"glossy.") 



Here belongs a single medium sized species having the thorax 

 short, broad, abruptly and strongly con- 

 stricted at apex; first joint of fnnicle as 

 long as the next four, club elongate-oval, en- 

 tirely pubescent; front coxse very remote; 

 prosternimi very large, flat, with two deep, 

 more or less coalescent fovese just behind the

557 (8907). MADARELLUS u.xnri.ATrs Say, 1823, 315; 

 ib'd, II. 177. 



Oval, somewhat wedge-shaped. Black, highly pol- 

 ished; thorax often red, very smooth and shining. 

 Beak slender, nearly one-fourth as long as body in 

 female, feebly curved, its sides finely and densely 

 punctate. Thorax two-thirds wider than long, strong- 

 ly convex, minutely and very sparsely punctate. 

 Fig. QJ. Dorsal and side Elytra narrower at base than thorax, sides distinctly 

 views, x 8. (After Felt.) converging from base to apex; striae very narrow, 

 deep; intervals very finely punctate, those of sides more distinctly and fine- 

 ly rugose. Length 2.7 4.7 mm. (Fig. 92.) 



Posey and Monroe counties, Ind. 

 Throughout New Jersey on wild 

 grape, poison ivy and Virginia 

 creeper; August 20 October. Uto- 

 pia and Dunedin, Fla., March 4- 

 28. Ifanges from New England, 

 Michigan and Kansas south to 

 Florida and Texas. The three speci- 

 mens at hand from southern In- 

 diana and those from Florida have 

 the thorax red, while one from 

 Ithaca, N. Y., is wholly black, thus 

 bearing out LeConte's remarks that 

 the former variety occurs more com- 

 monly in southern regions. Easily 

 known by its smooth surface and 

 wedge-shaped uudulatory elytra. 

 Felt (190G, 479) states that it 

 "bores woodbine in association with 



scarce; -June Tune 9.
