commits those dreadful ravages so often recorded to have occurred in Abyssinia: and I can also add that, while I resided at Bombay, numbers of the same species of locusts were sent down to Mr. Duncan from the upper country for the purpose of pointing out the insect which had at that time laid waste several extensive tracts of land in the interior.
The head and shoulders of this insect are armed with a thick shell or case; that of the head has a leaden grey colour when alive, interspersed with red; the shoulder plate being of a reddish brown, spotted with white, smooth in front, and rough on the hinder part. The eye is bright yellow, with three black bars across it; feelers or horns black; the wings are of a yellowish brown, lower part tinged with a fine purple, and the whole obscurely dotted with black. The legs are externally of a leaden grey colour, the upper part shading off into black; the ribs also deep black, inside of second joint bright purple, and the thorns scarlet tipped with black; the extremities being formed of triangular shells formed of two sharp claws and a knob in the centre smooth and round. The body is cased with seven strong plates on the back, folding over one another, and the same number of a softer consistency covers the belly. It has four small feelers depending from the sides of the mouth, the two foremost of which have five joints and the hinder three. An immense flight of these insects came over to one of the Amphila islands while we remained in English Harbour, for an account of which see this work.
LIST OF NEW AND RARE PLANTS,
COLLECTED IN ABYSSINIA DURING THE YEARS 1805 and 1810.
Arranged according to the Linnæan system.
The plants having Br. MSS. annexed form new genera, described in the manuscripts of Mr. Brown. To this gentleman's kindness I am indebted for the list, which he made out from a collection of dried specimens brought by me into the country, and now in the possession of Sir Joseph Banks. The names without reference are considered by Mr. Brown as applying to new species; and for the few that have been published already, contracted references are given to the works in which they occur, namely, Willdenow's Species Plantarum; Forskal's Flora Ægyptiaco-Arabica; Vahl's Symbolæ Botanicæ; and the Appendix to the Travels of Mr. Bruce.
