Microedus austinianus sp. nov. 



Black, shining, thinly clothed with fine, short pubescence, protho- 

 rax wider than long, sides and anterior angles rounded, posterior 

 angles obtuse 3 disc broadly convex, alutaceous, sparsely and obsoletely 

 punctulate, sides narrowly flattened towards the base, which is straight; 

 elytra a little wider than the pro thorax, three-fifths as long as the 

 abdomen, outer angle rounded, sutural rectangular; rather depressed, 

 finely punctured, with a large, ill-defined, dark brown spot extending 

 from the base to the middle; exposed part of abdomen obsoletely 

 punctulate, alutaceous, sides flattened. Length, 3.6 mm.; .14 inch. 



Several specimens collected in the White Mountains, by Mr. Aus- 

 tin; it also occurs in Vancouver Island. The antennas are about one- 

 half the length of the body, slightly thickened externally; third joint 

 a little longer than the second, which is equal to the fourth; sixth to 

 the tenth subtriangular, a little longer than their width; eleventh one- 

 half longer, oval, rounded at tip. Under surface finely punctured, legs 

 brown. 



I have established this new genus upon an insect resembling in 

 form Coryphium angusticolle of Europe, as figured by Duval (Gen. 

 Col. Europ. ii, pi. 24, fig. 120), but differing from that, as from the 

 other genera of Omalini having subulate maxillary palpi, by the 

 penultimate joint less swollen, being more than one-half longer than 

 its thickness at the distal end, and by the last joint slender, and acic- 

 cular, being only a little shorter ; the mandibles are acute and curved 

 at tip, armed with a sharp tooth beyond the middle. The head is 

 much swelled beneath on each side, and the space between the gular 

 sutures is very narrow. 



EpurgBa flavomaculata M'aklin, Bull. Mosc, 1853, p. 205. 



A remarkable species, which has been heretofore found only in 

 Alaska. It is easily recognized by the body being black above, with 

 the side margin of the prothorax and elytra yellow ; the latter each 

 marked with two yellow spots near the suture, one behind the base, 

 the other, smaller, behind the middle. 



Telephorus oriflavus sp. nov. 



Black, finely, scarcely perceptibly pubescent with short gray hairs; 

 head in front of the eyes shining yellow, behind dull black, finely 

 alutaceous; prothorax yellow, shining, with a broad black dorsal 

 vitta, one-half wider than long; anterior margin rounded; basal mar- 

 gin slightly rounded, narrowly reflexed, sides nearly straight, nar- 

 rowly reflexed; angles rounded, disc moderately convex; elytra not
