Tijye locality . — Carlisle, Pennsylvania. 



Type.—Cfit. No. 24987, U.8.N.M. 



Type, allotype, and two paratypes reared by P. R. Myers, August 

 18-21, 1917, from eggs of a katydid, Microcentrum, species, under 

 Cage No. 1056. Also four paratypes reared at Washington, District 

 of Columbia, April 20, 1891, from the eggs of a 3Iicrocentrum which 

 may or may not have been the same species. 



EUPELMUS POPA Girault. 



Eupelmus popa Girault, Descriptiones Hymenopterorum Chalcidoidicarum 

 Variorum cum Observationibus, pt. 5, 1917, p. 4. (Private publication.) 



This species was described by Girault from five female specimens 

 which are in the United States National Museum under Type Cata- 

 logue No. 21422. These specimens were received from P. J. Van 

 Breemen, by whom they were reared at Curacao, Dutch Antilles, in 

 connection Avith ContaHnia sorghicola Coquillet. 



In addition to the type material the National Collection contains 

 the following material determined by the writer as this species: 

 Fourteen specimens from San Antonio, Texas, reared by C. H. Gable, 

 July 15, 1920, from Contarinia sorghicola under his T. No. 76 ; eight 

 specimens from the same place and the same host, reared by Gable 

 August 18, 1920, and recorded in the Bureau of Entomology, U. S. 

 Department of Agriculture under Webster No. 5357, T. No. 104 ; one 

 female taken at Limones, Cuba, by W. M. Mann on sacks of grain ; 

 eleven specimens bearing lot No. 15, reared by K. K. Kannan at 

 Chumurajhagar, India, July 27, 1915, from a Cecidomyid infesting 

 sorghum ; and six specimens under lot No. 19, from Nanjangua, India, 

 also reared by Kannau from the same Cecidomyid host. 



The material from India was transmitted to the^ writer through 

 the Bureau of Entomology by Mr. C. H. Gable, who stated that the 

 Cecidomyid host from which the parasites were reared had been 

 determined by Dr. E. P. Felt as Contarinia caudata Felt, which 

 species, according to Mr. Gable, " seems to be very close to our Con- 

 tarinia sorghicola^ if not identical." 



The specimens of this parasite from India and those from the 

 United States and the West Indies seem to be identical in every re- 

 spect. Its occurrence in two such widely separated parts of the 

 globe is difficult to explain except upon the supposition that its host 

 has been transported from one country to the other. While not 

 conclusive evidence, the parasite record tends to confirm the sus-
