86 DOLICHURUS. 



Female. Length 7i~9i lines. Black and shining, covered with 

 a thin, loose, hoary pubescence ; the base of the mandibles fer- 

 ruginous, their apex piceous ; the face covered with aurichal- 

 ceous pubescence. Thorax covered with long, thin, hoary 

 pubescence, the disk punctured ; the metathorax opake ; the 

 anterior tibiae in front and all the tarsi ferruginous, the basal 

 joint of the posterior pair usually black; the anterior tarsi 

 ciliated, the intermediate and posterior pairs, as well as the 

 tibiae, spinose. Abdomen : the petiole and base of the first 

 segment black ; the remainder, as well as the second segment 

 and the greater portion of the third, ferruginous. 



This insect is included in the British list with much doubt of 

 its being indigenous. The only specimen is in the National 

 Museum : it was formerly in the possession of the late J. F. Ste- 

 phens, who did not know its locality. The species does not 

 occur near Paris, but in the south of France and Italy is of 

 common occurrence.
