from the Island of St. Vincent, 247 



(being coarsely alutaceous beneath the microscope), with its an- 

 tennae rather longer and less compact (the subapical joints of 

 which are less transverse), with its prothorax a trifle shorter, 

 smaller, narrower in front, more rounded (or less straightened) 

 behind (which causes the posterior angles to be more obtuse), 

 with its two basal prothoracic fovese most evidently longer, and 

 with its elytra very much more finely punctate-striated, and 

 nearly free from the strong erect hairs which in its Canarian 

 ally are so conspicuous at the outer margins and shoulders. In 

 their colouring the two species are almost equally unstable; 

 nevertheless the elytral macula of the P. picta, when reduced 

 to a small size, takes less of the semicircular form which cha- 

 racterizes that of the P. Clarkii, — its anterior edge not being so 

 straightened, but more or less angular or dentate on each ely- 

 tron. Both the P. Clarkii and picta differ from the common 

 European P. cadaverina in having, inter alia, the basal joints of 

 their fore feet (in proportion to their size) more dilated, and 

 the penultimate one comparatively smaller — it being almost re- 

 ceived within the preceding (emarginate) articulation ; but in the 

 small P. ciliata from the Madeiras these tarsal joints are on the 

 ordinary type. 



We have thus three Phalerice apparently peculiar to the At- 

 lantic islands, and all of them remarkably distinct inter se, — 

 viz. the P. Clarkii from (St. Vincent of) the Cape de Verdes, 

 the P. picta from (Lanzarote and Fuerteventura of) the Canaries, 

 and the P. ciliata from (Porto Santo of) the Madeiras. And it 

 is curious that from the rocks of the Salvages (midway between 

 the two northern of these groups) I should have lately received, 

 from my friend the Barao do Castello de Paiva, an example of the 

 " var. bimaculata" (if indeed it he a true variety, for I am by no 

 means convinced that it is not specifically distinct) of the Eu- 

 ropean P. cadaverina — a state which appears to be common in 

 Spain and Portugal, — thus giving us a separate exponent for 

 each of these island-clusters ! And further, the P. cadaverina 

 (probably the typical form, as he does not allude to it as the 

 bimaculate "variety") is recorded by M. Morelet from the 

 Azores ! 



The P. Clarkii was taken abundantly in St. Vincent by Mr. 

 Gray and the Rev. Hamlet Clark, sub stercore humane, on the 

 sea-beach at Porto Grande in December 1856, and subsequently 

 in the same spot, during the month of June, " under stones and 

 rubbish," by Mr. Fry.
