posteriorly. From this dilated part downwanl the arm is not again widened, 

 being praotieall}' of even width and visibly carved. The ventral (horizontal) 

 arm is one-third shorter than tlie vertical one. Its dor.sal margin is nearly 

 straight and its apex so trnncate ohliqnely that the upper angle is acute. The 

 apical margin bears three long bristles, of which the central one is the longest 

 and the ventral one the shortest. There is a fairly long hair at the npper angle, 

 several similar ones along the ventral margin, and a number of short ones at the 

 upper margin and on the side. ? . The seventh abdominal sternite (text-fig. 3)

is divided by a narrow sinns, whieh almost extends frontad to the row of bristles, 

 into a broad npper lobe and very much smaller, especially much shorter, lower 

 lobe, the segment being also ventrally broadly excised, so that the lower lobes 

 of the two sides are separated from each other by a sinus. The eighth tergite 

 bears a ventral row of four strong bristles, there being another strong bristle 

 above the row. The last one of the row is situated at two-thirds the way from 

 the third bristle to the strong bristle of the apical margin. The latter bears as 

 usual a snbventral sinus, which divides the apex of the segment into a small 

 pointed ventral lobe and a larger upper lobe, the latter being rounded in the 

 new species. At the edge of the sinns there is one strong bristle, which is 

 accompanied above by two small bristles and below by one.
