82 Mr. F. Smith on some neiv Genera and Species 



insertion of the antennae, the yellow colouring extending obliquely 

 upwards on each side ; a yellow spot in front of the ocelli, and two ob- 

 lique stripes behind them ; the mandibles with their tips black ; the 

 antennae fulvous beneath and rufo-fuscous above. Thorax : the pectus, 

 the mesothorax, and base of the metathorax above, black ; the meso- 

 thorax with two longitudinal yellow lines, which also cross the sides 

 of the scutellum ; a line over the tegulag, the post-scutellum and two 

 oblique lines beneath it, yellow ; a black line down the centre of the 

 metathorax; the wings fiavo-hyaline, the nervures pale ferruginous, 

 and a yellow spot on the tegulae. The abdomen petiolated, entirely 

 yellow, and very smooth and shining. 



This is a fine addition to the division of the genus Philanthus 

 which has the abdomen petiolated, of which Klug has formed the 

 genus Traehypus ; but having hitherto adopted the neuration of the 

 wings as the primary character of generic subdivision, I use Klug's 

 name merely as a sectional one. This insect was discovered by 

 Mr. H. "W. Bates at St. Paul, Brazil. Seven species of the petiolated 

 PMlantlii are now known.

 legs ferruginous ; the anterior and intermediate tibiae, the posterior pair 

 outside, the basal joint of the posterior tarsi beneath, the posterior coxae

 dark fuscous stain on the margin of the anterior pair beyond the stigma, 

 the posterior pair slightly stained at their apex. Abdomen : a yellow
