250 BLENNOOAMPA SUBSEEEATA. 



Deep black, shining ; knees and tibiae broadly white at the apex, ante- 

 rior tibiae greyish at the apex. Antennae a little longer than the thorax, 

 stout, the middle joints sharply divided, the apical ones more compactly 

 pressed together ; the ninth joint sharply conical at apex, thinner and 

 longer than eighth ; the third a quarter longer than fourth. Wings 

 smoky ; tr. radial nervure is received in front of third tr. cubital ner- 

 vure. Abdomen short, broad, dilated in the middle ; blotch large, clear 

 white ; terebra slightly projecting. & and cf . 



Length 2 2f lines. 



A species distinguished by its deep, black, short 

 oval body, thickish antennae, and the broad white ring 

 at base of tibise. At the base of the lanceolate cellule 

 is a curled-up impression of a nervure, which likewise 

 forms a distinctive peculiarity. 



It is not uncommon among herbage in May, and 

 appears to have a wide distribution. 



Continental distribution : Sweden, Germany, Hol- 

 land, France, Italy, Hungary, Russia. 



Tegulae and extreme base of pronotum white ; apex of femora, 

 tibiae and tarsi, white. Antennae longer than abdomen, thin, 

 the third joint longer than fourth. Wings hyaline, third 

 cubital cellule longer than second, dilated at apex ; transverse 

 radial cellule interstitial or received in fourth cubital cellule
