Female. Length 4-5^^ lines. — Black, head and thorax covered 

 with confluent punctures, the ch-]ieus more finely punctured and 

 interspersed with large punctures ; above the clypeus the face is 

 covered with cinereous pubescence. Thorax, aline on the collar, 

 another over the tegulje and passing along the base of the scu- 

 tellum, two abbreviated lines on the prothorax, and one passing 

 from the base of the wings round the metathorax over the post- 

 scutellum, of cinereous pubescence ; the legs are variegated with 

 pubescence of the same colour; wings fusco-hyaline, clearest 

 towards their base. Abdomen very finely punctured, at its apex 

 is a semicircular space which is rugose ; the basal segment has its 

 margins traversed by a band of cinereous pubescence, slightly 

 inten-upted in the centre of both the basal and apical margins, 

 the three follomng segments have a similar band on their apical 

 margins : the apical segment has a triangular patch on each side.

This species varies in having the legs entirely red, the antennae 

 also are occasionally red beneath ; these difi'erences occur in the 

 specimens from Mexico, but they cannot be considered sufficient 

 to constitute a distinct species.
