218 .Dr. Sharp's Revision of the 



This species resembles H. cinnamomea in colour, but 

 is easily distinguished by its smaller size and punctured 

 abdomen. The antennae are stout, a little longer than 

 the head and thorax, yellowish, a little thickened towards 

 the apex; joint three longer than two, four about as 

 stout as three, about as long as broad, five to ten each a 

 little broader than its predecessor, five slightly, ten dis- 

 tinctly, transverse; eleventh joint stout, as long as the 

 two preceding together. Head broad, but considerably 

 narrower than the thorax, with the eyes rather large and 

 prominent, moderately finely and pretty closely punc- 

 tured. The thorax is nearly of the breadth of the elytra, 

 its breadth about twice its length, the sides gently 

 rounded, finely and closely punctured, with an indistinct 

 longitudinal channel in the middle. The elytra are a 

 little longer than the thorax, pretty finely and closely 

 punctured. The abdomen is blackish, with the base and 

 apex, and the margins of the segments more or less red- 

 dish ; segments two to four are evenly and pretty closely 

 and finely punctured, fifth segment more sparingly punc- 

 tured, sixth nearly impunctate. Legs yellowish. 



In the male, the seventh abdominal segment has, on 

 the upper side before the apex, an ill-defined indistinct 

 elevation, the apex is produced in the middle, in the 

 form of two teeth close to one another, and not very 

 distinct, the hind margin is also again somewhat pro- 

 duced on each side. 



This species is found in company with H. cinnamomea, 

 at Cossus-infested trees. In Germany, however, it 

 appears to have been found among Formica fuliginosa ; 

 perhaps, as is often the case, the tree may have been 

 attacked by the Cossus, as well as tenanted by ants.
