brought the number of adults up to several hundred specimens from these 
different localities. Figure 1 shows the known distribution of the insect. 
In recent years various members of the Bureau of Entomology, and 
others, have reared B. funebris , together with miscellaneous insects 
emerging from both clover and alfalfa seeds. These specimens were ex¬ 
amined and it was found that H. medicaginis was reared from alfalfa 
seed pods infested by B . funebris as follows:

CLASSIFICATION AND DESCRIPTION 
H . medicaginis belongs to the hymenopterous superfamily Chalci- 
doidea, family Pteromalidae, subfamily Pteromalinae. Specimens reared 
Fig. 1.—Map of the United States, showing the known distribution of Habrocyius medicaginis. 
by the writer from B. funebris in alfalfa seeds at Yuma, Ariz., were 
described by Gahan as a new species. 1 
The description of the female is as follows: 
Length about 1.7 mm. Head and thorax closely punctate, the punctures on the 
medial portion of the mesoscutum slightly larger than those on the scapulae and 
scutellum; antennae with two ring-joints; pedicel and first funicle joint, excluding
