Plesia spiloiiola sp. nov. 



Black ; a narrow line on tlie inner orbits, commencing opposite the autenufe 

 and continued shortly beyond the eyes, a large band on the sides of the pre notnm 

 above the basal slope, roundly narrowed behind, transverse in front, a large mark 

 in the middle of the mesonotum, its base roundly incised, its sides straight, 

 oblique, narrowed towards the apex, a broad line opposite the tegulse, postscutel- 

 lum, a mark on the centre of the basal half of the metanotum, the base slightly 

 projecting in the middle behind, gradually, roundly narrowed, the apex pro- 

 duced into a narrow point, half the length of the dilated base, a broad line on 

 the apical three-fourths of the sides, its outerside straight, the inner rounded, 

 gradually narrowed towards the top, from near the apicnl pa it another line runs 

 obliquely upwards to shortly above its middle; this part becomes gradually 

 obliquely narrowed towards the top; the lower i)art of both is broadly, roundly 

 incised; a large broad line on the base of the mesopleurae. extending below the 

 middle, the top bluntly rounded above; from there it becomes gradually widened 

 to a blunt point, from which it becomes gradually narrowed below, this lower 

 narrowed part being longer than the upper, two large irregular marks, dilated on 

 the innerside at the base, two large marks on the sides of the second segment, 

 occupying the basal two-thirds, roundly narrowed on the innerside and united 

 at the base by a straight line, a line on the basal half of the third, with a broad, 

 shallow incision in the middle and similar bands on the following two segments, 

 less deeply incised in the middle, a longitudinal line on the second ventral and 

 broad transverse lines on the sides of the following two segments, bright lemon- 

 yellow. Legs black, a large yellow mark on the base of the hinder coxae: the 

 tarsi are for the greater part rufous. Wings almost hyaline, the radial and cubi- 

 tal cellules smoky, the nervures and stigma black. J • Length 16 mm. 



Head, prothorax and mesothorax, base, sides and ventral surface of abdomen 

 and the legs covered, but not thickly, with long white hair, the tarsal spines 

 tinged with rufous; the calcana white. Apex of clypeus fringed with short red 

 hair. Head closely and strongly punctured, the face and clypeus less strongly 

 than the rest. Pronotum strongly, coarsely punctured ; the propleurse closely, 

 uniformly, strongly obliquely striated ; the base and apical two-thirds of the 

 middle lobe of the meson(jtum smooth; the base of the latter, the lateial lobes, 

 except at the base and the scutellum, except in the centre at the base, strongly, 

 but not closely punctured. Postscutellum smooth. Metanotum strongly acicu- 

 lated. the apex sparsely punctured. Mesopleurse strongly punctured. Meta- 

 pleurje, except at the base, closely obliquely striated. Basal three abdominal seg- 

 ments smooth in the middle, the sides sparsely punctured ; the apical are more 

 strongly punctured all over; the pygidium closely strongly striated, except round 

 the edges, which are rufous. The basal abscissa of the radius is slightly longer 

 than the others, which are almost equal in length ; the first recurrent nervure is 

 received shortly beyond, the second shortly behind the middle.
