Long. 6 mm. 



y . Mandibles simple ; line between the clypeus and face 

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

 cl3'peus sparsely, but not veiy finely punctured, face broader 

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

 antennse ; vertex and front smooth. Antennae 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 spai'sely jmnctuied ; the sharp anterior edge of the 

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

 spiracle and just extending a little beyond the first longitudinal 

 hollow ; epimeral sulcus crenulate throughout. Prepectus antero- 

 ventrally crenulate. Median segment with the apical cariua, of 

 the basal area only indistinctly indicated laterally ; areola very 

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

 punctured near the sides ; external area subrugulose, dentiparal 

 and spiracular areas a little more rugulose, the spiracular area 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 postf ureal ; 

 areolet pentagonal, distance between the recurrent nervui'e and 

 second transverse cubital nervure equal to half the length of that 

 nervure, second abscissa of the radius shorter tha.n 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 bej'ond the stump, without 

 a vena spuria.
