the second summer, the beetles emerging in August. The larva 

 is very quick and agile and when disturbed moves the hinder part 

 of its body quickly from side to side. When about to pupate "it 

 attaches itself firmly to a piece of bark by the thirteenth segment, 

 and the pupa remains attached by its anal segment to the larva- 

 skin." Perris (1876) believes that White is mistaken in his 

 account of the food-habits of the insect, and that it is carnivorous 

 or coprophagous, like Brontes planatus (q.v.). 



Emporius signatus Frauenf. — Imported into Germany from 

 the tropics in Havana cigars (Ganglbaur, 1899). 



Pediacus depressus Herbst. — Recorded from Europe, Van- 

 couver and the United States (So. Gala., Mich., Lake Superior, 

 Colo., Pa., S. G.) . In Britain under oak-bark, in mold-like fungus ; 

 also in stores on board a yacht (Fow^ler, 1899). Under bark of 

 deciduous trees in Germany (Reitter, 1911). 



Pediacus fuscus Erich. — Europe and North America, Alaska, 

 Labrador, British America, Mich., Neb., Golo., N. Mex., Lake 

 Superior, and probably cosmopolitan. In Germany under pine 

 and oak bark (Reitter, 1911), and under the bark of firs (Kalten- 

 bach, 1874). In Britain under bark and in chunks of freshly 

 cut oak, beech and horn-beam (Fovi^ler, 1889). 



Brontes planatus L. — Europe. Perris (1853) describes the 

 larva as livid reddish, punctate with carmine dots, and as being 

 very agile and supple. In France it is common throughout most 

 of the year under the bark of various trees, but most often 

 under oak or pine bark. Perris believes the larva to be carni- 

 vorous, because it is always found among the larvae of Tomicus 

 or with Poduri or mites 'dont elle fait, sans doute, sa nourri- 

 ture." "When about to pupate it attaches itself to a flat surface 

 by means of the tubercle of its last segment, then the skin splits 

 along the back and is pushed back to the posterior end of the 

 body, where it remains much wrinkled." In Germany under 

 bark of deciduous trees, especially of oaks (Kaltenbach, 1874; 

 Reitter, 1911) ; in Britain under bark of dead beech trees 

 (Fowler, 1889). According to Perris (1876) the larva is 

 predaceous and a scavenger, living under the bark of various 

 trees, including, chestnut, especially where the larvae of other
