dense pubescence below, but this is erroneous, in the male only the 

 front and hind femora have this pubescence, but in the female it is 

 present on all femora; Stein has probably examined a female and 

 then concluded the facts to be the same in the male. 



T. longicornis is rare in Denmark and has only been taken on 

 two occasions, on Lolland at Maribo (Schlick), and in Jutland at 

 Frijsenborg near Aarhus (H. J. Hansen); on the latter locality it was 

 taken in great numbers. The dates are ^^/g to towards the end 

 of July. 



Geographical distribution: — Europe down into Italy; towards 

 the north to middle Sweden. Stein took his specimens when it was 

 cloudy weather, and they were sitting at the points of branches or 

 on fir-needles. 



18. Clielipoda Macq. 



Small, yellow coloured species. Head somewhat elongated, and 

 slightly flattened, as broad as thorax. Occiput somewhat arched, with 

 a few bristles above. Eyes somewhat large, a little elongated, with 

 the hinder margin roundly incised. They are separated in both sexes, 

 but below the antennæ only narrowly separated; the facets are of 

 equal size. In the living specimens the eyes are metallic green, violet 

 behind in the male and unicoloured metallic green in the female. The 

 incisure in the inner eye-margin is small but distinct. Vertex with a 

 small tubercle with three ocelli and a pair of bristles. The antennæ

are inserted near to each other, somewhat below the middle; they are 

 five-jointed, the two basal joints are short, the third a little elongated, 

 pyriform and compressed, terminating with a long, two-jointed arista, 

 the basal joint of which is very short. Epistoma is very narrow, a 

 little broadened downwards; jowls not developed. Proboscis is short, 

 stretched downwards. The mouth parts I have otherwise not been 

 able to examine, they are very probably similar to those in the fol- 

 io wing genus Phyllodromia. Thorax is rectangular, a little narrowed 

 in front, not much arched above; pro- and metathorax small. There 

 are a few (four, two in each row) long, uniserial dorsocentral bristles, 

 the anterior is placed inwards to the humeri ; there are no acrostichal
