B. semiiiuliim, n. sp. — Oblong oval, black, clothed with pale cinereous 

 pubescence. Head black, opaque, finely punetulate. Antenna not as long as 

 head and thorax, black, basal joints piceous. Thorax wider at base than long, 

 sides very feebly arcuate and gradually narrowing to apex; base feebly lobed 

 at middle, coarsely punctured, sparsely pubescent. Scutelluin small, oval, 

 cinereo-pubescent. Elytra oblong, gradually wider to apex, moderately striate, 

 striae punctured, intervals flat, finely punctulate, with a row of distant coarse 

 punctures on each, and clothed sparsely with cinereous pubescence. Pygidium 

 oblong oval, sparsely punctured, cinereo-pubescent. Body beneath and legs 

 black, sparsely cinereo-pubescent. Length .06 inch ; 1.5 mm. 



One of' the smallest species known to me. Resembles some of the 

 diminutive forms of B. pauper cuius, but is more elongate and clothed 

 with coarse pubescence of an uniform cinereous color. 



Occurs over a wide extent of country, specimens being known from 

 Pennsylvania, Nebraska, Dacota and California. 



B. macrocerus, n. sp. — Oblong oval, black, moderately shining, sparsely 

 clothed with whitish pubescence. Head oval, black, opaque, densely punctu- 

 late. Antennae one-fourth longer than the entire body, slender, feebly sub- 

 serrate, black. Thorax slightly wider at base than long, sides feebly arcuate, 

 base feebly lobed at middle, surface opaque, densely punctured, very sparsely 

 pubescent with white. Elytra slightly wider at base than thorax, conjointly 

 nearly as wide as long, sides feebly arcuate, surface striate, striae punctured, 

 iutervals flat, finely rugosely punctured and very sparsely clothed with white 

 pubescence, with a more evident short line on the third interval. Body be- 

 neath black, sparsely pubescent. Legs black. Length .08; 2 mm. 



A very distinct and singular species, and may be known from any 

 in our fauna by the extreme length of the antennae. 



District of Columbia and Tennessee. Ulke. 



The following species are said to have been collected in California, 

 but from the fact that many of the species described by Boheman had 

 erroneous localities assigned them, it is probable that these too have 

 been misplaced. They are probably from the west coast of South 

 America.
