March, 1896.] WiCKHAM, COLEOPTERA OF N. E. AMERICA. 4 7 



D. teter Bon. — Black, slightly shining, thorax broader in front 

 of middle and considerably narrowed behind, longitudinal median line 

 very deep. Elytra deeply striate, strice smooth, intervals regular, very 

 convex. The form of thorax gives somewhat the appearance of certain 

 Pterostichi. Length 20-22 mm. = .80-.88 in. 



Habitat : New York, Pennsylvania, Ohio, Maryland, New Jer- 

 sey, District of Columbia, Virginia, 



D. politus Dej. — Smaller, black, very shining, form resembling 

 that of teter, but the thorax is more nearly quadrate, being less narrowed 

 behind. The elytra are regularly, smoothly and deeply striate, the 

 humeral carina short and obtuse. Length 12-15 mm. = .48-.60 in. 



Habitat : New York, New Jersey, Pennsylvania, District of Co- 

 lumbia, Florida. 



Licinus Latr. 



Antennae with thre ebasal joints glabrous, eighth and ninth striae 

 of elytra distinct ; elytra strongly sinuate at apex, seventh interval not 

 carinate. 



L. silphoides Fabr. — Black, somewhat shining, thorax rounded, 

 punctate. Elytra with three rather faint costae, punctato-striate, inter- 

 spaces deeply and closely punctured. Length 14-15 mm. = .56-. 60 in. 



Habitat : Massachusetts. Not a true member of our fauna, be- 

 ing a European species. 



Badister Clairv. 



Small beetles of a form suggesting our common species of Agono- 

 derus. They differ from the three preceeding genera in having only 

 two basal joints of the antennae entirely glabrous. The eighth and ninth 

 elytral striae are not approximated, the third interval has two dorsal 

 punctures. A condensation of Dr. Leconte's table will suffice to separ- 

 ate the species of northeastern America as follows : 



Synopsis of Species. 

 Elytral striae deep, interspaces narrow, convex. Elytra rufo-piceous, darker behind, 



antennse and legs reddish notatus. 



Elytral striae fine, interspaces flat. 

 Elytra spotted. 



Prothorax, legs and elytra bright yellow, the latter with broad median band in- 

 terrupted at suture and an apical blotch iridescent black pulchellus. 



Prothorax black, legs and elytra orange, the latter with broad median band and 

 apical spot black, confluent longitudinally from 4th to 6th stria, maculatus. 

 Elytra not spotted, sometimes bicolored.
