1. MlCEOSTILBA HETEEOGENA. 

 PL X, fig. 1, ? . 



Eucoela heterogena, Gir., Verh. z.-b. Ges. Wien, x, 137. 

 Cothonaspis heterogena, Thorns., Oef., 1861, 401. 



Black ; the anterior four knees and the anterior tibiae testaceous ; 

 wings hyaline with a smoky tinge, the nervures black. Antennae 

 nearly as long as the thorax and abdomen united, the third and fourth 

 joints sub-equal; there is no abruptly cut-off club; the joints longer 

 than broad, the last double the length of the penultimate. Shining ; 

 the mesopleurae and mesonotum laterally aciculated ; the mesopleural 

 furrows aciculated and bearing some transverse points. Scutellum 

 rugose laterally and in front, its cup large, finely punctured, sub- 

 orbicular, median segment laterally finely punctured and pubescent. 

 Abdomen scarcely so long as the thorax, shining, bare. First abscissa 

 of the radius about one-half longer than the second, which is curved ; 

 cubitus complete. 



Length 3| mm. 



Foerster describes a M. bidentata which is very 

 nearly related to heterogena ; bistriata, Thomson, is 

 another species. 



Rare. Milngavie, Stirlingshire, August, by sweeping 

 among horsetails. 



Continental distribution: Germany.
