elliptic than the B. rufohrunneus (its jjygidium l)eing less 

 perpendicularly dccurvc'd), with its head less evidently keeled, 

 its antenna? shorter and more compact, its ])rothorax rather 

 more deeply punctured, and with its elj'tra not only of a redder 

 tint and more conspicuously marked, but also very much more 

 finely and lightly striated, and considerably flatter in the in- 

 terstices. The terminal spines of its two hinder tibiae also are 

 less developed, and its hinder femora are entirely free from all 

 traces of the two small denticles which characterize its ally.

A single example of this distinct Longitarsus was taken in 

 St, Helena by Mr. Bewicke, in 1860 ; and two more have 

 lately been communicated by Mr. Melliss. It may easily be 

 known by its alutaceous surface and brassy -green hue, by its 

 pale elongated limbs, and by the largely developed joint of the 

 four anterior feet of the male. Its head appears to be quite 

 unpunctured, and its prothorax sparingly sprinkled with punc- 

 tules which are extremely minute, whilst its elytra are rather 

 strongly punctate *. 



• Whether any Cryptocephalus or Clythra occurs in St. Helena I can- 

 not say ; but I may call attention, in this part of mv catalogue, to the 

 Cryptocephalm ruJicoUis of Fabricius, which was originally described by 

 him (Syst. Ent. 109) in 1775 from a St.-Helena specimen (or .«pecimens) 

 in the collection of Sir Joseph Banks. Judging from his own publications, 

 he seems to have fallen into some unaccountable mistake (or even mis- 

 representation) regarding this species, which he had himself first defined, 

 and ultimately to have shifted his diagnosis to a Mediterranean insect 

 which in all probability is totally distinct from the St.-Helena one; for, 

 in 1792 (nV/<' Ent. Sy.st. i. ii. 61), he added to his original description, and 

 gave as the habitat not only St. Helena, but (on the authority of Prof. 

 Helwig) Italy ! ! In 1798 (vide Suppl. 114, of the Ent. Syst.j he appears
