of no doubt, although it is possible that the geographical 

 locality may be erroneous. 



Oligolinus n. gen. 



The same remark applies to this genus as to MicroUnus, as 

 stated above, and nothing is known of the unique type be- 

 yond that already published by LeConte. The original de- 

 scription is as follows : — 



Sabcylindrical, brown, shining, slightly hairy; head twice as long as wide, 

 convex, narrower in front, the base truncate, the hind angles strongly 

 rounded; upper surface distinctly but not densely punctured, with a 

 broad smooth frontal stripe; under surface sparsely, coarsely punc- 

 tured; antennae paler, a little longer than the head, the outer joints 

 gradually much wider; prothorax as long as the head but not narrower, 

 distinctly but not densely punctured, with a broad smooth dorsal 

 stripe; elytra spartely punctured, the sutural stria obsolete ; abdomen 

 finely, not densely punctulate, the tip and legs paler. Length 2.4 mm. 

 Florida (Enterprise; floridanns Lee. 



Mr. Schwarz, who captured the original type, states that 

 the only specimen of what Dr. LeConte described as Meto- 

 poncus Jloridanus, was found by him in the galleries of a 

 Tomicus (Ips) in the bark of yellow pine in 1875. It was 

 sent to LeConte as a new species of Leptacinus, but has 

 never been found again as far as known. All that he can 

 say from recollection is that the species may not be a true 

 Metoponcus. 



Subtribe Othii. 



The normal elytral suture, more widely separated antennae 

 and broad and subobsolete epistoraa, are the only really im- 

 portant characters distinguishing the Othii from the Xantho- 

 lini, but here the middle coxae are contiguous and the anteri- 

 or tarsi dilated as a rule, while in the Xantholini these charac- 

 ters are the marked exception; in addition to this, the sides 

 of the head behind the eyes are never modified as they fre- 

 quently are in the Xantholini. The sides of the prothorax 

 are nearly as in Xantholinus throughout, but the gular sutures 

 are more separated and more deeply impressed as a rule, 

 feebly arcuate and gradually converging to the base of the
