1911] Hypera and Phytonomus in America 417 



funiclc, first funicle joint nearly twice as long as second, second longer 

 than third, seventh joint broader and shorter than the others, last joint 

 of club more elongate, longer than others, all covered with fine pube- 

 scence ; antennas inserted about one-third back from tip of beak. 



Prothorax slightly longer than wide, widest in the middle, anterior 

 and posterior margins of almost the same width, sides rounded and im- 

 pressed posteriorly, a dfiep impressed groove near the anterior sternal 

 margin which extends upwards on the sides gradually becoming indis- 

 tinct ; anterior margin below with a fringe of hair projecting forward i >ver 

 the suture; punctures rather coarse and dense in each puncture lies a 

 small narrow truncate or rounded scale. 



Seidell ii in small triangular, elongate and usually covered with finer 

 paler scales. 



Elytra elongate-oval, narrow in front, sloping gradually outward for 

 three-quarters of length and then quickly narrowed, from the side only 

 slightly declivous behind; stria:' distinct, punctured, interspaces scarcely 

 elevated, scales arranged irregularly on interspaces as compared with 

 quadricottis, but much more regular than in other species, often over- 

 lapping, but never lying across the stria;; no seta in the si rial punctures. 



Venter covered with fine generally paler scales, abdomen flatter in 

 male than in female and with a faint indication of an impression on the 

 first segment ; mesosternal process between the middle coxa' elevated for 

 half its length and broadly triangular, then curved backward contracted 

 and again enlarged near the truncate point; the process of the metaster- 

 num appears to fit into a socket on the under side of the mesosternal 

 process; intercoxal process of third segment of abdomen not as wide as 

 coxa, projected further forward than usual. Male genitalia (Plate I, 

 figs, o-ti) with stem having elongate parallel sides for two-thirds of the 

 length then curved smoothly in to the rounded point. 



Legs with all the coxas, and femora in front clothed with narrow 

 scales, tibia? and tarsi with hairs which are sparsely set almost in rows 

 and sometimes short and stout; crown of spines on hind tibia short and 

 stout, spur of hind tibia very short, stout and red; tarsi above and claws 

 usually darker than remainder of legs; pad on the third joints long and 

 pale. 



The color of the adult beetle varies extremely; from a large number 

 of specimens bred by Dr. J. B. Smith, at Trenton, N. J., I have found 

 almost all the varieties sent from various localities over the United 

 States. The prevailing color seems to be rust-red, which is evidently 

 the color of the specimens described by Gyllenhal as diversus. Other 

 specimens are brown, gray, grayish-green, metallic-red, gray or gray- 

 green; others tesselated over the entire elytral surface with brown and 

 black maculae on a background of red or brownish yellow scales; a lew 

 are metallic greenish-black. The specimens sent Schoenherr by Say are 

 evidently small males of the obsoletely tesselated reddish forms. The 

 relation with P. rumicis is only superficial and extends neither to the 

 thoracic form, elytral markings, scale shape or genital structure. The 

 metallic vitta mentioned by Say as occurring on the prothorax appears
