alothorax. 
Clypeus , in width, a little less than the radius of the anterior 
eyes; in direction, retreating. 
Sternum long; narrower behind. Anterior coxae separated by 
the width of the labium. 
Maxillx twice as long as labium, widest in the middle, taper¬ 
ing toward apex. 
Labium as wide as long, truncated at tip. 
Fakes stout and long; vertical; slightly diverging. 
Legs slender, differing but little in thickness; the third and’ 
fourth pairs devoid of spines. Relative length 4, 3, 1, 2. Pa¬ 
tella with tibia of the third shorter than patella with tibia of 
fourth. Metatarsus with tarsus of the fourth shorter than

Abdomen long, slender; much narrower in the middle. 
. _ Si ^° nd ^ makes the fifth genus of the sub-family Lyssomanm, which 
includes those Attidae which have the eyes in four transverse rows. 
Janus rayrmeciafformis Tacz. is nearest to Simonella, and Dr.Taczan- 
owski, in describing the species, suggests that it ought to constitute a 
neu genus. It differs, however, from Simonella, in that the first rowof 
eyes occupies the whole of the face, and in the quadrangle of the eyes 
’mug longer than wide. Simonella is easily distinguished by its nodose 
form from the other genera of tide sub-family. In general appearance 
it most resembles Synemosyna Hentz.
