fulvous, the apical joints of the tarsi ferruginous^ and their pu- 

 bescence beneath ferruginous. Abdomen ovate, shining and 

 delicately punctured, the margins of the segments pale fulvo- 

 testaccous and densely ciliated with fulvous pubescence; at the 

 base of the second and third segments laterally, a line of white

 sometimes having a yellow spot about the middle, the antenna; 

 nearly as long as the thorax. Thorax : the disk thinly clothed 

 with pale fulvous pubescence ; the tegulse rufo-piceous ami 

 having a yellow spot in front, the wings hyaline, ii-idescent and 

 faintly clouded at their apical margins ; the four posterior tibiae 

 at their base and apex, and a line on the anterior pair above,

The Melitta malachura of Kirby is probably a variety of the 

 female, having the abdominal fasciae rubbed off. Mr. Kirby, 

 subsequently to the publication of his w^ork, was of the same 

 opinion, as appears by a note in his own copy of the 'Mono- 

 graphia.* 



The HylcBus cylindricus of Fabricius is the male, and the oldest 

 name for the species. Mr. Kirby made a distinct species of the 

 male of the description, considering the dark varieties only as 

 the male ; but the sexes have on more occasions than one been 

 observed ''in coitu" All these varieties belong to one species, 

 and minuter ones might be pointed out, but that will be better 

 done by personal observation of the insects themselves ; hundreds 

 of the males may be captured on fine autumnal days, on the 

 Ragwort; the species is universally distributed, and has been re- 

 ceived from Scotland, Wales, and Ireland.
