transverse, eleventh long, longer than the two preceding, often light- 

 coloured ; tliorax more or less pitchy, about as broad as elytra, twice as 

 broad as long, narrowed in front, sinuate near exterior angles which are 

 distinct, closely and rather plainly punctured, with an indistinct 

 impression before scutcllum ; elytra rather longer than thorax, very 

 transverse, somewhat rugosely punctured ; hind body shining, segments 

 2-4 sparingly punctured, 5-6 impunctate, sides and apex with long 

 exserted setae ; legs reddish yellow. L. 3 j mm. 



Male with the hind margin of dorsal plate of seventh segment of hind 

 body distinctly emarginate in middle.

 wards ; uot recorded from the Northumberland district ; Scotland, local, Tay, Dee, 

 and Moray districts. 



N. confusa, jNIaerk. Verj- like the preceding, but smaller, and a 

 little more shining ; the antennae are rather thicker, and have joints 

 4-10 plamly shorter and more transverse ; the sides of the thorax are a 

 little less rounded ; moreover, the hind body is more closely punctured, 

 the base of the lifth segment being distinctly punctured ; the sexual 

 characters are much the same as in N. flavipes. L. 3 mm. 



Rare ; in nests of Formica fuliginosa ; ilickleham (Champion), Tilgate, Charlton, 

 Birdbrook (Power and F. Smith) ; in the latter locality Dr. Power has found the 

 species somewhat plentifully.

AIiIANTA, Thomson. 



This genus is here understood as including .4Z/a?2fa, Thorns., Discerota, 

 Muls. et Rey, and Heterota, Key, which, together with the two preceding 

 genera, are separated from Homalota proper by the evident separation of
