markings of the upper surface (these not always being symmetrical 

 on the elytra), according to the predominance of the light or dark 

 colour, some of the spots on the prothorax or elytra being often 

 absent, especially in the female. The median sulcus on the first 

 central segment also varies a little in length, and the tooth at the 

 outer apical angle of the elytra is sometimes obsolete. The coloration 

 of the under surface is similar in both sexes. 



The Algerian insect, M. Oberthtir informs me, has the 

 interocular portion of the head relatively narrower ; the 

 longitudinal impression upon the first ventral segment 

 deep, sharply defined, and extending to the posterior 

 margin of the latter ; the fifth ventral segment of the male 

 narrowly and somewhat deeply emarginate in the middle ; 

 the tooth at the outer apical angle of the elytra (in the 

 male) obsolete ; and the anterior margin of the prothorax 

 less sinuate. In the coloured drawing before me of the 

 type of the male (margaripicta) the second elytral fascia is 

 represented by a large subtriangular patch on each elytron, 

 this being more extended in the longitudinal direction than 

 in any of the Spanish specimens obtained at Albarracin. 

 The single male from Gibraltar has a narrow streak 

 extending down the fifth elytral interstice from the first 

 yellow fascia, and in one of the examples of the same sex 

 from Albarracin this yellow streak runs still further down 

 and joins the second fascia, so as to completely enclose a 

 common transverse nigro-violaceous patch. 



In the simple anterior tibise in the male, the present 

 species, as noted by Marseul (under B. margaripicta), 

 differs from all the other European forms, three of which 

 occurred in the pine-forests of the same district in Spain, 

 approaching the genus Eurytliyrca in this respect, in which, 

 however, the scutellum is much larger, etc. The sexual 

 dimorphism and the similar form of the anterior tibiae in 

 the two sexes tend to show that the insect will probably 

 have to be removed from the genus Buprestis. 



It may be observed also that the habits of B. sanguinea 

 are different from those of its congeners, these latter 

 attacking pine-logs, upon which the beetles may frequently 

 be seen during the heat of the da} 7 . 



B. hilaris, Klug (= variegata, Klug), from Egypt, said 

 to be found on mint, is perhaps congeneric with B. 

 sanguinea. B. amori, Graells, from Spain, is sunk by 

 Marseul and others as synonymous with the Algerian
