tively than in the other species ; the scape does not reach back 

 beyond the middle point of the head ; the 1st and 2nd joints of the 

 flagellum are a little longer than wide, the 3rd-8th joints wider than 

 long. The thorax is relatively shorter and wider than in the other 

 species, and is hardly contracted or depressed between the meso- 

 and epinotum. The dorsum of epinotum is fairly distinctly delimited 

 from the declivity in the $ major, but in the g minor the declivity 

 has a rounded brow and merges gradually into the dorsum. The 

 petiole is not notably different from that of rotundatus. The 1st 

 segment of the abdomen is one- third longer than the remaining; 

 segments taken together. The legs are shorter and stouter than 

 in rotundatus or eugeniae. The 1st tarsal joint of the hind legs- 

 only three-fifths the length of the tibia.

" £ . 2-2 - 8 mm. Differs from the type by the colour of the head 

 and thorax, which is brownish yellow and even rusty brown in the 

 larger individuals. In the latter and $ media, the thorax is 

 shallowly compressed, hardly so at all in the £ minima. Quite 

 distinct from A. rixator by the triangular mandibles and the de- 

 clivity of the epinotum, which is not marginate. The ventral lamella, 

 of the 1st joint of the petiole is obtuse, thick, pointing downwards- 

 and very distinct. The pilosity is longer.

" $ . This insect disagrees in one or two slight respects from Mr.. 

 Shuckard's character of Aenictus, ... of these characters the most 

 striking are the slightly opaque whitish wings, with the veins and 

 stigma almost concolorous with the membrane of the wing ; the 

 antennae gradually attenuated from the 4th or 5th joint, and the 

 very clavate femora to all the legs. . . . Nigro cinereus, pubescens,
