long as the scutellum. Median segment very delicately 

 rugulose, with a low longitudinal carina, hind coxre finely 

 granulate. Abdomen long and slender, the first tergite 

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

 four apical tarsal joints ; tarsal ungues small.

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. 

 KieflTer gives two species of Pseudofoenus as Australian, but 

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

 Westw., belongs to Hyptioyuster.
