coarser and more decidedly crenate, and with their postmedial fascia 

 a trifle more dentate and developed. 



Dromius strigifrons, n. sp. 



D. elongatus, parum nitidus ; capite prothoraceque rufo-ferrugineis, 

 illo sat magno subrotundato in fronte grosse longitudinaliter stri- 

 goso, hoc anguste subcordato ; elytris elongato-ovatis, ad humeros 

 rotundatis declivibus, depressis, profunde striato-punctatis, fusco- 

 testaceis, per suturam anguste necnon in macula minuta communi 

 ante apicem sita nigrescentibus. Long. corp. lin. vix 2|. 



Habitat in lauretis editioribus Gomerse, a DD. Crotch parce lectus. 



Detected by the Messrs. Crotch, under the bark of laurels, at a 

 high elevation in Gomera ; and / believe that they found it likewise 

 in Teneriffe (near Ycod el Alto), but, as the specimens from the latter 

 were unfortunately lost on their homeward route, I have not sufficient 

 evidence to permit me to cite it for that island. 



The D. strigifrons differs from the amoenus (to which it is closely 

 allied) in its rather broader and longitudinally rugose forehead, in its 

 prothorax being a little more narrowed behind (and therefore some- 

 what less straightened at the sides), and in its elytra being more 

 depressed, with their striai much more coarsely punctured, and with 

 the postmedial fascia of that species reduced to a minute central, or 

 sutural, spot (common to both), placed further towards the apex. It 

 is perhaps still more nearly related to the D. insularis (from the 

 sylvan districts of Madeira), with which in its strigulose forehead 

 and general contour it almost agrees. But it is more shining (or less 

 alutaceous), and its elytra have their stria3 more distinctly punctured, 

 with the postmedial dentate fascia which is more or less conspicuous 

 in that insect reduced to a small subapical speck. 



Dromius amcenus. 



D. prajcedenti similis, sed capite vix angustiore (sive minus rotundato), 

 in fronte fere simplici (nee longitudinaliter strigoso) ; prothorace 

 vix magis quadrato (ad latera subrectiore) ; elytris sensim magis 

 convexis leviusque striatis (striis fere simplicibus, nee distincte 

 punctatis) necnon laetius nigro-pictis (sc. per suturam minus an- 

 guste et in fascia postmedia multo majore latiore dentata nigres- 

 centibus). Long. corp. lin. 2^-vix 2J. 



Dromius amoenus, Woll., Cat. Can. Col. 12 (1864). 



Habitat Teneriffam, in lauretis humidis editioribus sub cortice laxo 

 sese occultare delectans.
