508 Mr. D@Bharp on some new 
that it may be placed at the head of the Hawaiian series 
of the genus; it consists of B. tinctus, B. proteinoides, 
B. inauratus, B. affinis, and B. bidens. I will take this 
opportunity of correcting an error that by inadvertence 
occurred in the ‘Transactions’ of the Society, 1879, 
p-. 85, with regard to P. proteinoides. The description of 
that species should have been placed before, instead of 
after, that of B. explanatus, and the expression “ allied 
to the preceding” refers not to B. explanatus, which 
belongs to another group, but to B. tinctus. The second 
new group must be established for the very remarkable 
B. blackburn. There can be little doubt that this will 
form a distinct genus from the other Brachypepli ; but 
at present I prefer to leave it as a group thereof, for 
I think that increased knowledge and material will lead to 
the arrangement of the Hawatian Brachypepli in several 
distinct genera, but this can be better done when the 
species are most of them known than when they are in 
large part stillunknown. The B. blackburni differs by its 
shining and glabrous surface, its slender legs, com- 
paratively narrow and convex form, by the slight con- 
striction of the head behind the eyes, and, most decidedly 
of all, by the elongation of the basal portion of the 
pronotum, which rests on the elytra, and which, instead 
of having a very fine indistinct basal margin, possesses 
a broad flat one. The antennal grooves on the under 
side of the head converge very little towards the middle, 
but extend nearly directly backwards. 
With regard to the other new species of Brachypeplus 
here described, it is only necessary to remark that 
B. vestitus is a very distinct species, apparently belong- 
ing to the B. discedens group, to which group must also 
be assigned B. metallescens and B. varius. B. guttatus 
and B. sordidus are very distinct species of the B. 
robustus group, while B. striatus and B. obsoletus belong 
to the group of B. omalioides and allies. 
Brachypeplus inauratus, n. s. 
Vix latus, parum elongatus, subdepressus, subopacus, 
tenuiter sed conspicue pubescens, fusco-testaceus, eneo- 
tinctus, antennis pedibusque sordide testaceis; pro- 
thorace transverso, fortiter crebre punctato, lateribus 
rotundatis ; elytris conspicue seriatim punctatis, inter- 
stitius obsolete punctatis; abdomine crebrius fortiter 
punctato. Long. 4, lat. 13 mm.
