Hemitt'les politus, n. s. 



Abdornine medio, basi antennarum, pedibusque rufis ; 

 apice femorum et tibiarum posticorum nigris; basi 

 stigmate alba ; aculeus dimidii abdominis longiore. 



This Hemiteles is at first sight like oxypkimus, but the 

 wings have not the fuscous band, the legs are more 

 slender, the 1st segment of the abdomen is much nar- 

 rower and polished, not aciculate, and the aculeus 

 longer. 



Shining, covered with very scattered, erect, stiff hairs, 

 more dense on the centre of the mesothorax, which is 

 slightly wrinkled. Head transverse, sloping behind 

 towards the neck, sides rounded ; the width behind the 

 eyes rather less than the breadth of the eyes ; face 

 transverse, inner orbits parallel, very slightly immargi- 

 nate against the antennae ; face rather protuberant in 

 the centre ; clypeus distinctly separated from the face, 

 prominent and widely rotundate at the apex. Antennae 

 reaching to the middle of the 3rd abdominal segment, 

 filiform ; 1st joint of scape about as long as wide ; first 

 three joints of flagellum subequal in length, about four 

 times as long as wide, the 4th one-third shorter, the 

 remainder gradually tapering, the penultimate joint 

 slightly longer than wide ; flagellum 18 to 19 joints (in 

 the three specimens two had 18 and one 19 joints). 

 Thorax rather short, about one-fourth longer than high ; 

 mesothorax faintly trilobed in front ; metathorax with 

 distinct superior areae ; supero-medial area longer than 

 wide ; hexagonal wider behind than in front ; lateral 

 spines prominent ; intermediate lines on posterior face 

 more or less distinct ; 1st segment of abdomen gradually 

 tapering from base to apex ; spiracles distinctly project- 

 ing, about three times as wide at the apex as at the base, 

 subcanaliculated, sometimes obsoletely rugose, rather 

 more than twice as long as the width of the apex ; 

 remaining segments transverse, the 3rd the widest, this 

 wider than the thorax ; abdomen about as long as the 

 head and thorax ; aculeus about two-thirds the length of 

 the abdomen and straight. Legs slender. Areolet of 

 wings pentagonal, outer nervure wanting, exterior in- 

 ferior angle of discoidal cell just beyond the same angle 

 of the areolet, transverse ordinary nervure almost inter- 

 stitial, transverse discoidal divided one-third from the 

 bottom ; transverse anal slightly post-furchal, divided 

 one-third from the bottom ; emitting nervure distinct.
