but terminated before middle : with clearly defined punctures, 

 but smaller, sparser, and more irregularly distributed than 

 on prothorax. AlxJoineu with a narrow carina on each side 

 of second and third segments : under-surface convex, the first 

 and second segments conspicuously fringed with somewhat 

 trolden clothine:. Leqi^ unarmed : front tibiae somewhat curved 

 and thickened in middle. Length, 2A mm. 



Halt. — Queensland: Townsville (H. H. D. Griffith, from 

 F. P. Dodd). 



The specimen described is probably a female, but the 

 peculiar lateral foveae of the prothorax i-ender the species 

 remarkably distinct. It is allied to T. hrevicornis (also from 

 Townsville), bvit is readily distinguished from that species by 

 the absence of the median ridge from the second dorsal seg- 

 ment of abdomen ; the upper surface of the abdomen is shin- 

 ing, whilst in T. hrevironiis it is subopaque (a character 

 omitted from the original description). 



The species is almost certainly myrmecophilous or termito- 

 philous, but there was no indication as to how the type was 

 obtained.

O*. Reddish-castaneous, head and prothorax somewhat 

 darker. Rather densely clothed with long, yellowish pubes-

Ucdd rather elongate, with two small subbasal fove?e, 

 antennary ridges rather long and parallel, the dividing groove 

 not. very deep. Eyes small and prominent. Antennae long, 

 first joint (from the side) longer than second and third com-
