By ARTHUR M. LEA. 



[Read 10th March, 1910.] 



Mr. Jas. A. Kershaw, of the National Museum, recently kindly 

 allowed me to examine the following Pselaphidae, of the Howitt 

 collection, bearing King's original name labels: — 



Ctenistes vernalis, King (Trans. Ent. Soc, N.S.W., 

 I., pp. 40, 102, 300). 



Rytus punctatus. King (/. r. pp. 103, 303). 



R. viCTORiAB, Kingi (/. c. p. 304). 



Tyrus howitti, King2 (/. r. p. 301). 



Bryaxis ater. King (/. r. j. 309). 



Bythixus NIGER, King (/. r. p. 312). 



EupLECTUs Excisu!^, King (/. r. p. 313). 

 All of these T re-mounted so as to examine the under sur- 

 face and legs. As the original descriptions are extremely brief, 

 more detailed ones may be acceptable to workers in the family. 



Ctenistes vernalis, King (now Ctenisophns vernalis. King). 



King's label, "Ctenistes vernalis, R.L.K. (Tmesiphorus ver- 

 nalis). Paramatta." 



Two specimens (sexes) from the original locality, and prob- 

 ably therefore co-types. They are certainly different to the 

 species identified by myself (from comparison with the type, 

 but without examination of the under surface), sent to Raffray 

 under that name, and described by hinr' ; and which species 

 has the abdomen very feebly impressed in the male. 



The supposed co-types exactly resemble that species on the 

 upper surface, and have the antennae as in both sexes of that 

 species, but the third ventral segment has a rather strong
