lus feeble ; under surface finely and more closely punctured. Length 3.5 mm.; 

 width 1.7 mm. New York tessellata Mdsh. 



Oblong-oval, more convex, polished, black, the antenna: piceous toward base, the legs 

 dark testaceous, the elytral pale markings rufo-testaceous and together not occu- 

 pying as much area as the black ground, the subsutural pale .spot not extend- 

 ing behind the middle and not forming an obverted C-shaped macula ; antennte 

 nearly as in tessellata but black and stouter, the third joint very much shorter 

 than the next two combined ; prothorax much more convex, distinctly less than 

 twice as wide as long, the sides broadly arcuate, converging anteriorly, the prom- 

 inence before the middle almost obsolete ; apex much nanower than the base and 

 broadly sinuate ; punctures moderately coarse and sparse ; elytra nearly similar 

 in form and sculpture, as wide as the prothorax but only three times as long ; 

 under surface finely, sparsely punctate. Length 3.0 mm.; width 1.4S mm. 

 Pennsylvania variegata, sp. nov. 



3 — Body throughout nearly as in tessellata but black, the antenna; concolorous, the 

 periphery of the pronotum rather paler, the legs piceo-testaceous, the elytral pale 

 niaculation nearly similar but less extended, much less in area than the black 

 ground, the subsutural C-shaped marks before the middle much shorter and not 

 extending distinctly behind the middle ; antenna nearly similar in structure but 

 stouter, and with the third joint very much shorter than the next two combined ; 

 prothorax and elytra nearly similar in form, the former a little narrower at apex, 

 with the apical angles somewhat more advanced and much less broadly rounded, 

 the pubescence longer and more conspicuous ; lateral prominence before the 

 middle equally conspicuous and much more so than in variegata. Length 2.9 

 mm.; width 1.4 mm. Indiana. — Cab. Levette... maculata, sp. nov. 



In tessellata the male has a large and very abruptly limited deep 

 oval excavation, slightly wider than long, .occupying almost median 

 third of the fifth ventral, and extending from the apex almost to the 

 base, the bottom of the excavation polished, impunctate and glabrous, 

 with a very few piliferous punctures posteriorly ; in maculata it is 

 equally deep and abrupt but smaller, occupying about median fourth 

 and is more distinctly pubescent posteriorly; in variegata it is as large 

 as in tessellata or larger, but very much more shallow. 



Incolia, gen. nov. 



In this genus the body is much more elongate and less convex than 

 in either of the preceding, and differs greatly in abdominal structure 

 and somewhat in its finer sculpture ; in the form and structure of the 

 antenncX and prothorax it is nearly similar to Abstritlia. The single 

 species may be described as follows from the unique type, which ap- 

 pears to be a female : — 



Body elongate, parallel, feebly convex, polished, blackish, the antenntv toward base, 

 legs, limb of the pronotum and an indefinite oblique elytral streak, extending for
