East-Africa: Condo territory near Lake Nyassa (my coll.). 
Not closely related to any described species, but coming nearest in 
structure to H. viridescens Walk, (of which H. Erlangeri Schout. is a 
pale variety according to a cotype in my collection). 
Larva, 5 th (or 4 th?) stage: Ovate, dark blue, finely shagreened, the 
elevated disk of the venter smooth, lateral borders of prothorax almost 
from apex to near posterior angles broadly red, basal and apical margins 
of the abdominal segments above and a lateral median spot to each seg¬ 
ment flavo-testaceous, under-side of body with a large pale yellow median 
patch of the same extent as in the imago, last four ventral segments with 
a large transverse bluish black basal spot, that of the third smaller and 
paler, lateral parts of ventral segments with the basal and apical margins 
reddish, a pale yellow lateral median spot to each ventral segment, the la¬ 
teral slopes of both the tergal and ventral discal abdominal elevations 
brownish fuliginous; antennae bluish black, apex of third joint narrowly 
luteous (fourth joint lacking); rostrum black, base of second joint whi¬ 
tish; legs coloured as in the imago, but the yellow basal part of the femo¬ 
ra narrower and only a faint trace of the yellow annulation to the four pos¬ 
terior tibiae, all tarsi black. Head with a strong erect black lateral spine 
immediately before the eyes, juga a little longer than clypeus, narrowly 
rounded at apex, their lateral margins rather strongly rounded, 2d an¬ 
tennal joint (corresponding to joints 2+3 in the imago) as long as head, 
sulcated above, 3d joint more than half the length of 2d, bucculse low but 
percurrent, rostrum slightly longer than in the imago, first joint reaching 
apex of bucculse. Pronotum as long as head, lateral margins broadly re¬ 
flexed with a long black spine at the apical angles and a still longer one 
at the lateral angles and two somewhat shorter red spines between the ot¬ 
hers, basal margin broadly rounded. Scuto-tegmen with the tegminal 
part not quite reaching apical margin of 2d abdominal segment, the ba¬ 
sal half of its costal margin armed with three spines, between which the 
margin is finely denticulated, inner portion of tegminal part separated 
from the rest by a distinct suture. Abdomen with the lateral parts 
broadly depressed with a strong suberect black spine at the apical angles 
of the segments, the pair of trichobothria behind each spiracle distinct, 
the discal parts both on the tergal and ventral side convexly raised, the 
tergal elevation with a pair of spines on the 3d, 4th, and 5th segment, 
the spines of the 3d segment short and more distant from each other, pos¬ 
teriorly united by a straight transverse keel, the spines of the 4th and
