Judging from Lacordaire's description, this genus seems to be 

 near Phceniton Schonh., but the form of the antennal joints is differ- 

 ent, the other differences are slight and may be variable in the spe- 

 cies of the latter genus. 



Gribiiriosoiiia platannm n. sp.— Black, thorax red, tibiae and apex 

 of first joint of tarsi pale. Head ratlier densely covered with greyish white 

 hairs. Antennae black. Sides of thorax gradually narrowing to apex, sparsely 

 clothed with white hairs, surface longitudinally, rugosely sculptured, red, apex 

 blackish. Elytra striate, strife closely punctate, black, clothed at base, sides and 

 declivous apex with short sparse white hairs. Underside and pygidium more 

 densely pubescent with longer white hairs. Length 6 mm. 



Huachuca Mts., Arizona. 



[ obtained this species from dead branches of a sycamore. It re- 

 sembles at first sight in form, color and markings Griburivs monte- 

 zumce. There is also an indistinct, obscure, reddish spot on each 

 side of elytra ; the subbasal and inferior carina of the thorax are 

 black, except the continuation of the subbasal carina at sides from 

 a little above the hind angles, where it has the color of thorax. 



Ph«eiiicobius SChwarzii n. sp.—ilMe.— Elongate, upper surface nearly 

 uniformly clothed with ochreous hairs. Head feebly convex, eyes feebly eraargin- 

 ate, clypeus at sides near antennal insertion feebly elevated ; antennae twice as 

 long as the body, formed as in chamseropis. Thorax at base longer than broad, 

 basal carina feebly lobed at middle, recurved along the sides to about middle, 

 hind angles rounded, sides near the latter slightly sinuate, disk on each side of 

 median line impressed ; on each side, outside of these impressions, a not very 

 strong tuberculiform elevation. Elytra more than twice as long as the thorax, 

 striae not impressed, but consisting of rows of moderately large punctures. Body 

 beneath rather densely clothed with paler hairs; legs annulated, tarsi shorter 

 than the tibiae, formed as in chamxropis, claws cleft, the inner portion smaller 

 than the outer. Length 9.25 mm. 



Female. — Antennae shorter than the body, beak at sides not elevated above the 

 antennal fossae, which are smaller than those of the male; otherwise as in the 

 male. Length 8 mm.

I take pleasure in dedicating this species to Mr. E. A. Schwarz. 

 It is readily distinguished from ehamceropis by its nearly uniform 

 coloration, denser pubescence and more robust form, There are a 

 few irregularly placed, apparently darker spots on elytra, caused by 

 the pubescence being there yellowish grey and finer and sparser, 

 permitting the surface color of the elytra to be seen ; near tlie side 

 margins of elytra are a few spots of darker hairs, the liead has a
