330 Syrphidae. 



anterior tibiæ a little paler, sometimes together with the tarsi almost 

 quite yellow. 



Length 7—8,5 mm. 



The species shows no slight resemblance to -S\ macularis, but this 

 species is larger with much more hairy eyes, and it has a Httle blacker 

 antennæ, which are larger and with a longer arista, and the abdominal 

 spots are nearer to each other in the middle or are united. 



S. pundulatus is not rare in Denmark, but has hitherto been taken 

 only on Sealand and Lolland ; Ordrup Mose (Stæger), Dyrehaven, Geel 

 Skov, Ryget Skov at Farum Sø, Donse, Tyvekrog (the author), and 

 at Nyraad near Vordingborg (J. G. Nielsen); on Lolland at Maribo 

 (Sønderup). My dates are ^/o — ^^/e, it is thus an early occurring 

 species. I have taken it in woods on leaves of bushes, the females 

 were often seen hovering quite low on a sandy road and sitting on 

 the road. 



Geographical distribution : — The species is hitherto only recorded 

 from England and Denmark, but according to a couple of specimens 

 sent to me from Mr. Ringdahl, it occurs also in southern Sweden ; 

 this distribution of the species is thus at present known with certainty, 

 but it is not improbable, as suggested by Verrall, that Zetterstedt may 

 have included the species under macularis. Zetterstedt remarks (1. c. 

 VIII, 3142) under lasiophthalmus that this species also occurs in Den- 

 mark, which Stæger had conmiunicated to him, calling the species 

 sexstriatus Wahlb. ; specimens labelled sexstriatus are also found in 

 Stæger's coUection, but they belong to pundulatus; Zetterstedt has, 

 however, not confused pundulatus and lasiophthalmus for, as he says, 

 "teste D. Stæger", this shows that he had not himself seen the 

 specimens.

Male. Vertex somewhat elongate triangular; frons and epistoma 

 broad ; frons æneous, somewhat pruinose, black and shining above the 

 antennæ but yellow close to the antennæ ; epistoma obscurely yellowish 

 and dark yellowish pruinose; it has a black, not broad middle stripe 

 and the mouth edge and lower lateral parts black. Jowls rather 

 broad, a little descending, brownish black, shining. Vertex, frons and 

 epistoma black-haired, the hairs on epistoma rather long. Occiput 

 grey pruinose, the hairs yellow, above some long, black, overhanging 

 hairs. Eyes distinctly hairy, but the hairs short and pale though more
