Black, with the following yellow markings; two almost united marks over the 

 antennse, broadly rounded above and narrowed there to a blunt point which 

 reaches close to the line on the orbits, a line on the inner orbits, commencing 

 shortly above the eyes and distinctly dilated below, the two not converging 

 above, a line on the outer orbits, commencing in the centre, and running 

 obliquely to the eyes, an elongated oval, oblique mark on the sides of pronotum 

 at the base, the lower side of the mark straight, narrowed and produced, the 

 apex of the pronotum, a transverse mark, narrowed behind, in the centre of the 

 of the niesonotum, a short one, narrowed towards the base, at the sides, close to 

 the tegulffi, postscutelluni, a line on the sides of the apical three-fourths of the 

 metanotuni, narrowed towaids the base and united at the apex to a siniiiai' mark 

 on the apex of the metapleurge, a lougish line on the base of the mesopleura?, 

 rounded above, gradually narrowed on the lowerside; two marks, slightly longer 

 than wide, gradually narrowed at the base, from above downwards, the lower 

 part narrowed to a blunt point, on the sides of the first abdominal segnient, two 

 curved transverse marks, widened on the inner sides, the apical edge irregular 

 and nearly twice the length of the apex of the basal marks on the sides of the 

 second and bands on the base of the following three segments, narrowed in the 

 middle, and becoming successively narrower, the third line being not one-fourth 

 of the length of the first ; a small spot on the sides of the second ventral and two 

 broad lougish lines on the third ; the apex of the clypeus, the mandibles, except 

 at the apex, and the sides and the apex of the pygidium are rufous. Legs black, 

 the tibia; reddish on the onterside, the anterior with a larger yellow line in 

 front; they are covered with long white hair, the calcaria being also white. 

 Wings hyaline, iridescent, the radial and the fore part of the cubital cellules 

 smoky; the uervures and stigma black. 9 . Length 8 mm. 



Head, thorax and base of abdomen thickly covered with long white hair, shin- 

 ing ; the front and vertex strongly and closely, the mesonotuni and scutelluni 

 nearly as strongly, but not so closely, punctured ; the metanotum aciculated, 

 irregularly punctured in the middle; the apical slope almost smooth, more 

 shining than the rest. Propleurse and metapleurse, except above, closely, 

 obliquely and somewhat strongly punctured ; the mesopleurse strongly, but not 

 closely, punctured. Abdomen shining, punctured, weakly at the base, more 

 strongly towards the apex. Pygidium strongly, regularly longitudinally striated. 

 Apex of antennal scape reddish, tinged with yellow; the flagellum reddish- 

 brown below. 



What is doubtless the % is of the same size and is fiom the same locality ; the 

 clypeus, mandibles, except at the apex, the lower half of the inner orbits, a 

 curved mark over the antennse, two broad, curved lines almost touching above 

 on the base of the prothorax, its apex somewhat broadly, a large maik on the 

 apex of the scutellum, transverse at the base, rounded at the apex, postscu- 

 telluni, a broad line on the sides of the apex of the metanotum, broadly dilated 

 below on to the pleurse, base of mesopleurie broadly, a conical mark on the apex 

 below, the apices of the basal six abdominal segments above and marks on the 

 sides of the ventral, bright lemon-yellow. Legs bright lemon-yellow, the coxse, 

 trochanters and base of femora broadly — the postericjr femora less broadly than 

 the others — black. Wings liyaline, the stigma testaceous, the nervures black. 

 Strongly, closely punctured, the metathorax more closely and regulaily than
