98 MEMOIRS ON THE COLEOPTERA 



length; disk more shining medially than laterally; elytra elongate, 

 oblong-oval, three-fifths longer than wide, less than one-half wider 

 than the prothorax, gradually ogival behind; striae rather fine, not 

 impressed, entire, the punctures fine, moderately close, traceable to 

 the declivity; foveae small, before basal and behind apical third. 

 Length (9 ) 5.0 mm.; width 1.65 mm. California (San Diego). 



extricatum n. sp. 



Form narrower, rather convex, black, with moderate alutaceous lustre, 

 the elytra piceous, with traces of paler markings of the same char- 

 acter as in the preceding, but much more retracted; inflexed sides 

 and legs testaceous-brown, the under surface black; head smaller, 

 nearly three-fourths as wide as the prothorax, with feeble sulci and 

 moderate eyes; antennae slender, of more uniform black than in the 

 preceding, the basal joint rufous beneath, the medial joints not dis- 

 tinctly more than twice as long as wide; prothorax shorter, fully 

 one-half wider than long, the sides strongly but more anteriorly 

 rounded, oblique in nearly basal half, becoming faintly sinuate only 

 at the angles; margins moderately reflexed; apex almost truncate; 

 surface with some wavy rugulosity, the impressions feeble; fovese 

 moderately deep, equal in length to the carina and less than a fourth 

 the total length; elytra oblong-oval, more than one-half longer than 

 wide, two-fifths wider than the prothorax, the striae entire, distinctly 

 impressed, fine apically, the punctures moderately separated, strong 

 and more conspicuous basally; foveae only slightly before basal and 

 behind apical third; third interval wider than the others. Length 

 (9) 4.0 mm.; width 1.3 mm. California (Tehatchapi Pass), 

 Wickham caudex n. sp. 



Form somewhat ventricose, less convex, much smaller in size, slightly 

 viridi-aeneous and dull anteriorly, the elytra piceous, each with a 

 basal spot, a short fascia at basal third, formed by spots on intervals 

 three to five, a wider but similarly formed fascia at apical third, 

 from the margin to interval five, and the apex, pale; under surface 

 and legs as in extricatum; head nearly four-fifths as wide as the pro- 

 thorax, with prominent eyes and broad, moderately deep sulci; an- 

 tennae slender, nearly as in caudex, the medial joints barely twice as 

 long as wide; prothorax short, one-half wider than long; sides mod- 

 erately rounded in apical, converging in basal, half, broadly but dis- 

 tinctly sinuate basally, rather strongly reflexed, the angles nearly 

 right, sharp; impressions feeble; foveae small, short, narrow and lin- 

 ear, the carina longer, rather strong, nearly a third the total length; 

 elytra oblong, less than one-half longer than wide, almost one-half 

 wider than the prothorax, broadly parabolic in apical third; striae 

 rather fine but strong, impressed suturally, the seventh a row of 

 fine punctures, becoming a distinct stria apically; punctures small 

 but deep and rather close-set; foveae near basal fourth and apical 

 third. Length (9) 3-6 mm.; width 1.25 mm. Arizona (near Ben- 

 son), Dunn pimanum n. sp.
