INSECTA MADERENSIA. 59 



smaller size, and by the more ornamented, prettily painted surfaces of the species 

 which compose it, by the more acuminated terminal joint of theu' palpi, and by 

 the central tooth of their mentum being always obsolete, — whilst from the latter 

 and Bradycellus, to which in general aspect it is far more intimately related, it 

 differs in the simple emargination of its mentum, in its ligula being straightly 

 truncated at the apex, and in having the whole /o?/r anterior tarsi, as in Harpalus, 

 dilated in its male sex. The StenolopU are insects eminently peculiar to damp 

 localities, residing for the most part amongst wet moss, and beneath stones, at the 

 edges of ponds and streams, or burrowing into the loose mud at the roots of rushes 

 and grass in marshy spots, — thus in then- habits (as well as in then- structure) 

 making an evident step towards the coming genera, which are more and more 

 subaquatic as we approach the BemUdiades, and, through them, the truly 

 Hydi'adephagous groups.

Habitat sub lapidibus per litora rivulorum atque in locis bumidis Maderse, sat frequens : in convallibus 

 supra Fuucbal autumno abundat, necnon in Madera boreali, ad Sanctam Annam, mense Maio 

 observavi. 



S. oblong, black, sbining. Prothorax, above and below, bright rufous ; quadrate ; with a faint dorsal 

 channel ; and with a very obscure impunctate fovea on either side at the base. Elytra rufous 

 (being usually however a little paler than the prothorax), and with a large hinder patch, common 

 to both, and covering nearly two-thirds of their entire surface, dark bluish-black ; deeply striated, 

 the strise being impunctate. Legs, palpi and base of antenruB i-ufo-testaceous. 



By no means an unconunon insect both in the north and south of Madeira, 

 between the limits of from 1000 to about 3000 feet above the sea, occurring be- 

 neath stones in moist spots and at the edges of the streams. At the Curral das 

 Romeii'as, and in the other ravines above Funchal, I have taken it in tolerable 

 abundance during the autumnal months, and in equal profusion, at the end of 

 May, on the damp ledges of the perpendicular rocks towards the upper extremity 

 of the Piibeiro de Santa Luzia ; as also, about the middle of May, on the northern 

 side of the island, at Santa Anna. It is found in nearly all parts of Eui'ope, and 

 is recorded in Algeria and the Canary Islands.
