mesonotum evenly, distinctly and somewhat finely punctate, with elongate 

 notauli ; metathorax rugulose, with all tiie arcae obsolete, though trace- 

 able ; areola semicircular and a little broader than long, with the apex weak 

 and truncate ; costulae wanting, basal area rectangular and very short, 

 apophyses distinct ; spiracles large and oval. Scutellum black, of the 

 same convexity as that of (^ . Abdomen oblong, not broader than thorax, 

 immaculate ; petiole glabrous, with distinct carinae, apically dilated and 

 laterally straight, post-petiole transverse ; remainder of abdomen nitidulous 

 and finely alutaceous throughout ; terebra one-third the length of the 

 abdomen. Legs somewhat slender, with the femora not stout ; extreme 

 base of hind tibiae also rufescent. Wings slightly clouded ; radix casta- 

 neous, tegulae black. Length, g mm. 



This female was captured at Whiting Bay, in the Isle of Arran, 6th 

 to 2oth September, 1903. Chitty has also found it at Loch Awe, in 

 May, 1893.]

Head with the vertex not angularly emarginate centrally; of c^ very 

 finely punctate, nearly smooth and somewhat shining, with the mandibles, 

 palpi, the broad cheeks, external orbits partly and the internal entirely, 

 generally a V-shaped facial mark and the clypeus, white ; $ with the palpi 

 and the frontal orbits red. Antennae of $ setaceous and black, with the 

 scape white beneath ; of the 9 not abruptly attenuate apically, centrally 

 white, with the post-annellus longer than the scape. Thorax of $ with a 

 white callosity beneath the radix, and the notauli extending nearly to the 

 disc of the mesonotum ; $ costulae w^anting and apophyses normal ; 

 spiracles large and oval. Scutellum of $ black ; of (^ at least apically, as 

 well as sometimes the post-scutellum, white. Abdomen red, wath the first 

 segment, except generally its apex, and in $ base of the second, black; 

 post-petiole smooth, of S slightly longer than broad ; second segment 

 alutaceous, not punctate ; terebra hardly half the length of the abdomen. 

 Legs slender and black ; anterior femora, tibiae and tarsi red ; femora of 

 9 except at apex, and $ with the intermediate and usually front ones 

 basally, black ; base and apex of the hind femora, and base of their hardly 

 spinulose tibiae, red ; central joints of hind tarsi in S white, in $ flavous, 

 with their apices rufescent; S with trochanters apically red, the front coxae 

 usually white beneath and the intermediate tarsi infuscate. Wings slightly 

 clouded ; radix and tegulae stramineous, latter in $ often partly or entirely 

 infuscate. Length, 8-10 mm. 



The male is very like that of AI. curvus in size and conformation, but the 

 colour of the abdomen, legs and head, and the much more finely punctate 

 mesonotum will distinguish it, as will the white (joints one and base of five 

 excepted) hind tarsi, orbits and mouth, scutcllar and frontal marks from 

 M. abdotninator ; the female agrees with the latter species in its smooth 

 red abdomen and in the terebra being a little longer than the black petiole, 

 but differs in the rufescent frontal orbits, oval metathoracic spiracles, the
