and Species of Heteromera. 473 



The Titazna Ericksom, White, proving upon examination 

 to be generically distinct from Titcena, has caused me to 

 notice the species of that genus (which are peculiar to 

 Australia), and to describe some that are new; the New- 

 Zealand group of three species forms a new genus (Artystona), 

 the characters of which are fully stated in the body of the 

 paper. I have also thought it interesting to describe the 

 cognate group of species found in New Caledonia which con- 

 stitute my genus Callismilax, some of the species of which 

 have already been described by Montrouzier as belonging to 

 the genus Strongylium. 



The Opatrinus convexus, Fairmaire, described from examples 

 coming from Wallis Island, occurs also in New Zealand ; it 

 will form the type of a new genus, totally removed from 

 Opatrinus 7 and must be placed not far from Scotoderus, 

 Perroud *. 



The Opatrum tuber •culicostatum, White, evidently does not 

 belong to that genus ; as M. Miedel, of Liege, is at present 

 engaged upon a monograph of the Opatrides, I leave this in 

 his hands. 



I have not as yet been able to consult the work by Blanchard 

 containing the description of his Bolitophagus angulifer (from 

 New Zealand) ; I, however, strongly suspect it to be identical 

 with a species I have in my collection, and which I refer to 

 the genus Bradymerus, Perroud : this genus is placed by its 

 author with the Bolitopliagides ; to me it seems more natural 

 to place it with the true Tenebrionides. 



I have received from Mr. Pascoe examples of the Seleno- 

 palpus cyaneus, Fab. ; these appear to me to be specifically 

 identical with the type specimens (in my possession) of 

 8. chalybeus, White. The characters of this genus lie rather 

 in the form of the hind femora and tibia? in the male (of which 



* The description of Scotoderus cancellatus, Perroud, very accurately 

 applies to examples of Iphthimus cancellatus, Montrouz., obtained from 

 the collection of Doue. Dechius, Pascoe, is but another name for Scoto- 

 derus ; and Perroud's, having priority, must stand. The mesocoxal cavi- 

 ties being widely open externally, revealing the trochantins, at once re- 

 moves this genus from the position where Perroud has placed it, viz. in 

 the vicinity of Antimachus (a genus of Ulomides) ; as I have previously 

 stated (Trans. Ent. Soc. 18(58, p. 205), its true position appears to me to 

 be near to Bius. The Scotoderus cancellatus is very near to aphodioides 

 (Dechius), Pascoe, but may at once be separated from the latter by its 

 smaller size, more finely punctured prothorax, the more distinctly crenated 

 striae of the elytra (especially those by the suture), with the intervals 

 distinctly punctulate. Scissicollis (Dechius), mihi, may instantly be distin- 

 guished from both by its sparsely punctured and not at all rugose head, 

 the very strong (and punctured) groove down the middle of its prothorax, 

 the remainder of the surface of this part being almost impunctate.
