PERILAMPUS, A SECONDARY PARASITE ON SARCOPHA- GIDS AND TACHINIDS PARASITIC ON KATYDIDS AND LONG-HORNED GRASSHOPPERS
Ford1 reports finding a planidium of Perilampus attached to a long-horned grasshopper, Conocephalus fasciatus. She considers it quite improbable that Conocephalus is the true host of the Perilampus, and that quite likely the planidium is a secondary parasite of some parasite of Conocephalus, because Perilampus has been reared as a secondary parasite from several species of Sarcophagids, though not from Sar- cophagids on long-horned grasshoppers,.*- I have reared a Perilampus n. ~ p . ~ from one of three puparia collected from the cell of the digger wasp, Ammo- bia penmylvaniea which uses katydids, Microcentrum rhorn- Mfolium (M. laurifolium) for provisioning her cells. The other two puparia yielded a Brachymeria n. sp., and a Sar- cophagid fly. The fly was in too poor a condition to allow of identification beyond Sarcophagidse. The puparia, which were all identical, in structure, were new and as yet uniden- tified, making it impossible to use them as a means of iden- tifying the fly. The find at least establishes the fact that Perilampus is a secondary parasite on a Sarcophagid para- sitic on katydids.
From a collection of over fifty puparia of the Tachinid, Senotainia trilmeata (V. d. W.) found in the cells of the same digger wasp, I reared 2 specimen of Perilampus hya- linus (Say). This establishes the fact that Perilampus is a secondary parasite on Senotainia trilineata parasitic on katydids. I have also reared, however, S. trilineata from 1. N. Ford, Canad. Ent,, 54:199-204, 1922. 2. H. S. Smith, U S Dept Agr, Bur Ent, Tech Ser 19 (4):33-69, 1912. 3. E. 0. G. Kelly, Jour. Agric. Res., U. S. Dept. Agr., 2:435-445, 1914. 4. Identifications were made by the staff of the Bur. Ent. and Plant Quar., U. S. Dept. Agr. as follows: Orthoptera, A. N. Caudell; Perilamphus, A. B. Gahan; Sarcophagids, J. M, Aldrich and C. T. Greene.

19361 Perilampus, a Secondary Parasite 85 puparia found in the cells of the digger wasp Ammobia, ich- neumonea which provisions her nest with long-horned grasshoppers of the species Neoconocephalus ensiger (Con- ocephalw ensiger) and Conocephalus attenuatum (Xiphi- dium attenuatum). This confirms the opinion of Ford that the planidium found in Conocephalus fasciatus is a sec- ondary parasite of a Tachinid parasitic on long-horned grasshoppers, in this case Senotainia trilineata.
