Head black, with the palpi and mandibles centrally ferrugineous ; 

 clypeus discreted and epistoma prominent. Antennae hardly longer than 

 half the body, sub-dilated beyond the centre and apically attenuate ; infus- 

 cate, with the two central joints white, and the five basal ferrugineous 

 beneath. Thorax immaculate ; metathorax convex and not smooth, with 

 the basal transverse costa wanting ; areola indicated, its apical costa tri- 

 sinuate ; petiolar area not concave, apophyses small, spiracles not quite 

 circular. Scutelluni black. Abdomen oblong-ovate, as broad as the 

 thorax ; black, with segments two to four and apex of the first red, 

 seventh, and sometimes the sixth, apically white ; basal segment slightly 

 curved laterally ; post-petiole glabrous, not longer than broad ; terebra 

 half the length of the abdomen. Legs normal, red ; anterior, with tro- 

 chanters and femora laterally infuscate ; hind tarsi, apices of tibiae and 

 femora, except at the base, black. Wings sub-hyaline ; tegulae black, 

 radix whitish. Length, 7 mm. 



This female is very closely related to Af. graminicola, from which the 

 narrower flagellar white band, convex and not evenly punctate metanotum 

 will serve to distinguish it, although it is, perhaps, hardly more than a 

 variety of that species. 



Both Brischke's Prussian specimens and the single example taken by 

 Hope, near Netley, in Shropshire, upon which alone it finds a position in 

 our catalogue, had the basal segment entirely red. Stephens' record from 

 London, in June, hardly obviates the necessity of confirming this species, 

 if such it be, as British.

Head sub-pubescent, black ; frons very distinctly, finely and closely 

 punctate, convex ; 9 with the mouth and clypeus fulvous, the latter 

 apically deflexed, in $ apically rounded, and in both sexes somewhat 

 deeply discreted ; i with the mouth and whole of the face white. An-

 sub-incrassate apically, with the six basal joints fulvous, the five following 

 white, and the remainder (sometimes also the fifth and sixth) black.
