FouikI under duhri? on tlie beach ; it ?onie\vliat resembles scitnlus 

 in foini of body, and more particularly in the two small f'oraniiniform 

 ])unctiires behind and ratlier distant from the mentuni tootli ; the 

 dental setae of the mentum are close to tiie base of the tooth and are 

 rather ap[»roximate. 



The impressed setigerous channel begun at the humeri and again 

 resumed toward the apices, is a generic character, but the short 

 oblique apical stria seems to vary somewhat in obliquity; in the 

 present species it is very widely divergent, while in gemellus it is 

 very close to the marginal channel. The curious punctures behind 

 the mentum tooth appear to be a characteristic of the broadly de- 

 pressed species allied to scltulus, there being no trace of them in 

 those species similar in form to incnri-iis or gemellus ; I have, there- 

 fore, restored Ciiaudoir's genus for the latter.

B. glosseilia n. sp. — Form robust, short, convex ; sides strongly arcuate. 

 Color above dark rufo-testaceous ; head slightly darker beneath, rufo-testa- 

 ceous ; abdomen piceous-black ; legs pale fulvous, antennae same toward 

 base, brownish toward tip; integuments very translucent and very highly 

 jiolished. Head short and robust, scarcely as long as wide ; eyes moderate, 

 rather prominent, very coarsely granulate ; iiiterocular surface feebly con- 

 vex, liaving an irregularly impressed very short channel on each side over 

 the eye, and attaining the epistomal suture ; anterior margin of epistoma 

 one-third as long as the distance between the eyes, broadly and feebly 

 sinuate throughout, angles extremely well marked and prominent, sides 

 thence widely divergcuit, deeply and evenly sinuate to the anterior limits of 

 tiie eyes ; epistoma but slightly wider than long, suture distinct, setae at 

 two-lifths its length from the anterior angles ; labrum very short, more than 

 four times as wide as long, finely rugulose anteriorly, broadly and feebly 

 sinuate throughout ; antennae distinctly longer than the head and prothorax 

 together, basal joint ratlier robust, first three joints sub-equal in length, 

 decreasing almost uniformly in thickness. Prothorax widest at nearly two- 

 fifths its lengtli from the apex, where it is much wider than the head, and 

 one-third wider than long: sides strongly arcuate, very feeV)ly convergent 

 posteriorly, where they become feebly sinuate for a very sliort distance in 

 front of the basal angles, the latter prominent and not at all rounded ; base 

 and apex about equal in length, both transverse and straight ; disk rather 

 feebly convex, except towar<l the apical angles where it is very strongly so, 

 having at each side, at two-fifths the length from the apex, a small erect
