Josiodes celena.

J. celena Wkr. (= trajecta Wkr.) (35 f) greatly resembles batesi, but it has
no subapical spot. Hindwings above and beneath quite black. In the male the
orange-yellow abdominal stripes only extend to the 5th segment, in the female
to the terminal segment. -- purpurata Btlr. exhibits on the hindwing beneath
a small orange spot. Expanse of wings: male 30 to 34 mm, female 40 mm.
Distributed from Surinam, Brazil as far as Bolivia and Peru.

The paragraphs on batesi and, through it, caerulescens referred to (same
page):

J. batesi Fldr. (= entella Drc., quadrifascia Rothsch.) (35 f). From the
preceding it differs by a broader orange stripe-band extending to the costal
margin, and a small subapical spot. Hindwing beneath with an orange spot;
abdomen laterally striped orange. Expanse of wings: 40 mm. British Guiana;
Brazil.

J. caerulescens Hmps. (35 e) is distinguished by an intense blue lustre; the
oblique spot of the forewing is light yellow and removed more towards the
margin. Expanse of wings: male 38 mm, female 46 mm. Colombia.
