Pezomachus anihracinus, Foerst. 



A small Ichneumon-like insect ; is not uncommon in 

 this country ; although in form it has all the appearance 

 of a small Diccelutiis, the wings are those of Hemiteles. 

 This insect, after a deal of trouble, Mr. Fitch found in 

 the British Museum, in the collection of Ruthe, standing 

 under the name of Ichneumon gracilliinus, most likely 

 only a manuscript name. 



In a box of ichneumons, chiefly bred specimens, which 

 Mr. Fitch sent me to look over, was the above insect, 

 together with three females bred from Elachista suhni- 

 grella ; and as I have not seen a descrij)tion of the male, I 

 have given it below. 



Nigra, pedibus ochraceis, femoribus et tibiis posticis 

 apice pallide piceo ; abdomine piceo, segmentis anticis 

 marginibus pallide ; areola nulla.

 from the face by a distinct line, with a circular pit at 

 each lateral margin ; mandibles bidentate ; teeth sub-

 as long as wide ; the 2nd one-third shorter than the 1st ;

 marked in front ; metathorax rugose ; supero-medial

 rate ; 1st segment of abdomen slightly and gradually

 large ; styles distinctly projecting.
