 broad, sides nearly parallel, rounded 

 anteriorly, coarsely but sparsely punc- 

 tate except for a smooth longitudinal 

 median surface; the collar densely,

Described from a single specimen taken in a nest of Aphoenogaster 

 relicta at Diquini. The species is named after Dr. John B. Terres, 

 United States Consul General to Hayti, in recognition of his 

 interest in the fauna of the island. The only other species of 

 Pseiidisobrachium known to occur in the West Indies are P. 

 collinum and P. albipes which were described by Ashmead from 

 males taken in St. Vincent. Besides terresi the habits of only 

 five species of this genus have been recorded and these all live
