as long as the basal joint of antennse ; auteunse black, stout, subcylin- 

 (Irical, the joints all of nearly equal thickness ; first joint very short, 

 the second very long, almost equal to the third and fourth united, the 

 third orange on the apical half and longer than the fourth ; surface in 

 front of each eye raised into a blunt tooth ; rostrum rust-brown, fuscous 

 at tip. Pronotum transverse-subreniform, the anterior margin widest, 

 arcuated, and broadly recurved each side, the margin irregularly and 

 minutely toothed, the anterior angles a little acutely promiuent ; lateral 

 obliquely narrowing posteriorly ; posterior angles forming broad, rounded 

 lobes, the posterior margin deeply sinuated; surface deeply depressed 

 each side, irregularly and coarsely granulated, the disk with two longi- 

 tudinal, approximate, raised lines, each side of which is a subiuterrupted, 

 less distinct, raised line. Scutellum coarsely and irregularly granulated, 

 tumidly elevated on the disk, sunken behind the disk, and, with the lat- 

 eral margins very prominently elevated. Legs black; the coxse, base of 

 femora and a ring before their tip, the tip of tibine, and the tarsi ochre- 

 ous yellow. Hemelytra deep black, more finely granulated, extending 

 almost to the tip of the abdomen ; base of corium exteriorly expanded 

 into a wide, oval flap, which is broadly recurved, and the edge minutely 

 serrated. Venter a little ferruginous ; the central carina paler ; the outer 

 angles of the segments and a small part of the edges of the incisures of 

 the connexivum both above and below ocher-yellow. 



Length, 11 millimeters. Width of pronotum, 4 millimeters. 



Inhabits California (James Behrens).

Long, narrowingposteriorly, pale rust-brown 5 form similar to^. acutus, 

 Say. Head long, longer than the width across the eyes, minutely and 

 densely granulated; the protuberance entire, cylindrical, thick; cranium 

 with a few coarse granuleson the central ridge; processes of the antennal 

 base short, acute; surface adjoining the eyes infuscated; before the eyes 

 is a blunt, vertical process ; antennai very slender, the joints cylindrical, 

 densely and evenly gra,nulated, the second joint longer than the head, 

 third and fourth joints a little stouter, the third whitish except at base, 

 the fourth fuscous, a little shorter than the third, conical at tip; rostrum 

 chestnut-brown, minutely, evenly granulated, reaching to the incisure 

 between the meso-and meta-sternum. Pronotum wide sublunate, almost 

 twice as wide as its length ; the antero-lateral arcuated margin irreg- 

 ularly and remotely denticulated, broadly recurved, infuscated; posterior 

 margin widely sinuated; behind the humeri produced into rounded 

 flaps; disk infuscated, crossed by four longitudinal, anteriorly approxi- 

 mating, subentire, carinate lines; callosities very prominent, and bounded 

 by sharply-defined lines. Scutellum infuscated, the basal angles tu- 

 midly elevated, the sides bounded from the base to beyond the middle 

 by prominent, thick, carinate edges, the disk triangularly tumid, and 

 sending backward a carinate longitudinal line. Legs irregularly gran- 

 ulated, faintly marbled with fuscous; the tips of tibise and a faint band 

 on their middle yellow. Hemelytra clouded and marbled with fuscous ; 

 the base of tbe corium somewhat expanded into rounded, upturned lobes; 

 membrane slightly net-veined, marbled, and clouded with fuscous. Ven- 

 ter almost uniform pale ferruginous; tergum a little darker ; the con- 

 nexivum faintly clouded with fuscous, and with a fuscous spot at the base 

 of the segments adjoining the incisures. $
