New York to Nova Scotia, and westward into the Lake Superior 

 i egion. That one or both of these should extend their range across 

 the continent to the Pacific coast would be entirely in accord with 

 the well-known tendency of boreal insects. The discovery of a 

 representative of the genus in California would lead one to sus 

 pect a form or climatic variation of one of the Eastern species. 

 A careful comparison of the abundant material now at hand 

 seems, however, to establish the fact that the Californian Brathi- 

 nus which is herein described is specifically distinct. 



TABLE OF SPECIES. 

 Maxillary palpi long: 



Last joint of palpus longer than the second joint; 



body glabrous: antennae slender, unicolored nitidus, Lee. 



Last joint of palpus as long as the second joint; 

 body pubescent; antennae stout, suddenly en 

 larged and pale at tip varicornis, Lee. 



Maxillary palpi short: 



Last joint of palpus shorter than the second joint; 



body pubescent; antennae stout, unicolored californicus, n. sp. 



In the foregoing table I have called the maxillary palpus long 

 if when directed forwards the second joint passes the mandibles, 

 and short if trie second joint does not project beyond the mandi 

 bles. 



Brathinus nitidus, Lee. This is our largest and most slender species. 

 The body is glabrous, light or dark brown, paler beneath. Antennae very 

 long, filiform, joints from the fourth opaque, finely pubescent; the last 

 three joints not larger and scarcely paler than the preceding joints. The 

 palpi are very long and slender; the first joint very minute, the second 

 joint greatly prolonged beyond the mandibles, the third joint half as long 

 as the second joint, the fourth joint longer than the second joint. Length, 

 5mm. 



Brathinus varicornis, Lee. The smallest species. Elytra with sparse 

 fine setae placed in four lines. Legs pubescent. Antennae stout, shining 

 toward the base ; from joint four gradually more opaque and more densely 

 pubescent, the last three joints suddenly enlarged and pale in color. The 

 maxillary palpi are elongate, the second joint passing the mandibles, the 

 last joint as long as the second joint. Length, 3.6 mm. 



Brathinus californicus, n. sp. Dark brown, shining; elytra with sparse 

 setae; antennae moderately long, robust, reddish brown; underside dark 

 brown; legs pale testaceous, pubescent; maxillary palpi short, last joint 

 stout, fusiform. Length, 4 mm. 



The elvtra bear four rows each of short setae, there are no striae, but the 

 suture is somewhat elevated throughout its entire length. The thorax in
