Y nr. pectoralis iiiiy . — Entirely yellowish testaceous above and be- 
neath. Specimens often occur with a transverse fuscous fascia behind 
the middle of the elytra, which extends narrowly along the suture to 
the apex. 
This form occurs from Massachusetts to California and Texas. 
Va.r.futilis Lee. — This does not differ from the preceding variety, 
except in its smaller size and with apparently a slightly more rugose 
thoracic sculpture. A subvariety occurs in Arizona entirely piceous. 
'fhese latter are the smallest specimens seen (.06 inch). 
Occurs at San Diego and Owen’s Valley in California, and also in 
Arizona. 
Var. inops Lee. — Piceous, elyti’a with an indefinite humeral yellow 
spot, a short transverse band at middle adjacent to the lateral mar- 
gin, these two sometimes united along the margin, a subapical yellow 
space. Specimens often occur with a median discal space of the 
thorax yellowish. 
Occurs in California and Washington. 
Var. . — Entirely piceous, and occasionally with the 
legs darker than normal. 
This is known to me from the extreme northwest, Washington, 
although one from Iowa has merely slightly paler humeri. 
From the localities given this seems to be the most widely dis- 
tributed of our species.
