 fuscous; under surface and femora with numerous fuscous markings, the 

 buccuke, basal joint of beak, front margin of pronotum, sides of coxal 

 cavities, osteola and basal parts of tibia? and tarsi dull yellow. Pronotum 

 with sides sinuate near middle, disk uneven, thickly punctate. Scutellum

Lakeland, Moore Haven, Miami, R. P. Park, Ft. Myers and 

 Dunedin, Fla., Nov. 19— April 2 (W!S. B.). Agricultural Col- 

 lege, Miss. {Weed). Very common about Dunedin and Moore 

 Haven, and, according to the records, throughout Florida. Hi- 

 bernates in bunches of Spanish moss, beneath loose bark of 

 pine and under chunks along borders of ponds and lakes. Taken 

 in numbers in March and April by sweeping foliage of Compo- 

 sitse and other plants growing in mucky soil. Ranges from Con- 

 necticut and Maryland south and southwest to Texas and Mex- 

 ico, and on the Pacific coast from Washington southward. Our 

 eastern form was separated by Baker (1906, 135) as var. ala- 

 bamensis. Larger and more parallel than our other species, from 

 all of which except basalis it is easily separated by the form and 

 length of bucculae.

Oblong-oval. Dull yellow, mottled with fuscous, rather thickly 

 clothed with fine grayish-yellow prostrate pubescence; head except me-

 each side of middle and some spots near side margins black; femora 

 dotted with brown or blackish; base of tibia? and tarsi more or less fus- 

 cous. Third and fourth joints of antenna? subequal, the second longer than 

 either. Pronotum trapezoidal, sides straight, evenly converging from 

 base to apex; disk finely, unevenly, rather sparsely punctate. Scutellum 

 with transverse ridge and apical carina often subobsolete. Connexivum
