74 Orthorrhapha brachycera. 



resembles the pupa of forcipida and has the spines on the first 

 abdominal segment somewhat long and recurved at the apex. 



This species is easily distinguished from forcipula by the dark 

 triangles on abdomen and its compressed shape, by the small male 

 genitalia and the ovipositor which is of quite a different shape from 

 that in forcipula^ also the species is more bristly. 



D. trigonus is common in Denmark; Hillerød, Vedbæk, Tisvilde, 

 Odsherred; on Funen at Langensø, Faaborg and Middelfart; in Jutland 

 at Silkeborg, Svejbæk near Silkeborg, Søndervig, Nymindegab, Frederiks- 

 havn, Skagen and on Læsø; finally on Bornholm at Hasle, My dates 

 are ^^h — ''/s. It occurs mainly on dry and somewhat sandy piaces, 

 often together with forcipula. A pupa was found at Tisvilde in cow- 

 dung on ^^/e, it developed on ^-/g. Poulton 1. c. records this species 

 from England with the foUowing prey: Chloromyia formosa Scop., 

 Mydæa urhana M., Hilara sp., Crambus pratellus Gik., Angitia fene- 

 stralis Holmgr., Ontophagus fracticornis Preyss. 



Geographical distribution : — Europe down into Italy ; its northern 

 limit lies in southern Scandinavia (Småland). 



14. Cutolmus Low. 



Medium sized or somewhat large species of brownish colour. Face 

 somewhat broad, widened downwards, vertex narrowed. Epistomal 

 callus reaching more than half the height of epistoma. Antennæ inserted 

 somewhat above the middle, the basal joint with long hairs below. 

 The facets in front of the eye distinctly enlarged. Dorsocentral bristles 

 reaching to the middle. Abdominal segments with bristles at the hind 

 margin. Front femora without spine-like bristles on the ventral side 

 (in the Danish species, while some other species have them). Male 

 genitalia small, forceps simple; the ventral lamella shining; the eighth 

 segment in the male with a tongue-shaped prolongation at the ventral 

 hind margin (in the Danish species; some other species have no pro- 

 longation). Female ovipositor compressed, high, with the lamellæ 

 not free, wedged in, 



Of the genus 29 palæarctic species are known; one is found in 

 Denmark.
