SUB-TRIBE DOLEEIDES. 157 



On the Continent it has been recorded from Ger- 

 many, France and Switzerland. 



Sub-tribe DOLERIDES. 

 Genus DOLEEUS. 



Dolerus, Jurine, Hymen., 56. 



Wings with two radial and three cubital cellules ; the first cubital 

 small, the second long and receiving the two recurrent nervures. 

 Lanceolate cellule with an oblique cross ncrvure. Basal nervure 

 straight, received at a distance from cubital. Costa dilated before 

 stigma. Transverse median nervure received in middle of discoidal 

 cellule. Stigma black, often pale at the base. Two middle cellules in 

 hind wings. 



Antenncc 9-jointed, generally inserted immediately over the clypcus, 

 not longer, if not shorter than the abdomen, the third joint a little 

 longer than fourth. 



Legs of moderate length, patellae distinct ; claws armed with a minute 

 tooth; calcarea short and rather blunt; posterior tarsi shorter than 

 tibia). 



Head with the vertex thick ; suture not very distinct. Eyes small, 

 not reaching to base of mandibles. Clypeus large, incised, but not 

 deeply. Labrum of moderate size, rounded at apex. Mandibles with 

 three subapical teeth. See PI. XII, fig. 14. 



Thorax with the sutures and parapsides distinct. Cenchri large, 

 oval. 



Abdomen sharply contracted from sixth segment ; the blotch small, 

 but distinct enough. The dorsuni is often keeled; cerci large. Saw 

 short. 



The species of this genus have generally the head 

 and thorax more or less punctured, and covered with 

 longish hair. Most of the species are black, or black 

 with the legs more or less reddish, or more rarely 

 white ; or the abdomen may be banded with red, in 

 which case the legs may be either entirely black, or 

 black and red. With the red-banded species the sexes 

 often differ very much in coloration, while they have 

 the antennae longer. Their bodies are generally 

 thickish, but are more cylindrical with the red-banded 

 species. 



The Dolerides are chiefly vernal species, in fact, they 

 are amongst the earliest to appear of the Tenthre- 

 (litidce, and are often found on willow catkins. Not 

 much is known about their Iarva3, but so far as they
