covered with hairs, with paler bands at the apex of the

<? . Face deeply punctured and clothed with long pale

 Mesothorax and scutellum shining, largely punctured, 

 clothed with pale fulvous hairs. Metathorax finely 

 rugose. Abdomen with the posterior margins of the 

 segments narrowly testaceous, densely clothed with pale 

 fulvous hairs, becoming quite grey after exposure, and 

 forming a distinct wide band at the apex of each seg- 

 ment ; pubescence of 6th and 7th segments pale ; beneath 

 with pale apical margins to the segments and long pale 

 hairs ; apical ventral valve rounded and testaceous at 

 the apex. Legs clothed with pale hairs ; tarsi tes- 

 taceous. 



2 . Face sparingly clothed with pale fulvous hairs on 

 the sides ; clypeus largely punctured, orbital impressions 

 filled with brown velvety pubescence. Antennse pale 

 beneath towards the apex. Thorax clothed with rather 

 bright pale fulvous hairs ; mesothorax dull, punctured ; 

 scutellum shining, largely and irregularly punctured ; 

 metathorax finely rugose. Wings with a slight apical 

 cloud ; nervures dark piceous. Abdomen : 1st segment 

 clothed with long fulvous hairs, and with an apical band 

 of rather paler hairs ; 2nd, 3rd, and 4th segments with 

 a short pale erect pubescence at the base, and with 

 a wide apical band of decumbent pale hairs; 5th and 

 6th segments clothed with decumbent brown hairs; 

 apical dorsal valve finely punctured and triangularly 

 raised in the middle ; beneath punctured and clothed 

 with long hairs on the apical portions of the segments.

 tibiae and tarsi clothed with brown hairs, paler on their

Hah. Common on Erica, &c., in heathy localities, in 

 July and August. The pubescence fades very much on 

 exposure. It is easily distinguished from either of the 

 preceding by the decumbent hairs of the 6th segment ; 

 in the other two the hairs are suberect, and form a pro- 

 jecting fringe.
