seems best to leave the generic determination to a future monograph 

 ot this group, and we prefer to leave the species in that genus under 

 which it was originally described. lu order to facilitate the recognition 

 of this species, which has been described in publications not readily 

 accessible, we append a description ot* the imago by Mr. Schwarz which 

 he has drawn up at our request to accompany these notes. 



Generic characters. — Rostrum slender, moderately curved beneath, in the male with 

 impressed median line and two longitudinal rows of rounded tubercles. Anteunse 

 sub-basal, funicle 6-jointed, first joint longer than wide, second longer thau the first, 

 the following sub-transverse gradually becoming larger; club hardly securiform and 

 moderately^ compressed, spongy portion nearly two-thirds as long as smooth portion 

 and obliquely truncate each side. Eyes transverse, flat, not contiguous beneath. 

 Prosternum between coxae- not linear and about half as wide as the diameter of the 

 coxal cavity. Scutellum elongate, flat. Mesothoracic epimeranot ascending, obtuse 

 at outer anterior angle. Legs rather stout, femora thickening apically and strongly 

 sinuate at tip; tibise not curved, longitudinally carinate, on inner side fringed with 

 very short setse; third tarsal joint large, entirely spongy pubescent beneath, second 

 and third joints spongy pubescent at tip. Abdomen with 5 segments. Closely allied 

 to CactopTiagiis, with which it agrees in the form of the antennal club and the third 

 tarsal joint but differs in the shorter beak, which is bi-seriately tubercled beneath in 

 the (J; second joint of funicle longer than first; scutellum elongate, legs stouter with 

 clavate femora, tibiae longitudinally carinate. 



Specific characters of S • — Length from tip of thorax to tip of elytra 13. .5 millimeters. 

 General color rufo-piceous (perhaps immature). Beak as long as thorax, but little 

 compressed, gently dilated at basal third; above rather finely and densely punctate, 

 more coarsely at the sides ; a small frontal puncture ; beneath the impressed median 

 line becomes deeper and wider toward the base, the tubercles forming the row each 

 side of the median line smooth and rounded and more numerous at tip than posteriorly. 

 (Fig. 43, &). Head sparingly and finely unctate. Antennal scape opaque and 

 tomentose, first and second joints of funicle smooth except at tips, the remaining 

 joints opaque, nearly moniliform ; smooth part of club with a row of coarse setigerous 

 punctures near the base. Thorax distinctly longer than wide, basal margin rounded, 

 sides straight from base to beyond the middle, thence arcuately narrowing; a well- 

 marked, short tubular constriction at tip, front margin straight; surface shining, 

 even, except a slight ante-basal median depression ; rather finely punctulate on disc, 

 with an ill-defined longitudinal smooth space at middle, punctures larger toward the 

 sides and especially in the ante-basal depression, basal margin densely punctured ; 

 color orange-yellow with rather broad black median stripe not reaching apex and 

 base; flanks more opaque with two large black patches. Scutellum elongate, acute 

 at tip, surface even. Elytra sub-opaque at base, as w4de as base of thorax, nearly 1^ 

 times as long as thorax and twice as long as wide ; humeri obliquely truncate, sides 

 feebly converging posteriorly, separately rounded at tip ; sub-oj)aque ; color (imma- 

 ture specimen?) dirty piceous-yellow with indistinct black marking (especially a 

 large longitudinal stripe toward the sides) ; puuctate-striate, striae moderately deep, 

 the punctures remote and not strong; suture at base with a row of fine punctures, 

 rest of suture and the other interstices each with a series of small tubercles 

 which are sometimes rounded but more often (especially posteriorly) confluent 

 into little longitudinal carinae of varying length. Pygidium sub-triangular, longer 

 than wide, sub-truncate at tip, longitudinally convex, sub-opaque, deuselj'- punctu- 

 late at base, very coarsely and more sparsely at apex. Underside reddish piceous, 

 somewhat shining; pro- and mesosteruum coarsely punctured, the former without 

 impression (except the apical constriction), the latter with moderately deep notch at 

 middle, opaque and si^arsely punctured at sides ; first abdominal segment as long as
