T. terricola is very rare in Denmark, there has only been taken 

 ene specimen, viz. the one mentioned by Zetterstedt 1. c. VIII, and 

 sent to him from Stæger under the name Tachypeza apicata n. sp. 

 It was a female, and it was taken on ^^/g 1848. The species is at 

 present not represented in our collection. According to Zetterstedt 

 the species occurs on shores and at horders of lakes and streams, run- 

 ning in the sand and on the ground, and here very Kable to escape 

 observation. Loew mentions 1. c, that he has only taken it below 

 green turfs. 



Geographical distribution: — Northern and middle Europe down 

 into Germany; towards the north to southern Sweden.

 Epistoma is very short on account of the touching eyes; jowls not 

 developed. Proboscis is short, directed downwards; the maxillary
