9 



The results are tabulated on next page. 

 1. The measurement in cellule 3 : — 



eupale, fifty-two specimens have a distance of from 2 to 



2'5 mm. 

 subornatus, nine individuals have a distance of from 2'0 to 



2*5 mm. 

 dilutus, nineteen individuals have a distance of from 3'0 to 

 3"5 mm.
