Female. Length 4-4| lines. — Black; the face with griseous pubes- 

 cence, that on the vertex and thorax above fulvous ; the cheeks, 

 thorax beneath, and the legs with whitish pubescence ; wings hya- 

 line, the nervures dark fuscous. Abdomen fuscous, subopaque, and 

 very closely punctured, the basal segment most strongly so, its 

 apical margin usually more or less rufo-piceous ; the apical margins 

 of the segments with fasciae of pale ochraceous pubescence ; the 

 ventral segments fringed with white pubescence. B.M. 



Male. Length 3^-4 lines. — Head and thorax black ; the face densely 

 clothed with pale fulvous pubescence ; that on the thorax above 

 ochraceous or pale fulvous ; the cheeks, thorax beneath, and the 

 legs with white pubescence. Abdomen fuscous, closely and rather 

 strongly punctured ; the apical margins of the segments with fascia?

This insect appears in July or beginning of August ; it frequents 

 the ragwort (Senecio jacobaza) and also the tansey (Tanacetum vul- 

 gar 'e). The species that most resembles it is C. fasciata. The latter 

 is uniformly a much smaller insect ; and the apical segment of the 

 abdomen is not depressed at the sides as in C. fodiens. The species 

 is generally distributed, and it has been taken in all parts of the United 

 Kingdom.
