prominent; prothorax fully three-fourths wider than long, the sides 

 obtusely but subangularly prominent at the middle, thence sul parallel 

 and feebly sinuate to the base and converging and feebly arcuate to 

 the apex, the median line obsoletely impressed, deeply so anteriorly 

 and with a very feeble elongate central callus, densely punctate ante- 

 riorly, the basal fovea deep, single or double; punctures laterally coarse, 

 deep and confluent, with few irregular callous spots near the sides but 

 with more forming an irregular broken vitta at lateral fourth, the im- 

 pressions obsolete; elytra scarcely wider than the prothorax (c?), or 

 slightly wider ( 9 ), much more than twice as long as wide, the prolong- 

 ation generally very abruptly formed and parallel, broader than usual 

 though rather longer than wide; surface strongly, almost uniformly 

 punctate, densely and rugosely at the sides, with numerous callous 

 spots, which are elongate and regular suturally but elsewhere small, 

 very irregular and ramifying transversely and longitudinally, the areolae 

 not well defined and not more finely punctate; under surface as usual. 

 Length 14. 2-19.0 mm.; width 4.7-6.4 mm. Massachusetts. 



pisciformis n. sp. 



A — Similar to the preceding but narrower, paler and brighter cupreous, 

 the elytra with the elevations more uniformly elongate and regular 

 throughout and the sides more gradually converging posteriorly, with 

 the prolongations much less abrupt, more extended and very notice- 

 ably narrower in form, brighter cupreous in color; eyes more prom- 

 inent, especially in the male. Length 16. 5-1 7.2 mm.; width 5.3-5.8 

 mm. Massachusetts longicauda n. subsp. 



7 — Body moderately stout, convex, shining, cupreous with black elevations, 

 dark cupreous beneath; head moderately coarsely, very densely and 

 subevenly punctate, with a small transverse central callus, the eyes 

 rather small, moderately prominent; prothorax two-thirds wider than 

 long, the sides converging and broadly rounded anteriorly, gradually 

 becoming parallel and sinuate behind the middle; surface feebly im- 

 pressed and more punctured along the middle, deeply and more nar- 

 rowly impressed anteriorly, the two ante-scutellar punctures conspicuous ; 

 punctures laterally only moderately coarse, crowded but not confluent, 

 wth callous spaces and sublateral broken vitta nearly as in the preced- 

 ing, the impression obsolete; elytra at base wider than the prothorax, 

 the humeral angles well exposed; sides parallel, gradually rounding and 

 converging posteriorly from about the middle, becoming broadly, feebly 

 sinuate to the tip of the unusually acuminate prolongations, the latter 

 strongly carinate medially on the disk; surface much as in the preceding 

 species, the series of fine punctures readily traceable suturally; under 

 surface as usual. Length (d^) 13.2 mm.; width 4.5 mm. Massachu- 

 setts cupreola n. sp, 



A — Similar to the preceding but narrower and more elongate, the head 

 a little smaller, more coarsely, confusedly punctate, with the ramify- 

 ing interspaces broader and more ruguliform; eyes nearly similar 

 but scarcely so prominent; prothorax shorter and broader, not im- 

 pressed along the median line except anteriorly and more coarsely and
