STAPHYLINID.E. 509 



A single example of this Sunius, which was captured by Mr. M. 

 Park in the south of Madeira proper, is all that I have yet seen of 

 the species. In outline and sculpture it is very closely allied to the 

 angustatus ; but (so far as I can judge from the evidence afforded 

 by a solitary individual) it appears to be a little larger and less 

 pubescent ; its head and antennae are a trifle longer, with the eyes 

 just appreciably more oval and less prominent; and its colour is 

 altogether paler, the elytra (which are likewise a little more deve- 

 loped) being apparently almost concolorous, and of a lurid brownish- 

 testaceous hue. Still, since the type from which my diagnosis was 

 compiled may perhaps be scarcely mature, it is evident that further 

 material must be obtained before at any rate its peculiarities of 

 coloration can be regarded as sufficiently determined.

The European S. anyustatus is rather common in the Madeiran 

 archipelago, where it occurs beneath stones and rubbish principally 

 at intermediate elevations. I have captured it in Madeira proper, 

 Porto Santo, and on the southern Deserta ; so that we may be almost 

 sure that it is universal throughout the Group. But it has not yet 

 been observed in the Canaries, 



1406. Sunius bimaculatus. 



Sunius bimaculatus, Erich., Gen. et Spec. Staph. 641 (1839). 



, WolL, Ins. Mad, 594 (1854). 



, Id., Cat. Mad. Col. 195 (1857). 



Habitat Maderenses (Mad.), in salinis inferioribus rarissimus. 



Found sparingly at the lowest elevations in Madeira proper, behind 

 the sea-beach, having been detected hitherto only in saline spots 

 at the Praia Formosa, near Funchal. It appears to be conspecific 

 with Erichson's S. bimaculatus from Sardinia (and probably also 

 from other parts of the Mediterranean district) ; and although the 

 black patch on the disk of each of its elytra is usually well defined, 

 examples sometimes occur (especially when immature) which are 

 altogether pale.
