PACIFIC SCIENCE, Vol. IX, April, 1955 
Southern atypical races and "palm-bract" race: 
Abdominal tergites always with broad apical 
light bands. Lateral light scaling of mesono- 
tum very conspicuous. 
pupa. — Pigmentation moderate, a reddish 
brown dorsally on cephalothorax, proximal 
abdominal segments, and intersegmental ab- 
dominal areas, remainder lighter (except in 
palm-bract race); trumpet a bright reddish 
brown; integumentary sculpturing distinct on 
more heavily pigmented areas. Trumpet index 
about 2. 8-3.0; width at basal 0.1 about 0.6 
of that at middle; pinna about 0.15-0.20. 
Hairs 5-IV-VI(l); 2-II-VII(l-7b); l-II(sim- 
ply branched ); 1 -I V-VI (variable). Paddle in- 
dex variable, length of paddle dependent on 
length of larval siphon; midrib narrow; inner 
and outer margins with spicules few and 
scattered. 
Typical race: Hair 2-II-VII multiple. 
Atypical races: Hair 2-II-VII single. 
LARVA. — Pigmentation of head and un- 
sclerotized integument of thorax and abdo- 
men a light reddish brown, except in "palm- 
bract” race. Head width about 0.96 of length, 
greatest width cephalad of eye; hairs 14-C 
(usually 2b, thickened), 15-C(usually 8,9b, 
long). Thorax and abdomen with conspicuous 
stellate tufts always well developed, usually 
with not less than 5 and no more than 25 
strong branches; large single hairs not swollen 
or fringed near base. Thoracic hairs: 1-P (vari- 
able, shorter than 3-P), 2-P(l, longer than 
3-P), 3-P(variable), 5-P(l, about twice as long 
as 2-P), 13-T(variable, only slightly longer 
than other ventral stellate tufts). Abdominal 
hairs: 2-I-VII, 0,14-II-VII stellate, well de- 
veloped; 10-I-VII stellate, well developed, 
comparable to other tufts. Comb scales, si- 
phon, index, pecten teeth, siphonal and anal 
hairs and anal gills extremely variable but not 
as in caledonica or folicola. 
Typical race: Hair 4-X about as long as saddle, 
usually with three or more branches; 1-X with 
five or more branches; dorsal anal gill about 
1.15 of saddle. Siphon index 3.6 to 6.0; dis- 
tance between 1-S and most proximal la-S 
distinctly greater than that between more 
distal la-S; usually 16 to 18 la-S, mostly 
3,4b; usually 13 or 14 2a-S, mostly 2b; pecten 
teeth 6 to 9, absent from basal fifth or more. 
Comb scales about 30, those at level of 5-VIII 
pointed apically and without distinct apical 
fringe; hair 1-VIII with about 16 branches; 
5-VIII multiple. Large dorsal stellate tufts 
of abdomen with 14 to 25 strong branches. 
Northern atypical races: Hair 4-X from 2.0 to 
3.0 length of saddle, usually 2b; 1-X usually 
2b; dorsal anal gill variable, often 2.0 of 
saddle. Siphon index variable, usually 2.5 to 
3.5; distance between 1-S and most proximal 
la-S as in typical race; usually 8 to 11 la-S, 
mostly 3,4b; usually 4 to 10 2a-S, mostly 
3,2b; pecten teeth usually 4 or 5, absent from 
basal fifth. Comb scales usually 20 or less, 
those at level of 5-VIII often blunt or rounded 
apically and with distinct apical fringe; hair 
1-VIII usually about 10b, 5-VIII usually 2b. 
Large dorsal stellate tufts of abdomen often 
less than 10b. 
Southern atypical races: Hair 4-X from 2.0 to 
3.0 length of saddle, usually 2b; 1-X usually 
2b; dorsal anal gill variable, usually less than 
2.0 of saddle. Siphon index usually about 3.0 
to 3.5; distance between 1-S and most prox- 
imal la-S about equal to that between more 
distal la-S; about 15 la-S, mostly 2b; usually 
10 2a-S, mostly 2b; pecten teeth about 6, 
usually present in basal fifth. Comb scales 
about 30, those at level of 5-VIII blunt or 
rounded apically and with distinct apical 
fringe; hair 1-VIII about 16b; 5-VIII 3-6b. 
Large dorsal stellate tufts of abdomen usually 
10-20b. 
Palm-bract race (New Caledonia): Similar to 
southern atypical races except that dorsal anal 
gill is 3.0 or more saddle length, pecten teeth 
usually restricted to basal half of siphon and 
comb scales at level of 5-VIII with pointed 
apex. Pigmentation lighter than in other races.
