the D. amcenus, seeing that the detection of the strigifrons at the 

 Canaries and the acknowledgment (now for the first time) of the 

 oceanicus at the Madeiras would render it desirable that all these 

 closely allied (but, I believe, truly distinct) species should be accu- 

 rately defined inter se. The D. amcenus has been observed hitherto 

 only in the sylvan districts of Teneriffe, where it occurs under 

 loosened bark at a rather high elevation. 



Dromius umbratus, n. sp. 



D. sigmati aflinis, sed major et in partibus pallidioribus quoque paulo 

 minus testaceus, capite prothoraceque submajoribus latioribus, 

 elytrorum fascia multo majore, crassiore (sc. maxima), rectius 

 transversa, sive minus dentata. Long. corp. lin. 2. 



Habitat in Madera, a Dom. Bewicke parce deprehensus. 



Two examples of this Dromius are in the collection of the late 

 Mr. Bewicke, by whom they were captured in Madeira proper ; but 

 I have no means now of ascertaining their precise locality. They 

 differ from the D. sigma in being considerably larger, and in all the 

 pale portions of their surface being of a rather more rufescent (or 

 less pallid) hue, in their head and prothorax being wider and more 

 developed, and in their elytral fascia being very much thicker and 

 straighter (or less dentate). 



Genus BROSCUS. 

 Panzer, Index Ent. i. 62 (1813). 



Broscus crassimargo, n. sp. 



B. ater; capite prothoraceque nitidis, hoc cordato, ad basin leviter 

 subpunctato, ad latera ipsissima grosse marginato subcyanescente 

 (margine usque ad angulos ipsos posticos conspicue ducto) ; elytris 

 opacis, levissime (tamen distincte) striato-punctatis, ad latera 

 ipsissima angustissime marginatis subconcoloribus (margine etiam 

 usque ad humeros parum crasso et ibidem in angulum sat acutum 

 humeralem abrupte terminate) ; antennis fusco-piceis, concolori- 

 bus (art l mo retiquis vix dilutiore) ; pedibus elongatis, nigro- 

 piceis. Long. corp. lin. 10-11. 



Habitat Gomeram, a DD. Crotch in lauretis humidis editioribus 

 detectus. 



This fine Broscus appears to be a little larger than even the 

 B. glaber, from Grand Canary ; and it may at once be known from 

 both of the Canarian species by its elytra being quite opake and dis- 

 tinctly (though very lightly and minutely) striate-punctulate, by the
