92 TENTHREDO BIC1NCTA. 



Black ; pilose, clypeus, labrum, base of mandibles, second, third at 

 the side above, and the three apical abdominal segments more or less 

 above, yellow. Legs yellow, base of coxae, femora, apical third of pos- 

 terior tibiae and the tarsi black. Wings hyaline, clouded at the extreme 

 apex, costa and stigma black. Pleurae opaque, pilose, front smooth, 

 shining. 



The ( has the body beneath and the sides yellow, so also are the 

 coxae and the legs underneath ; the hinder tibiae are black throughout 

 above. 



Length 5 5| lines. 



The antennas have the five apical joints distinctly 

 thickened and shaped not unlike those of Allantus. 

 The four anterior legs have generally the coxae and 

 trochanters black, and the femora have a yellow line ; 

 but it is rather a variable species in this respect. 



Possibly its nearest ally is T. trabeata, Kl. (which 

 is not British), which differs from it in having a broad 

 reddish band, white at the sides, on the middle of the 

 abdomen, the tegulae and a line on the pronotum 

 yellow ; the antennae are not thickened at the apex, 

 while the four anterior tibiae and tarsi have a black 

 line behind, and the posterior tarsi are only annulated 

 with black. 



Bicincta is not uncommon in woods (frequenting 

 flowers, according to Stephens) at the end of May, in 

 June, and beginning of July. It is found near 

 Glasgow, in Berwickshire, Newcastle, Manchester, 

 Worcester, Gloucester, Devonshire, Glanvilles' Woot- 

 ton, in the metropolitan neighbourhood, at Dover and 

 Norfolk. 



It is extensively spread over Europe, inhabiting 

 Scandinavia, Denmark, Germany, Hungary, Holland, 

 France, Switzerland, Tyrol, and Russia. 



Body for the greater part black above, green at the sides and 

 beneath ; legs lined with black above. Antennae short, black, 

 thickened at apex. Clypeus slightly emarginated. Stigma 

 black. Mesonotum opaque, strongly punctured. (Species 17 

 and 18).
