of the median segment are two keels which widen out in the middle ; 

 between these is a straight keel. Petiole a little longer than broad, 

 rugose. Abdomen shining, smooth. Wings hyaline; nervures yel- 

 lowish ; tegulae testaceous. 

 Length 3 mm. 



In general appearance this distinct species most 

 nearly resembles A. nitidula, but the striated meso- 

 notum, punctured pronotum and scutellum, separate 

 it sufficiently from the common species ; in having 

 the pronotum punctured it agrees with J?E. rugicollis, 

 Keinh. (only, I believe, a variety of rufipes), but the 

 striated meson otum, the large fovea at the apex of 

 mesonotum, the less strongly punctured scutellum, 

 the almost obsolete scutellar foveaB, mark it out as a 

 very different species. A. subulifera (which has the 

 mesonotum transversely striated) differs in the scutel- 

 lum ending in a blunt spine.

Black; the antennae brownish beneath, striated, longer than the 

 body ; the legs reddish-testaceous, the coxae blackish, claws fuscous. 

 "Wings hyaline, faintly smoky from the radial cellule. Thorax 

 semi-opaque, the mesonotum finely transversely, the pronotum more 

 strongly obliquely striated ;' mesopleurse shining, iinpunctate ; scutellum 

 conical, in front rugosely reticulated, behind shining, faintly punc- 

 tured; median segment rugose, threes-keeled, the middle one not reach- 

 ing to the top. Petiole rugose, longer than broad. Parapsidal furrows 

 faint, narrow, shallow. Abdomen shining. Radial cellule not much 

 longer than broad, <^. 



Length 2*5 mm. 



Most nearly relating to striolata, Cam. ; differing 

 from it in the semi-opaque mesonotum, much narrower 

 and shallower parapsidal furrows, by the mesonotum 

 not having, a furrow in the centre at the base, in the 

 scutellar foveae being much longer and deeper, in the 

 scutellum being blunter and broader at the apex, in the
