Abdomen smooth, shining, and very delicately punctured, the 

 apical margins of the segments rufo-piceous ; the third and. fourth 

 with a narrow white pubescent fascia, the third usually interrupted; 

 the apical fimbria fuscous, with a few white hairs at the sides. 



Male. Length 4 lines. — Head : the antennas nearly as long as the 

 thorax ; the flagellum fulvous beneath, and the scape usually with 

 a yellow spot at the apex in front ; the face below the insertion 

 of the antennas and a spot at the base of the . mandibles yellow. 

 Thorax globose, closely punctured, and with a thin pale fulvous 

 pubescence ; on the postscutellum and at the sides of the meta- 

 thorax it is griseous ; on the legs it is griseous, but more or less 

 fulvous on the tarsi, their apical joints being rufo-testaceous ; the 

 anterior femora in front, as well as the tibiae, more or less rufo- 

 testaceous ; the posterior femora incrassate, the tibiae being also 

 swollen and somewhat curved ; the calcaria pale testaceous ; wings

This insect is very rare in this country ; and it is a remarkable fact 

 that up to the present time, 1876, only males have been captured. The 

 first recorded was taken by Dr. Leach in Devonshire ; many years 

 subsequently a second male was taken by Mr. J. Walton in the ISTew 

 Forest ; on the 3rd of July, 1842, Mr. S. Stevens captured the third 

 male at Weybridge ; in 1874 Mr. T. B. Bridgman obtained two at 

 Brundall, near Norwich ; and in 1876, on the 16th of July, he took 

 seven males at the same locality. These were frequenting Oircium 

 arvense, the creeping thistle. Leon Dufour records, in the ' Annales 

 de la Societe Entomologique de France,' 1838, that the species 

 frequents the flowers of aquatic plants, particularly those of Alisma 

 plantago. Professor Schenck took it on flowers of Rubus ccesius, the 

 dewberry ; it is also said to frequent Lysimacea, the loosestrife.
