188 Mr. H. E. Andrewes’ Notes on Synonymy 
Prothorax transverse (1:30 x 1:75 mm.), moderately convex in 
front, about equally contracted at extremities, but widest at a third 
from apex, which is strongly emarginate, base truncate but with 
oblique sides, sides well rounded in front, then straight to base, 
the oblique sides of which they join at an obtuse angle, strongly 
reflexed, a setiferous pore at hind angle and another at about a 
third from apex; median line faint in front, deep behind, basal 
foveae deep, rounded, surface smooth, with some faint transverse 
wrinkles, base subrugose. Elytra elongate-oval (2-3 x 4-2 mm.), 
finely striate, intervals quite flat, 3 with two pores at about a third 
from base and apex respectively : front fascia occupying the whole 
of the basal fourth of the elytra, and extending a little way 
back along the suture, hind fascia narrower, but widening out 
at the suture and sometimes interrupted on the middle of each 
elytron. 
Allied to the Japanese B. pictus Bates, but larger and 
more iridescent: head larger and eyes more prominent, 
prothorax wider, its sides straighter behind, hind angles 
less obtuse and more strongly reflexed, elytra wider, more 
finely striate, the yellow fasciae and coloured sutural area 
much narrower. 
Omophron vittatus Wied. Length 5°75 mm. 
Pale straw colour: antennae and sides of prothorax dull orange, 
underside brown, the epipleurae of elytra and prothorax, and last 
two ventral segments rather lighter; transverse patches on back 
of head and middle of prothorax, both projecting forwards at 
middle, and a series of stripes on elytra dark green. These stripes 
occupy intervals 1, 2, 4, 6, and 10 from base to near apex; on 8 
there are two short patches of colour, one at about a third from 
base, the other rather longer just behind middle; a stripe on 12 
commences at a little distance from base and stops some way 
before apex, being interrupted at a fourth from base and just behind 
middle. 
Head finely striate near eyes, coarsely but not closely punctate 
behind, the subocular ridge taking the form of a fine furrow with 
one or two coarse punctures, the surface close to the eyes coarsely 
punctate. Prothorax bisinuate in front, quadrisinuate behind, 
increasing gradually in width from apex to base; surface finely 
rugose-punctate, smoother at sides. lytra with fifteen punctate 
striae, intervals smooth and shiny; only striae 1 and 2 reach the 
apex, 3 and 4 coalesce and join 2 near apex, 5, 6, 9, 10, 12, 13, 14, 
and 15 all end separately at some distance from apex, 7 and 8 are
