very stout; tibia? dilated towards apex, lower apex with a short 

 stout spur; three basal joints of tarsi short, 3rd deeply bilobed, 

 claw-joint stout, longer than the rest combined; claws Long and 

 strong. Elongate, depressed, feebly clothed. 



Of the five blind genera described by Mr. Wollaston as belong- 

 ing to the Cosso7iidce* Halorhynchus has the funicle five-jointed; 

 Raymondionymus, Alaocyba and Onycholips have it six-jointed; 

 whilst only Lipommata has it seven-jointed. The last genus 

 (from Madeira) is perhaps the nearest ally of the one above 

 described, although the only known species is described as having 

 a convex body, ovate outline, porrect shoulders, short antenna 1 , 

 not quite contiguous anterior coxa?" and pseudo-tetramerous tarsi 

 with the 3rd joint simple. I prefer therefore to place it in the 

 true Cossonides in the vicinity of Lipommata. 



Tasmanica myrmecophila, n.sp. 



Very pale testaceous and slightly shining. Clothed with rather 

 long and very sparse pale hairs, sparser on prothorax and longer 

 on elytra than elsewhere. 



Head and rostrum densely and rugosely punctate, hairs of the 

 latter curved inwardly in front. Prothorax with large deep and 

 regular punctures which cause the sides from some directions to 

 appear serrate. Elytra with regular series of large round deep 

 punctures, slightly larger than those on prothorax but not so 

 close together ; interstices gently convex, very feebly (more 

 noticeably so towards sides than suture) rugulose. Under surface 

 with large punctures, but which are neither deep nor close 

 together. Length (including rostrum) 1#, width ^ mm. 



Hob. — Hobart, Tasm. 



The specimen described is the only one I have ever seen, 

 although the insect has been repeatedly searched for. It was kindly 

 presented to me by Mr. J. R. Norman who obtained it under a 

 stone in the nest of a small red ant, and who thought at the time 

 of capture that it belonged to the Pselaphidce.
