40 FAMILY II. AXTHRIBIDJE. 



sutural Hue and ''varieties occur in which the spots are obsolete, 

 and which are then separable from lintbatus only by the narrower 

 form and more elongate thorax." (LcConte.) Usually known as 

 B. variegatHS Say, but Jordan states* that this name was preoc- 

 cupied by Fourcroy (ITS.") for a European species. B. xticticiis 

 Boh. and B. obxolctiiH Fahr. are both synonyms, the former 

 having priority by six years.

Oval, robust. Dark reddish-brown, antennae and tibiae paler; terminal 

 joint of tarsi blackish and antennae fuscous at tip; above thickly covered by 

 short, fine, brownish or grayish-yellow hair. Thorax convex at middle,

 abundantly on ragweed. Ambrosia artemisicefolia L. 



30 ( ). BRACHYTARSUS PAULTJLUS Casey, 1884, 194. 



Oblong-oval, strongly convex. Black, above thickly clothed with fine 

 prostrate gray and brownish hairs, the latter more evident on middle of 

 disc of thorax and elytra, but more or less evenly intermixed with the 

 gray throughout the surface; beneath sparsely clothed with gray hairs; 

 tibiae, tarsi and basal joints of antennae pale reddish-brown. Head and beak 

 black, shining, very finely and densely granulate. Thorax at base slightly 

 wider than long, sides almost straight and evenly converging from base to 

 apex, the latter obtusely rounded and one-half the width of base; disc with 

 hind angles acute, the sculpture hidden by scales. Elytra oblong, sides 

 straight to apical fifth, then broadly rounded to apex; striae fine, rather 

 coarsely punctate; intervals feebly convex, minutely punctulate. Length 

 1.31.8 mm. 



Putnam < 1 o., Ind., Sept. 21. Taken from pod of the bladder- 

 nut, XtapJiyJca tri folia L. Described from Delaware. Casey re- 

 ports it also from Asheville and Black Mountains, North Caro- 

 lina. Placed as a synonym of tonicntosus by Henshaw, but in 

 our opinion a very distinct species.

Brownish-yellow or pale reddish-brown, clothed with short, pale yel-
