LITHOCHARIS, 
L, tabacina, n. sp. (Fauvel MS.). Form elongated, sides parallel. Pubescence 
of elytra rather long, sub-recumbent, dense, fine, piceous, much more sparse on the 
head and prothorax, more sparse and longer on the abdomen. Head quadrate, eyes 
very moderately prominent, situated at twice their length from the posterior angles; 
interocular surface feebly and evenly convex, finely, evenly and extremely closely punct- 
ate, punctures shallow and variolate, almost coalescent; antennal tuberculation pro- 
minent; antennz as long as the head and prothorax together, slender, first joint as 
long as the next two together, second joint distinctly shorter than the third, joints five 
to ten nearly equal, about as broad as long, last joint longer and just perceptibly wider, 
Prothorax quadrate, smaller than the head; anterior and posterior angles rounded; 
surface punctured like the head; median line very fine and distinct. Elytra at base 
one-fifth wider than the prothorax, one-fifth longer than wide; sides parallel and very 
feebly arcuate; surface depressed, finely and somewhat transversely rugulose. Third 
and fourth ventral segment equal in width and as wide as the elytra, thence decreasing 
in width slowly anteriorly, rapidly posteriorly, fifth much the longest. Legs rather 
short and robust, slightly paler in color. Gular suture very strong posteriorly. Color 
throughout rather pale castaneous, elytra slightly paler. Length 4.5—5.2 mm. 
This fine species appears to be so common, that to leave it longer 
undescribed seemed to me inexcusable in the present state of the science. 
The color exactly resembles some of the darker shades of the cured to— 
bacco leaf. 
Dermestis Mannerheimu, Lec. This species is undoubtedly distinct 
from D. marmoratus, Say. 
The spines which so densely cover the middle tibize are long, acute 
and somewhat slender in the former, and very short, robust and rounded 
at tip in the latter. The first joint of the middle tarsus is distinctly 
shorter than the second in Mannerheimii and equal in length to the 
second in marmoratus, and the last joint is relatively longer and more 
slender in the latter, The club of the antenne is much narrower, less 
flattened, much paler in color and more uniformly clothed with velvety 
pubescence in the former than in the latter. ‘The sma'l punctures of the 
penultimate and antepenultimate segments of the abdomen in the male, 
are relatively much larger in Mannerheimii than in marmoratus; in former 
they are surrounded by a rather large circular area, totally free from 
pubescence, which does not appear to be the case in the latter. 
There are also differences in the form of the scutellum, depth of the 
depression at the base of the pronotum, position of the eyes, and also 
great differences in the size and in the color, length and density of the 
pubescence.
