114 Orthorrhapha brachycera. 



hind tibiæ and metatarsi with long bristles on tlie dorsal side poster- 

 iorly to the row of scaly hairs. Wings a little more tinged than in 

 the male. 



Length 3,7—4,7 mm. 



E. decora is very rare in Denmark, only three specimens have 

 been caught; on Funen at Odense and in Jutland at Frijsenborg and 

 Sæby (H. I. Hansen); the dates are in July. 



Geographical distribution: — Europe down into Spain and Italy; 

 its northern limit lies in Denmark, as it is not known from Scandi- 

 navia; it also occm's in Britain. 



Remarks: This species seems to vary somewhat with regard to 

 the pennation of the legs in the female; the above description is 

 made from the three Danish specimens, of which two are females; 

 these have no scaly hairs on the coxæ, the front coxæ have fine, 

 pale hairs, the posterior coxæ have a somewhat dense row of some- 

 what stronger, bristly and black hairs, at most some of the hairs on 

 the middle coxæ are slightly broadened. Strobl says (Mitth. Ver. 

 Steierm. 1892, 76) that the anterior coxæ are pennate; in Wien. Ent. 

 Zeit. XVIII, 1899, 19 he says (about the var. genualis) that all coxæ 

 are pennate, but that in some specimens the front coxæ may be 

 bare, and in one specimen the scales were narrow and on the hind 

 coxæ there w^ere only bristles. Also Becker mentions (Berl. Ent. 

 Zeitschr. XXXI, 1887, 125) a female without scaly hairs on the coxæ. 

 Also with regard to the scaly hairs on the front femora the state- 

 ments are different, sometimes they are stated to be present, some- 

 times absent. — I shall also note here, that Strobl (1. c. 77) mentions, 

 that E. rufiventris has the posterior coxæ pennate, while the above 

 described rufiventris has only hairs on the coxæ, thus also this species 

 would seem to vary in this respect. That my rufiventris is correctly 

 determined I must consider as certain, as I have examined specimens 

 determined by Zetterstedt (as ventralis Zett. (Stæg. in litt.) = rufi- 

 ventris Meig.).
