MISCELLANEOUS NEW CHALCID-FLIES OF THE 

 HYMENOPTEROUS FAMILY ENCYRTIDAE

The family Encyrtidae is remarkable for its incomparably ridi 

 and diverse display of generic characters, in sharp contrast with 

 certain other Chalcidoid families, such as the Pteromalidae, which 

 are much more uniform in both appearance and structure. The 

 number of genera of the Encyrtidae, although now amounting to 

 over 300, will be gradually increased by future work, and the im- 

 mensity of the group can be appreciated only by those who have 

 had occasion to arrange or study collections of small parasitic 

 Hymenoptera, especially from tropical regions. Only a small 

 amount of work has yet been done on these insects from the Tropics, 

 however, except by Girault in Queensland, Australia, so that doubt- 

 less many interesting genera and species await description. The 

 family is also by no means poorly represented in the temperate 

 regions of the globe, and a few species have been recorded even from 

 the Arctic Zone. 



In the following pages seven new genera and nine new species are 

 described, seven species of which come from North America or the 

 West Indies, and one species each from Fiji and Victoria, Australia. 

 This material has been reared in small part by myself, but for the 

 most part it has been received for determination at various times 

 and from various sources. Seven of these species were reared from 

 Coccidae, and one was reared from /Sympherohius, which preys upon 

 Coccidae. The habit of the new species from Fiji is unlmown, as 

 the type specimen was not reared. 



This paper gives the results of a series of studies made at the 

 Graduate School of Tropical Agriculture and Citrus Experiment 

 Station of the University of California at Riverside, California. 



VOSLERIA, new genus 



Vosleria is evidently allied to the Dinocanrsis and Leptomastix 

 group of genera, and although running with difficulty in Ashmead's 

 table to the Leptomastix or Ectro7na couplets, it does not agree 

 closely in details with any of the included genera. In Girault's table
