anterior legs protecting the month parts, the pits to receive the anterior 

 knees, the character of hind coxal plates and the almost entire absence of 

 pubescence. 



O. glabratus Fabr. Ovate, black, moderately convex, shining, without 

 pubescence. Elytra uniformly black. Head coarsely punctate. Antennae 

 rufous, 11-jointed, bearing a 3-jointed club which equals about one-half 

 'the preceding part of the organ. Joints 1-2 moderately large, 3-8 small, 

 9 twice as long as any of the preceding and as wide as long, equaling 

 joint 10 ; the terminal joint is somewhat longer. Thorax coarselj' punc- 

 tate. Scutellum with a few fine punctures. Elytra entirely black, very 

 coarsely punctured, with a transverse depression across the basal third 

 and a fiiint vertical one on each side of the suture, on the apical half. 

 Body beneath black, coarsely punctate, abdomen rufous, lighter at the 

 edgesof the segments. Legsrufous. Length .12inch ; 3mm. (Figs. 79, 80.) 



There is but one species in our fauna, but the punctures on the thorax 

 vary considerably as to size and nun\ber, in the different specimens. "When 

 they are coarse and deep the insect is a true glabratus; when less coarse 

 we may regard it as the variety ater Er., and when relatively fine as 

 the variety subnitidus Lee. There are no characters of sufficient value to 

 enable us to separate these forms into different species. The larger speci- 

 mens, the second variety by the way, are from the Pacific, the smaller 

 from the Middle States.
