EMPHYTUS MELANARIUS. 271 



Antennae nearly as long as the abdomen, the third joint slightly shorter 

 than fourth. Wings clear hyaline, costa fuscous, stigma black, pale at 

 the base ; second recurrent nervure received close to first transverse 

 cubital. ? . 



The <$ similar, but antennae thicker, the abdomen wants the white 

 band, and the four front femora are lined with black over the apical half. 



Length 3 lines. 



Very similar to cinctus, but smaller and more slen- 

 derly built, the wings clearer, the antennae longer and 

 thinner, the mouth, thorax and legs marked with white, 

 and the tarsi fuscous. The hinder tarsi, too, are longer 

 compared to the tibiae, while the blotch is much larger 

 and more distinct, being shaped like a triangle. In 

 cinctus it is broader, but not nearly so long nor so wide 

 in the middle. 



Tenthredo togata, Fab., is usually regarded as iden- 

 tical with cinctus, but I believe it to be the present 

 species, with which the description agrees tolerably 

 well, especially with the words "ore albo," "margine 

 ante alas albo," which do not fit cinctus, and are parti- 

 cularly characteristic of cingulatus, while the other 

 terms used by Fabricius, " Segmento primo macula 

 magna dorsali," are quite descriptive of the large 

 blotch, and not applicable to the abdomen of cinctus ; 

 the same may be said (although to a less degree) of the 

 description of the legs, " pallidi femoribus maculis 

 nigris." There can be no doubt about its being the 

 cingulatus of Lepelletier and Stephens, only the former 

 has a var. " ore humerisque nigris," which probably 

 belongs to cinctus. 



Rare compared to cinctus: Darenth, Glanvilles* 

 Wootton. 



Continental distribution : Germany, France.
