with a sutural and two or three dorsal striae, the sutural deeper behind, the outer 

 ones feeble or uearly obsolete: first dorsal puncture about one-third from base. 

 the second about one-fifth from apex. Body beneath piceous. Legs testaceous. 

 Length .12 13 inch : 3-3 25 nun. 



In the males the first two joints of the anterior tarsi are dilated. 



Most closely allied to ventricosus, but abundantly distinct by the 

 characters given above. The silken lustre on the elytra is very 

 marked in most examples seen, and is apparently due to their being 

 finely alutaceous. 



It seems to be confined to the extreme southern portions of the 

 country, being known to me only from Florida and Louisiana. 



36. T. ventricosus Lee. — Form slightly convex. Head and thorax brown. 

 slightly reddish, the elytra darker ; surface shining. Head as wide as the thorax 

 at apex ; eyes large and prominent; antennas about one-half as long as the body, 

 fuscous, slightly paler at each end; palpi rufo-testaceous. Prothorax subquad- 

 rate, about one-half wider than long, slightly narrower at base than apex ; apex 

 truncate: median line fine, extending between the transverse impressions, which 

 are distinct, the posterior deeper; basal impressions small; base truncate, 

 obliquely so each side ; sides with the margin very narrowly reflexed, arcuate in 

 front, oblique behind, rarely very feebly sinuate in front of the hind angles, 

 which are obtuse, but not rounded, not carinate. Elytra nearly oval, about one- 

 half wider than the thorax, the sutural stria deeper behind, the second moder- 

 ately distinct, the others nearly effaced ; strise impunctate; dorsal punctures dis- 

 tinct, the first about one-third from base, the second about one-fifth from apex. 

 Head and thorax beneath reddish brown, the abdomen more or less piceous. Legs 

 testaceous. Length .09. 10 inch ; 2.25-2.5 mm. 



The first two joints of the anterior tarsi are dilated in the males. 



Smaller and more robust than the preceding. The color is also 

 different, and no trace is visible of the silken lustre so marked in 

 albipes. The hind angles of the thorax are somewhat prominent, 

 although obtuse. On the whole it is one of the best defined species 

 of the group. 



T. oopterus Chaud. is synonymous with this species. 



Like the preceding it is confined to the extreme Southern States. 

 It occurs in Louisiana and Florida. 



37. T. latipeimis n. sp. — Form broad, depressed. Color rufo-testaceous. 

 shining, thorax slightly paler. Head as wide as the thorax at apex ; eyes large 

 and prominent; antennas less than one-half as long as the body, testaceous; palpi 

 testaceous. Prothorax twice as wide as long, as wide at base as apex, subquadrate ; 

 apex truncate; median line fine, extending between the transverse impressions, 

 the anterior of which is nearly obsolete, the posterior distinct ; basal impressions 

 small ; base truncate, obliquely so each side : sides with the margin very narrow ly 

 reflexed, arcuate in front, oblique behind; hind angles very obtuse, slightly 

 rounded, not carinate. Elytra oblong-ovate, more than one-half wider than the
