This species belongs, among those with six-jointed antennae, in the 
subgenus Cnemocyllus, the light forms belonging near canus and the 
dark forms near lzgatus. ‘The great variation displayed by individ- 
uals bred from the same material issues a warning against using 
color pattern in a table for separation of species. 
Length 1.5 to 2.2 mm. Elliptic, pitchy brown, very densely 
clothed with large scales, which on the elytra and thorax beneath 
are round, on the prothorax above a little longer, and on the abdo- 
men ovate. They are greatly condensed on the sides. The scales 
form a more or less distinct pattern; on the thorax the median line is 
heht with broad dark bands on each side of it, with hght lateral vittae, 
darger sublateral vittae, and a lighter underside; scutel ight; basal 
margin of elytra, basal quarter and apical half of first interspace, 
second and last quarters of third interspace, third eighth of fourth 
interspace, basal three-eighths of fifth’ interspace, third eighth of 
sixth interspace, last three interspaces and greater part of apex, 
light. Head with an impressed frontal line extending upon the base 
of the rostrum. Beak about three-fourths longer than prothorax. 
Prothorax over one-third wider than long, sides almost parallel in 
basal half, strongly narrowed and distinctly, though not suddenly, 
constricted at apex. LElytra wider at base than prothorax, slightly 
rounded on sides, subparallel, gradually rounded to apex behind; 
striae prominent, but punctures concealed by scales. Anterior femora 
armed with a sharp distinct tooth; posterior tibiae of male regularly 
curved. 
The colors are quite variable and may be given in combinations 
as found in the typical material: (1) Purplish red with lemon yel- 
low and brown; (2) dark brown and purple with creamy yellow; (3) 
greenish black and purple with creamy yellow and pink; (4) greenish 
black, purple and brown with creamy yellow and pink; (5) purple 
and brown with greenish white; (6) dark brown with light brown 
and creamy yellow; (7) lght brown and pale yellow; (8) pale

ANTHONOMUS (CNEMOCYLLUS) BACCHARIDIS, new species. 
Several specimens taken on Baccharis species in Madera Canyon, 
Santa Rita Mountains, Arizona, May 26, from the Hubbard and 
Schwarz collection. | 
This species belongs near aphanostephi, but differs by having the 
beak only about two-sevenths longer than the prothorax, the 
prothorax not more than one-third wider than long, and by the scales 
being less densely placed and condensed along the median line and on
