Front tarsi of common shape, longer than the tibiæ, the metatarsus about as long as the three foUowing joints; claws and pulvilli not enlarged. Length 3,5—4 mm. The female of this species shows resemblance to the female of quadrifasciata, and it was also originally confused with it by Zetter- stedt, and it was first later, in vol. VIII, that, advised by Stæger, he distinguished the two species correctly; quadrifasciata is distinguished by the grey spot on thorax, the bands on abdomen being incised and the postscutellum more or less grey, and finally it has the first posterior cell more broadly open. iV. Erichsoni is very rare in Denmark, we have only one specimen, a male, caught many years ago, and without any locality given. Geographical distribution:— Enrope down into Styria and Hungaria; towards the north to southern Sweden; and in Finland. 3. Cutapsus Loew.
