1. Enoclerus lugubris Erichson. (Plate 6, fig. 1.) 

 Clems Ivgubris Erich. Archiv fiir Naturgeschichte, XIII, 1847, p. 85. 



Originally described from eastern Peru, it has since been re- 

 corded by Herr Sigm. Schenkling as occurring in Bolivia. This 

 species was taken at Porto Velho, Camp 39 and Abuna, most of 

 the specimens were, however, captured at the last named place. 



The ante-apical, rounded, elytral maculation is in all the speci- 

 mens a pale orange yellow; the color of this spot is given by Erich- 

 son as "albidis," Schenkling states that these spots are "bald 

 weisslich, bald orange-gelb, selten blutrot," and adds "der Hin- 

 terleib rot, selten mit schwarzer Spitze, der Brust schwarz." All 

 the specimens before me agree with the type as described in ha^'ing 

 the apical abdominal segments, in part at least, black, and the 

 posterior femora pale at base.
