Report of the State Entomologist. 93 



This species has not yei, to my knowledge, shown itself as a museum 

 pest, feeding- upon objects of natural history, but it may become so 

 enrolled at any day, in the com])au3^ of two of its congeners — Ftinus 

 fur Linn., as recorded by Dr. Hagen,* and Ftinus quadrimaculatus 

 Melsh., from my own experience. Several examples of the latter were 

 discovered, dead, in the month of February, in a case of dragon-Hies 

 which had been received the preceding summer from South Bi'itain, 

 Conn. Two examples of the same had previously occurred in another 

 case of insects, in which they had evidently undergone their trans- 

 formations and committed some damage.

The Beetle Described. 



The following description of the beetle is that given by I'abbe Pro- 

 vancher, loc. ait. It is stated to be a common species

Brown, more or less deep. Front with two approach-

 ities. Prothorax with numerous transverse strite, sub- 

 cylindrical, with a sjDot at each angle not very distinct. ^ 

 "Wing-covers with two broad transverse bands, the lirst -^ 

 yellowish-white near the base, and the second, reddish- 

 w'hite at the extremity; this last with a black spot in 

 the middle, and the first often with a point mounting 

 to the scutellum, near the suture, and inclosing -p — xylo- 

 another detached spot near the shoulder. Feet red- tkechus colo-
