1. DOLERUS PALMATUS. 



Dolerus palmatus, Klug, Berl. Mag., viii, 236; Ste., Ill, vii, 



87, 6; Htg., Blattw., 235, 16; 

 Thorns., Hym. Scand., i, 279, 1; 

 Cam., Fauna, 49 ; Andre, Species, 

 i, 271 ; Cat. 34,* 26. 



Black ; head and pleurae covered with a long grey pile ; mesonotum, 

 very shortly pilose and pretty deeply and coarsely punctured through- 

 out. Vertex opaque, finely punctured ; upper part of pleurae punctured, 

 but not so deeply as the mesonotum. Clypeus deeply incised. Cenchri 

 large, clear white. Legs black, covered with a short, whitish pile ; 

 anterior tibiae and tarsi fuscous ; knees and anterior tibiae in front dull 

 white ; calcaria yellowish-white ; the tarsal joints pale at the extreme 

 apex. Wings hyaline ; costa and stigma fuscous ; tegulae pale fuscous. 

 Antennae short. 



The <? has the abdominal segments marked with thin white lines at 

 the junction of the segments ; above there is a long thin white line on 

 the first, second, and third and at the apex, and a large membranous one 

 on the centre of the fourth and fifth, sometimes also on the sixth. 



Length nearly 4 lines. 



This scarce species is readily known from all the 

 others by the white colour on the legs. 



I have seen a d taken by Dr. Sharp at Dairy, and 

 Stephens records it from Hertford and Darenth Wood. 



Continental distribution : Sweden, Germany, France.
