Commenting upon this classification, Mr. Howard stated that, 

 in his opinion, the Signiphorinas, which Mr. Ashmead had made 

 a subfamily of the Encyrtidae, should be given family rank, a con 

 clusion which Mr. Ashmead was hardly prepared to accept, re

 in making it a subfamily. 



Mr. O. F. Cook presented the following paper : 



HUBBARDIA, A NEW GENUS OF PEDIPALPI. 



By O. F. COOK. 

 The family Hubbardiidae* differs from all other Pedipalpi in hav- 



* While this paper is passing through the press (March, 1899) it is found 

 that the generic name Schizonotus Thorell, on which the family designa 

 tion Schizonotidae was based, was preoccupied by Ratzeburg in 1852, 

 although omitted from Scudder's " Nomenclator." A change being thus 

 necessary, I am deeply gratified at the opportunity of suggesting the use 

 of the name Hubbardiidae, as a further tribute of respect and admiration 

 for the recently deceased discoverer of Hubbardia. 



To replace Nyctalops Cambridge (Ann. and Mag. Nat. Hist., 1872 (4), 

 X, p. 410), and Schizonotus Thorell (Ann. Mus. Civ. Genova, 1888, XXVI, 

 p. 358) the name Schizomus is proposed, with 6". crassicaudatus (Cam 

 bridge /. c., p. 411), as type. Instead of Tripeltis Thorell (Ann. Mus. 

 Civ. Genova, 1889, XXVII, p. 554), which was also preoccupied (Cope,
