under the bark of trees (Fowler, 1889; Champion, 1896). "As 

 an instance of unusual trouble caused by this insect may be 

 mentioned the case cited by Taschenberg of the beetles having 

 invaded sleeping apartments adjoining a brewery where stores 

 were kept and annoying the sleepers at night by nipping them 

 in their beds" (Howard and Marlatt, 1896). 



Oryzaephiluti mercatoi- Fauvel. — The "merchant grain- 

 beetle," very similar to the preceding, cosmopolitan, and recorded 

 as living in and feeding on pea-nuts, English walnuts, wheat, 

 corn-meal, cereipo fruit (Myrospermum frutescens) , candle-nuts 

 (Aleurites moluccana), and dried currants (Guillebeau, 1890; 

 Chittenden, 1897, 1911). It has been taken under the bark of 

 plane-trees in France, in the neighborhood of mills (Guillebeau). 

 Champion (1896) records it as occurring in shipments of pea- 

 nuts at Rouen in company with another grain-beetle, the Tene- 

 brionid Palorus suhdeprensus Woll. "The close relationship of 

 mercator and surinaniensis makes reasonably certain their 

 identity as regards development, nor is it probable that they 

 differ in any degree in food-habits" (Chittenden, 1896). 



Oryzaephilus biconiis Erich. — Cosmopolitan, but less widely 

 distributed and more southern than surinaniensis. Lives and 

 breeds in wheat and dried figs in France; also taken in rubbish 

 at the base of fig-trees (Guillebeau, 1890; Chittenden, 1897). 



Oryzaephilus gossypit Chitt. — Cosmopolitan ; breeding in 

 cotton-seed (Chittenden, 1897). 



Silvanus bidentatus Fabr.— Europe and United States (N. 

 J., Ind., Conn., So. Cala., Fla.). Under chestnut bark in the 

 United States (Glover, 1869). Recorded as occurring under 

 bark of oaks and firs in England (Fowler, 1889), of firs in 

 Germany (Reitter, 1911), of poplars, elms and figs in France 

 (Picard, 1919). J. B. Smith (1909) records it as occurring 

 under bark throughout New Jersey, as not rare, and as taken 

 most of the season. According to Picard it has the same mode 

 of life as the species of Laemophloeus (q. v.). 



Silvanus gemellatus Duv. — Cuba and Southeastern States to 

 New York. Lives and breeds in maize in the field as well as in 

 granaries, also in wheat and over-ripe or dried fruits. It nearly
