Pupa white when first formed, cast larval skin clinging tightly to last abdominal

 nated with a long, chitinized hook nearly reaching seventh abdominal segment. Meta- 

 thoracic tarsi extending well beyond tips of elytra. Head rounded, beak short and 

 broad. Head profusely supplied with hairs. Antennae nongeniculate, folded over 

 on dorsum, tips nearly meeting on metanotum. Prothorax profusely supplied with 

 long hairs, femora apically armed with several hairs. Mesonotum and metanotum 

 each provided with two bunches or tufts of long hairs. Elytra armed with numerous 

 hairs. Each abdominal segment is armed with two rows of dorsal, and numerous

Caulophilus latinasus (PI. 72) was described from Florida in 1831 by- 

 Thomas Say. This weevil is now widespread over the State of Florida and 

 has been reported from South Carolina and Georgia. It is also known to 

 occur in Jamaica, Porto Rico, Mexico, Guatemala, and Madeira. It is 

 doubtless common throughout the islands of the West Indies and in the 

 countries of Central and South America. 



It is commonly known as the "broad-nosed grain weevil," and is a 

 slender, elongate, reddish brown weevil with a short, broad beak. 

 Technical descriptions of the adult and immature stages follow. 



ADULT 



Elongate, rather robust. Reddish brown or piceous, feebly shining. Beak longer 

 than half the thorax, sparsely punctured, with a faint elongate fovea between the eyes. 

 Thorax as broad as long, moderately constricted near apex, sides strongly curved, 

 base slightly narrowed, feebly bisinuate; disk rather finely and evenly punctured, 

 with a broad, faint impression on basal third. Elytra subcylindrical, not wider than 

 middle of and more than twice as long as thorax, moderately convex; striae deep, 

 rather coarsely and closely punctured on basal half, more finely or obsoletely near 

 apex, the seventh and eighth united behind the humerus as in Allomimus: intervals 

 convex, indistinctly punctulate. Under surface sparsely punctured. Front tibiae 

 sinuate within. 



Length 3 mm. 3
