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 Avhich of the Atlantic groups these intermediate " stepping- 

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

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

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

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

 (the Hegeter latehricola and Ditghis fulvus) will, in all probability, 

 be found to be absolutely identical with them. The Pterosticlms 

 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. argillosiis of Tenerifie ; the Deucalion oceanicus is more akin to 

 the D. gibhus 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 Leacodanus alone having perhaps more aflinity 

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

 fernus) 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 faiiiy conclude from these facts, that the Sal- 

 vages, if indeed they ai-e to be considered as belonging physically to 

 either of the neighbouring groups, are essentially Canarian.

 By J. S. Baly. 



1. Chrysomela Tempiletoni. 

 C. breriter ovata, valde convexa, obscure nigro-aenea, nitida ; elj^ris sub- 

 globosis, obscirre rufis, utrisque striis decern punctorum impressorum 

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



Very convex, obscure nigi-o-seneous, nitidous ; elHra obscm-e rufous. 

 Head nearly impunctate ; antennae black, slender, more than half the 

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

 broader than long ; sides slightly dUated 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 distinet 

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

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