Coleopferological Notices, V. 475 



pubescence long, coarse, erect but sparse. Head scarcely perceptibly wider 

 than the prothorax, subquadrate, the upper surface smooth, even, not very 

 convex, with two strong nude fovese separated by one-half the total width ; 

 antennal tubercles wide and flat, each limited internally and posteriorly by a 

 short oblique impression ; eyes large, prominent, at fully one-half their length 

 from the base; antennae one-half as long as the body, fifth joint but slightly 

 wider than the fourth, eighth but little produced outwardly at apex. Protho- 

 rax fully as long as wide, widest and broadly rounded at the sides before the 

 middle, with a fine transverse fold before the base which is flexed abruptly 

 forward at right angles for a very short distance at its lateral extremities, the 

 right angles enclosing a small nude fovea ; two fovese at the basal margin at 

 each side deep and distinct. Elytra one-fourth wider than long, one-half 

 longer than the prothorax and more than twice as wide, convex, impunctate, 

 the sides broadly areuate ; humeri rather prominent and tumid. Abdomen 

 from above nearly as wide as the elytra but distinctly shorter, the basal seg- 

 ment forming one-half the length. Length 1.4-1.5 mm. ; width 0.65-0.7 mm. 



North Carolina (Asheville). 



I took a large series of this species in the mountains of western 

 North Carolina ; there is very little variation, but the female differs 

 considerably from the male, being smaller, unicolorous and darker, 

 and especially narrower, with shorter elytra and relatively longer 

 abdomen, the latter having the last dorsal acutely pointed as in 

 some species of Batrisus. The description refers to the male, the 

 anterior tibiae having a lamelliform external tooth at apical third, 

 the surface between this and the apex feebly impressed and with 

 a small central foveola which encloses a condensed tuft of setae ; 

 penultimate ventral with a large deep non-abrupt excavation, angu- 

 late and abruptly defined anteriorly. This species differs greatly 

 from hulbifer in the form of the tibial tooth, in addition to the 

 other sexual characters. 



Bryaxini, 

 RYBAXIS Saulcy. 



The species of this genus are not numerous, but appear to be 

 well differentiated from Bryaxis by possessing a deep groove on 

 the vertical flank of each elytron and a transverse biarcuate sulcus 

 joining the lateral pronotal foveae. Although the sulcus is perfectly 

 constant, exhibiting no tendency to vary in the direction of Bry- 

 axis, there is notable inconstancy in the median fovea, which may 

 be large and spongiose or completely obsolete, the sulcus then being 

 simply abruptly bent and very feebly dilated at this point. Rybaxis
