the eastern intertropical islands, from the Philippines to Tahiti, but, 
according to Mr. Pascoe, not met with by Mr. Wallace. 
SPHINGNOTUS DUNNINGI, Pascoe, Trans. Ent. Soc. 3rd ser. iii. 
p- 484, pl. xviii. f. 4. 
A single example, male, which, on account of the identity of its 
peculiar coloration and general structure, may be referred to this 
species, of which ‘only one specimen is known. Our insect differs 
from Pascoe’s figure (representing probably the female) in its broader 
head, rather longer thorax and more parallel-sided elytra, characters 
which are generally found to be distinctive of the male sex in the 
Longicornia. 
PELARGODERUS AROUENSIS.

The species was previously recorded only from Aru and Saylee. 
BATOCERA BROWNI, n. sp. (Plate XXV. fig. 1.) 
B. wallacei (Thoms.) affinis. Magna, robusta, supra pube 
cinerea vestita ; thorace immaculato; elytris tuberculis nitidis 
sparsissimis a bast usque ultra medium notatis, utrinque lineis 
duabus paulo elevatis, interstitiis densius tomentosis, apice 
breviter sinuato-truncatis, angulo suturali dentiformi. 
3. Antennis longissimis, validis, tuberculato-asperatis ; art. 
tertio valde elongato et robusto, pedibusque anticis denti- 
culato-asperatis. 
Long. 36 lin. 
Distinguished from all the varieties of B. wallace: that I have 
seen, by the whole body, above and beneath, being clothed with ashy 
white pubescence, three macular streaks down each elytron being 
formed of more dense felted tomentum of an ochraceous tint, and the 
flanks of the body having the usual chalky-white vitta; also by the 
very different tuberculation of the elytra, which consists in a number 
of small, widely scattered, black tubercles, spread over the whole 
surface except towards the apex, where the derm is coarsely reticulate- 
rugose, and where the dense tomentum conceals the integument. 
Besides these scattered tubercles, each elytron has two fine raised 
shining lines, apparently formed of tubercles arranged linearly. The 
outer angle of the apical truncature of the elytra is rounded, and not
