name Proplectus decipiens (Rev. d'Ent., 1890, p. 197). Parabo- 

 licum Brentl., was doubtfully refei'red to Trimioplectus, but the an- 

 tennal and abdominal structure seems to prohibit this association. 



The coloration of clavicor^ne Makl. is very unusual in this genus, 

 all the other species being of a more or less pale testaceous. In 

 regard to impunctatum, if the desci'iption and figure of the maxil- 

 lary palpus published by I)r. Brendel are even substantially correct, 

 it must form the type of a very distinct genus. 



In drawing up the above table I have before me only the female 

 of politum, and am unable to see the base of the abdomen in mari- 

 nicum, the characters of these species being inferred from their 

 resemblance to californicum and candidum respectively. 



A. candidum n. sp. — Rather slender, moderately convex, polished, 

 rufo-testaceous, subimpnnctate ; pubescence short, sparse, recumbent. Head 

 rather large, with two small deep spongiose fovese midway of the length, 

 separated by one-half the total width, connected by an acutely parabolic 

 sulcus ; antennal tubercles somewhat prominent, crossed by a fine deep 

 sulcus ; eyes rather prominent, barely as long as the tempora, the latter 

 feebly convergent ; antennpe twice as long as the head ; under surface with 

 long sparse capitate setae. Prothorax slightly wider than long, widest at 

 apical third ; sides thence convergent and nearly straight to the base, the 

 latter one-half wider than the apex ; transverse sulcus deep, at basal third, 

 deeply prolonged backward in the middle ; fovea small but deep. Elytra about 

 as long as wide, two-thirds longer than the prothorax and nearly twice as 

 wide; sides arcuate; discal stria extending not quite to the middle, sntural 

 fine, deep, entire. Abdomen slightly shorter and narrower than the elytra, 

 gradually pointed behind. Legs short, the two anterior shorter and stouter. 

 Prosternum with two large spongiose antecoxal fovese ; intermediate coxae 

 contiguous, the cavities confluent ; corresponding trochanters toothed within 

 in the male. Length 1.2 nmi.; width 0.3 mm. 



California (Santa Cruz Co.). 



A single male, easily distinguishable among the Californian spe- 

 cies by the unusually large head, this being only just perceptibly 

 narrower than the prothorax. The male pygidium is perfectly flat, 

 evenly elliptical and very slightly wider than long. 



A. niarilliciini n. sp. — Moderately slender, strongly convex, polished, 

 subimpunctate, pale yellowish-ferruginous throughout ; pubescence short, 

 sparse and subrecumbent. Head rather small, distinctly shorter and nar- 

 rower than the prothorax, wider than long, rapidly and sinuately narrowed 

 before the eyes, the width at the prominent antennal tubercles not quite one- 

 half that across the eyes ; foveae small, deep, spongiose, in the middle, sepa- 

 rated by two-fifths the total width, connected by a broadly parabolic and
