Araecerus fasciculatus (PI. 71) was described in 1775 by DeGeer from 

 Surinam. It is thought to have originated in India, but now it is 

 cosmopolitan in distribution. This beetle, commonly known as the 

 coffee-bean weevil, is robust, dark brown, and clothed with mottled 

 light and dark brown pubescence. The beak is short and wide.

Ovate, convex. Dark brown to black or piceous, clothed with yellowish and dark 

 brown pubescence ; intervals of elytra alternately tessellate with brown and yellow- 

 ish; antennae, tibiae, and tarsi reddish brown, club fuscous; femora piceous at middle. 

 Thorax very finely and exceedingly densely punctate. Elytra with rows of fine, 

 close-set, feebly impressed punctures; intervals very finely and densely granulate- 

 punctate. Length 2.5 to 4.5 mm. 3
