Syiphus. 309 



The pupa of this species is again similar to that of nitens and 

 thus with the same elothing of dense, fine spines ; it is fully 7 mm long. 



This species is distinguished by its isolated lunules; moreover it 

 differs from corollae by the black-haired scutellum, further in the male 

 by the small genitalia, and in the female by the larger frontal dust 

 spots between which is a larger and distinct prolongation from the 

 black colour; from latifasciatus it is distinguished by the larger size, 

 black-haired scutellum and further by a less broad hinder eye-margin 

 and smaller vertex, and in the female by the frontal dust spots. 

 S. nitens vvill be the most similar species when its abdominal bands 

 are nearly or quite interrupted, but luniger may, I think, be known 

 by the hinder eye-margin being a little broader and the vertex longer, 

 and also by the generally more yellovv-haired epistoma ; in the female 

 the separated and isolated abdominal lunules seem to be a sure 

 distinction. 



S. luniger is a common species in Denmark; Copenhagen in 

 gardens, Amager, Vester Fælled, Charlottenlund, Ordrup Mose, Erme- 

 lund. Dyrehaven, Tisvilde, Jægerspris; on Lolland at Strandby; on 

 Funen at Odense, and on Bornholm in Almindingen. My dates are 

 ifi/5_i8/jo^ It occurs on flowers on various locahties, often in great 

 numbers; it seems especially to occur in late summer and autumn. I 

 have taken the pupa in the earth in a garden at Copenhagen on ^"'li, 

 it developed on ^^/t, and another sitting on grass in Almindingen on 

 Bornholm on '^/s, it developed a few days later. 



Geographical distribution : — Europe down into Spain and Italy ; 

 towards the north to northern Sweden, and in Finland. Further it 

 is recorded from the Canaries. 



Remarks: The four last described species, nitens, latifasciatus, 

 corollae and luniger form a natural group, as also shown by their 

 larvæ, and they are also rather similar: when the specimens are 

 typical the two former are separated by the uninterrupted bands from 

 the two latter, and the two former species are separated from each 

 other by the respectively black- or yellow-haired scutellum, and like- 

 wise the two latter, of which luniger moreover is separated from 

 corollae by the abdominal spots being isolated from the side margin. 

 As seen from the descriptions specimens occur, however, which are 

 not typical in the said respects, but such specimens may, I think, be 

 distinguished by the characters mentioned in the remarks after each 

 species.
