Tetbastichus, Holiday. 



This genus is numerously represented in all parts of the worlil 

 and tbe species are exceedingly difficult to separate. Mr. F. 

 Walker, in his * Monographia Chalcididum,' under the genus 

 Girrospilus has described numerous species from England and 

 elsewhere ; but as he gave no tables of his species, and, moreover, 

 seems to have confused several genera under this genus, I have 

 been unable to follow him, and the species described by me may 

 or may not be identical with some of his species. 



The six species in the St. Vincent collection may be dis- 

 tinguished by the follovdng table : — 



Species pale 3. 



Species black or blue-black, smootli or but feebly 



sculptured 2.

 strongly punctate.

yellow T. cupreus, sp. n.

 a. Subopaque. 



Scape and legs, except coxae and femora, 

 brownish yellow ; antennae not especi- 

 ally long ; mesoscutum with a row of 

 punctures at the lateral margins .... T. vulgaris, sp. n.
