Allied to M. albohumeralis sp. nov. and distinguishable by the 
white-scaled white dots. Rostrum at base with three indistinct 
dorsal] carine and there rather densely punctate; the remainder 
very finely and remotely punctate; first joint of funicle thicker 
and longer than second, third and fifth cask-shaped, slightly 
longer than thick, the last spheric, club two and one-half times 
longer than thick; thorax coarsely but not so densely punctate 
as in albohumeralis, each puncture bearing, behind, a setiform 
scale; on each side, nearer the sides than the middle line, a small 
whitish scale dot of the size of scutellum, a similar one occurring 
below the lateral margin; scutellum rounded quadrate, convex, 
shining dark brown; elytra one and one-half times as long as 
broad, coarsely punctate-striate, the punctures nearly as long 
as the intervals between them, sixth series with smaller punc- 
tures at base, seventh and eighth abbreviated near shoulder, 
first interval with a white basal dot, similar ones at apex of 
fourth interval, which is more convex, in the first quarter of 
fifth, and in the first third of seventh and eighth intervals, 
moreover with dispersed white specks of color and some granules; 
underside nut brown, the sides of metasternum with a white 
setiform scale in each of the coarsely cicatrized punctures; fem- 
ora before apex with a large white dorsal patch, with, at 
most, a small white dorsal stripe behind the middle; hind femora 
strongly clavate, the front edge of femoral tooth whitish. 
Mecistocerus pictithorax sp. nov., ¢. 
M. picticolli Pasc. similis, sed prothorace breviore, lateribus 
rotundatis, medio haud carinulato, isabellino-squamosus, protho- 
race dorso, margine laterali lato excepto, nigricante; elytris fu- 
scescenti variegatis, fascia subapicali undulosa, obsoleta, apice, 
spatio primo secundoque ad basin pallidioribus, fere isabellinis; 
scutello transverso-rotundato, glabro; elytris utrinque ad saturae 
basin subtumidis, sutura spatiisque granulis minutis, remote 
seriatis, setuligeris, plerumque squamositate occultis; tibiis 
posticis in triente apicali marginis antici longe albido-barbatis. 
Long. 7.5 mm., lat. 3. 
MINDANAO, Davao Province, Davao. 
Very similar to M. picticollis Pacs.** of which I have before 
me specimens from Java and Borneo, but the funicle is more 
robust, and the last two joints moniliform and thicker than long. 
Prothorax one and one-fourth times as broad as long, the dark 
dorsal patch trapeziform, without a central carina; scutellum
