of segments 4 (o 7 lieai' a row of seven or eiglit bristles, and five to seven liairs 

 in front, the iinmbers being rather larger on the sternite of the third segment. 



legs.— The mid- and hindcoxae bear two bristles posteriorly at the apex. The 

 iiiiteriiir feinnr bears about fifteen hairs on tlie outer surface and three bristles 

 ventrally before the ajiex, tliere being on the innerside a row of four or five from 

 the a})ex forward. The mid- and himlfemora are also hairy on the outer snrt'aee, 

 and bear a subventral row of hairs on the innerside. The last four or five ventral 

 liristle.s on tlie onterside of the hindfemur are long and stand in a regular row. 

 The bristles at and near the ventral edge of the mid- and hindtibiae are nnmerons, 

 and there are two rows of bristles on the outer surface, besides some additional 

 lateral bristles from the fifth dorsal pair to the apex. The third dorsal pair is 

 represented by a fine hair. The longest ajiical bristle of the midtibia reaches 

 bevond the ajiex of the first tarsal segment. The longest bristle of the second 

 hindtarsal segment rea('hes beyond the apex of the fourth segment. The hairs 

 on the back of the third tarsal segment are numerous. The fifth tarsal segment 

 bears on each side three rather slender bristles, the third pair being somewhat 

 approximate, and there is a fourth short bristle halfway towards the apex. The 

 measurements of the tarsi are as follows : — 



Modified Segments. — The eighth tergite bears a number of bristles above the 

 stigma, and a regular series from the stigma downwards, there being in front of 

 this series an irregular row of shorter ones, as shown in PI. IX. fig. 27. Near 

 the apical edge there is a row of about fourteen bristles, while on the inner surface 

 near the aj)ex there are two rows of short ones. The stylet is subcylindrical, being 

 about three times as long as broad. 



Length : $, 2-na mm. 



This sjiccies comes near to bohlsi and littii, but can easily be distinguished by 

 tlie short rostrum, the frontal tubercle, and the row ofbristles along the genal edge 

 of the head.

Head. The anterior part of the head bears a row of three long bristles before 

 the eve, and another row of five shorter ones between the maxillary palpus and 

 the antennal groove, besides one very long bristle below the eye and a second 

 behind the eye. On the jiosterior jiart of the head there are three rows of stout 

 bristles. The first segment of the maxillary palpus is hardly longer than the third, 

 while the second is as long as the third and fourth together. The rostrum does not 

 quite reach to the end of the forecoxa ; its last segment is about twice the length 

 of the third. 



Thorax. — The three thoracical tergites bear each a postmedian row of bristles, 

 which are heavy but not long, and an antemediau row of short ones, there being on
