30O REVISION OF THE GENUS ^'OTONOMUS, 



I have compared my specimens with the type specimens of /Y. 

 cyaneocinctus, Macl., and have considered it a distinct but closely 

 allied species on account of the juxtabasal sinuosity of the sides 

 of the prothorax; this, however, is a feature that requires more 

 study to determine its true value in the genus Notonomus. It is 

 nearly allied to N. nitidicollis, Chaud., with which it agrees 

 generally in shape of head, antennae, labrum, interstices of elytra, 

 ct:c., but differs by the shape of the prothorax (which is of wider 

 form with the sides less rounded, less narrowed to both apex and 

 base, much wider across base); the elytra more depressed, more 

 lightly declivous to apex, more lightly rounded on sides, less 

 deeply striate, interstices less convex.

Feronia i^Pterostichus) viridilimbata, Casteln. , Trans. Roy. Soc. 

 Vict. 1868, viii. p. 215; F. (Pt.) viridimaryinata, Casteln., l.c.^ 

 p. 216; N. viridilimbatus, Chaud., Ann. Mus. Civ. Genova, 1874, 

 vi. p. 584 ; N. cyaneocincfus, Macl., Trans. Ent. Soc. N.S.W., 

 1871, ii., p. 108. 



I offer the following translation of Chaudoir's note on N. viri- 

 dilimbatus, Casteln., = iV. viridimarginatus, Casteln. : Length 

 12*5-15 mm. Resembling most closely N". nitidicollis, from which 

 it differs by the posterior angles of the prothorax which are sub- 

 obtuse, not preceded by a sinuosity, and not forming any lateral 

 prominence. Its habitat is the same, and perhaps it will be found 

 to be only a variety. 



I have seen the types of J^. cyaneocinctus, Macl., in the Aus- 

 tralian Museum, Sydney, and have the following note, made with 

 these type specimens before me: — Differs from S. viridicinctusi 

 Macl., by the sides of the prothorax not the least sinuate before 

 the base; the elytra have the shoulders dentate; the form of the 

 prothorax is intermediate between A\ violaceomarginatus, Macl., 

 and iV. viridicinctus, Macl., (=i\r. nitidicollis, Chaud.), being 

 more narrowed behind than in N. violaceomarginatus, and less so 

 than in N. viridicinctus.
