Bombyliidae. 91 



Of the genus about 530 species are known from the palæarclic 

 region, and from North America about 450 species; I find 6 species 

 common to both regions, and among these the two cornmon species 

 Hemipenthes morio L. and BomhyJius major L. 



I am aquainted with no case of Hymenoptera parasitic onBombyliids. 



Bombyliids earlier recorded from Denmark: — Kramer in 1760 

 (Spec. Insectol. Dan.) records one species, Bomhylius major. Briinniche, 

 1761 (Prodr. Insectol. Siælland.) has three, Musca morio., Bomhyliiis 

 major and B. medius, and in 1763 (Pontoppidan, Danske Atl. I) he 

 enumerates the same three. O. F. Muller, 1764 (Faun. Fridrichsd.) 

 enumerates two, Musca hottentotta and Bomhylius major. About these 

 species it can only be said that B. major is probably this species and 

 certainly so in Muller; Musca morio is probably Hemipenthes morio, 

 and B. medius probably B. minor or SystoecJms sulphureus. Musca 

 hottentotta seems to be one of the clear-winged species of Anthrax, 

 perhaps A. paniscus. Fabricius has no Bombyliid directly recorded 

 from Denmark. Zetterstedt in 1842 (Dipt. Scand. I) enumerates two, 

 Botnbylius major and pumilus = minor (at all events the Danish specimen 

 is minor); in 1849 (ibid. VIII) he further remarks under Lomatia 

 lateralis "In Dania quoque obvia fuerit, significante Lowio". Loew 

 (Linn. Entom. I, 1846, 380) also says that this species occurs in Den- 

 mark, but this must certainly be due to some error, though its 

 occurrence in Denmark is not improbable, as it occurs in Germany 

 and in southern Scandinavia, but here it is rare; should it be 

 found it will be easily recognised; it is a representative of a special 

 subfamily, Lomatiinae. otherwise not represented by us, and it may 

 be known by the characters: it has the cubital vein issuing from the 

 radial vein as in Bomhyliinae, but in contrast to this subfamily it has 

 a short proboscis; the male has the hind margins of the abdominal 

 segments yellow, the female has the first three abdominal segments 

 broadly yellow at the sides. — Finally, Nielsen (Zool. Jahrbiich. Ab- 

 theil. flir Syst. Geogr. und Biol. XVIII; 1903, 647) mentions B. pumi- 

 lus = minor from Denmark. Thus, two species, B. major and minor, 

 were hitherto known with certainty, and probably also Heniipenthes 

 morio and one of the clear-winged species of Anthrax. In the 

 present work 14 species are enumerated.

1. Antennæ distant at the base; eyes separated in both 



sexes, most so in the females 1. Anthracinae. 



— Antennæ approximate at the base; eyes touching or 

 very approximate in the male, well separated in the 

 female 2. Bomhyliinae.
