each puncture. Elytra elongate oval, a little wider than the prothorax; 

 strise punctured, becoming obsolete behind; interspaces each with a row of 

 well-marked distant punctures, from which proceed fine hairs. Beneath 

 finely and very sparsely punctured. Length, 2.5 mm. ; .10 inch. 



San Diego, on the shore of the bay, under sea- weed. <$ with the first 

 and second ventral segments broadly concave ; anal segments large, prom- 

 inent. 



Tribe VI. TBACHOINI. 



The genus Trachodes, which occurs in Europe, Asia and Alaska, differs 

 sufficiently from all others in our fauna to merit being placed in a separate 

 tribe. Lacordaire classed it with the Molytini, which however seems an 

 unnatural grouping of genera agreeing only in convex body, short meta- 

 sternum, and absence of wings. The beak is rather slender, as long as the 

 prothorax; the antennae are inserted a little before the middle ( 9 ), or one- 

 third from the end (cP), rather slender, the scape reaching the inferior 

 margin of the eyes, which are nearly round, coarsely granulated, and 

 somewhat removed from the prothorax; thefuniculusis.7-jointed, first joint 

 elongate and stout, second nearly as long, but slender, 3-7 short, slightly 

 increasing in thickness ; club rounded oval, about one-half longer than 

 thick, annulated, pubescent, tip rather pointed. Prothorax scarcely lobed, 

 but ciliate behind the eyes. Epimera of metathorax narrow, entirely cov- 

 ered by the elytra; hind coxae rounded, widely separated, not attaining the 

 elytral margin. Ventral segments, first and second large, each as long as 

 the metasternum, separated by a straight suture which is deeply impressed 

 at the sides; third and fourth short, sutures straight; fifth as long as the two 

 preceding united. Legs rather long, thighs pedunculated, not toothed ; tibice 

 slender, strongly hooked at tip; tarsi rather long, third joint wider, bilobed, 

 last joint elongate, claws simple, slender, separate. Body rough with short 

 erect bristles.

 from Col. Motschulsky as his T. fasciculatus, Bull. Mosc. 1845, 2nd, 374.

Alaska. The four tubercles of the elytra seem to me not elevations but 

 bunches of bristles; they are situated on the third interspace; the first is 

 about one-fifth from the base, and the second a little behind the middle; the 

 elytral striae are rather finer than in the preceding.
