VELIA RIVULORUM. Latr. 



Black : sides of the thorax and margins of the ab- 

 domen red : thorax with two anterior punctures : 

 each elytron with one small and three large spots of 

 white ; interior sides of the body spotted with black. 



Length 4 lines, expansion of wings 6 lines. 



Inhabits running streams and is not uncommon ; 

 but with the wings is certainly rare. We have met 

 with this species in a running stream above Fulham 

 Bridge, on the Surrey side, in the month of July.
