prominulis, striis 1-3 intcgris crenatis ; propygidio fovcolalo ; 

 1° vcntrali abdominis segmento dense strigoso-punctato ; tibiis 

 anticis 4-dentatis. 

 L. 5| miU. 



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

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

 flexed 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, strite, 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 

 stride 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 rnesosternal stria interrupted, and the 

 first segment of the abdomen is conspicuously and densely 

 stiigose-punctate. 



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

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

 nent, and the first ventral segment densely sculptured.

Oblongo-ovatus, parum convexus, niger, nitidus; fronte stria in tegra, 

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

 externa laterali margini proxima, post angulos a margine parum

 dimidiata, suturali arcuata ; propygidio pygidioque punctulatis. 



L. 9-9i 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 7 and somewdiat 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
