JJolichopodidae. 129 



front coxæ a little grey at the base, and somewhat silvery pruinose 

 anterlorly, posterior coxæ grey with the apical part yellow; hind 

 femora with a small, blackish or brownish spot above at the apex; 

 anterior tarsi blackish except the basal part of metatarsus; hind 

 tibiæ a little blackish or brown just at the apex, and hind tarsi black. 

 The legs have short, black hairs, front coxæ a little pale-haired out- 

 wards; posterior femora with one preapical bristle; front tibiæ with 

 bristles above, and one or two on the postero-ventral side, and with 

 a long, thin hair at the apex on the ventral side; middle tibiæ with 

 about four antero-dorsal bristles (one of them dorsal), two postero- 

 dorsal, and one ventral bristle below the middle; hind tibiæ with two 

 dorsal rows of bristles, one smaller ventral bristle towards the apex 

 and above it a row of small bristles; hind metatarsi with about two 

 dorsal, one anterior, and small ventral bristles. Wings slightly tinged, 

 almost hyaline; veins blackish; discai vein with an angular but obtuse 

 bend; axillary lobe small, the anal vein going forwards. Squamulæ 

 pale yellow, with a black fringe. Balteres yellow. 



Female. Epistoma broad, greyish white, distinctly pubescent. 

 Antennæ shorter than in the male, third joint shorter than broad. 

 Front tibiæ without any long hair at the tip. Wings more tinged ; 

 the axillary lobe larger. 



Length about 4 ram. 



D. latilimbatus is very rare in Denmark; we have it not in our 

 coUection, but Mr. Th. Becker in Liegnitz has kindly communicated 

 to me, that he has taken one specimen on Bornholm. 



Geographical distribution : — Europe down into Italy ; its northern 

 hmit is in Denmark (Bornholm), and it occurs in England. 



Remarks: D. nubilus and latilimbatus are easily recognised among 

 all the other species with pale postocular bristles by the pubescent 

 epistoma, and for the males also the hypopygium is characteristic ; 

 the males of the two species are also easily distinguished from one 

 another, as nubilus has a yellow squamular fringe and no long hair 

 at the apex of the front tibiæ, while latilimbatus has such a hair and 

 a black squamular fringe; the females on the other hånd I cannot 

 distinguish satisfactorily; I think nubilus has a more obvious spot 

 above at the apex of the hind femora, and the hind tibiæ more 

 blackish at the apex, these being sometimes almost quite yellow in 

 latilimbatus, and these characters I have used in the table.
