264 HYMENOPTERA ACULEATA. 



little longer than the fifth, joints of the flagellum distinctly 

 broader than long, third in the ? not quite equal to the 

 fourth and fifth together; wings nearly hyaline, nervures 

 dark piceous, propodeum finely rugose, more distinctly so 

 on the basal area ; abdomen finely rugulose, not distinctly 

 punctured, or sometimes in the $ finely punctured at the 

 base of the segments, apices of the segments in the $ 

 slightly impressed, smooth and shining, in the ? rather 

 less rugulose, and more shining than the basal portion, 

 both sexes with a line of white pubescence at the apex of 

 the second, third and fourth segments laterally, apical 

 I'ringe silvery golden in the ^, golden brown in the ?, 

 beneath clothed with pale hairs ; legs clothed with pale, 

 greyish silvery hairs, scopaa silvery, with a brownish 

 tinge. 



L. 5^-7 mm. 



Common, and generally distributed, the first brood 

 appearing in April and the second in July; these used 

 to be considered as constituting distinct species, but the 

 characters are only such as occur in some of the other 

 double brooded species. 



A. nana, Kirhy. — Like the preceding in size and colour, 

 but distinguishable by the following characters, although 

 often far from easy to recognize. 



^ with the antennse longer, the joints of the flagellum 

 as long as, or longer than wide, the mesonotum rather less 

 closely punctured, the abdomen distinctly; so, its punctura- 

 tion clear and well defined, the stipites of the armature 

 are also wider at the apex. 



5 with the antennse more or less piceous beneath, the 

 mesonotum rather less rugulose, the abdomen distinctly 

 punctured, as in the $ , the white pubescent bands denser, 

 and more conspicuous. 



L. 6^-7 mm. 



Common, and generally distributed. Often occurs stylo- 

 pi zed.
