Psyche 
[Sept. 
Head subtriangular, without occipital callosities or 
deeply impressed hind margin. Surface shiny, feebly 
microreticulate, moderately densely and deeply punctured 
except near the midline on the occiput, on the antennal 
calluses and on a narrow zone behind the eyes. Midline 
distinctly impressed to just below the upper level of the 
eyes. A narrow zone in the middle of the head often gla- 
brous and without punctures, as in Fig. 2A. Antennal 
calluses small but denuded. Eyes oblique, narrow, 
rounded at the inner margin, bordered behind by a nar- 
row, smooth, denuded zone one-fourth their greatest 
width. There is no trace of a pit at the inner edge of this 
denuded zone. Clypeus and labrum sculptured like rest 
of head. Antennae almost uniform in thickness, reaching 
the basal third of the elytra, two and one-half times as 
long as an anterior tibia. First segment reaching one- 
third across the eye, moderately slender but nevertheless 
the thickest segment. There is often some cinereous pu- 
bescence on the dorsal and posterior surfaces. Second 
segment two-sevenths as long as first, moderately slen- 
der ; third slender, a little more than twice as long as sec- 
ond; fourth three-fourths as long as third; the rest de- 
creasing slightly in length and thickness. 
Pronotum slightly broader than long, with the sides 
roughly parallel on the basal two-thirds, then converging 
at a forty-five degree angle. Surface more deeply punc- 
tured and microreticulate than that of head. Disc 
roughened, flattened on the basal two-thirds, with a feeble 
narrow median smooth area on the basal half. Basal 
impressed line deep ; median suture absent or present only 
on the middle of the disc. Pubescence of the disc sparse, 
directed laterally in part and in a pair of small anterior 
whorls. Elytra with slightly denser pubescence than the 
head, with scutellar and humeral black spot, inconspicuous 
because of the sparseness of the pubescence. Pubescence 
of the underside denser than above, uniformly pale ciner- 
eous. Second to sixth abdominal sternites of male 
broadly denuded, the sixth strongly notched apically. 
Legs with pale cinereous pubescence except for the tips 
of the femora, tips of the tibiae and outer edge of mid-
