a number of families, group III on Verbenaceae, and the remaining 
groups (IV-VII) on Rubiaceae. 
At this stage of our knowledge, an attempt to work out a 
phylogeny within Adelpha would be premature indeed; more 
information on life histories of Adelpha and its relatives (especially 
Old World genera) would be necessary to such an undertaking. 
♦Key to Adelpha Species Groups Based upon 
Final Instar Larvae, Pupae, and Foodplants 
A. larva: body scoli, especially scolus of A2, flattened and 
feather-like; face with dark stripes. PUPA: shimmering silver 
with slender, very slightly twisted horns. FOODPLANTS: 
non-rubiaceous. (A. celerio, sp. nr. celerio, serpa, para'ena ) 
A. larva: body scoli not flattened or feather-like; face patterned 
or plain, but not striped. PUPA: perhaps with some metallic 
portions, but not totally metallic; head horns, various . . . B 
B. larva: scoli of A2-8 of similar form, although those of 
A2, and/or 7 & 8 may be longests. FOODPLANTS: non- 
rubiaceous C 
C. larva: pale grey or pale brown with sides of thorax 
through A2 much darker than rest of body; scolus of 
A2 long. PUPA: with huge, hook-like dorsal pro- 
jection from A2; head horns various 
(A. phylaca aethalia, melanthe, 
isis, mesentina , delphicola, (l)calliphiclea, (l)abyla) 
C. larva: dark, or not patterned as above; scolus of A2 
short, pupa: hangs tilted with ventral side superior; 
head horns short points bent sharply to sides 
( A . justina, jordani) 
B. larva: scolus of A2 different in form from scoli of A3-6 
(in A . iphicla the difference is merely the swelling at base 
of A2 scolus) foodplants: rubiaceous D 
D. larva: scoli of T2 or 3, and A2 & 7 swollen at base; 
(in A. iphicla, T2 & A2 only); face not patterned; head 
chalaza-1 not darker than others (don’t known for A. 
pseudococala). pupa: horns small, triangular “cat- 
ears” E 
♦The reader should bear in mind that in all Adelpha species, the scoli of T1 and A2 
are tiny.
