“Form oval, head vellowish ochre, as long as wide between the eyes 
behind; interocular space with the lateral sides subparallel on the 
posterior half, progressively narrowed in front on the anterior half. Its 
width behind is equal to three times the transverse diameter of the eye 
on the same level. Surface of the head ver_ finely punctured, the punc- 
tuation a little less strong near the eyes. Vertex nearly smooth, finely 
rugulese, with the traditional spot of the genus a little broadened; very 
attenrated in front, “divided” at mid length, brownish, but very vaguely, 
poorly defined. 
“Pronotum a little longer than the head on the median line. The 
anterior angle almost right angles, a little acute. not acuminate. The 
lateral margins feebly arcuated, divergent tehind on their entire length; 
posterior lateral angles broadly rounded. Transverse furrow very pia‘n, 
sunken, quite strong on the margin, narrowly interrupted on the median 
line; the punctuation fine end dense on the whcle surface, a little more 
accentuated on the two anterior parts of the Jateral margin. The 
anterior margin, which appears finely bordered between the eves, is 
marked also behind the middle by fine transverse wrinkles that are 
rather crowded. The margin yellowish ochreous, rather broad; the disc 
and interior portion a little darkened, by the dets and small brownish 
blotches appearing poorly defined, the two median longitudinal ones a 
little more visitle, arcuated, converging in front and behind, but not con- 
fluent, allowing between them a pale median line, unspotted, narrowed in 
front. and behind, breadened a little teyond the midd'e. In front reach- 
ing the anterior narrow black border, and behind reaching the transverse 
furrow; the portion behind the furrow ver” pale yellowish, unspotted, 
finely and densely punctured. ‘Scraped off? on a narrow margin, the 
length of the posterior border cf the pronotum. 
“Scutellum yellowish brown, finely and densely punctured with the 
wrinkles very visib’e, little regular, and a little reticu’ated in places, 
especially toward the base. The principal wrinkle occupies the mid- 
length of the posterior half of the scutellum and is cut across a little 
before the summ't Fy another transverse wrinkle. 
“Elytra_ very finely and densely punctulate, granulate, of a yellowish 
brown, quite uniform, with the margin of embolium clearer yellowish. 
Commissure of the clavus a little longer than the middle of the length of 
the scutellum. Membrane brownish. a little darker then the elvtra. 
Connexivum yellowish brownish, a little darker on a narrow band cover- 
ing the sutures; posterior angles of the segments almost right angles, 
very feebly acuminate, and not prominent. 
“Labrum very small, transverse. subrounded in front. Rostrum hrown- 
ish, darker et extremity. Under the body a large part uniformly brown, 
legs yellow ish, the femora paler than the tibie; length, 7.2 mm.; width, 
4.5 mm.’ Taken in California, as the name would imply.

“Head and pronotum smooth; the latter with the sunken points scat- 
tered on the sides. Rather strong transverse wrinkles covering the 
slight depression at the middle of the anterior border of the pronotum. 
ye lowish ‘a dessins’ the Frown peints less marked on the head and pro- 
notum; the transverse furrow on the pronotum well marked, the color 
clearer on the smooth region behind the transverse furrow. The pro- 
notum very much widened behind, having the lateral margins very con- 
vergent for almost the’r entire length. Postero-lateral angle quite 
broadly subtruncate, a little rounded. Eyes also quite strongly con- 
vergent for almost their entire length. The length of the head is much
