dispersed in our territory. I have seen specimens from Massachu- 

 setts, Virginia, South Carolina, Michigan, Illinois, Arizona, Oregon 

 and California. 



According to Belon the males have the frontal tibia? curved, but 

 in the twenty-five examples at hand I do not detect any difference 

 that seems worthy of mention. 



C. niistralicus Belon. — Very similar to constriclus in form, color and 

 sculpture, l»ut a little larger and differing constantly in the following respects: 

 The antennal club is 3-jointed ; the outer joints of the funicle are all distinctly 

 elongate; the tempora are scarcely more than half the length of the eyes; and 

 the elytral eosUe are more strongly elevated. (PI. Ill, figs. 14 and 14«). Length 

 1.65-2 nini. 



Hub. — California (Alameda ; Sylvania; Los Gatos ; Pomona). 

 For the identification of this species I am indebted to Mr. Belon, 

 who has carefully compared a Californian specimen with his Austra- 

 lian types, and finds no appreciable difference. It is not uncommon 

 in California. 



C nodi IV r Westw. — Moderately elongate, varying in color from testaceous 

 to piceous, glabrous, shining. Head, prothorax and under surface sculptured 

 much as in const ri etus ; eyes small, tempore as long as, or a little longer, than the 

 eyes and evidently convergent; antenna? slender, the .eighth joint nearly twice 

 as long as wide, the club 3-jointed. Elytra elongate-oval, intervals 3-5-7 costate, 

 the third undulate by reason of a subbasal and median discal impression, and 

 elevated into a prominent tubercle at about the apical third ; fifth interval more 

 strongly and acutely costate, most prominent near the apex ; seventh undulate. 

 Length l.H-2.1 mm. 



lI'iJi. — Washington (Tenino); Oregon (Hood River, Astoria); 

 California (Alameda, Los Gatos); Virginia (Ft. Monroe). 



This species, unlike constrictus and australicus, exhibits well de- 

 fined and unique secondary male characters. The hind tibia? in this 

 sex are rather strongly widened toward the apex and abruptly 

 angularly emarginate on the inner side immediately before the tip ; 

 there are also at the posterior margin of the metasternum two 

 prominent, conical, subacute tubercles, which are directed obliquely 

 backward. I have seen no mention of this latter character by 

 European authors. 



ENICMUS Thorn. 



This genus was established by Thomson for those species of 

 Lathridius, which, with normally large eyes, lack the discal costse 

 of the pronotum. The later European authors, while recognizing
