NEW SPECIES OF PSELAPHIDAE (Group TYEINT) 

 BY G. E. BKYANT, F.E.S. 



(Plate XXI). 



v^. 



The Tyrini appear to be rare, and I only succeeded in obtaining 

 14 species belonging to nine genera from Peuang and Sarawak. Of 

 these nine genera, five were found in the nests of ants and termites, 

 and two wei'e taken by beating dead branches in the jungle in the 

 evening, which is probably a proof that they are myrmecophilous, as 

 the Clavigerinae are sometimes met with in the same way. The 

 remainder were collected by sifting dead leaves. It is highly probable 

 that the great majority of the Tyrini are myrmecophilous or termi- 

 tophilous, which would account for their apparent rarity. So far as 

 present known, they are represented by fifteen genera in the Malayan 

 region. Eulasinvs, Labomimis, Pselaphodes, and Lasinits are very 

 closely allied, PseJapliortes being the Malayan representative, although 

 one species occurs in Ceylon. Eidasimis includes one species from 

 China ; Labominvs two species from India and Japan ; and Lasimis 

 two species from India and Japan. I now add a third, rather doubt- 

 fully, to Lasinus Sharp, as it does not seem to require a separate 

 generic name. We already have over 488 genera for the Pselaphidae, 

 for probably under 3,700 species. Among the species collected, which 

 I am able to determine, are the following : Taphrostethus hamotoides 

 Sell., Sarawak, Quop ; Pselaphodes villosulus Westw., Sarawak, 

 Mt. Matang and Mt. Merinjak ; Ancystrocerus punctatus Ratfr., 

 Penang ; Tyrodes davatns Eaffr., Sarawak, Mt. Matang (described 

 from a specimen from Singapore) ; and P?eudophanias crihricoUis 

 Raffr., Penang.

^ . Oblong, castaneous, rugosely pimctured, and with short golden 

 pubescence. Head about a« long as broad, sub-triangular, attenuate in front, 

 from eyes to base rounded ; frontal tubercvxle sulcata in middle with a fovea at 

 its base ; two large depressions between the eyes, and a fovea in middle near 

 base ; eyes large and prominent ; two sharp spines on each side of head, one 

 projecting under the eye and another between eye and base. Maxillary palpi 

 with joint 2 long and slender, slightly curved, with the apex broader, with a 

 spine at apex on outer margin ; 8 shorter, irregularly triangular, with a spine 

 on outer angle ; 4 with basal half rounded on outer side, inner margin straight 

 from base to apex, with apex acute. Antennae rather stout, with a well-defined 

 3-jointed cluli ; joint 1 long, cylindrical ; 2 much shorter, sub-qviadrate ; 3 — 8 

 about equal, obconical, each shorter than 2 ; 9 much longer, broadening to
