Shining, punctate, black and profu.sely marked with flavous. Head 

 short, tran.sverse, closely and coarsely punctate, and narrowed behind the 

 eyes ; internal and external orbits, labrum and centre of mandibles, some- 

 times also two longitudinal lines and two dots on the face, or whole face 

 except often a longitudinal black line, flavous. Antennae very rarely with 

 the scape white-marked beneath ; the fourth and following antennal joints 

 ferrugineous beneath. Thorax distinctly, coarsely and somewhat sparsely 

 punctate, a little shining ; a mark before the radix and on the disc, 

 usually also a more or less cordiform mark or transverse line before the 

 petiole, a dot beneath the radix, another or a perpendicular line on the 

 mesopleurae, the prothorax and sometimes a dot on the mctapleurac, fla- 

 vous ; metathorax convex with the upper areae entirely wanting, but the 

 petiolar distinct and complete ; spiracles large and elongate. Scutellum 

 and postscutellum flavous. Abdomen smooth and nitidulous with the 

 three or four basal segments longer than broad and broadly margined with 

 flavous ; third of $ sometimes immaculate ; terebra \er}- slightly longer 

 than the abdomen and distinctly reflexed. Legs slender, red ; the anterior 

 coxae flavous, of ^ partly, the front ones of 9 above, black ; anterior 

 trochanters flavous, of t^ partly, of 9 above, black ; femora of 9 fulvi- 

 dous, of (J paler with the anterior flavous beneath ; hind femora nearly 

 entirely black ; tibiae fulvous with the hind ones jipically darker, anterior 

 of (5 entirely or beneath flavous ; tarsi concolorous. Wings hyaline with 

 their apices very distinctly darker; stigma and radius infuscate; radix and 

 tegulae flavous, the latter rarely infuscate ; areolet nearly regular, elon- 

 gately petiolate; nervellus oblique and intercepting below the centre. 

 Length, 9 — 10 mm. 



Holmgren considers the form with black hind femora in both sexes a 

 variety, but it is certainly the commonest with us ; he says the 9 some- 

 times has the clypeus fuhous with the thorax and hind femora entirely 

 black and the second and third segments alone apicall\- stramineous ; or 

 with face, thorax and scutellum innnaculatt-, and the three basal segments 

 apically castaneous. In fact the llavidous markings vary within certain 

 limits to a considerable extent, but the species may always be at once 

 known from all others o{ Lissono/idcs by the very determinatelv infumate 

 apices of all the wings.
