dark bands at joints. Found by us in a dry calabash. The body 
exceeds the elytra, the latter are strongly sulcate, and each has two 
low subbasal bosses. 
It infests not only the coffee-bean, but also cocoa-beans; mace, ete. 
It occurs in the southern United States, West Indies, Central and 
South America, Liberia, ete. 
Tenebrionids ; Meal-beetles ; Meal-wormes, ete. 
This group is represented by the universally diffused Meal-worm 
(Tenebrio molitor), fig. 157, and by several other species, among 
which are Phaleria testacea Say, found under decaying rubbish on 
the sea-shore, and Blapstinus metallicus (Fab.) Lec., found in similar 
places, but less common. ‘The latter is ovate, shining bronzy black, 
with rows of punctate dots on the elytra; prothorax minutely punc- 
tate; antenne slightly clavate. Length, 5™™. 
A species of Opatrinus and Diaperis affinis also occur com- 
monly, according to Jones. Heilprin records Opatrinus anthra- 
cinus, on the authority of Dr. Horn.

Flour Beetle. (Tribolium confusum Duy.) Figure 158. 
Several small beetles occur here in imported flour and meal. One 
seems to be this species, which is often very injurious to flour and 
other prepared cereal foods in the United States, often doing much 
damage. The beetle is brown; 3 to 4™™ long, with the body flat- 
tened, and the sides of the head angular, outside the eyes.
