chandise, is of course totally unconnected with the true fauna 

 of the island. It has been established equally in the Madeiran, 

 Canarian, and Cape Verde groups. 



Genus 13. Attagenus. 

 Latreille, Hist. Nat. iii. 121 (1802). 



15. Attagenus gloriosce^. 



Anthrenm Gloriosm, Fab., Syst. Eleu. i. 107 (1801). 

 JEthriostoma glorioscB, Motsc'h., Etud. Ent. 146 (1858). 

 Attagenus Gloi-iosce, Woll., Ann, Nat. Hist. vii. 301 (1861). 



Of this prettily fasciated Attagenus — which has acquired, 

 through the medium of commerce, an almost cosmopolitan 

 range — two examples, now before me, were captm^ed by Mr. 

 Melliss at St. Helena. The species has established itself like- 

 wise in the island of Ascension — where it was taken, during 

 April 1860, by the late Mr. Bewicke ; and it is reported also 

 from India, Eastern Africa, and America. 



Fam. 7. Histeridae. 



Genus 14. Teibalus. 



Erichson, in Klug, Jahrb. i. 164 (1834). 



16. Trihalus A-striatus, n. sp. 



T. rotundato-ovalis, piceo-niger, nitidus, iibique (in disco levins) 

 punctatus ; fronte minntius punctulata, subsemicirculari, angulis 

 anticis subrectis, ocaHs parvis, simplici (nee transversim cari- 

 nata) ; elytrorum striis 4 dorsalibus sat profundis, punctatis, 

 usque ad medium ductis, suturali nulla sed ad basim ipsam bre- 

 viter arcuatim conspicua, humerali tenid obliqua ; pygidio per- 

 pendicular! ; antennis pedibusque piceis ; tibiis anticis leviter 

 circa 5- vel 6-denticuIatis. 



Long. Corp. lin. vis. 1|. 



The rather small size and entirely punctulated surface of 

 this little Histerid, combined with its semicircular wwcarinated 

 forehead, and the fact of its elytra being totally free from a 

 sutural stria (which is only traceable as a very short subscu- 

 tellar arcuated impression), affiliate it with the small group 

 of species which constitute the genus Trihalus ; but it seems 

 to differ {inter alia) from the whole of them in having four 

 very distinct dorsal punctured strise continued to about the 

 middle of each elytron. Apart from other characters, its 

 piceous-black hue, subrufescent limbs, and perpendicular py- 

 gidium will serve additionally to distinguish it. The single 

 example from which the above diagnosis has been compiled
