That the male is the Apis Brasilianorum of Linnasus I 

 have no doubt whatever ; it in every respect agrees with 

 the description in the " Systema Natura," which is fortu- 

 nately more ample than is usual in the descriptions of the 

 species of the genus Apis. Lansdowne Guilding referred 

 the insect to the Linnean species, with a doubt ; but after 

 an examination of a large number of fulvous-coloured 

 males of different species of the genus, I feel satisfied of 

 this being the Linnean one. The female I do not think 

 can be the X. morio of Fabricius, who describes the wings 

 as " Alls cyaneis ; " he also adds in " Mus. Dom. Banks," 

 the specimen must have been lost in some Avay, as it was 

 not in that collection when it came into the possession of 

 the British Museum. The female of X. Brasilianorum 

 has the wings, as described by Prof. Westwood, of " a 

 brassy hue with purple reflections;" it is broad, black, 

 shining, and has the head almost as wide as the thorax ; 

 the abdomen fringed with black pubescence ; the thorax is 

 rounded posteriorly, as is the case in all the South Ameri- 

 can species that I have seen. Length thirteen lines. The 

 male is of a fulvous-yellow ; the clypeus, and front of the 

 scape of the antennae, more or less yellow ; the apical mar-
