but strong; discal stria distinct in basal half , the sutural strong. Abdomen 

 slightly shorter and narrower than the elytra, the first segment deeply im- 

 pressed along the basal margin from side to side, the sulcus interrupted by two 

 cariniform bridges, separated by a little more than I3 of the total width. Legs 

 rather long and slender. Length 1.4 mm. ; width 0.55 mm. 



Yirginia (Norfolk). 



This species is narrower than minor, with slightly longer > 

 denser and more conspicuous pubescence and with the head nar- 

 rower, more elongate and less rapidly narrowed to the frontal 

 tubercle. In minor the transverse depression behind the tubercle 

 is near apical fourth, and, between the minute nude fovese and 

 each antennal tubercle, there is an extremely minute spicule, situ- 

 ated slightly nearer the tubercle than the fovea and arising from 

 the general surface without trace of a tuberculiform swelling. 

 The description and comparisons are drawn from the female. 



T. hexagonus n. sp. — Moderately ventrieose, strongly convex, polished 

 and impunctate, dark piceous when mature but frequently paler ; elytra, legs 

 and antennae always pale rufo-testaceous ; pubescence long, bristling and sub- 

 erect, rather abundant and conspicuous. Head small, very much narrower 

 and rather shorter than the prothorax, somewhat longer than wide, the base 

 rounded in circular arc behind the eyes, which are moderately developed and 

 prominent ; surface convex, the subfrontal transverse impression situated just 

 behind apical fourth ; frontal tubercles distinctly less than % the maximum 

 width, separated by a fine sulcus which angularly expands anteriorly ; puncti- 

 form fovese remotely separated, situated slightly behind the middle and exceed- 

 ingly minute, the spicules apparently subobsolete ; antennae not quite J^ as long 

 as the body, the basal joint long and cylindric, twice as long as the second and 

 almost as long as the next three combined, the second cylindric and obviously 

 elongate; three outer joints gradually larger; tenth nearly % wider than long. 

 Prothorax hexagonal, about as long as wide, widest and angularly rounded at 

 the middle, the sides thence straight to apex and base, strongly convergent 

 toward the former ; apex narrow, % of the maximum width and }4 ^^ wide 

 as the base; surface smooth and convex, with a coarse elongate furrow at each 

 side and a small fovea at the middle, all basal ; basal margin also with a 

 single series of small punctures. Elytra slightly shorter than wide, fully twice 

 as wide as the prothorax ; suture much longer than the humeral width ; sides 

 lather strongly divergent and broadly arcuate ; humeral prominences pro- 

 nounced ; surface convex, the discal stria coarse and deep, extending slightly 

 behind the middle, the sutural deep and broadly arcuate. Abdomen slightly 

 narrower and distinctly shorter than the elytra ; first segment slightly longer, 

 as usual, transversely rectilinear at apex, impressed along the basal margin, 

 the impression clothed with very short, subsquamiform, recurved setae. Legs 

 moderate in length, the femora somewhat inflated, the two anterior pairs 

 shorter and much less stout than the posterior. Length 1.4 mm.; width 

 0.6 mm.
