Rh. conformis is very rare in Denmark, only one specimen, a male has been taken at Silkeborg on /s 1906 (A. Petersen). The species is evidently a spring species, Kowarz took it in April; the specimens were taken on a meadow, where they swarmed in the air with the legs pendulous, and sat on bushes. Geographical distribution:— The species is hitherto only known from Hungary, Britain and Denmark, the northern limit thus seems to lie in our country. 9. Rh. tarsata Meig. 1822. Meig. Syst. Beschr.
