Horn.] 568 [April 19, 
opaque, densely and rather finely granular, prothorax beneath coarsely 
granular. Length .30 inch; 7.5 mm. 
This species reproduces in miniature the appearance of 
Phellopsis obcordata. 
One specimen given me by Mr. Jas. Behrens, collected at 
Mount Shasta, California. 
PHL@ONEMUS Erichs. 
Antenne eleven-jointed, last two forming an abrupt club, which is 
glabrous. Head broad, clypeus broadly rounded in front, sides dilated, 
and extending to the middle of the eyes, beneath with deep, slightly ob- 
lique antennal grooves. Eyes coarsely granulated, moderately convex. 
Mentum transversely quadrate, maxillary palpi with terminal joint cylind- 
rical-compressed, longer than the preceding together and truncate at tip. 
Labrum retracted. Abdominal segments gradually decreasing in length, 
their posterior margins straight. Intercoxal process narrower in front and 
rounded at tip. Anterior tibive slightly dilated at tip, the outer margin not 
fimbriate. Tibize with distinct terminal spurs. Tarsi rather short, first 
three joints short and nearly equal, together shorter than the fourth, 
sparsely hairy beneath. Form oblong-elongate moderately convex. 
Ph. catenulatus, n. sp. 
Oblong-elongate, reddish-brown, base, apex and suture of elytra some- 
what paler. Head granulate, sub-opaque. Thorax one-half broader than 
long, apex emarginate, angles obtusely prominent in front, sides feebly ar- 
cuate in front, then straight and nearly parallel, margin slightly explanate, 
obsoletely crenulate, base feebly arcuate, hind angles rectangular, disc 
moderately convex, moderately densely granulate, surface with feeble ele- 
vated anastomosing lines. Elytra oblong, parallel, base not wider than the 
thorax, humeri obtuse, a sub-sutural and four discal cost, and lateral 
margin acutely prominent, intervals biseriately catenulate. Body beneath 
paler than above, rugulose. Length .18 inch; 4.5 mm. 
One specimen, collected by myselfat Fort Yuma, California. 
This genus was indicated by Erichson in a few words 
without describing the typical species. The antennee have 
the first two joints stouter, the second shorter than the first; 
third joint slightly longer than the fourth; 4-9 very 
gradually increasing in length and width; 10 abruptly 
broader emarginate at tip, 11 transversely oval, narrower 
than the tenth and pubescent at tip. 
COXELUS Latr. 
Antenme eleven-jointed, last two joints forming a sudden club. Eyes 
free. Head with antennal grooves beneath the eyes. Tibi slender with- 
out terminal spurs. Our Species are winged.
