 1" ventrali abdominis segmeuto dense strigoso-punctato ; tibiis 

 anticis 4-dentatis. 

 L. 5| mil]. 



Oval, rather convex, black and shining ; the head clearly 

 punctulate, frontal stria rather fine, complete, and retro- 

 ilexed anteriorly, median area lightly impressed ; the thorax, 

 stria complete, disk microscopically punctulate, lateral mar- 

 gins clearly punctulate, scutellar fovea round and well 

 marked ; the elytra, striae, outer humeral shortened at the 

 base, curved apically, inner humeral represented by a row of 

 fine points, 1-3 markedly complete, with somewhat crenulate 

 edges, 4-5 and sutural are vaguely shown by fine punctures, 

 behind the humeral angle there is a prominent boss and at 

 the apical edge of the elytra between the second and third 

 striee is a marked depression ; the propygidium is finely and 

 not closely punctulate, with two round very distinct foveas ; 

 the pygidium is finely and evenly punctulate ; the sterna are 

 clearly punctulate, the mesosternal stria interrupted, and the 

 first segment of the abdomen is conspicuously and densely 

 strigose-pnnctate. 



The above somewhat resembles 0. pulvinatus, Er., but the 

 third dorsal stria is complete, the humeral angle very promi- 

 nent, and the first ventral segment densely sculptured.

Oblongo-ovatus, parum convexus, niger, nitidus ; fronte stria Integra, 

 antice recta; pronoto lateribus fulvo-ciliato, stria interna integra, 

 externa laterali margini proxima, post angulos a margine parum

 dimidiata, suturali arcuata ; propygidio pygidioque punctulatis. 



L. 9-9^ mill. 



Oblong-oval, rather convex, black and shining ; the head 

 smooth or microscopically punctulate, stria well marked and 

 anteriorly straight; the thorax margined with a yellow pile, 

 external stria two-thirds the length of the thorax and hamate 

 behind the anterior angle, where it departs slightly from the 

 edge, internal complete behind the neck, markedly sinuous 

 laterally and somewhat distant from the edge; the elytra, 

 striae, inner humeral apical and passing the middle, dorsal 

 1-3 complete, 4 slightly abbreviated at the base, 5 less 

 marked and dimidiate, sutural is rather shorter than the 

 fourth and turns away from the suture at both ends; the 

 pygidia are finely punctulate, the points of both being larger
