granules in single series, on sutural interstice finer and more 

 numerous, becoming larger towards base; second and fourth each 

 with from five to eight granules ; third and fifth with from 

 twelve to fourteen rather smaller, more closely placed, 

 granules ; on all the interstices the granules become more 

 distantly spaced on the declivity. Sides irregularly, some- 

 what rugosely, granulate. Metasternum flat. Third and 

 fourth ventral segments short, together less than fifth ; fifth 

 shallowly excavate with a deep, subquadrate, median fossa, 

 having a small distinct tubercle on either side, posterior edge 

 straight. Obtuse ends of forceps appearing at sides. Legs 

 long ; tibiae with stout setae or spines on undersurf ace : pos- 

 terior tarsi elongate. Dhneiixinint : (J 15 x 7 mm.

The elytral granules vary somewhat in number on the two 

 sides of the elytra, and in different specimens. Most closely 

 allied to T. M-elevatus Lea, but abundantly distinct in 

 having all the elytral interstices granulate. There is some 

 doubt as to whether these two and allied species would not 

 be better included in PsaUdtira ; both have the intermediate 

 ventral segments short, the ends of the forceps projecting 

 externally ; and in T. M-elevatus, dissection shews the 

 presence of a median vertical plate. 



The name T. morbillosus Boisd., has been used by Mac- 

 leay for a very different insect, from Victoria. 



T. orthodonrus Lea, is also closely related, but differs in 

 the elytral graniiles being subconfluent, slightly in the ros- 

 trum, and in the position of the tubercules on the fifth 

 abdominal segment.
