 twice as long as the second. Hind metatarsus as long as the

This is much nearer to the Mexican species, P. angustatus, 

 Kieff., than to P. cyllndricus, but differs in the sculpture 

 of the thorax, the shape of the head, and .other details. 

 Kieffer gives two species of Pseudofoenus as Australian, but 

 P. unguiculatus, Westw., is from New Zealand, and darwinii, 

 Westw., belongs to Hyptioyaster.
