 Trichiocampus rufipes, Andre, Species, i, 82 ; Cat., 19,* 2. 



Antennae about the length of the body, pilose, deep black, the joints 

 distinctly separated ; basal two joints large, third and fourth equal in 

 length, the third curved beneath, the remaining decreasing gradually 

 in length and very noticeably in thickness towards the apex. Head 

 very broad, projecting in front between the antennae, shining, covered 

 with short down ; labrum and mandibles piceous, palpi fuscous. 

 Thorax black, sutures distinct, shining, smooth, covered with fuscous 

 pubescence ; cenchri large, white. Abdomen short, thick, black, anal 

 segment piceous; cerci short. Legs reddish -yellow, coxa3, trochanters, 

 and anterior femora at base black ; apex of tarsi fuscous. Wings 

 smoky, the apical third almost hyaline ; tegulae testaceous, costa and 

 stigma dark fuscous. Near the base of the second cubital cellule is a 

 small horny point. 



The $ is similarly coloured, but the antennas are densely pilose, and 

 there is the process on the third joint. 



Length 2| 3 lines. 



The larva is green, pilose, the sides raggedly in- 

 dented ; head yellow ; the eye-spots and one, or more 

 often two, marks on vertex black. When young there 

 is a brown transverse band on the front. 



It feeds on tall elms, in the leaves of which it eats 

 holes. The cocoon is transparent and is spun either 

 to a branch or attached to a leaf. There are two 

 broods in a year. 



Brischke records Mesoleius impressus, Brischke, as a 

 parasite, and Pteromalus saltans, Rtz., has also been 

 bred from it. 



Common in the Midland and Southern Counties in 

 England ; rare or absent in the north. 



Continental distribution: Sweden, Germany, Hol- 

 land, France.
