Japyx puecelli, n. spec. 



Ivory-white turning to pale straw colour in the adult, but with the 

 three penultimate segments and the forceps pale chestnut brown. 



3' . Head ovate, almost white, but having in the centre of the 

 frontal part an orbicular, slightly flavescent patch limited by a trans- 

 verse arcuate impressed line ; the posterior part of the head is gTooved 

 longitudinally, and the median part of the base is distinctly emargi- 

 nate; it is dotted with numerous i-igid setae, apical joint of maxillary 

 palpi longer than the preceding, and projecting beyond the mouth 

 cavity ; the antenna reach as far as the apex of the metathorax and 

 have thirty-six joints, which are moniliform, swollen in the middle 

 where there is a distinct ring of not closely-set setae, and decreasing 

 gradually in size from the four basal joints which are glabrous, of 

 equal length, slightly conical, but not quite as wide as the fifth ; the 

 three leg-bearing segments are produced on the upper side in a plate 

 slightly overhanging the connecting membrane, attenuate obliquely 

 backwards and longitudinally grooved in the middle, but not so 

 deeply as in the seven abdominal segments following, which are 

 transverse, twice as wide as long, of nearly equal width and have 

 the edges sharp and horny, but the seventh is sharply toothed in the 

 posterior angle, the eighth segment is horny, like the two following, 

 and a little narrower than the one before, the ninth is of equal width
