Psammodius grundeli n. sp—Oblong, slightly broader behind, convex, 
moderately shining, piceous, legs rufous, antennz rufo-testaceous. Head 
moderately convex, coarsely and moderately closely verrucose, a distinctly 
defined linear transverse impression separating verrucose area from occi- 
put, the occiput smooth except for a few minute punctures near anterior 
margin; clypeus broadly and shallowly emarginate, angles each side obtuse 
and rounded, sides slightly arcuate, gene obtuse. Thorax one third wider 
than long, slightly narrower in front, anterior angles very obtuse and 
rounded, hind angles broadly rounded, base arcuate, the marginal line dis- 
tinct, disc convex, with median depression extending from base to middle, 
with coarse and somewhat widely separated punctures and-a few very 
minute punctures on intervening areas, with deep lateral transverse im- 
pression just back of anterior margin and another less defined half way 
to base, this latter extending vaguely on to the disc. Elytra as wide at 
base as the prothorax, humeri obtuse, sides nearly straight, slightly diver- 
gent, strie deep, moderately closely crenately punctured, intervals convex, 
smooth. Beneath slightly scabrous at sides of mesothorax and with abdo- 
men quite smooth. Posterior femora stout, smooth, the marginal line 
moderately deep, almost reaching trochanter; the tibia moderately stout, 
without oblique ridges, the spurs unequal, slender; the tarsi longer than - 
one half the tibia, the first joint somewhat broader at apex. Length 3.25 
mm., breadth 1.25 mm. 
Type in my own collection. Paratypes deposited in the U. S. National 
Museum and California Academy of Sciences. 
Twelve specimens in my collection served as a basis for this description. 
They were all collected at Martinez, Cal., in June, 1910, by Mr. J. G. Grun- 
del, after whom I take pleasure in naming it. Other specimens in the col- 
lection of Dr. F. E. Blaisdell, also from the neighborhood of Martinez, 
have been seen. 
This species is perhaps most closely related to P. nanus De- 
Geer. It is, however, not only larger, but more elongate, with 
the longitudinal and transverse impressions better defined, and 
the punctuation of the elytra coarser. 
Psammodius desertus n. sp—Oblong oval, broader behind, convex, shin- 
ing, rufo-piceous, disc of thorax and occipital ridge piceous, elytra and 
femora testaceous. Head coarsely, irregularly punctured in front, finely 
and sparsely on occiput, with distinct yet slightly elevated transverse ridge 
in front of occiput, and vague short secondary transverse elevation be- 
tween this and clypeal margin; clypeus broadly emarginate, a small, obtuse 
reflexed tooth on each side, the sides slightly arcuate, a slight sinuation 
at end of frontal suture; gene feebly prominent, obtuse. Thorax one 
third wider than long, base broadly rounded, sides slightly arcuate and 
convergent forwards, fimbriated, no posterior angles, anterior angles 
obtuse, basal marginal line distinct, disc convex, moderately coarsely and
