23 Orthorrhapha brachycera. 



slender than atricapilla) of the Danish species is easily distinguished by 

 the colouring of thorax and abdomen and by the very pale legs. 



B. linearts is not common in Denmark; Svenstrup between Ros- 

 kilde and Ringsted (H. I. Hansen), Faxe (Schlick), Tureby (Løvendal) ; 

 on Lolland at Maribo (Schlick) ; on Funen at Odense and Hofmans- 

 gave (H. L Hansen) ; in Jutland at Horsens (O. G. Jensen) and at Støv- 

 ring near Randers (A. Petersen). My datas are '^'^le — ^^/s. Schiner 

 says that this species does not sit in the grass but on leaves. 



Geographical distribution: — Middle Europe down into Austria; 

 its northern limit lies in southern Sweden and there it is rare, only 

 one specimen having been taken. 



3. I>asypogon Meig. 



Species of rather large size and somewhat robust shape. Golour 

 dark, generally blackish, more or less with pale designs. Head about 

 as broad as thorax or slightly narrower, broader than high, short, 

 and flat behind. Face rather broad, considerably arched but without 

 any distinct cailus ; the epistomal beard reaches to the middle and is 

 from here produced to the antennæ by shorter hairs. Antennæ inserted 

 near to each other, considerably above the middle. Jowls slightly 

 descending below the eyes. Two ocellar bristles present. The antennæ 

 have the two first joints short and of nearly equal length, the third 

 joint is long and somewhat compressed, it bears at the apex a small 

 one-jointed or at all events indistinctly two-jointed style with a bristle- 

 shaped apex. The eyes have the facets on the front part slightly 

 larger than the others. There is a distinctly bounded clypeus at the 

 lower end of epistoma. Proboscis is slightly shorter than the head is 

 high, it is directed downwards and a little forwards; labium is curved 

 slightly downwards towards the apex and is somewhat pointed, slightly 

 hairy at the end; the basal part is slightly shorter than the apical 

 part. Labrum is as long as the basal part of labium. The maxillæ are 

 straight, not especially strong, with a little tooth at some distance from 

 the apex; the maxillary palpi are indistinctly two-jointed. Hypopharynx 

 is thin, beset with erect hairs over somewhat more than the apical 

 half; maxillæ and hypopharynx are of the same length as the labium. 

 Thorax is rectangular, somewhat oval, high and distinctly arched 

 above; there is a group of præsutural, of supraalar and of postalar 

 bristles, the latter on the postalar callus. In front of the scutellum 

 the thoracic disc has two rows of about five dorsocentral bristles 

 (præscutellar bristles Ost. Sack.). Scutellum without bristles. On the 

 metapleura a row of long, thin hairs; on the hypopleura none. The
