484. SUPPLEMENT. 
One pair, the male from Carrillo captured by Mr. Lankester. This species is not 
closely related to any of those described in this work, and it is remarkable on account 
of the fulyo-setose tarsi and the long slender rostrum in both sexes. The oblique 
submarginal vitta on the prothorax is almost obsolete in one specimen (¢ ).
