Mule. Reddish; head subquadrate with distinct punctures, bind ocelli further 

 from each other than from the eyes, mesonotal punctures strong, basal areas of 

 metanotum long, mesosternum with two broad, blunt, transverse teeth, petiole of 

 abdomen nodose though not constricted on the sides, strongly punctured, abdomi- 

 nal punctures sparse, two submarginals, a dusky cloud in the hind margin of the 

 wing, legs fuscous. 



Testaceo-rufous ; moderately slender; head subquadrate, produced and 

 broadly rounded, punctures rather strong, separated so that a line from the 

 eyes to a hind ocellus passes through five punctures. This line is slightly 

 shorter than the distance between the bind ocelli, ocelli rather small. There is 

 no depression or groove above the antennas, but the space in front of the ocellus 

 is impunctate. A short clypeal ridge runs upward toward the antennae. Pro- 

 clinate and erect hairs of the head very sparse. Antennas rufo-testaceous, as 

 long as head and thorax. Prothorax with a rather strong, irregular, subconfluent 

 punctuation ; mesouotum with strong, close, rounded punctures, the grooves 

 much shortened; scute 11 urn closely rugosely punctured; metanotal reticulum 

 rather fine, the basal areas narrow, equalling four of the meshes in length ; 

 mesopleura' confluently punctured in front, mesosternum coarsely punctured, 

 with two very prominent sub-transverse teeth near the front portion, the teeth 

 transversely grooved so as to be bicuspid ; vestiture of thorax and petiole long, 

 sparse, erect, whitish, in front with deflexed hairs also. Petiole of the abdomen 

 one-third longer than broad at tip, its sides nearly straight, subnodose apically 

 and constricted at the very tip, deeply and coarsely punctured, the anterior 

 angles acute, venter coarsely rugose, medially crenulate; second segpient 

 sparsely and finely punctured except on the sides in front where the punctures 

 become stronger and closely aggregated, its pubescence sparse, partly short and 

 caudally deflected and partly long and erect, apically closely punctulate and 

 with a short fringe of white subserrate hairs, third segment with a conspicuous 

 speculum and a broad punctulate apical margin, its pubescence sparse, erect, the 

 apical fringe sparse, the hairs not evidently serrate, remaining segments similar, 

 pygidium finely margined and aciculate; venter similar, the punctures of the 

 second segment stronger and closer than above, no apical fringes. Legs testa- 

 ceous, the femora and tibiae fusco-testaceous apically, the hairs and spurs whitish. 

 Wings subhyaline, veins narrow, dark brown, stigma hlack, third submarginal 

 cell wanting, first cubital vein blackened on its costal two-thirds, thence whitish, 

 a suffused brownish spot in the middle of the hind margin. 



Length, 7.5-9 mm.
