Female. — Moderately elongate, moderately convex above, rather strongly 

 shining, dark bronzy green, with a faint cupreous reflection; beneath purplish 

 brown, with a distinct bronzy-green tinge, and more strongly shiuing than above. 



Head bronzy black, with a distinct purplish tinge, shallowly, broadly depressed 

 on vertex, with a narrow, longitudinal carina on occiput, the carina bifurcate 

 anteriorly; front slightly convex; surface glabrous, coarsely, deeply foveolate- 

 punctate on front, more finely punctate on occiput ; clypeus sinuate in front, with 

 a broad, median tooth. Eyes separated from each other on the top by about one- 

 fourth their width. Antenna short, purplish brown on basal segments, greenish 

 black on apical segments; fourth segment strongly triangular, nearly twice as 

 wide as the third ; outer segments compact, strongly transverse, broadly rounded 

 at outer margins, and each with a short, whitish hair ; third segment as long as 

 the following two segments united. 



Pronotum twice as wide as long, narrower at apex than at base, widest at 

 middle; sides slightly, arcuately rounded, more strongly toward apical angles, 

 vaguely sinuate at posterior angles, which are nearly rectangular; base trans- 

 versely sinuate on each side, the median lobe slightly produced and very broadly 

 rounded; disk moderately convex, broadly, transversely depressed behind the 

 middle, without distinct prehumeral carinae ; surface glabrous, closely, deeply, 

 transversely rugose, coarsely punctate between the rugae. Scutellum bright 

 green. 



Elytra distinctly wider than pronotum, twice as long as wide; sides parallel 

 from humeral angles to middle, then strongly converging to the tips, which are 

 separately, rather acutely angulated ; basal depressions broad and shallow ; sur- 

 face slightly uneven, glabrous, densely, finely, uniformly scabrous. 



Abdomen beneath glabrous, finely, sparsely punctate, transversely rugose at 

 sides, smooth along anterior and posterior margins of sternites, the intervals 

 obsoletely granulose ; last visible sternite strongly depressed, broadly truncate at 

 apex, with a strongly elevated, serrate, preapical ridge; eighth tergite broadly 

 rounded at apex, slightly, longitudinally carinate at middle, lateral margins 

 strongly elevated, the surface finely punctate, densely granulose, and sparsely 

 clothed with long, erect, black hairs. Prosternum glabrous, densely, coarsely 

 punctate, transversely rugose anteriorly ; anterior margin truncate. Tibiae 

 straight or slightly sinuate, unarmed on inner margins. 



Length 14.5 mm., width 6 mm. 



Redescribed from a female in the United States National Museum, 

 collected in Lake County, Ind., June 17, 1903, by W. S. Blatchley, and 

 donated to the Museum by J. J. Davis, Since the type of this species 

 is lost, the writer is designating this specimen as the neotype. 



Male. — Differing from the female in having the hairs on the antennal segments 

 much longer, and the middle and posterior tibiae armed with a number of small 

 teeth on their inner margins. The sexes are very much alike. 



Type locality. — Of acornis, Indiana ; type lost, neotype in the United 

 States National Museum. Of punctata, Pennsylvania; type probably 

 specimen No. 6 under acornis in the LeConte collection. Of rugosula, 

 North America; present location of type unknown to writer. Of 

 calif ornica, "Nova-Helvetia," Calif, (present site of Sacramento) ; 

 type supposed to be in the Moscow Museum. 



Distribution: — Material has been examined from various localities 

 in the following States : Florida, Indiana, Iowa, Louisiana, Michigan, 

 New Jersey, New York, Ohio, Pennsylvania, Texas, and Virginia. 

 Chamberlin (1926) also records the species from Kentucky and Wis- 

 consin, Ulke (1902) from the District of Columbia, and Brimley (1938) 

 from North Carolina. 



Hosts. — Knull (1920, 1922) records rearing adults from dead wood 

 of red maple (Acer rubrum Linnaeus), beech (Fagus grandi folia
