laterally rather deeply sinuate. Body beneath coarsely but sparsely punctate. 

 Length .12 — .14 inch; 3 — 3.5 mm. 



Male. — The tarsi are scarcely at all dilated. The posterior femur has on the 

 lower edge at middle, a slight tubercle similar to that observed in the anterior 

 femora of some Cholevce. 



Female. — Tarsi slender. Femur simple. 



This species can only be mistaken for glohosa, but the less punctate 

 surface will readily distinguish it. 



In its distribution this species is more southern than glohosa, all the 

 specimens seen being from Virginia, Kentucky and Georgia. 



li. discolor Mels. — Hemispherical, very little longer than wide, piceous- 

 black above, rufo-piceous beneath, shining. Head and thorax impunctate, 

 the latter with rectangular hind angles. Elytra as wide as long, sides when 

 viewed laterally very feebly sinuate, surface with eight entire striae of moder- 

 ately coarse and rather closely placed punctures, the ninth stria distant from 

 the margin at base, confluent with it slightly behind the middle, intervals flat, 

 smooth, the alternate with distant coarse punctures. Body beneath obsoletely 

 sparsely punctate. Length .10 — .12 inch; 2.5 — 3 mm. 



Male. — Anterior tarsi moderately dilated, the first joint quite broad, middle 

 tarsi less dilated, posterior femora simple. 



Female. — Tarsi very slender. 

 Occurs from Massachusetts and Canada to Virginia. 



I*. Blanchardi n. sp. — Hemispherical, piceous-black, very shining. Head 

 very minutely punctulate. Thorax with hind angles rectangular, surface im- 

 punctate. Elytra scarcely at all sinuate when viewed laterally, surface with 

 nine entire strise of moderate punctures, not very closely placed, the ninth 

 stria being entire and equidistant from the margin in its entire length, inter- 

 vals smooth, shining, the alternate with distant punctures. Body beneath 

 sparsely punctate. Length .08 — .10 incli; 2 — 2.5 mm. 



Male. — Anterior tarsi very feebly dilated. Posterior femora with a minute 

 denticle at middle of lower margin. 



Female. — Tarsi slender. Femora simple. 



In this species the surface is quite as polished as in Phalacrus. 

 It could only be mistaken for discolor^ but the position of the ninth 

 stria would at once distinguish it. 



Occurs at Tewksbury, Massachusetts, collected by Mr. F. W. BlanchT 

 ard who recognized its value as a species. 



Ij. obsoleta. n. sp. (Blanchard mss.) — Oval, very convex, somewhat nar- 

 rower posteriorly, piceous-black, very shining. Head sparsely finely punctu- 

 late. Thorax very minutely and distantly punctulate, hind angles rectangular. 

 Elytra with the margin when viewed laterally slightly sinuate, the surface 

 with nine entire striae of rather fine confused punctures, having a tendency to 

 form double rows, the ninth although confused distant from the margin even 

 at its tip, intervals minutely sparsely punctulate, the alternate with slightly 

 larger punctures distantly placed. Body beneath sparsely punctate. Length 

 .08— .12 inch; 2—3 mm.
