570 Notes in 1887 upon lepidopterous larve, éc. 
does at the last ecdysis. In certain species of Ceratocampa, 
figured by Burmeister (Plate XX.), the pair of dorsal 
spines on each segment are moderately developed, while 
those upon the 2nd and 38rd thoracic segments, and the 
caudal horn, are slightly predominant (Ceratocampa 
wardu, C. principalis, and C. argyracantha, the latter 
upon Plate XXIII., fig. 7). In others again (C. imperialis 
and C. penelope, Plate XX.), the caudal horn and thoracic 
spines are short and inconspicuous, while the others are 
very small indeed. In C. phoronea, C. ixion, and C. 
Regalis, Plate XIX., the thoracic spines and caudal horn 
are very much developed, the others small. There are 
several spines on each thoracic segment in these species, 
but the dorsal pair upon the 2nd and 8rd thoracic seg- 
ments, corresponding to those upon the Ist and 8rd 
thoracic segments of Aglia, are much the largest. These 
spines on the 2nd and 8rd thoracic segments of the 
last-named species (C. Regalis) are immensely developed, 
but not proportionately more so than in Aglia. I have 
to thank Lord Walsingham for kindly sending me Bur- 
meister’s beautiful work. 
“Abbot and Smith, in their ‘ Natural History of the 
Rarer Insects of Georgia,’ have arranged the moths of the 
above-mentioned genera, immediately after the Sphin- 
gide, as if to express their ideas as to the mutual 
affinities. The first moth after the Sphingide is 
Phalena cecropia, of which the larva is another good 
example of the same kind of development. No spines are 
figured on the ist thoracic segment; while the caudal 
horn and the dorsal spines on the 2nd and 8rd thoracic 
segment are rather larger than the others, which are 
nevertheless distinct on all abdominal segments anterior 
to the 8th. In Phalana promethea, also figured by these 
authors, the five most prominent spines are also 
coloured differently from the others. 
An extremely interesting larva from Lake Tanganyika 
was kindly sent me by Dr. Sharp. It is probably allied 
to Ceratocampa, or it may be a Smerinthine larva, allied 
to Lophostethus. Three strongly-developed spines are 
present on each side of every segment, from the 2nd 
thoracic to the 7th abdominal, both inclusive. On the 
8th abdominal, the two dorsal spines are fused into a 
forked caudal horn, the only forked spine on the larva, 
and hence there are only five spines on this segment.
