18 BULLETIX 1336, U. S. DEPARTMENT OF AGRICULTURE 
Winthemia quadripustulata Fab. 14 was reared by F. M. Moody 
at Charleston, Mo., and by the writer at Knoxville, Term., in 1916. 
The caterpillars from which the latter were reared each bore two 
small, oval white eggs on its thorax; and, when swept from the field, 
one was a prepupa, while the other was still feeding. The former 
pupated a few days after capture, and when examined three days 
later a large puparium was found filling over two-thirds of its interior, 
leaving only the end of the abdomen empty- The other caterpillar also 
pupated; but in this case the parasite larva, a yellowish-white 
maggot 8 millimeters long, emerged from the pupa and formed its 
puparium outside. 
In addition to the foregoing Diptera, Sherman (10) listed as reared 
in North Carolina the following five species : 
Bombyliidae: Anthrax lateralis Say. 
Tachinidae: Euphorocera jloridensis Tns., Exorista boarmiae Coq., 
Frontina aletiae Riley. 
Sarcophagidae : SarcopJiaga cimbicis Tns. 
HEMIPTERA 
NABIDAE 
Nobis ferus L. 15 — This slender gray bug has been found hi the field 
at different times feeding on the young Plathypena scabra. As it has 
usually been found exceedingly abundant in infested fields in Tennes- 
see examined by the writer, it undoubtedly aids considerably in the 
destruction of the caterpillars. The nymphs as early as the first and 
second instars have been observed to attack and kill the young 
arvae. Bugs kept in captivity deposited eggs in rows along the 
stems of the alfalfa plants, each egg inserted deeply, with only one 
end showing on the surface as a tiny white spot. 
PENTATOMIDAE 
Podisus maculiventris Say, the spined soldier-bug, has been found 
numerous in infested fields and undoubtedly kills many of the cater- 
pillars. One bug was found in the field with a Plathypena scabra 
larva pierced by its beak. This specimen was determined as Podisus 
maculiventris Say by 0. Heidemann. Individuals kept in captivity 
fed readily on the caterpillars, one destroying five in the course of 
five days' captivity. It pierced the larva with its beak and sucked 
its contents, leaving only a shrunken remnant of skin and solid parts. 
FUNGOUS DISEASE 
In the fall of the year great numbers of larvae are killed off by the 
fungus Botrytis rileyi Farl. 16 Both at Knoxville and Nashville, Tenn., 
they have been severely attacked by this disease, and similar reports 
have come from Hagerstown, Md. 
14 Three specimens from Tennessee determined by W. R. Walton. 
»5 An individual found by the writer feeding on a Plathypena scabra larva was identified by Herbert 
Osborn as Xabis ferns L. 
16 Infestation on Plathypena scabra larvae collected by the writer at Knoxville, Tenn., was determined as 
this fungus by Alden T. Speare.
