CANARIAN COLEOrTEKA. 71 



ad basin ipsissimam podibusqiie rufo-piceis. — Long. corp. lin. 



2-2i. 



Bembidium concolor, Brulle, in Webb et Berth. (Col.) 58 (1838). 

 Habitat (ut credo) insulas omnes Canarienses, certe in Lanzarota, 

 Canaria, Teneriffa, Gomera, Palma et Hierro, — snb lapidibus per 

 margines aqnarum (vel stagnantium vel fluentium) necnon ad rupes 

 aquosas, hand infrequens. 



This interesting Bembidium, so remarkable as a LopJia for its 

 immaculate elytra*, is in all probability universal throughout the 

 archipelago ; for although it has not hitherto been observed in Fuer- 

 teventura, there can be no doubt that it must exist in that island 

 likewise. I have captured it in Lanzarote, Grand Canary, Teneriffe, 

 Palma, and Hierro (in the first of which it was taken also by Mr. 

 Gray) ; and it was met with by Dr. Crotch at Hermigua, in Gomera. 



109. Bembidium subcallosum, n, sp, 



B. atrum (vix subcyanescens) ; prothorace cordate, angulis posticis 

 subrectis, basi grosse punctate; elytris subparallelo-oblongis, grosse 

 marginatis, maculis duabus testaceis utrinque ornatis, antice stri- 

 ato-punctatis, pone basin profunde transversim imj)ressis ; antennis 

 ad basin ipsissimam pedibusque piceis, tibiis interdum paulo diluti- 

 oribus. — Long. corp. lin. l|-2. 



Bembidium 4-guttatum, Brulle [nee Fab.l, in Webb et Berth. (Col.) 

 58 (1838). 



Habitat insulas omnes Canarienses, Lanzarota et Fuertevcntura 

 (nisi fallor) solis exceptis, in humidis necnon per margines rivulorum 

 vulgare. 



Closely allied to the European B. caUosum ; from which however 

 it dififers in its larger size, altogether broader outline, and darker 

 (almost unmetallic) surface ; in its prothorax being rather more 

 densely and coarsely punctured along the base ; in its elytra being a 

 trifle more oblong (or less dhlong-ovate), with the j^atch on the an- 

 terior disk of each both shorter and less marginal (and therefore very 

 much more widely separated from the anterior one) ; and in its legs 



* M. Brulle, in his short notice (I cannot call it " description") of tliis insect, 

 remarks that it is " distinct du '^-guttattim par I'absence de taches sin* les elytres 

 etfar la presence de deux joints enfonces sur chacun de ces deux organes.'" The 

 two discal impressions to which he refers exist in all the allied species (A.-gutfa- 

 tum, callosum, subcallosum, Schmidtii, &c.), only they happen, from its superior 

 size, to be a little more evident in the B. concolor. He then speaks of the femora 

 only as rufeseent (" avec les ciiisses d'un roux fauve"); whereas the entire legs 

 are invariably of that colour. It is most unfortunate that in such a well-defined, 

 and indeed almost anomalous, species he coidd not call attention to so few <is 

 even four of its numerous characteristics without being absoliitely incorrect in 

 two of them.
