continental distribution of warmth by the day. The moment of emerging is between 5 and 7 a. m.; for which 
reason freshly emerged insects, which without any instinct for shelter climb up anything their tarsi get hold of, 
are more frequently seen in the day-time than any other Iieterocera, sitting freely and visible from afar. The 
imago which has already been flying takes its rest in the day-time on the soil, rarely on trunks. It rests with 
its wings spread, somewhat like Geometrae ; its repose is not very tight; on being disturbed, the insects do not 
fly away, but spread their wings and are flapping with them backwards. The copula takes place between 8 and 
9 y 2 p. m., thus relatively early. The short proboscis (8—11 mm) looks like a diminutive proboscis of Acherontia 
and probably suffices for drinking. Duration of life': 10 (A) — 20 (2) days. They do not propagate much 
(44—131 eggs). 
wallichii. B. wallichii Gray (= spectabilis Hope, conchifera Btlr.) (56 C a) is discernible from the preceding one 
by vein 1 of the forewing bending off about midway between the upper cell-angle and the distal margin, the 
marginal bow of the median ocellated band below the costal margin being convex, returning proximad in small 
undulating bows. — In the larva the pronotum is in all stages yellow with black longitudinal streaks, in the 
early stage the horns of the 11th and 12th segments are erect. Pectoral legs glossy red-brown, with black 
shields. In the pupa of either sex the cover of the proboscis is as long as that of the forelegs. — Whether 
rufescen.s. rufescens Btlr. is an individual variation or a geographical form, cannot be decided owing to the inaccurate 
labelling of the specimens at hand. The author states them to be paler, the undulate lines above to be more 
delicate and therefore more remote from each other, the central belt much narrower, particularly in the centre 
with a thinner black edge; the black vein-spots are stated to be less numerous. — The Japanese japonica Btlr. 
is the northernmost isolated and very small vicarious form of wallichii (cf. Vol. II, p. 228, pi. 35 c).
