598 STUDIES IN AUSTRALIAN ENTOMOLOGY, NO. XII., 



Casteln. (following in this MM. Chaudoir and Tscbitscherine). 

 A specimen of Ilouia/ottonia svlandersi, Casteln., agreeing with 

 specimens so named in the Macleay Coll., is before me; it differs 

 from C. latipennis by colour (margins of elytra and prothorax 

 bright green); prothorax with sides not sinuate before base, basal 

 <angles far more obtuse and less marked; elytra more convex, 

 interstices less raised to the summits (widel}' and roundly convex), 

 se^ enth much less carinate, especially near base. Dimensions : 

 Length 27; proth. 5-5 x 85, apex 6-7, base 6-5; el. 13-2 x 10 mm. 

 I believe C. latipennis differs sufficientl}' from C brevis to be 

 regarded as a distinct species. 



Castelneaudia subvirexs, Chaudoir. 



Homalosoma siihvirens, Chaud., Bull. Mosc. 1865, ii., p. 72. 



C. subvirens has remained unknown since Chaudoir described 

 it till now. I have identified it in a species from South Queens- 

 land (Tambourine Mountain) received from Mr. C. French. It 

 seems sufficiently ^vell described to be recognisable; but to show 

 its position in the genus, and to enable the species to which I 

 have applied the name C. subvirens to be recognised, the 

 following brief descriptive note is offered. According to the 

 tabular list of species I already have given in these Proceedings 

 (1899, p. 567), its position would be in section "C." 



Allied to C. angnlosa, Chaud., but differing by upper surface 

 more convex; prothorax not so flat, sides more strongly rounded, 

 lightly sinuate before base; elytra virescent (not black), more 

 convex, space between seventh costa and marginal channel more 

 strongly declivous, seventh interstice less carinate except near 

 base, 8th interstice not separated from ninth near apex. Dimen- 

 sions : Length 26; head 5*25 across eyes; proth. 5-4 x 7-3, apex 

 5*3, base 6; el. 14 x 8*6 mm. 



The intercoxal declivities of prosternum and mesosternum are 

 setigero-punctate. A specimen (^) before me has the anterior 

 tarsi neither dilatate nor squamulose beneath*; abdomen with a 



* This character is very remarkable in a species of section " C," so much 

 so that one wonders whether it may not be merely an individual jDecuharity 

 in the specimen I have.
