458 INSECTA MADERENSIA. 



prothoraces, by their more elliptical eyes, somewhat shorter and more incrassated 

 antennae, and by theu' prosternum being produced behind into a flattened lobe, 

 "O'hich (when long enough) is received into an impression in front of the meso- 

 sternum. The main distinctive featm'es in the parts of then* mouth consist in 

 the dilated, apicaUy truncated, and more or less seciu-iform terminal joint of their 

 maxillary palpi, in their narrow and pointed inner maxillary lobe, and in their 

 somewhat ample and anteriorly bifid ligula. The sole Madeiran representative 

 (hitherto detected) of tliis immense and universally distributed group is, outwardly, 

 of such an exceedingly anomalous structure, that, before examination, I had 

 imagined that it would probably constitute a separate genus. Its oral organs 

 however differ in scarcely any respect from the ordinary type ; and I have been 

 content therefore to propose for it a sithfjeneric name, in case that future re- 

 searches should discover, as is not unlikely, other species moulded after the 

 same external pattern, and thus render it desirable to detach them from the parent 

 mass.

Hnbitat in Maderil sylvatica, super folia Fragarice, rarissima : tria specimina, ad Kibeiro Frio mense

C. ovate, convex, sbining, when alive of a very brilliant green, — which however becomes obscurer 

 after death. Head and prothorax impunctate, except towards the sides of the latter, — which are 

 broadly (though not very distinctly) margined, and have a few large, scattered punctures (which 

 are sometimes however nearly absent) along the edges and within the submarginal depression. 

 Elytra with longitudinal series, somewhat arranged in pairs, of very minute and obscure punc- 

 tures (but not striated), the space between each pair having a tendency to be raised, — both the 

 punctures and ridges however being most apparent towards the sides, and nearly evanescent on 

 the disk ; convex and laterally compressed, particularly behind, and greatly wrinkled (or uneven) 

 towards the lateral margins, along their entire length ; the suture with a slightly violet tinge. 

 Antenna (especially towards their apex), and the tarsi, obscurer than the rest of the surface. 



A truly indigenous insect, and perhaps one of the most anomalous of the 

 Chrijsomelce hitherto described, — its laterally compressed form, and the curiously 

 shriveled, or collapsed, sides of its el}i;ra giving it a most remarkable appearance, 

 u n l ik e anji:hing else with which I am acquainted. Xt fii'st sight indeed this 

 wrinkled, or corrugated, structure might seem to be the result of a lapsus naiurcB, 

 as though the creature had been imperfectly developed; nevertheless, a closer
