ON THE COLEOPTEEA OF THE HADEAMATJT. 285 



The Linnean description applies better to this than to the 

 allied Asiatic species ; and Fabricius correctly separated the 

 latter (from China) in bis ' Mantissa ' and ' Ent. Syst.' by the 

 shorter setse, though he gives Tranquebar as the locality o£ 

 2f. rubra, and quotes a figure of Stoll's representing the Asiatic 

 species. But in his ' Syst. Ehyng.' he gives JST. grossa as an 

 African species, and alters the descriptions of both grossa and 

 rubra to correspond, thus reversing the names, in which Stal and 

 other recent authors have carelessly followed him.

This small collection of Coleoptera includes little more than 

 fifty species, and must represent but a very small proportion of 

 the wbole Coleopterous fauna of South Arabia. Of the species 

 from the Hadramaut enumerated in the following list, some have 

 already been recorded from the district of Yemen and other parts 

 of Arabia ; most of the remaining species are identical with, or 

 closely allied to, forms occurring in Egypt, Nubia, and Abyssinia. 

 A few have hitherto been known only from Persia and North- 

 West India ; while a few more have a range extending from 

 Arabia to Senegal in "West Africa. So far as the evidence, as a 

 whole, of such a small collection can be of value, it seems to 

 point to South Arabia as forming part of the Mediterranean 

 subregion, with a slight admixture in its fauna of the Ethiopian 

 element.
