Apical angles of the clypeus rounded 2 



Apical angles more than right but very distinct, not rounded 9 



2 Clypeal teeth approximate 3 



Clypeal teeth rather widely separated 8 



3 Teeth of the clypeal apex extremely approximate and in the form of 

 low rounded ridges. Body shorter and less convex than in relictus, 

 shining, black, with a feeble piceous tinge above, the under surface 

 and legs castaneo-rufous; head slightly more than two-fifths as wide 

 as the prothorax, shallowly and coarsely scabrous, the medially 

 interrupted transverse ridge acutely elevated, extending to the sides, 

 its anterior slope with small discrete punctures; clypeus gradually 

 strongly upturned apically, trapezoidal, its finely elevated side 

 margins higher basally; mentum finely scabriculate throughout; 

 prothorax one-half wider than long, convex, the sides parallel, be- 

 coming rounded and convergent in rather less than apical half, the 

 basal angles broadly rounded; base margined at the sides; punctures 

 sparse but rather strong throughout, not differing at all laterad; 

 scutellum ogival, with a few discal punctures in two clusters; elytra 

 but very little longer than wide, rather conspicuously inflated in 

 about posterior two-thirds, circularly rounded in apical two-fifths, 

 fully a fifth wider than the prothorax, the punctures sparse, rather 

 coarse but shallow, annulate, those in the four sets of geminate striae 

 more close-set, these striae evidently impressed, elsewhere confused, 

 mingled with very fine sparse punctules, especially toward the sides; 

 pygidium convex, finely scabriculate, becoming smooth and sparsely, 

 rather strongly punctate medially except toward base; larger claw 

 of the anterior male tarsi not long, stout, bent medially at more than 

 a right angle, the external outline evenly arcuate to the apex, which 

 is on the straight inner margin but not at all produced, the claw-joint 

 scarcely one-half longer than the fourth; anterior tibiae with a rudi- 

 mentary fourth tooth. Length (cf) 19.0 mm.; width 10.6 mm. 



New Jersey clypealis n. sp. 



Teeth of the clypeal apex clearly separated and acutely triangular. . . .4 

 4 Head very small, scarcely more than a third as wide as the prothorax. 

 Body elongate, parallel and subcylindric, not wider posteriorly, deep 

 polished black, the under surface and legs blackish-piceous; head 

 scabriculate, smooth and impunctate basally, the clypeus trapezoidal, 

 concave, with coarse isolated rugulosity, finely and closely punctate 

 on the anterior slope of the transverse ridges, which are strong and 

 subtuberculiform internally, gradually evanescent externally; sides 

 feebly sinuate except basally; apex strongly reflexed, the teeth high, 

 large and well developed; prothorax fully two-thirds wider than long, 

 the sides evenly and strongly arcuate throughout, gradually con- 

 verging apically, the basal angles more than right but not very 

 broadly rounded: base beaded only about the hind angles; lateral 

 bead thick, the inner gutter scabriculate; punctures as in the pre- 

 ceding but still stronger; scutellum moderate, with only two or three 

 punctures; elytra long, nearly a third longer than wide, two and 

 one-half times as long as the prothorax and not wider, parallel, 

 circularly rounded in apical two-fifths; sculpture nearly as in the
