gent and separated throughout by a depressed median area. 

 Scrobes not open posteriorly. Eyes subrotundate. Prothorax 

 (3-5 X 4-5 mm.), transverse, rounded on sides, widest across 

 middle, apex with a definite postocular sinuosity, lobes small ; 

 disc with a faint collar-impression, regularly and closely 

 covered with fine rounded setigerous granules. Elytra (9x6 

 mm.) not greatly ampliate, but apex abruptly rounded, 

 almost subtruncate : base truncate, humeral angles not pro- 

 minent. Disc with sculpture confused, with small shallow 

 depressions in striae, separated by transverse setigerous 

 ridges ; interstices not prominent, barely traceable apart from 

 the intrastrial ridges, finely granulate in single series, occa- 

 sionally duplicated ; sides punctato-striate. Metasternum with 

 a feeble longitudinal concavity. Ventral segments, third and 

 fourth flat, together equal to fifth segment ; fifth segment 

 rather deeply concave, deepest along posterior edge, which is 

 slightly raised ; forceps with membranous tips protruding at 

 sides. Legs simple. On dissection, forceps small, chitinous, 

 more or less united at base, no median vertical plate ; penis 

 with apex obtusely rounded, upturned and feebly mucronate. 

 9 . Differs in its more ovate form, with apex of elytra more 

 gradually rounded ; beneath convex, the intermediate seg- 

 ments rather longer, fifth segment with a J_-shaped impres- 

 sion. Dimensions : (J. 14 x 6 mm.: 9- 15x6 mm.; P. 4 x 5, E.

This species is the one considered by Macleay to be T. mor- 

 hillosus, Boisd., but the type of that species is quite a differ- 

 ent insect, allied to T. orthodoicus Lea. Erichson has de- 

 scribed a Tasmanian species as T. morhillosus, which, fi'om 

 description, I believe to be T. pe?iicillatus Macl., an insect 

 closely allied, but differing in clothing, elytral granules, etc. 

 The present species, which has been referred by Lea to Psali- 

 dura, may be recognised among its immediate allies by its 

 uniform dingy black appearance.
