Blastophag^ or Fig Insects. 



A large collection of these minute wasps, with the 

 various species of wild figs inhabited by them, was made 

 in 1893 and 1894. The collection was delivered to 

 Prof. C. V. Riley, at his urgent request, but since his 

 untimely death Prof. W. H. Ashmead has kindly under- 

 taken the description of this interesting and difficult 

 group.

The very large collections made by us in 1894 both in 

 the Cape Region and at Tepic are now worked up by 

 Prof. Pergande, who writes that the manuscript will be 

 ready before very long, the very large size of the col- 

 lections having made delay necessary. 



Reptiles. — The collections from Baja California have 

 been worked up by Prof. John Van Denburgh, whose 

 papers will be mentioned below. The work on the col- 

 lections from Mazatlan and Tepic is not yet finished,^but 

 is being rapidly pushed by that author.
