COLEOPTERA. 
23 
Antenna rather short, not reaching the posterior angles of the thorax, pale 
testaceous, with their 7th, 8th, 9th and part of 10th joints blackish ; four 
basal joints together subcylindric, the 1st the longest and thickest, clavate, 
the three following nearly equal, the 3rd nevertheless somewhat longer; 
5th and 6th wider, as broad as long, subconic; 7th to 10th (which are 
black) transverse, quadrate-subconic, successively broader, the first (or 7th) 
being half, the 9th and 10th twice as wide as long, though all of the same 
length (shorter than that of the preceding); terminal longer and narrower, 
subtrapezoidal, with its acute angle (or point of the apical truncature) 
turned inwards. 
Thorax subconic, nearly as long as the width of the base ; apex rather 
roundly truncate, three times narrower than the base; sides subemarginately 
dilated towards the posterior angles, which are very acute; base very ob¬ 
liquely produced towards the middle, deeply sinuate, margined, with the 
central lobe obtusely rounded, subtruncate; convex, having a longitudinal 
elevation separated by a thin longitudinal channel in the middle ; that ele¬ 
vation has its culminating eminence in front of the base, with a short ridge 
at each of its sides; each side of the thorax near the base has an elevated 
tubercle separated from the central elevation by a deep impression ; punc- 
tate-subrugulose, sides with distant deep punctures; pitchy black, covered 
with a dark brown pile; there is in the middle a large subcordate macula 
encircled by a thin fuscous margin, and many other small spots of yellowish 
pile; also six whitish minute spots, one on each lateral margin of the cen¬ 
tral macula, one on each side of the apex (these four spots placed quadran- 
gularly), and one in the middle of each indexed side, making together with 
the dorsal spots a transverse line, observable when the insect is fresh. 
Scutellum subsemicircular, blackish, covered with a light ashy pile. 
Elytra shortly ovate, together nearly as wide as long, deeply emargi- 
nate and sinuate at the base, where they have two tubercles on each, one 
between the 2nd and 3rd striae, the other (being the shoulder) .lateral, elon¬ 
gate, obsoletely and subobliquely continued inwards to the middle of the 
elytra; sides dilated in the middle, thence narrowed to near the apex, 
where they are narrower than at the base; apex of each elytron rounded, 
sutural angle obtuse; depressed longitudinally in the middle along the 
suture; remotely punctate-striate; pitchy, covered here and there with a 
brown, fulvescent, shining pile; interstices punctulate; 1st, 3rd, 5th and 7th 
narrower, unicolorous; 2nd, 4th, 6th and 8th wider, having detached white 
spots, of which the sub-basal and posterior form two irregular transverse
