Lecontia, Champ. 



L. discicoHis, Lee. (fig. 17), is blackish-piceous ; head coarsely close- 

 ly punctured, usually with a few irregular smooth spaces on the vertical 

 and occipital regions, sides behind the eyes nearly straight, slightly 

 convergent posteriorly. Antennns short, not reaching middle of thorax, 

 last three joints broader. Prothorax transverse, about one and a half 

 times as broad as long in the best developed specimens, wider 

 than the head, sides nearly or quite straight and parallel from 

 near apex to behind the middle, thence rapidly narrowing to 

 base ; surface coarsely, closely but unevenly punctured with 

 irregular smooth spaces on median area and a large illy-defined 

 central discal impression, on each side of which is a rather less 

 evident one. Elytra conjointly a little more than twice as long 

 as their width at base, sides nearly parallel to near the tip. Surface 

 rather shining, densely punctured, with several very slightly elevated 

 costfe. Legs short, concolorous with the body. Length of my speci- 

 mens varies from 10 to 20 mm. =.40-. 80 inch. The small individuals 

 resemble the next species very closely in general outline and appearance, 

 but may be readily separated by the shape of the head behind the eyes. 

 The larger individuals have the above-mentioned specific characters 

 much better developed than have the smaller ones. Beaten from pine 

 trees or found under bark. 



BoROS, Hbst. 



B. unicolor, Say, resembles L, discicollis in general form and colour, 

 but is usually much smaller and more shining. The head is much 

 narrower than the prothorax, distinctly constricted behind the eyes. 

 Antennae short, not reaching back to middle of prothorax, last three 

 joints broader, proportionately more so than in the preceding species. 

 Prothorax, by measurement, just perceptibly broader than long, densely, 

 coarsely and rather regularly punctured ; sides regularly rounded, no 

 discal impressions. Elytra elongate, more than two and a half times as 

 long as the breadth at base, sides nearly parallel to near the tip, only 

 slightly broader behind the middle, surface more finely punctured than the 

 thorax, punctuation close, without serial arrangement. Evidences of costa? 

 are very faint. Length, 1 1-12 mm. = .44-.48 inch. Found under bark.
