Mr. J. S. Baly on six new species of Chrysomela. 93 



and represent as many as nine families, whilst five of the species 

 (i. e. nearly half of the entire number) are Heteromerous. Although 

 it may appear absurd, at first sight, to speculate from such scanty 

 data, it nevertheless is not difficult to decide, even from this material 

 (which, after all, is considerable enough from islands thus minute), 

 to which of the Atlantic groups these intermediate " stepping- 

 stones " are the more akin ; for if we remove the Cercyon centri- 

 maculatum and Blaps gages, which are common to both, from the 

 above list, we shall perceive that, of the remaining nine, eight are 

 most intimately connected with Canarian forms, — whilst two of these 

 (the Hegeter latebricola and Ditylus fulvus) will, in all probability, 

 be found to be absolutely identical with them. The Pterostichus 

 haligena, moreover, is very nearly related to the P. canariensis, 

 Bridle (belonging to a section, Orthomus, which apparently does not 

 exist in Madeira) ; the Harpalus pelagicus is, emphatically, on the 

 Canarian type ; the Acalles Neptunus finds its natural ally in the 

 A. argillosus of Tenerifle ; the Deucalion oceanicus is more akin to 

 the D. gibbus of the Canaries than to the Madeiran D. Desertarum ; 

 and the Opatrum dilatatum is but slightly removed from a representa- 

 tive of the same genus which is found in Fuerteventura and Lan- 

 zarote, — the Helops Leacocianus alone having perhaps more affinity 

 with a species from the Madeiras (namely, the Porto-Santan H. in- 

 femus) than with any of those from the Canaries ; though even of 

 this I have by no means, as yet, completely satisfied myself. So 

 that I think we may fairly conclude from these facts, that the Sal- 

 vages, if indeed they are to be considered as belonging physically to 

 either of the neighbouring groups, are essentially Canarian. 



VIII. — Descriptions of sir new species of Chrysomela from the East. 



By J. S. Baly. 



1. Chrysomela Templetoni. 



C. breviter ovata, valde convexa, obscure nigro-senea, nitida ; elytris sub- 



globosis, obscure rufis, utrisque striis decern punctorum impressorum 



biseriatim dispositis instructis. — Long. 3^-4 lin. 



Very convex, obscm-e nigro-ameous, nitidous ; elytra obscure rufous. 

 Head nearly impunctate ; antenna? black, slender, more than half the 

 length of the body, subincrassate towards their apex. Thorax twice 

 broader than long ; sides slightly dilated from their base to before the 

 middle, thence rotundate-angustate to the apex: above smooth and 

 shining, sparingly impressed here and there with fine but distinct 

 punctures ; sides thickened, bounded within by a longitudinal depres- 

 sion. Scutellum semiovate. Elytra subglobose, smooth and shining,
