It appears to inhabit both the northern and southern extremities of Brazil; for I have seen it in a box sent from Para, and my specimens were captured in Minas Geraes by my friend Dr. Langsdorff. It is, however, a rare species; for I have only seen seven or eight specimens, and they were all males: the female, when found, will probably differ as remarkably as in most of this genus. The opaque spot on the inferior wings above is very large; but the tuft of hair corresponding beneath the superior wings, is entirely wanting. It should be likewise observed, that although this insect in every outward respect resembles a genuine _Colias_ (the type of which may be _C. Ebule_), it differs very materially in the terminal appendages of the abdomen; the last joint being the shortest, and scarcely pointed; and the hook, instead of being concealed beneath this segment, is exserted beyond it, and met by two others, one at the base of each lateral valve: these valves are also much shorter, ovate, and not attenuated, although ending in an incurved hook. In the present ignorance in which a true knowledge of the Lepidoptera is involved, it is impossible to say how far these dissimilarities may point out natural groups; it is therefore of the highest importance to the science such facts should be noticed. * * * * * Pl. 7 [Illustration] CARDUELIS cucullata. _Hooded Seed-eater._ * * * * * GENERIC CHARACTER. _Rostrum breve, validum, conicum, rectissimum; mandibulis subaequalibus; apice immarginato, recto, acuto; mandibula superiore culmine convexa; inferiore basi marginis angulata, utrinque subtusque convexa._ Typus Genericus _Fringilla Canaria_.

Bill short, stout, very conic, without any curvature above; both mandibles nearly equal, the tip entire, straight and sharp; upper mandible convex above: lower one at the base of the margin with an obtuse angle, the sides and under part convex.

The only one I have yet seen is in the possession of E. Falkner, Esq. of Fairfield near Liverpool, who received it with a few other rare birds from the Spanish Main.
