130 DE. L. O. HOWABD ON THE 



suggest even the most tentative generalizations on the material 

 studied. It is true that a number of Chalcididse from Central 

 America have been described by Mr. Cameron, but Mr. Smith's 

 method of collecting differed so greatly from that of the 

 naturalists engaged in collecting for the ' Biologia Centrali- 

 Americana,' that it is not fair to generalize on the rather 

 radical difference in character between the specimens studied 

 by Mr. Cameron and those collected by Mr. Smith.

Mr. Smith took in all 27 male and female specimens of this 

 species. They were captured under diverse conditions. Several 

 came to light at night, others were flying at sunset about cocoa 

 orchards, and others were found under decaying leaves on 

 a damp rock. It is apparently a very abundant Indian and 

 Central American species.

There are 21 male and female specimens of this species from 

 Grenada, exhibiting a great variation in size, and taken by 

 Mr. Smith under the same diverse conditions as the preceding 

 species.
