fulvous ; the wings subhyaline, faintly clouded at their apical mar- 

 gins. Abdomen — the basal segment, and sometimes the second 

 also, thinly clothed with pale fulvous pubescence, the apical seg- 

 ments have a short black pubescence, the margins of the segments 

 more or less fringed with pale hairs. B.M. 



Having changed the specific name of this species, I may state 

 the reasons for so doing. In the first place, the authentic speci- 

 men in the Linnaean Cabinet is undoubtedly the present species ; I 

 have also ascertained that the next species, formerly considered the 

 retusa of Linnaeus, is not found in Sweden, whereas the present 

 insect is common. The two species may at once be separated by 

 simply examining the calcaria which arm the tibiae ; in A. retusa 

 they are pale testaceous, in A. acervorum they are black. Mr. Kirby 

 was not acquainted with the female of A. retusa ; at least he con- 

 sidered the Linnaean typical specimen to be identical with A. acer- 

 vorum; but on turning to the remarks on the Linnaean type in the 

 ' Monographia,' we at once see the difference between it and the 

 next species ; Mr. Kirby says, " it is smaller, not quite so hairy, nor 

 is its hair of so deep a black " — all characteristics of A. retusa, and 

 not of A. acervorum. 



The synonymy of this and the following species is difficult to de- 

 termine ; the older authors were not apparently acquainted with 

 both species. A - the difference in the two males is at once obvious, 

 Mr. Kirby, with his acute perception of specific differences, at once 

 detected this ; and although he was not so successful in separating 

 the females (if he possessed both at the time of the publication of his 

 monograph), yet in his collection he subsequently placed the true 

 female with his A. liaivorthana. Dours has mixed the females ; for 

 he says, the calcaria are sometimes black, sometimes testaceous. T 

 have examined hundreds of the A. acervorum, but never saw one 

 with pale calcaria. 1 have adopted such synonyma as I feel satisfied 

 may be relied on.
