the Australian Longicornia. 545 



greyish-brown, with two pale yellowish discal stripes ; scutellum 

 rather transverse, rounded behind ; elytra broadest at the base, 

 where it is considerably broader than the prothorax, greyish- 

 brown, with several small scattered spots at the base and in a line 

 along the posterior half of the suture on each side, an oblique 

 irregular patch commencing in the middle and continued down- 

 wards and outwards to the margin, and between this and the 

 shoulder a small triangular patch at the side, all of a pale yellow 

 colour ; body beneath and legs with a thick greyish pubescence, 

 speckled with yellowish-brown. 



Length 6 lines. 



A larger and proportionally stouter species than Saperda paulla, 

 Germ,, and otherwise very distinct. 



2. Saperda mystica. 



S. fusca, albo-pilosa; antennis baud annulatis ; prothoracis vittis 

 duabus, elytrorumque notis variis, cinereis. 



New South Wales ? 



Closely covered with a smooth brown pile and with scattered, 

 slender, white hairs ; head brown, nearly unicolorous ; antennae 

 ashy, spotted at the base ; prothorax brown, with two discal, pale 

 ashy stripes, which are connected by a narrow transverse band in 

 the middle ; scutellum rounded posteriorly ; elytra broader than 

 the prothorax at the base, brown, with pale ashy longitudinal 

 patches, which are partially connected along the suture on each 

 side, but not touching it ; another set of uncertain patches, extend- 

 ing from the shoulder to the apex at the side, but breaking up 

 into small spots at the apex, and a very distant zig-zag line 

 obliquely behind the middle, all of the same ashy colour ; body 

 beneath with a dull ochreous pile, varied with greyish ; legs hairy, 

 brown, speckled with ashy. 



Length 6 lines. 



Narrower than the last species, with a smoother pile, and, notwith- 

 standing a considerable difference in colour, closely allied to it. The 

 four Australian species of Saperda differ from the true Saperdce 

 of Europe, in the presence of a tubercle or tooth on each side of 

 the prothorax near its anterior border, and in the elevated pro- 

 sternal process. The antennae also are never so long as the body. 

 Saperda Bohemanni and Saperda erythaca should rather be placed 

 with Phytcecia on account of their bifid claws.
