A U-shaped mark on mesoiiottiin, alar iiervnrns l)lack ; the second cubital 

 cellule narrowed in front, ocellus in a large depression with obliquely 

 sloped sides, the furrow above it narrow; breast with two large black 

 marks, the narrowed apical part of the black band on the basal abdo- 

 minal segment narrowed to a point at the apex. ■ • NpeciOMa Cress. 



Two yellow lines on mesonotum, not united at the apex, the alar nervures 

 fulvous; the second cubital cellule not narrowed in front; square, 

 ocellus not in a large depression, the upper furrow wide, deep, breast 

 immaculate, the apex of the black mark on first abdominal segment 

 not narrowed, its sides projecting outwardly deiiTf reiisis. 



Monedula speciosa Cress. 



Black; the clypeus, labrum, mandibles except at the apex, a narrow line on 

 the outer orbits, the face except for two oblique lines on the top, extending to the 

 middle, these lines being roundly nariowed on the innerside at the base and 

 rounded at the apex, the prothorax except broadly at the base and for a lateral 

 line, roundly narrowed above, a short line at the tegulse, an interrupted broad 

 line on the scutellum, a narrow curved line on the postscutellum, an irregular, 

 narrow, more or less interrupted, line round the apex of metanotum, a large 

 broad mark, covering the mesopleurse, exce])t for a triangular mark in the centre 

 of the apex below, a narrow line on the apex above and a line round the poste- 

 rior part of the tubercles, the breasts, the metapleurse except the base and a broad 

 line behind and below the spiracles, the yellow at the apex extending irregularly 

 on to the metanotum, a large mark, roundly narrowed on the innerside, on the 

 sides of the first abdominal segment, a larger mark, not narrowed, on the second, 

 a narrower, shorter one on the third ; a shorter, slightly broader one on the 

 fourth and fifth, an irregular spot, one-third the length of that on the fifth, on 

 the sixth, the apical third of the seventh, two separated transverse marks on 

 the centre of the second and third, two united ones on the fourth and fifth, a 

 triangular one on the sixth, the greater part of the first ventral, an irregular 

 large bisinuated mark along the sides of the second, the apex prolonged to near 

 the centre, a triangular mark on the sides of the third, an irregular mark on the 

 fourth and a smaller regular one of equal width on the sixth, yellow. Legs 

 yellow, the femora with a broad black line above; the apical joint of the four 

 anterior tarsi and the apical four of the hinder, black. Wings hyaline, the nerv- 

 ures black. % . Length 23 mm. 



On the middle femora there is a basal spine, followed by three larger ones, of 

 which the middle is the stouter and longer and it is bifid at the apex ; following 

 these are three shorter, thinner teeth, which become successively shorter. The 

 basal three joints of the fore tarsi are of equal width ; the fourth is .shoiter and 

 dilated on the innerside; the last is as long as the preceding three united, is 

 greatly dilated, becoming gradually widened from the base to the apex, which is 

 almost transverse; the inner claw is roundly dilated on the inner basal half. 

 Basal half of pygidium punctured closely and strongly, the apex smooth ; the 

 segment is broad at the base and becomes gradually roundly narrowed to a blunt, 

 rounded point. The apical half of the central spine of the armature is white. 



The flagellum of antennae is entirely black ; the scape clear yellow. Tibiae dis- 

 tinctly spinose ; the spine on the apex of the middle is brown, stout. Basal joint 

 of middle tarsi broadly, roundly incised; at the base of the incision are three 

 long, stout spines, the apical the larger. There is a narrow, not deep, incision at
