494 SOUTH AMERICAN HALTICIDAE (cOLEOPTERa) 



two small acute teeth, one being on the trochanter joint, the 

 other alongside on the base of the femora, middle of hind tibiae 

 below with a long acute backward curved, spinous process. 



Type. — Cachabe, Ecuador; low c, XII, 1896, (Rosenberg). 

 Length 3.5 mm. 



Head vertical, with well markod frontal tubercles and a wide fovea, the 

 vertex with an obsolete smooth longitudinal carina; antennae reach below the 

 middle of the elytra; thorax elongate, quadrate, slightly constricted at rear, 

 with transverse, and oblique, side basal depressions, the latter well marked, 

 also a medium longitudinal fovea in front which in connection with the oblique 

 depressions brings out two well marked median calli; scutellum fulvous; elj'tra 

 with striae obsolete at tip, the lateral margin sharp and well defined, no visible 

 basal depression though the scutellar callous is obsoletely raised; the curvature 

 of the anterior femora is very strong at the basal half, the hind tibial spur is 

 sharply pointed, broad and stout at base and abruptly curved backward. 



The structure of the legs might easily put this species in a new 

 genus, but both sexes ought to be in hand before it is done. 

 One example. 



Phylacticus ephippium nov. sp. 



Elongate, fulvous yellow, thorax with sides broadly black, 

 elytra punctate striate, obsoletely so at apex, finely pubescent, 

 a sub-basal and sub-median band, black, connected together at 

 the suture and sides, leaving a fulvous crescent shaped spot on 

 each elytron at the middle. 



Type. — Cachabe, Ecuador; low c, XII, 1896, (Rosenberg). 

 Length 6 mm. 



Clypeus smooth, shining, front with T carina showing four broad flattened 

 tubercles and an obsolete ridge above, on either side parallel with the eye, rest 

 of surface thickly punctate; antennae filiform, fulvous, (eleventh joint missing) 

 thorax quadrate, sides margined, very shghtly sinuate, all angles prominent, 

 surface almost equate, punctate, sparsely pubescent, faintly depressed behind, 

 both transversely and longitudinally; elytra with shoulders not prominent, 

 declivous and narrowed behind, a faint anti-median depression a little more 

 marked where it curls up to the shoulder, the black subbasal band is drawn 

 back from the scutel, having a triangular shaped yellow area which includes 

 the scutellum and the black is pushed forward and almost attains the base, 

 where it meets the black edge of the thorax. The whole surface is finely 

 pubescent which gives it a dull look, body beneath and legs yellow, claws 

 appendiculate. 



The markings of the elytra recall Physimerus ephippium Clk. 

 and its allies. 



One example.
