(jieiiiis Pegoscapus Cam. (1906). 



Pegoscapus Cameron, Ann. Estacion Centr. Agronom de 



Cuba, p. 275 (1906). 

 Genotype P. lotigiceps Cam., loc. cit., p. 276. 



In " Cenera Insectoium," 97, p. 386, 1909, Schmiede- 

 kneclit places this genus in the Spalangiini (Pteromahnae), 

 but an examination of Cameron's material proves Pegoscapus 

 to be a true Blastophagine. I have not had access to the 

 original description, and cannot tell whether Schmiede- 

 knecht has merely followed Cameron's opinion or puts 

 forward his own views. The British Museum possesses 

 two $ examples of P. longiceps labelled- — 



{(i) " Cuba, ex Cameron Coll.," acquired in 1906. 

 (6) " Cuba, Havana, Baker, No. 3482, ex Cameron Coll. 

 Type/' acquired in 1914. 



These specimens are specifically identical. The head is 

 wanting in the type, but has fortunately been preserved 

 in the co-type. The neuration is peculiar, being coloured 

 up to the origin of the stigmal vein, beyond which is only 

 a short hyaline stump aloiig the costa, i. e. the post- 

 marginal is practically, and without careful examination 

 appears to be entirely, wanting. In this respect Pegoscapus 

 Cam., approaches Eiseniella Ashm. (Proc. Wash. Ent. Soc, 

 vol. 8, p. 31, 1906), which is a n.n. for Eisenia Ashm. 

 {nee Malm. 1877) (Mem. Carn. Mus., 1, No. 4, p. 233, 1904). 

 Should further investigation prove the identity of Eiseniella 

 Ashm., and Pegoscapus * Cam., the former name will probably 

 have priority, as it appeared on 13th July, while Cameron's 

 paper presumably was not pubhshed till the end of the year. 



The species next to be described is so remarkable that 

 a new geims seems necessary for its reception. For this 

 the name Liporrhopalum, gen. no v., is here proposed. Like 

 Blastophaga Grav., Liporrhopalum has small circular abdo- 

 minal sjjiracles, and the striae on the under surface of the 

 mandibles and their appendages simple. There is a further 

 agreement between the genera in the basal joints (1-5) of 

 the antenna, but from the 6th joint to the end these organs 

 in Liporrhopalum show affniity only with the genus Agaon 

 Dalm. The neuration is unique, and in this respect 

 Liporrhopalum has no close relation except with Eupristina
