COLEOPTERA.

behind the eyes, sometimes meeting in a confused transverse line, and two 
posterior parallel vittae, black. Thorax more semiglobose-convex ; basal 
subduplicate striga as in that species, very broad, arcuate ; the two post¬ 
dorsal black tubercles above the basal striga and the two ante-dorsal 
black maculae larger; the infra-lateral one is also much larger. Scu- 
tellum having its tuberculiform apical black elevation larger and thicker. 
Elytra more strongly punctate-scrobiculate ; their black markings and 
tubercles are placed as in that species, but are generally larger, 
especially the tubercles, which are more obtuse. They stand as fol¬ 
lows:— 1st, one covering the humerus, which is less acute, indeed 
obtuse: 2nd, six tubercles, one basal, on the elevation of the third 
interstice (which is very oblique anteriorly), small, but very perceptible, 
while it is obsolete or null in Apod, gemmatus; another at the end of 
that elevated part of the aforesaid interstice, at the anterior fifth of the 
length, also small; a third inside of—and a little behind—the second, 
on the first interstice, somewhat behind the end of its anterior elevation 
(which is straight) at about the fourth of the length, subelongate; 
a fourth behind the third, very ample at the base, occupying the 
first and second interstices at the middle; a fifth a little smaller, behind 
the fourth, at the posterior third ; a sixth hardly tuberculiform (in 
Apod, gemmatus it is acute) at the posterior fourth, on the fifth and sixth 
interstices: 3rd, three maculae, one intra-lateral, a little above the 
middle, larger than in Apod, gemmatus; a second (wanting in the 
aforesaid) oftentimes large, in some reduced to several approximate but 
separate spots only filling the impressions; finally, a third apical. 
Pygidium punctate, with two basal intra-marginal black maculae, larger 
than in Apod, gemmatus. Pectus more coarsely and deeply punctate, 
basal black macula large, evidently more or less bordering upon the 
medi-epimera ; the posterior one very large, plagiform, covering the 
post-epiniera almost entirely (in Apod, gemmatus these two maculae are 
small and far from approaching to the epimera). Abdomen more 
evidently punctate, unicolor.
