the femora all strongly clavate. Length 2.0 mm.; width 0.8 mm. 

 Alaska (Prince of Wales Island) and Queen Charlotte Islands. 

 The specimen described is a male, taken by Mr. H. F. Wickham. 

 Mr. Keen states that he has taken it at Massett, but I have not seen 

 any examples from that region. This and the next are by far the 

 largest and stoutest species of the four known to me. 



2. Li. arcifer n. sp. — Suboval, rather stout and ventricose, polished, im- 

 punctate, dark rufo-testaceous throughout, the legs and antennse but slightly 

 paler; pubescence moderately abundant, coarse, not very lojig, suberect and 

 strongly recurved, shorter and not conspicuous on the prothorax, denser and 

 coarse at the sides, very sparse and inconspicuous on the head except toward 

 base, where there are many long erect and conspicuous hairs and slender 

 spinules bristling over the nuchal excavations. Head with the neck a little 

 longer than wide, the surface convex anteriorly but gradually declivous to the 

 neck, which is deeply excavated transversely, the hollow bisected by a fine 

 longitudinal carina of moderate elevation; clypeus moderate in length, 

 broadly rounded, the surface subconical; eyes not very large, at the middle 

 of the sides, convex and prominent. Antennee distinctly longer than the head 

 and prothorax, stout, gradually enlarged distally; basal joint cylindric, as 

 long as the next two and thicker, scarcely }4 longer than wide; second feebly 

 obconic, scarcely ,^4 longer than wide; third equally wide but very short, sub- 

 lenticiilar, twice as wide as long; four to six enlarged and closely connected, 

 the three having within a common deeply hollowed excavation, which is even 

 and extremely finely, densely rugulose and pubescent, the hairs very short; 

 seven to eleven normal, gradually and slowly increasing in thickness; seventh 

 about % as wide as the sixth; seven to ten almost perfectly similar in form, 

 obtrapezoidal, slightly wider than long; eleventh as long as the two preceding, 

 gradually and obliquely pointed. Prothorax slightly longer than wide, % 

 wider than the head; sides carinate and parallel in about basal half, feebly 

 convergent and slightly arcuate thence to the apex, which is truncate and 

 nearly % as wide as the base; disk transversely impressed near the basal 

 margin, the impression very finely and abruptly interrupted at the middle, 

 and also with a deep, slightly elongate-oval fovea at each side near the carina 

 and not connected with the transverse impression. Scutellum small, elongate- 

 oval, flat. Elytra % longer than wide, 2^5 times as long as the prothorax and 

 twice as wide, oval, widest near basal % but with the sides broadly and very 

 evenly arcuate, gradually parabolic behind ; humeri obliquely and more strongly 

 rounded; humeral plica long, oblique, acute, the subhumeral impression long, 

 narrow, deep and oblique; basal fovea distinct, its impression large, oval; 

 subsutural impressions subobsolete, the suture very faintly beaded toward base ; 

 the bead becoming lost at the apex of the scutellum. Legs well developed, the 

 four anterior femora rather strongly clavate, the posterior evidently less 

 strongly; tibiae gradually very narrow toward base; tarsi slender. Length 1.9 

 mm. ; width 0.7 mm.
