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, etc. 



It occurs in the southern United States, West Indies, Central and 

 South America, Liberia, etc. 



Tenebrionids ; Meal-beetles; Meal-worms, etc. 



This group is represented by the universally diffused Meal-worm 

 (Tenebrio molitor), fig. 157, and by several other species, among 

 which are Phaleria testaeea Say, found under decaying rubbish on 

 the sea-shore, and Blapstinus metallicus (Fab.) Lee, 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 ; antennae slightly clavate. Length, 5 mm . 



A species of Opatrinus and Diaperis affinis also occur com-

Flour Beetle. {Tribolium confusum Duv.) Figure L58. 



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 mm long, with the body flat- 

 tened, and the sides of the head angular, outside the eyes.
