500 SOUTH AMERICAN HALTICIDAE (cOLEOPTERa) 



the middle, the surface thickly punctate and with sparse light pubescence; 

 elytra with basal depression barely indicated, surface with sparse light pubes- 

 cence and longer hairs; claws appendiculate. 



Two examples. 



Loxoprosopus cyanipennis nov. sp. 



Head and elytra brilliant greenish cyaneoiis, thorax more 

 coppery, with the base fairly clothed with golden pubescence, 

 body below black, legs flavous, anterior tibiae and tarsi cloudy, 

 antennae dark fuscous, joints nine to eleven flavous. 



Type. — 9 ; Cachabe, Ecuador; low c; XI, 1896, (Rosenberg). 

 Length 4.5 mm. 



Clypeus smooth, divided by a median and two side carinae, frontal tubercles 

 well developed, vertex and neck smooth, shiny, nearly impunctate; antennae 

 reaching nearly to apex of elytra, joints one and three much the longest; thorax 

 transverse with straight sides, all the angles prominent, transversely depressed 

 at base, the depression clothed with golden hair; scutellum black, elytra deeply 

 punctate striate, becoming somewhat obsolete at tip, a fairly well marked 

 transverse basal depression, the surface very sparsely clothed with dark hair; 

 body beneath shining black, claws appendiculate. 



Apparently allied to L. caeruleus Clk. (not in my collection), 

 especially in the pubescence of the thorax. Type unique. 



Loxoprosopus clarkii nov. sp. 



Head black, clypeus and face yellow, thorax yellow, elytra 

 dark bluish black, grossly punctate striate, a submarginal line of 

 ashy pubescence from the shoulder to the apex, joining a much 

 narrower sutural edging of the same pubescence, legs flavous, 

 anterior tarsi and tip of the tibiae darkened, joints nine to eleven 

 of antennae (except the extreme tip) flavous. 



Type. — 9 ; Cachabe, Ecuador; low c; I, 1897, (Rosenberg). 

 Length 4.5 mm. 



Front smooth, vertical, with a plain median carina and a deep transverse 

 frontal clypeal groove, a fairly well marked transverse depression between 

 the eyes, back of the head smooth ; antennae longer than the body with first 

 joint strongly swollen at about the upper two-thirds; joints three, four and five 

 elongate, the third the longest; thorax transverse, depressed, slightly con- 

 stricted behind, surface duU with fine yellow pubescence, scutellum black; 

 basal depression of the elji,ra indicated only by a slight raising of the scutellar 

 region, punctures of about the same style as humeralisCik., body beneath black, 

 claws appendiculate. 



Type unique.
