This, the smallest of the Ants, is the greatest of all pests, when it establishes itself in 
a house, as from its minuteness and activity it insinuates itself into every crevice. My 
attention was called to this mischievous creature many years since. Tt was first disco- 
vered in London in a bakehouse, and my impression at the time was, that it had been 
introduced with foreign maize into this country, which is supported by the fact that it 
cannot endure cold +. 
There is no difficulty in obtaining the workers, but the males and females are less 
abundant, and not always to be found. My specimens of these are not sufficiently per- 
fect to ascertain if the neuration of the wings differs materially from the typical species, 
but from Mr. Westwood's figures I am disposed to think that JM. domestica is a species 
connecting the Myrmicæ and Stenamma.

Male slender, pitchy-black, shining; head somewhat ovate, not smooth, eyes promi- 
nent: three distinct ocelli on the crown: mouth ochreous, mandibles large: antennæ 
tawny, approximating, very slender and 13-jointed; scape one-fourth the entire length, 
second and following joints somewhat elongated, the five last being thickened, the apical 
joint the longest and conical. Thorax rather broader than the head and indistinetly 
striated; scutel semicircular and rugose; postscutel with the angles acute. Petiole 
elongated, basal joint long, slender and pear-shaped, second broader and subglobose : 
abdomen ovate-conic, edges of the segments and apex ochreous. Wings slightly tinted, 
stigma and nervures very pale tawny; submarginal cell very long, discoidal, rather small 
and rhomboidal, apical cell elongate and open (fig. 21)}. Legs long and very slender, 
especially the hinder pair, ochreous; thighs and tibiæ pitchy, except at their extremities:

Ew Ber of this insect are known. I first took one at Black Gang Chine, in the 
Isle of Wight, in the middle of October 1829. As this species, I believe, has not been yet 
described, I have sketched its characters.
