Hymenoptera aculeata. g 



I eluding antennae, legs etc.) is ferruginous red, that of the three 

 apical abdominal segments has a yellower tint (dark orange). 

 The wings are coloured as in the female. 



The ventral segments are simple. In the antenna? the last 



i joint is moderately curved, narrowed to the apex, and obliquely 

 truncated; it is hardly as long as the penultimate joint. The 

 intermediate joints, especially 7 and 8, are somewhat flattened 



! and dilated, widest in the middle of each joint (seen from above 



| joints 7 and 8 are pentagonal). The third joint is about as long 

 as the forth and fifth together. 



The sides of the thorax near the insertion of the abdomen 



; run out into conspicuous blunt and flattened (not spine-like) 

 productions. In the tridentate apical ventral segment the middle 

 spine is extremely long as compared with the two lateral ones, 



i so that, without relaxing the insect and drawing this segment 

 right out, one might almost mistake it for a Sphecius.
