GENUS SAROTHRUS. 167 



beyond the base. Hind tarsi distinctly longer than the tibiae. Radial 

 cellule short ; areola distinct ; spurious nervures clearly defined. 



The $ has the antennae longer than the body, the third joint incised, 

 twice the length of the fourth, the last joint about one half longer than 

 the penultimate. 



Length 4 mm. 



Rare. 



Continental distribution : Sweden, Germany. 



Genus SAROTHRUS. 



Sarothrus, Htg., Germ. Zeit., ii, 187. 



Amphithectus, Htg., 1. c. 



Melanips, Giraud, Verb. z.-b. Ges. Wien, x, 163 (pt.). 



Thorax smooth, shining ; parapsidal sutures distinct, sometimes with 

 a deep furrow between them ; scutellum rugose, ovate, bifoveate at the 

 base. Abdomen ovate, the second segment pilose; petiole smooth, 

 shining. Antennas filiform in $ , the joints towards the apex monili- 

 form ; the third joint incised in $. E/adial cellule closed; the areolet 

 open on lower side ; cubitus obsolete. Eyes oval, bare. 



The antennae are shorter than the body in the ? , 

 equal to it or shorter in the $ ; the joints longer 

 than broad, the third joint considerably longer than 

 the fourth. The parapsidal furrows are complete, as 

 in canaliculatus ; or semi- complete, as in areolatus. 

 Middle segment thickly haired, bicarinate. Meso- 

 pleuraB shining, the longitudinal furrow distinct. The 

 abdomen in canaliculatus bulges out in the centre, 

 and is not longer than the head and thorax united ; in 

 areolatus it is longish and strongly compressed. The 

 areolet is complete or incomplete, and the spurious 

 veins may be distinct or indistinct. 



May be known from Melanips by the thorax not 

 being granulated and opaque ; in having the thorax 

 shining it agrees with Dicderea, but that genus has the 

 scutellum smooth, and the second abdominal segment 

 bare. 



Nothing is known about the habits of the species, 

 which are found in meadows and frequent flowers, 

 especially of Umbelliferss. Only two European species
