of the strial punctures being exactly equal in size and form to those of the 

 intervals. Abdomen finely, not densely punctate, the scales large and dense. 

 Presternum flat, separating the rather large coxae by not quite their own width. 

 Length 4.7 mm. ; width 2.4 mm.

Easily distinguishable from pruinosa by the dense vestiture of 

 broad recumbent scales. A single specimen. 



STICTOBARIS n. gen. 



The few components of this genus are distinguished by a rather 

 depressed body, extremely coarse and deeply perforate sculpture 

 of the pronotum, and a rather short prothorax which is strongly 

 tubulate at apex. The anterior coxae are large and somewhat nar- 

 rowly separated. Although the prosternum is feebly impressed, a 

 certain decided relationship with Onychobaris is rendered evident 

 by the two deep foveaa situated near the apex. It resembles Baris 

 in the large basal joint of the antennal club, though this is not a 

 character of decisive generic import, but differs from both the genera 

 referred to in the deep and abrupt transverse frontal groove or con- 

 striction. 



The beak is rather short and stout, with the epistomal lobe short 

 and broadly sinuate at apex and the mandibles somewhat well de- 

 veloped, arcuate, notched at apex and partially decussate when 

 closed. The vestiture consists simply of rather long sparse stout 

 semi-erect and whitish or yellowish- white setas or setiform squam- 

 ules, which are sometimes denser on the second to fifth elytral 

 intervals behind the middle, a character heretofore noticed in one 

 of the groups of Plesiobaris, and also occurring in several species 

 of Centrinus. 



The three know^n species may be thus distinguished : — 



Setae moderate in length, yellowish, condensed at the base of the third interval 

 and also on intervals two to five in a rather large area behind the middle ; 



body oblong ; legs rufous ...1 crlbrata 



Setae longer, more robust and whiter, not in the least condensed at the points 

 mentioned under the preceding species. 

 Body rather robust, oblong, obtusely rounded at apex ; beak densely punc- 

 tate ; legs black 2 pimalis 



Body narrow, rather narrowly rounded behind ; size much smaller ; beak 

 more sparsely punctate ; legs rufous 3 silbacilta
