D. pasteon Ham. Druce (66 b). rj. Wings above dark blue; forewing at the costal margin and apex pasteon. 
blackish; hindwing at the costal and proximal margins blackish and with black veins. Wings beneath of a 
brown ground-colour; forewing at the posterior margin white and with a whitish band at the margin; the trans¬ 
verse vein is bordered with whitish; hindwing across the apex of the discal cell with a whitish nebulous band 
extending from vein 8 to the proximal margin, and scaled whitish at the margin: a black submarginal dot in 
area 6 and a larger one encircled with red in 2. Cameroon: Bitje. 
D. kedassa Ham. Druce (66 b) deviates from the following species only by the marks mentioned kedassa. 
in the review. Expanse of wings: about 27 mm. The $ on the wings above is entirely without the blue colour 
of the Cameroon: Bitje. 
D. catalla Karsch (&§=k). <$. Wings above beautifully dark blue with veins of the same colour, fore- catalla. 
wing at the costal margin and apex narrowly black, hindwing as far as the margin blue with black fringes, 
only in 1 a, 1 b, 7 and 8 black, the apex of area 7, however, blue; the mealy spot is large, light yellowish, broadly 
encircled by black. Wings beneath dark blackish-brown; in the marginal half of the forewing with 3 fine, 
white transverse lines, the innermost of which is almost straight, the distal ones being angularly broken; in the 
marginal half of the hindwing with 4 fine, white lines, of which the most distal is close to the margin; the 
basal parts of both wings either in the cell or at the cell-end scaled and striated white; or as far as the first 
transverse line quite unicolorous without markings. Togo to Cameroon. 
D. Violetta Auriv. (68 a). <$. Both wings above as far as the margin very dark violettish-blue without violetta. 
markings; the under surface only deviates from the allied species by the marks stated in the review. $ unknown 
to me. Gabun to Congo. 
D. deritas Hew. (66 b) only differs by the marks mentioned in the review. The principal form has deritas. 
an expanse of about 29 mm. Cameroon to Angola. — aucta Karsch has an expanse of 38 mm, but otherwise it aucta. 
exactly corresponds with deritas and is presumably only a form of it. Togo to Cameroon. 
D. corruscans Auriv. (66 b) chiefly deviates from deritas by the strongly reflecting upper surface corruscans. 
of the $ forewing being blackish towards the margin and by the $ upper surface being very dark, bluish-violet. 
Anal lobe of the hinclwing in the above black, beneath towards the base bordered by red, in the $ above 
red, encircled by black, beneath as in the <$. Cameroon to Ogowe. 
Second Subdivision. 
Both wings beneath with a distinct transverse streak or transverse spot at the end of the discal cell, 
hindwing at vein 3 angled, but not tailed. 
Review of the Species. 
A. Fore wing beneath between the discal cell and the submarginal line only with a single, almost straight, 
undulate or level transverse line. 
a. Under surface light grey or whitish-grey with a fine, yellow, feebly undulate, discal transverse line. — 
$ (as far as it is known): forewing beneath at the base of area 1 b with a black mealy spot, above 
mostly blue. 
*. The discal transverse line beneath is distally not bordered with white. — <$. Hindwing above in 
1 c with a black hair-pencil. D. Icafuensis. 
**. The discal transverse line beneath is distally bordered with white. — Hindwing without a pencil 
in the area 1 c. D. catori. 
D. bemba. 
(3. Under surface dark grey, with a faint greenish hue. The discal transverse line of the forewing beneath 
is blackish, distally bordered with white; that of the hindwing irregular, composed of blackish-grey transverse 
streaks or spots distally and often also proximally bordered with white. D. zela. 
B. Forewing beneath between the discal cell and the submarginal lines with two whitish transverse lines, the 
proximal one being towards the margin, the distal one towards the base bordered with brown or blackish; 
these two transverse lines consequently enclose a more or less distinct transverse band. 
a. The discal band of the forewing beneath is distinctly interrupted at vein 4. — <$. Wings above for the 
greatest part light blue; forewing above with a large, black velvety spot at the apex of the discal cell, 
beneath with a large mealy spot at the base of area lb. D. caerulea.
