COLEOPTERA. 53 
throughout, the anterior border of the head is emarginated, and the 
three last penultimate joints of the antenne are almost globular, and 
not sensibly transversal *. 
Uris, Fab. 
The thorax as in Calear; the body narrow, but not linear; anterior 
edge of the head straight and unemarginate; penultimate joints of 
the antenne lenticular and transversal +. 'The 
Teneprio, Lin., Fab., 
Or Tenebrio properly so styled, only differs from Upis in the 
thorax, which is more broad than long. 
T. molitor, L.; Oliv., Col., II, 57, 1,12. Length seven lines; 
brown, verging on a black, above ; maronne and glossy beneath ; 
thorax as wide as the elytra; square, and with two posterior 
impressions; elytra striate and punctured.—Very common, in 
the evening, in the less inhabited parts of houses, flour-mills, 
bake-houses, on old walls, &c. 
Its larva is long, cylindrical, of an ochreous yellow colour, 
scaly, and very smooth. It lives in bran and flour, and is given 
to the Nightingales. It becomes a chrysalis in the midst of the 
substance on which it has fed. 
T. grandis, which is found in Brazil, under the bark of old 
trees, darts a caustic liquid from its anus to the distance of more 
than a foot. Other but smaller species from the same country 
completely cover themselves with this material. For these ob- 
servations I am indebted to M. de la Cordaire f. 
There, the penultimate joint of the tarsi is very small, in the form 
of a little knot, and received into a longitudinal groove in the pre- 
ceding, which is more dilated, and almost cordiform. 
The anterior edge of the head presents an emargination occupied 
by a portion of the labrum. 
Hererorarsus, Lat. 
A subgenus founded on an Insect from Senegal, having all the 
characters of a Tenebrio, but with singular tarsi. At the first 
glance, the two anterior ones appear to consist of but four joints, 
and the two others of three. 
FAMILY II. 
TAXICORNES. 
In this second family of the heteromerous Coleoptera, we find no 
small corneous tcoth on the inner side of the maxille. All these

} For the other species, see Catalogue, &c., Dej., and Fabricius. This genus, 
however, as now composed, needs depuration; several of its species belong to 
Phaleria, or other subgenera. Some of them may even form new ones.
