506 SOUTH AMERICAN HALTICIDAE (cOLEOPTERA) 



elytra black with a broad yellow margin from base to apex and 

 on each a narrow curved line of yellow pubescence, starting below 

 the base on the third interspace, following that and gradually 

 broadening out to the fourth, body beneath and legs yellow. 



Type. — Peru. Square light green label. (Callanga?) Second 

 Jac. coll. "n.i.m." Length 4 mm. 



Head with the yellow color just covering the frontal tubercles, back finely 

 punctate; thorax slightly transverse, sides margined, sUghtly sinuate, obso- 

 letely transversely depressed behind so as to appear somewhat swollen at the 

 middle; the yellow parts of the thorax and elytra are covered with golden 

 pubescence, the curved elytral line is only obsoletely yellow and seems to de- 

 pend for its color almost wholly on the pubescence, but the three examples 

 vary somewhat among themselves in this regard. 



Three examples seen. 



Metriotes aeneipennis nov. sji. 



Elongate parallel, head very dark rufous, thorax transverse, 

 rufous, elytra aeneous, striate punctate, with very sparse and 

 short yellow pubescence arranged in rows, scarcely noticeable, 

 except near the apex, where it is seen on the declivity, body 

 beneath black, legs rufous, hind tibiae finely serrate or dentate 

 on outside edge. 



Type. — Cochabamba, Bolivia. (Germ.) 



Clypeus smooth, carinate on either side, joining in a pair of longitudinal 

 tubercles or knobs which separate the antennae and end in a deep rather 

 transverse fovea which occupies the vertex, neck coarsely and closely punc- 

 tate, finely pubescent near the eyes; antennae filiform reaching the middle of 

 the elytra; thorax transverse, margined, sides straight, all the angles sharp, 

 the anterior slightly excurved, surface, coarsely and closely punctate, more 

 thickly at sides, an obsolete smooth callous on each side of the ante median 

 disk; obsoletely depressed on either side and behind, scutellum rufous; eljira 

 punctate striate, becoming obsolete at tip, interstices finely punctulate, broadly 

 but not deeply depressed before the middle, the depression curving upward 

 near the shoulder as usual and bringing out the scutellar region and humeral 

 knobs. Claws appendiculate. 



Eight examples seen with type data, also one in second Jac. 

 coll., probably from the same place, marked "n.i.m." 



Var. A, three examples from same locality with a decided tint 

 of castaneous red to elytra (immature?). 



Var. B, three examples from same locality with elytra bluish 

 aeneous.
