t^W LIST ^ ' "^ OF THK ^y SPECIMENS HOMOPTEROUS INSECTS THE COLLECTION BRITISH MUSEUJI. PART IV. PRINTED BY ORDER OF THE TRUSTEES. LONDON, 1862. 82^69 LONDON ; PRINTED BY EDWARD NEWMAN, y, DKVONSHIRE ST., BISHOPSGATE. INTRODUCTION. The principal object of the present Catalogue has been to give a complete list of the specimens of Homopterous Insects contained in the collection of the British Museum, indicating at the same time the peculiarities of each, as regards variation of character, locaHty, and the source from whence it has been derived. With this view, the different individuals of each species contained in the collection are indicated by the letters a. h, c, &c., following the name of the species and its synonymes, and the description, if it appeared to have been before un- described. This part of the Catalogue of Homopterous Insects has been prepared and the new species described by Mr. Francis Walker, so well known for his attention to this order of Insects. JOHN EDWARD GRAY.

The rib-vein slightly approaches the fore border before it re- cedes from it and incloses the brand ; its angle is at three-fourths of the length of the brand, and though very obtuse is more decided than in many other species ; the fourth vein is much curved through- out its length ; its tip only is usually apparent, and is a little nearer to the tip of the rib-vein than to the tip of the third vein ; the third vein springs from the rib-vein, a very little beiore the latter recedes from the fore border, the space between the first and the second forks shorter than the third fork, and much shorter than the third vein before the first fork ; it forms two distinct angles when it emits the forks ; its distance along the rib-vein from the fourth vein, is very nearly twice that from the second ; the tip of the second fork is a very little nearer to the tip of the fourth vein than to the tip of the first fork ; the tip of the first fork is nearer to the tip of the second than to the tip of the third vein, and the latter is a little nearer to the tip of the first fork, than to the tip of the second vein ; the second vein is nearly straight, and diverges slightly from the third, and its distance from the latter at the tip is farther by half than at the base; its distance at the base from the third vein is a little less than that from the first vein at the base, but much less at the tip ; the first vein di- verges considerably from the second, and is almost perpendicular to tlie rib-vein ; its distance on the rib-vein from the second vein is much less than half its distance from the base of the wing, but at the tip it is much more than the above proportion ; the distance between these veins at ihe base is much less than half that at their tips: the legs are long and slender, the hind-legs rather longer than the rest, their shanks slightly curved : there is an appendage on each side of the first joint of the feelers. Var. The second part of the third vein is longer than the first or the second. Var. No second fork in one wing ; in the other wing no first vein ; its second vein is forked, but both the branches cease before they attain the hind border ; the third vein has no fork, and also comes short of the usual lenyth. 942 LIST OF HOMOPTEROUS INSECTS.

The rib-vein is parallel to the fore border till it approaches the latter, and again diverges from it; it encloses no brand, and does not fonn an angle, but is slightly curved outward till it joins the fore border ; the widened part is rather short ; there are no traces of the fourth vein except at its tip, which is nearer to the tip of the third vein than to that of the rib-vein : the third vein springs from the rib-vein a little after the beginning of the widened part ; its length before the first fork is as long as the space between the forks, and a little longer than the second fork ; the distance between the tips of the forks is much more than that between the tip of the LIST OF HOMOPTEROUS INSECTS. 945 second fork and that of the fourth vein, but much less than the space between the tip of the third vein and that of its first fork ; the second vein diverges shghtly from the third vein, and is a little nearer to it at the base than at the tip, and its base is also a little nearer to the third vein than it is to the first ; the distance between the tips of the second and third veins is a little less than the space between the tip of the third, and that of its first fork, and a little more than half the space between tlie first and second veins ; the space between the first and second veins at the base is a little more than half of that between them at the tips. a — r.

The rib-vein is very slender, and nearly parallel to the fore border of the wing, to which its approach and divergence afterwards is very slight; there is no brand, but the vein forms a distiuct though slight angle, and the space which it here encloses is rather short and broad ; there is generally no fourth vein ; the length of the third vein before the first fork is shorter than the space between the forks, but longer than the second fork ; it is rather thick and quite dis- tinct at its base ; the distance between the tips of the forks is about half that between the tip of the third vein and that of its second fork ; the second vein is straight, it diverges from the third, and the distance between them at their tips is nearly twice that at the base ; the dis- tance between the tip of the second vein and that of the third vein is about equal to that between the latter and the tip of its first fork ; along the rib-vein the first vein is farther by half from the second than the second is from the third, and its distance from the second at the tip is farther than that at the base by much more than half. In the female there are generally no traces of the fourth vein of the wing, but in some instances it is quite distinct; it springs from the angle of the rib-vein, and is slightly curved throughout its length ; its tip is nearly as far from that of the rib-vein as it is from the tip of the third vein. The dark colour of the oviparous female seems to be owing to the eggs within it, these are three or four in number. In the male there is a coloured space between the rib-vein and the fore border ; the brand is darker towards the base, and the fourth vein is distinct : it is more active than the males of the other PART IV. 3 O 946 LIST or HOMOPTEROUS INSECTS. species, the chest is much developed, and the abdomen is small. In two instances the female has a distinct brand like that of the male. Var. Male. — The third vein is joined by a cross-vein to the second a little before half the distance from the base of the first fork. Var. Male. — The second branch-vein is obsolete for the latter half of its length, and the lower branch of the first fork of the third vein is also forked soon after its source ; these forks diverge much from each other, and pass to the lower border of the wing. Var. Fern. — The second vein is forked near its base, one fork joins the rib-vein, and the other fork joins the base of the third vein. Var. Male. — A little cross-vein communicates between the se- cond and the third veins near their base. Var. Male and Fern. — Third vein before the first fork longer than the space between the forks, and much longer than the second fork. a—u. England. (In Canada Balsam). From Mr. Walker's collec- tion. 16.

Rib-vein approaching the fore border, near the brand beneath it diverges much, and forms an obtuse angle; brand broad, brown, with a colourless spot ; distance between the first and second veins more than twice farther at the tips than at the base ; second and third veins slightly undulating ; third almost twice farther from the second at the tip than at the base, much nearer to the second at the base than the second is to the first: first fork a little nearer to the second fork than to the third vein, generally as near to the third vein as the third is to the second ; no fourth vein. This species, with A.Juylandis and the eight preceding species, forms a genus or group, which is chiefly characterised by the up- rightness of the first vein. a—f. Russia. Presented by F.
