Long. 6 mm. 



2 . Mandibles simple ; line between the clypeus and face 

 distinct, less so in the middle than at the sides, the face and 

 clypeus sparsely, but not very finely punctured, face broader 

 than long; eyes rather strongly emarginate above the base of the 

 antennae; vertex and front smooth. Antennge 27-jointed, third 

 joint only a little longer than the fourth, twelfth funicular joint 

 quadrate, thirteenth transverse. Notauli short; middle lobe of 

 mesonotum not prominent, rather coarsely punctured, the lateral 

 lobes very sparsely [lunctured ; the sharp anterior edge of the 

 mesopleurse is rather short, extending about halfway towai-ds the 

 spiracle and just extending a little beyond the first longitudinal 

 hollow; epimeral sulcus creuulate throughout. Prepectus antero- 

 ventrally crenulate. Median segment with the apical carina of 

 the basal area only indistinctly indicated laterally; areola very 

 broad, not clearly separated from the petiolar area, smooth, 

 punctured near the sicles ; external area subrugulose, dentiparal 

 and spiracular a.rere a little more rugulose, the spiracular ai'ea tend- 

 ing to be punctured anteriorly ; pleural area distinctly separated 

 from the juxta-coxal on the posterior two-thirds, the carina 

 obsolete anteriorly. Petiole with the lateral teeth between the 

 spiracles and the base well developed. Hind coxae and femora 

 smooth, with a few scattered punctures. Nervulus postfurcal ; 

 areolet pentagonal, distance between the recurrent nervure and 

 second transverse cubital nervure equal to half the length of that 

 nervure, second abscissa of the radius shorter than the second 

 transverse cubital nervure; nervellus angled far below the middle 

 (at about three-fourths), discoidella represented only by a, short 

 stump at that point, entirely obsolete beyond the stump, without 

 a vena spuria..
