This A\'i(Ielj spread Dermestes having originally been de- 

 scribed by Fabricius (in 1775) from a St.-Helena example, in 

 the collection of Sir Joseph Banks, it seems scarcely right to 

 omit it from the present memoir, even though I do not myself 

 ha])pen to have seen a specimen of it from that island. Being 

 peculiarly liable to transmission, in various articles of mer- 

 chandise and commerce, throughout the civilized world, it has 

 been made to acquire a very extensive geographical range, — 

 being recorded not only in Europe, but even from South 

 America, Mexico, Otaheite, the East Indies, Siberia, Arabia, 

 &c. ; and it Avas obtained abundantly, by the late Mr. Bewicke, 

 at Ascension. Speaking of it, in 1861, in a short paper on 

 Ascension Coleoptera, I remarked that " it belongs to the se- 

 cond of Erichson's sections, in which the third and fourth 

 abdominal segments of the males (instead of the fourth alone) 

 are furnished beneath with a little circular fossette armed with 

 a cone (or convergent fasciculus) of powerful bristles. In 

 specific details, it may be known from its several allies by its 

 (black) upper surface being uniformly and rather densely 

 clothed with a coarse yellowish-cinereous pile, by its rather 

 elongate and slightly narrow outline, and by its abdominal 

 under segments having, each of them, two roundish patches 

 of darker pile in their centre (gradually dimimshing and ap- 

 proximating in each successive segment towards the apex), 

 and a sublunate one at either lateral edge."

An example of this almost cosmopolitan Dermestes (which 

 is so well characterized by the very minute spinule with which 

 the extreme apex of each of its elytra is furnished) was taken 

 by ^Ir. Melliss at St. Helena ; but the species, which (like 

 the I), cadaverimts) is so eminently liable to accidental dis- 

 semination along with various articles of commerce and mer-
