A pale species. 



Head.— The occiput is more than twice as long as the fmns (measured along 

 the side) in the c?, while the occipnt and frons are nearly the same length in tiie ? . 

 There are five (cj) or four (?) bristles along the oral edge, of which the anterior 

 one is very long, and three (cJ) or two (?) more in front of the eye. The occipnt 

 bears only one series of bristles situated near the apex, and in the S a number 

 of short liairs in the dorsal depression. The row of sliort hairs above the antennal 

 groove extends to the insertion of tlie antenna. These hairs are thin, and the 

 anterior ones in the S, or all in the ? , are rather far apart. The first and second 

 segments of the maxillary jialpns are of the same length and one-fourth longer 

 than tiie tliird, while the tunrth segment is as long as the second and third together. 

 The laliial palpns consists of five segments, the last reaching to the end of the 

 forecoxa and being about as long as the two preceding segments together. 



Thorax.— The pro-, meso-, and metanotnm bear each two rows of bristles, but 

 the anterior row of shorter ones contains only a small nniuber of bristles. The 

 mesonotniu bears in addition a row of very fine and long hair-like spines before 

 the apex. The epimeruin of the mesothorax bears four long bristles, two standing 

 before the middle— namely, one above and one below, and two near the stigma. 

 The metathnracical epimerum bears two or three bristles [i) or four (?) from 

 the stigma downwards. 



Abdomen.— The abdominal tergites bear eacli one row of bristles. On the 

 first three tergites there are moreover some short bristles representing the median 

 row. The stigma stands above the ventral bristle, its diaiueter being twice the 

 length of the diameter of the groove of tlie ventral bristle. The seventh tergite has 

 on each side one stout apical bristle. The basal sternite bears on each side one
