430 INSECTA MADERENSIA. 



margins bright yellow. Elytra with three transverse fasciae, common to both (one of which is 

 sub-basal and broadly interrupted at the suture, the second medial and biarcuate, and the third 

 postmedial and entire), the apex, and the scutellum, bright yellow. Antenna and legs rufo-ferru- 

 ginous ; the former with their basal joint and the apical five or six, and the latter with the central 

 portion of their four anterior femora, infuscated. 



The C. Arietis, so extremely common throughout Europe, may very possibly have 

 been accidentaUy imported into Madeka from more northern latitudes ; and espe- 

 cially so since it is evidently scarce in these islands, it having never come xuider my 

 o^\-n observation in a recent state. The vmique examjile on which its admission 

 into oiu- founa rests was captm-ed many years ago, in the vicinity of Funchal, by 

 the late Dr. Heinecken, — from whose collection it was communicated to me by 

 the Rev. R. T. Lowe.

A ^evKoXiodv Deucalion. 



There is no genus, perhaps, throughout aU the Madeiran Coleoptera, more truly 

 indigenous than Deucalion. Couiined apparently, so far as these islands are 

 concerned, to the remote and almost inaccessible ridges of the two southern 

 Dezertas, it would seem to bid defiance to the most enthusiastic adventm-er who 

 would scale those dangerous heights. Its excessive rarity moreover, even when the 

 localities are attained, must ever impart to it a peculiar value in the eyes of a 

 natm-alist ; wliilst its anomalous structure and sedentary mode of life* give it an 



* AMien we consider indeed tlie apterous nature of Deucalion, its subcomiate elytra, and its attach- 

 ment (at any rate in the lana state) to the interior of the stems of particular, local plants, or its retiring
