F. C. BOWDITCH 489 



in front, margined, slightly transversely depressed behind; bright yellow, 

 clothed with fulvous pubescence, scutellum fulvous; elytra punctate striate, 

 well marked near the shoulders, faint on the disk and obsolete at the rear, a 

 faint depression gives prominence to the scutellar region, in addition to the 

 yellowish pubescence, the surface is sparsely sprinkled with long upright hairs 

 in longitudinal lines; body beneath dark rufous, legs bright yellow with tibiae 

 and tarsi very dark rufous, claws bifid. 



Belongs near leptocephalus Perty. 

 Rhinotmetus marginatus nov. sp. 



Usual elongate form, head black, thorax yellow, elytra blue 

 black, shining, suture and apex narrowly margined with yellow 

 pubescence, legs yellowy tarsi and tibiae more or less rufous. 



Type. — Rio Janeiro, Brazil. Length 5 mm. 



Head produced in front, very sparsely pubescent, clypeus broadly foveate 

 on each side, with a median carina which ends between the antennae in a 

 frontal Y fovea, forming two smooth shghtly oblique tubercles which end 

 about the middle of the eye, back of that the surface is closely rugose striate 

 with a fine smooth median carina which nearly reaches the base, antennae 

 short, dark, rufous at base (missing after the seventh joint); thorax very 

 finely punctulate and sparsely flavous pubescent, anteriorly compressed and 

 depressed as usual in the genus, also transversely depressed behind, sides 

 margined, subparallel behind and (viewed from behind) showing a faint angu- 

 lation just below the middle; scutellum dark rufous; eh^ra, mth a faint 

 antemedian depression, which becomes well marked when it curves up to the 

 base by the shoulders, punctate striate, at base and sides, becoming obsolete 

 beliind, interspaces very minutely alutaceous, with long hairs sparsely arranged 

 in longitudinal lines, body beneath blue black, anterior tibiae and tarsi more 

 or less suffused with dark rufous, claws bifid. 



By its color it should be placed near sidcicoUis Clark, but none 

 of his species have the suture pubescent. 

 Rhinotmetus jacobyi nov. sp. 



Usual form, head blackish rufous, thorax yellow, finely pubes- 

 cent, elytra black, deeply punctate striate, with a faint stripe of 

 yellowish pubescence, from the humerus oblicjuely to the suture, 

 following that until it reaches the decUvity at the rear, thence 

 curving in a semicircle to the apex, having a common rounded 

 ante-apical bare spot, body below and feet yellow. 



Type. — Sta. Catharina, Brazil. Length 4 mm. 



Clypeus smooth, shiny, with a strong median carina, ending between the 

 eyes in a Y fovea which makes two smooth frontal tubercles, rear of the head 

 closely rugosely i)unctate, tricarinate, the median reaching the base and the 

 others parallel to the eyes; the clypeus and tubercles are noticeably rufous;
