84 TENTHEEDO LACHLANIANA. 



9. TENTHEEDO LACHLANIANA. 

 PI. VIII, fig. 1, ? ; la, antennas; 1&, head. 



Tenthredo lachlaniana, Cam., Fauna, 12, 6 ; Andre, Species, i, 



453; Gait., 56,* 16. 



Black; mandibles, clypeus, labrum, inner orbits of the eyes; a 

 triangular spot between the antennae; tegulse, edge of the pronotum, 

 and two spots over the posterior coxse, whitish-yellow ; third, fourth, 

 and fifth abdominal segments red, as are also the apices of the four 

 anterior femora, and the tibiae and tarsi. The thorax is opaque, head 

 and abdomen shining. Wings hyaline ; costa and stigma pale fuscous. 



What I regard as the $ has the antennae longer, the colour of the face 

 is the same, only the white is wider round the eyes. The legs are red, 

 same a black line over the femora, and the coxae in part behind. The 

 breast is reddish, and there are two yellow streaks on the pleurae ; the first 

 going from near the tegulae to the middle coxae, the second is short and 

 more curved in form, and nearly joins the first at its lower end. The 

 scutellum has two small yellow marks behind, and the abdomen is 

 entirely red beneath, black on part of the first and the two last 

 segments. 



Length 5 6 lines. 



This species is no doubt confounded with monilidta, 

 from which, however, it may be readily known by 

 having the inner orbits of the eyes and the posterior 

 femora quite black ; the markings on the head, thorax, 

 and abdomen are white, not yellow, and the posterior 

 tarsi and apex of tibige are not marked with black. In 

 rnoriiliata, too, the tegula3 are reddish, in the present 

 species white, which has also two marks over posterior 

 coxaB instead of one as in Klug's insect. 



In one of my Scotch specimens the red abdominal 

 band is very obscure, and two others have only one 

 side of the pronotum white. 



Three specimens were taken by myself at Rannoch, 



in June, and another by Dr. Sharp at Braemar ; the 



$ I took near Gloucester. I have also seen a German 



specimen taken by Prof. Zeller, and Andre records 



it from Finland and Switzerland.
