184: H. C. FALL. 



than in carinatus. First and fifth ventral segments suhequal, the second evi- 

 dently longer than the fifth. Otherwise very nearly as in carinatus. Length 

 2.2-2.8 mm. 



Ithaca, New York ; Toronto, Canada; Pennsylvania; Cincinnati, 

 Ohio ; Dane County, Wisconsin ; Tennessee ; North Carolina. The 

 first ventral suture is obviously though feebly posteriorly arcuate at 

 middle, thus slightly narrowing the second segment, agreeing in 

 this respect with Anobium striatum, to which species it otherwise 

 bears a very striking resemblance. 



5. H. laticollis n. sp. — Brown, a little stouter than carinatus, the prothorax 

 fully equal in width to the elytra at hase. Eyes ( % ) moderately large, separated 

 on the front hy rather less than twice their vertical diameter. Antennae 11- 

 joiuted, first joint of club parallel, three times as long as wide, and equal in 

 length to the seven preceding. Prothorax a little more strongly gibbous than in 

 carinatus, sides moderately convergent in front; margin fine and somewhat ill 

 defined in front, becoming more pronounced and a little explanate at the hind 

 angles, which are rounded as usual ; surface finely not closely granulate-punc- 

 tate, a subobsolete impressed line from the. front margin to the summit of the 

 gibbosity. Elytra finely punctate-striate, the interspaces much wider than the 

 rows of punctures; apex narrowly but evidently truncate. Second ventral seg- 

 ment just visibly shorter than the fifth ; first suture straight. Length 3.8 mm. 



California (Castle Crag). A single male collected by Dr. Fenyes. 



6. H. umbrosus n. sp. — This name is given with some hesitation to a 

 rather large blackish form, with 11-jointed antennae, which resembles in nearly 

 every particular the large dark forms of carinatus. The sides of the prothorax 

 are straight and moderately convergent anteriorly, without post apical sinuation. 

 The second ventral segment is equal in length to the fifth, the first suture just 

 visibly arcuate at middle. Length 5.1-5.5 mm. 



AVhite Fish Point, Lake Superior; New York; North Conway, 

 New Hampshire (Blanchard). 



Three examples from the first named locality in the Hubbard and 

 Schwarz collection are taken as types. In one of the New York 

 specimens the sixth and seventh joints of the antennae are com- 

 pletely connate, but with the line of junction plainly indicated. It 

 is possible that in a large series the number of joints will be found 

 to vary as in Oligomerus obtusus, and that umbrosus is only an ex- 

 treme form of carinatus. 



7. H. gibbicollis Lee. — Varies in color from brown to piceous; pubescence 

 longer than usual and more or less evidently condensed on alternate intervals of 

 the elytra, these intervals being also a little more convex. Prothorax much nar- 

 rower than the elytra, as long as or a little longer than wide, base and apex of 

 equal width, the sides nearly parallel and Insinuate; front angles well defined,
