Archytas analis, Fabr. Adult on sweet clover and golden- 
rod in midsummer. Has been bred from tent caterpillar and 
army worm. 
Echinomyia algens Wied. Adult with the preceding. Has 
been bred from a cutworm. 
The second group of species, mentioned in four of the five 
lists, is as follows: 
Trichopoda pennipes Fabr. This appears to occur from 
Argentina to about the latitude of Kansas, and still farther 
north to the eastward, but not in the northwest. It has been 
bred from Anasa and Leptoglossus, plant-feeding Heteroptera. 
Cryptomeigenia theutis Walk. Very widespread but not 
abundant. The adults of Lachnosterna are attacked, and 
presumably allied genera in regions where Lachnosterna is not 
represented. 
Linnemyia comta Fall. Abundant on foliage; has been 
reared from cutworms, and from Laphygma frugiperda (the 
latter an unpublished record of the Bureau). This species 
perhaps more than any other in the second group deserves a 
place in the first, from its very wide distribution. It has 
however been bred only a few times. 
Euphorocera clartpennis Macq. Except for the fact that 
I did not find this species well represented in the Illinois col- 
lection, I should have placed it in the first group; my impres- 
sion is that it is a close second to Winthemia quadripustulata 
as a parasite of lepidopterous larve; it has been reared from 
many species. 
Metacheta helymus Walk. Persistently common, but not 
abundant. Adult on foliage. Until the past summer this 
species had never been bred, but Mr. Gahan and Mr. Hyslop 
both reared it this year from the Army Worm in Maryland 
(unpublished records). 
Metopia leucocephala Rossi. Adult on low foliage and on 
the ground. Common throughout the summer. Has not been 
bred in this country, but in Europe, where the species also 
occurs, it has been reared from nests of Bembex, Halictus, and 
Philanthus, burrowing Hymenoptera. 
Spallanzania hesperidarum Will. Not generally abundant, 
though widespread. A butterfly parasite. 
Peleteria tessellata Fabr, and robusta Wied. Both very 
common species on flowers throughout the country, all summer 
long. Robusta has been bred from Leucania unipuncta by
