INSECTA MADERENSIA. 425 



23i'e\dous genus and the following one by its somewhat more incurved mandibles 

 and slenderer palpi, — the latter of which have their apical joint more secnriform 

 than in Stromatliim, but considerably less so than in Blahi>iotus. It is very often 

 united with CallkUum, from which perhaps it is scarcely in reality distinct. 

 Nevertheless it differs fi-om the normal state of that group in having its antennae 

 longer and more setaceous, the terminal articulation of its palpi more incrassated, 

 and by the more or less glabrous prominences of its prothorax.

 P. depressus rufo-testaceus punctatus pubescens, prothorace inaequali subtuberculato, elytris testaceis.

Phymatodes variahile, Muls. Longic. de France, 47 (1840). 



Habitat in vinetis hortisque Maderfe, sub cortice arborum laxo, sestate rarior. 



P. smaller than the last, and mucb more depressed, linear-elongate, rufo-testaceous, distinctly and 

 rather coarsely punctured, and clothed, though not very densely, with pubescence. Antenna 

 very long, with a few rigid hairs at the summit of each joint, evanescent in the apical ones. 

 Prothora.v rather small, and rounded at the sides ; its upper surface unequal, with a large (though 

 obscure) tubercular subglabrous prominence on either side of the disk, and an elongated central 

 one (forming a portion of the dorsal line) behind. Elytra rather paler than the prothorax ; much 

 depressed, and with very obscure indications of a slightly oblique longitudinal ridge down each. 

 Antenna and legs concolorous with the head and prothorax. 

 Var. /3. piceous-black ; elytra with- either a slightly rufescent or a violet tinge; antenna and tarsi 

 more or less fusco-ferruginous. 



The common European F. variabilis appears subject in Madeira to much the 

 same alternations of colouring as in more northern latitudes, — from whence indeed 

 it may very possibly have been originally introduced. It occiu'S, at rather low 

 elevations, in the \dcinity of vineyards, — secreting itself l)eneath the loose bark of 

 the trees upon which the vines are trained. In such situations I have taken the 

 pale, or normal, state rather abundantly at Santa Anna during the early summer 

 months. Of the dark variety I have seen hitherto but a single specimen, pre- 

 sented to me by the Hev. R. T. Lowe from the collection of the late Dr. Heinecken, 

 by whom it was captured many years ago near Funchal.
