CANAKIAN COLEOPTERA.

stria is said to be scarcely visible at the base." It is apparently 

 very rare, the only three specimens which I have seen having been 

 captured by myself, beneath cast-np sea-weed, on the sandy shores 

 of the curious salt-water lake known as " Januvio,'' towards the 

 south-western extremity of Lanzarote, — during my visit to that re- 

 markable spot, in company with the Rev. R. T. Lowe, on the 26th 

 of March 1859. I may add that, as has been so often observed in 

 the Dyschiril of more northern latitudes, it was, even in that remote 

 locality, associated mth a Bledius, — a noble species somewhat akin 

 to the European bicomis, and which I shall hope to describe under 

 the name of B. Januvianus. 



12. Dyschirius suhaeneus, n. sp. 



D. seneo- (vel subpiceo-) niger, clypeo simplici ; elytris ovato-ob- 

 longis, profunde punctato-striatis, punctis postice evanescentibus ; 

 antennis pedibusque rufo-piceis ; tibiis anticis extus breviter den- 

 ticulatis. — Long, corp. lin. l|^-lg. 



Habitat in Canaria Grandi, per litora paludis lutosas (nee salinsB) 

 ad Arguiniguin d. 14. Ap. a.d. 1858 deprehensus. 



The present Dyschirius has very much the size and general aspect 

 of the common European Z>. ameus, with wliich indeed before exami- 

 nation I had regarded it as coincident, A more careful inspection, 

 however, has brought to light several small differential features, 

 which it is the opinion of Dr. Schaum must separate it specifically 

 from that insect, "It is distinct," says he, "from the ceneus (to 

 which it is closely allied) by the first and second striae commencing 

 in a deep point at the base, by the first stria being much deeper, and 

 by the stronger teeth of its anterior tibiae. It belongs to my Section 

 B. 2. (j. aa. (p. 201)." I captured thirteen examples of it by brush- 

 ing the fine grass along the muddy edges of the freshwater lake at 

 Arguiniguin, in the south of Grand Canary, during my visit there, with 

 the Rev. R. T, Lowe, on the 14th of April 1858. 



13. Dyschirius pauxillus, n. sp. 



D. aeneo-niger, clypeo simplici ; elytris subovato-oblongis, profunde 

 punctato-striatis, punctis postice evanescentibus ; antennis pedi- 

 busque rufo-piceis ; tibiis anticis extus vix denticulatis. — Long.

Habitat Teneriffam ; duo specimina (per aerem volitantia) prope 

 " Puerto Orotava," mense Maio a.d. 1858, cepi. 



The smaller size of this little Di/schirius, combined with its fore 

 tibite being almost unarmed along their outer edge, will suffice to
