closely with Chaudoir's description of N. chalybeus. It differs 

 from N. philippi Newm., by its smaller size. Black, with greenish- 

 blue elytra. Length, 13-14 mm. 



86. N. kershawi SI., is extremely near N. chalybeus Dej., of 

 which it is the representative on the mainland. It exactly resembles 

 N. chalybeus in appearance and colour, but has the prothorax sub- 

 sinuate before the basal angles, which are more strongly marked; 

 the humeral angles of the elytra, too, are more prominent. Hab. —

The lesueuri-group. 



Prothorax with posterior marginal puncture on border at basal 

 angles. Elytra strongly and fully striate; third interstice 2-punc- 

 tate, eighth and ninth subequal, eighth convex. Intercoxal declivity 

 of prosternum flat. Metepisterna longer than is usual in the 

 genus. Four posterior tarsi without spinules beneath costa of 

 external side of first joint; hind tarsi shorter than usual in the 

 genus; onychium glabrous beneath. 



This is a terminal group ; by its short posterior tarsi, and some 

 other characters, it approaches the lateralis-growp. The two species 

 may be separated thus : — 



Elytra with humeral angles edentate 87. N. lesueuri Cast. 



Elytra with humeral angles dentate. 88. N. miles Cast. 



N. miles, as identified by me in my "Revision" of 1902, may not 

 be the species which Castelnau described. I am unable to decide 

 that Chaudoir's description of N. miles Cast., in his "Supplement," 

 could not have been founded on the species I identified as N. miles, 

 but, when we consider that Chaudoir separated N. lesueuri from all 

 the other species of Notonomus, on account of its elongate metepi- 

 sterna ; and that, in the same paper, -he treated of N. miles very 

 fully, it seems difficult to think that the true N. miles has elongate 

 metepisterna. My present view is, that the true N. miles is a 

 species allied to N. kingi Macl., and not N. miles Sloane, but, to 

 prevent changes in nomenclature on insufficient evidence, I now 

 leave the matter as formerly decided by me,* till the examination
