little Notioxenus, its strongly and closely punctured prothorax (the 

 sub-basal line of which is raised, instead of impressed, and not much 

 curved), added to the convex interstices, deeply- crenate striae, and 

 the numerous small and bright rufo-testaceous patches of its elytra, 

 will at once abundantly distinguish it. Like the last species, a single 

 specimen only was captured by Mr. Bewicke.

Genus Longitakstjs, 

 Latreille, Fam. Nat. des Ins. 405 (1825). 



12. Longitarsus Helena;, n. sp. 



L. oblongo-ovatus, subnitidus, obscure viridescenti-feueus, akitaceus ; 

 prothorace parce et leviter punctate, ante medium latiusciilo, postice 

 paulo angustiore, angiilis posticis obtusis ; elytris sat profuude punc- 

 tatis ; antennis pedibusque longissimis, rufo-testaceis, illis versus apicem 

 femoribusque posticis paulo obscurioribus. 



Mas, tarsis anterioribus articulo basilar! valde elongate dilatato [secimdo 

 latiore].

The greenish-brassy alutaceous surface and pale elongate limbs 

 of this little Longitarsus, in conjunction with the broad, largely- 

 developed basal joint of its four anterior male feet, wHl suiRciently 

 characterize it. A single specimen only was taken by Mr. Bewicke. 

 It is quite distinct from any species with which I am acquainted ; 

 and Mr. Waterhouse, who has been working lately at the Halticida;, 

 assures me that he knows nothing at all like it.

An insect of a veiy wide geographical range, — being recorded from 

 Senegal, the Cape of Good Hope, CafFraria, Madagascar, the islands 

 of Bourbon and Mauritius, the East Indies, and Java. It is a most 

 variable species ; and whatever doubt may be entertained as to the 

 claim for separation of some of the extreme states which have been 

 ascribed to it, there can at least be no question about the St. Helena
