490 SOUTH AMERICAN HALTICIDAE (cOLEOPTERa) 



antennae reaching below the middle of the elytra, (eleventh joint missing) 

 black, three basal joints rufous, the rest much elongate and transversely 

 dilated, thorax the usual form for the genus, slightly depressed transversely 

 behind and longitudinally in front at the middle, the surface dull with fine 

 punctures and yellow pubescence; scutellum dark fuscous; elytra deeply 

 punctate striate, becoming obsolete at apex, very lightly depressed before the 

 middle, the depression being slightly deeper at the shoulders, thus bringing 

 out the scutellar area, the elytra seem to be lightly pubescent everywhere 

 except the spot at the apex and the linear effect above spoken of is somewhat 

 one of light and shade, and is shown best when the specimen is viewed squarely 

 from above; also, especiallj^ at the sides, are a few scattered hairs arranged 

 longitudinally; body below and legs yellow, claws bifid. 



The differently shaped antennae might throw this form into 

 some other place, but the shape of the thorax, etc., impels me to 

 keep it here; parvtdus Jac. has very transversely broad antennal 

 joints. 



Rhinotmetus bruchii nov. sp. 



Oblong, rather depressed, head, thorax, body beneath and legs 

 dull yellow, elytra ferruginous, with narrow antemedian and 

 postmedian transverse bands of dark pubescence and scattered 

 longitudinal markings of gray pubescence. 



Type. — Province of Buenos Aires, Argentine. (C. Bruch.) 

 Length 2.5 mm. 



Head not produced anteriorly, front and rear closely and finely jumctured and 

 with two small smooth tubercles, just back of the antennae, which latter are 

 short and stout, joints six to eleven thickened and transverse, thorax semi- 

 shining, with very fine punctures and minute pubescence, not as much nar- 

 rowed and depressed anteriorly as in many of the Brazilian forms, still enough 

 to bring it within the province of the genus, on each side back of the middle 

 is an oblique shallow depression; scutellum flavous pubescent, elytra strongly 

 punctate striate rather square across the shoulders and parallel sided, a faint 

 antemedian depression bringing out the scutellar region; of the two dark bands 

 the first is oblique forward, the second oblique backward tending to make a ^^ 

 spot, the paler pubescence is mostly within the dark area. Claws appendicu- 

 late. 



Seems to me near minutits Jac. by its antennae and claws. 



The species was in the second Jaco])y Coll. No. 28c and has 

 been sent to me by Dr. Bruch ; all the specimens I have seen have 

 originated with him.
