488 SOUTH AMERICAN HALTICIDAE (cOLEOPTERA) 



The types of all the forms herein described are in my collection. 



Rhinotmetus similis nov. sj). 



Usual elongate form; head, thorax and feet more or less rufous, 

 elytra blue black, with fine punctures arranged as striae, flavous 

 pubescent, a basal and submedian spot on each elytron denuded 

 and shining. 



Type. — Merida, Venezuela (No. 398 green label). Second Jac. 

 coll. Length 5.5 mm. 



Head with a longitudinal carina extending from the middle of the clypeus 

 up between the antennae, ending just above their insertion in a fine cross 

 groove, above which is a pair of longitudinal frontal tubercles, and then a fine 

 carina extending as far as the rear margin of the head, the rear part of which 

 is granulate, strigose, suffused with black; antennae filiform, extending to the 

 middle of elytra, black, the first four joints and the apical one sufTused rufous, 

 thorax in the usual form of this genus, much narrowed, rounded and depressed 

 in front; also obsoletely, longitudinally channeled, very obsoletely punctulate 

 behind at the angles and sparsely flavous pubescent; rufous, suffused down 

 the middle with blackish; scutellum fuscous rufous, elytral punctures, well 

 defined at base, entirely obsolete behind, an antemedian depression which is 

 obsolete at the suture but well marked where it curls up by the shoulder, gives 

 the appearance of a raised callous to the scutellar area; in the specimen before 

 me the rear denuded spot attains the margin, but it is probable that in fresh, 

 ])erfect examples the pubescence covers the lateral edge, feet rufous with 

 tibiae and tarsi more or less black, claws bifid. 



This species belongs near leptocephalus Perty, but is much 

 smaller. 



Rhinotmetus trifasciata nov. sp. 



Usual elongate form, head, thorax and feet more or less bright 

 flavous yellow, elytra shining blue black with three transverse 

 bands of flavous pubescence, ante and post median and apical, 

 the former with a branch encircling the shoulder and all attain- 

 ing the margin, the suture also narrowly pubescent. 



Type.— Cachabe, Ecuador; low c, I, 1897, (Rosenberg). Length 

 6 mm. 



Head sparsely flavous pubescent, more thickly round the eyes, anteriorly 

 flavous, becoming dark rufous towards the rear, clypeus wide, shining, tricari- 

 nate, broadly foveate on either side, the median carina continuing between 

 the antennae, when it parts into a Y frontal fovea, forming two smooth oblique 

 tubercles, rear portion of the head rough, strigose with fine punctures and finely 

 carinate nearly to the base, antennae black, filiform, short, reaching only 

 slightly below the elytral base; thorax shaped as usual in this genus, rounded
