posteriorly and form a V, and there are also two yellow 
lines, which commencing in the middle of the side unite 
posteriorly in the middle of the base; the wide V thus 
made is united to the discoidal one by a line running 
along the margin. These yellow lines are all wanting 
in the female example, but this may be the result of 
accident. Length 7 lines. 
Hab. Sumatra (C. Curtis). 
This species is closely allied to M. picta, Guérin, and 
M. aurantiaca, Voll. It differs in having the femora and 
tibiz red, in having the pygidium entirely clothed with 
yellow; the thorax is very strongly lobed at the base, 
very slightly angular at the sides in the male; the 
clypeus is only in the least degree emarginate in front. 
Besides the yellow lines and the thorax, most of the 
punctures are filled with yellow. 
BRENTHIDA. 
Eutrachelus sumatrensis, n. s. 
Very close to H. Temminckii, Latr., and agrees with 
it in every respect except that the thorax is a little less 
broad and less rounded at the sides; the spots on the 
elytra are similarly placed, but smaller, and the sub- 
humeral one on the fifth and sixth interstices is absent ; 
the basal spot is only on three interstices; the discoidal 
spot is on the third and fourth interstices only; the 
posterior band is much narrower, especially towards the 
margin; at the apex there are only two elongate spots, 
one on the third interstice, the other on the eighth. 
Length 33 lines. Male.
