flat, the labrum wide, lower front paler than upper. Antennae in 

 male 10-jointed, basal three joints pale with dark edges, the re- 

 mainder piceous, joints 3-5 long, rest gradually diminishing in length. 

 In female, antennae 11-jointed, joints 2, 3 short, subcqual, remainder 

 longer and subequal. Prothorax a little wider than long with nearly- 

 straight sides, disk with a faint semicircular depression in basal half, 

 sides widely piceous, margins, base and median space pale yellow, 

 shiny, punctate on sides. Scutellum pale. Elytra with small humeri, 

 elongate and narrow, alutaceous but shiny, piceous except for pale 

 lateral and sutural margins; in some western specimens (nigripennis) 

 elytra entirely dark. Body beneath, except tip of abdomen, and legs 

 pale; middle tibiae of male notched near apex, and tibiae with fine 

 spine, claws appendiculate. Length 3-4 mm., width 1.4-1.8 mm. 



Type: A male in the LeConte collection, bearing a pale scarlet 

 round locality label signifying the Southern States. There are two 

 others with similarly colored labels, a male and female. The type of 

 Phyllecthrus nigripennis is a male from "Ks." Two others, bearing a 

 similar locality label, are females (?).

Remarks: Horn reduced P. nigripennis LeConte to a variety of 

 P. gentilis. Comparison of the two types in the LeConte collection 

 shows that the two are very much alike except that nigripennis is 

 darker in coloring, having the elytra entii'ely dark, and the abdomen 

 dark, the breast not so dark, the epipleura pale. The aedeagus of a 

 dissected specimen from Kansas appears hke that of gentilis. This 

 darker coloring of the western specimens may be analogous to that of 

 western specimens of dorsalis, Say's atriventris. Horn gives a record 

 of P. gentilis being taken on Robinia pseudacacia by Dr. Hamilton.
