Both the birds are represented the size of life, and may be included in one description: the upper plumage obscure blueish green, glossed with a coppery or golden tinge and shaded with brown, the plumage beneath entirely grey; ears and sides of the neck the same, the latter with some spots of greenish. Tail large, even, and broad; the two middle feathers green, tipt (in the male) with blackish; the next pair black, with the base green, and the extreme points whitish; the remainder black, with their ends more or less white. Wings violet brown, the shafts of the three outer quills, in the male, dilated and compressed, but simple in the female. Said to inhabit Cayenne. Although the bill of this species is all but straight, it belongs naturally to the curved-bill division. * * * * * Pl. 132 [Illustration] MACROGLOSSUM annulosum, _Upper figure_ * * * * * GENERIC CHARACTER.--See Pl. 64. * * * * * SPECIFIC CHARACTER. _M. alis nigris, anticis fasciis 2 hyaline maculatis ornatis; abdominis nigri, segmento tertio niveo._ Wings black, anterior with two bands of hyaline spots; abdomen black, the third segment snowy. * * * * * An elegant insect; so closely allied to _Sphinx Tantalus, Lin._ (_Drury_, _v._ 1. _pl._ 26. _f._ 5.) as to excite a doubt if it should be considered as a separate species. Drury's figure and description, however, of that insect, induce me to think they are most probably distinct. _S. Tantalus_ is without the two bands of hyaline spots, and is much smaller in size. In this insect are three small, white, snowy dots, on the sides of the lower segments of the abdomen, and the same beneath: the anal segment is grey; with the margin, and spot in the middle, black. Inhabits Brazil, but is a rare insect. * * * * * MACROGLOSSUM fasciatum, _Lower figure._ * * * * * _M. alis nigricantibus, anticis fusco variis, posticis striga aurantiaca centrali ornatis; thorace grisea; corporis lateribus, maculis aurantiacis, nigris et pallide fulvis insignibus; antennis gracilibus; unco producto._ Wings blackish, anterior variegated with brown, posterior with a central orange stripe; thorax grey, sides of the body with orange, black, and pale yellow spots; antennae slender, hook lengthened.
