Luteous; anten?ice nearly red ; thorax with three dorsal fuscous stripes; 

 metathorax with base smooth ; apex reticulate 



Length, 32 mm. 



It is yellow, with antennae red and the back of the metathorax orna- 

 mented with three broad indistinct brown lines. The metathorax is di- 

 vided into two very unequal parts ; the first is smooth with the posterior 

 edge projecting and nearly straight ; the second is uniformly flattened, 

 bordered laterally by a projecting line (carina ?) or sort of pad and 

 surmounted by some very distinct oblique pads, of which the first two 

 rise longitudinally on the middle. The abdomen is missing beyond 

 the second segment. 



Type. — Location unknown. 



Undoubtedly an Ophion, but the description is too incom- 

 plete for specific recognition. 

 Distribiition. — Guiana.
