Myiophasia aenea Wied. ‘This is the least abundant of the 
fifteen; in spite of the fact that it’ is included in all the lists, I 
have never seen a good, long series. It has been bred several 
times from beetle larve. 
Senotainia rubriventris Macq., and trilineata V.d. W. These 
are always common, especially the latter, on sandy soil in sum- 
mer, where wasps dig their holes. Presumably they parasitize 
these Hymenoptera, as their European congeners do, but 
none have been bred in this country. 
Ocyptera caroline R. D. Common on flowers in late sum- 
mer, especially on goldenrod. It has been bred once from a 
grass-hopper. It makes a fair counterfeit of Ammophila 
when feeding on flowers, with its black and silvery colors and 
red abdomen. 
Panzeria radicum Fabr. This robust species occurs on 
flowers from April throughout the summer. It parasitizes 
caterpillars, and has been found to be single-brooded, wintering 
in the puparium. 
Tachina robusta Townsend. A large species found only in 
spring, often on willow bloom, or sitting on the bare ground. 
It has been bred from larve of moths, and is presumably 
single-brooded. 
Winthemia quadripustulata Fabr. Undoubtedly our most 
abundant Tachinid parasite of lepidopterous larve, from many 
species of which it has been bred. The adults are very common 
on foliage. 
Paradidyma singularis Tns. Only moderately but persist- 
ently common. Bred from burrowing webworms by Forbes 
in Illinois (unpublished record). 
Gonia capitata De G. A very early spring form, even 
earlier than Tachina robusta. In my experience, the dark 
form occurs only in spring, while in late summer there is a less 
common form with yellow abdomen; this if sustained by more 
careful study would argue for specific distinctness, corresponding 
more or less to Williston’s species. Bred from cutworms—the 
spring form. 
Microphthalma disjuncta, Wied. Adults found on bare 
ground in June and July. Not very common westward, per- 
haps not occurring at all in the Pacific Northwest, although it 
occurs in the Southwest. Parasitic on larve of Lachnosterna 
and presumably in the Southwest on allied genera. Probably 
single-brooded.
