TENTHREDOPSIS LIVIDIVENTLMs. 113 



and otherwise is easily known by the broad, brown 

 band surrounding the eyes. From the next species it 

 may be recognised by the black pleurae, by the four 

 apical segments of abdomen being black at the sides 

 and beneath, and by the larger, stouter body, and 

 thicker antenna?. 



The typical ft< triceps differs from the form I have 

 described in having the third to sixth segments " bright 

 unspotted red," and the sternum pitchy. I have no 

 doubt of the two being identical. Stephens' single 

 specimen was from Bristol ; mine from the south of 

 England.
