 on the scutellum ffi^nsvcrse Ix'hind, dilated in the middle in 

 front), the tuherclcs, a mark (l)roa<lly extended dowiiwiinls) 

 on the aj)ex, an irregular mark under the hind wing.s, and 

 the apex of the n)edian segment, lemon-yellow, Mesoiiotum 

 closely transversely striated; the scutellum longitudinally 

 striated ; the postscutcUum closely rugose. Median segment 

 closely and strongly transversely striated ; the striae on the 

 central lobe more widely separated than on the sides; in the 

 centre of the basal lobe is a narrow furrow. Propleurae 

 smooth ; niesopleurte closely horizontally striated ; meta- 

 pleurte closely, obliquely, rugosely striated. Wings iri- 

 descent, hyaline, with a aistinct fuscous tint ; the apex with 

 a narrow smoky cloud. Legs black, the femora more or less 

 dark brown in front and below ; the four anterior tibia3 

 yellow in front. Abdomen black; the apex of the basal 

 segment dark brown; the other segments lined with lemon- 

 yellow on the apices. 



The amount of yellow on the abdomen and legs varies. 

 The male wants the two yellow marks on the face, and in the 

 female these may become amalgamated.
