 fourths the length of its neighbours; Le 2 small, without seta (as in rostrata) ; Li 1, 

 hinder surface glabrous (as in rostrata), in the typical group 11-14 there are only 

 three seta? (as in messinensis) ; Li 2, with 4 setae, Sp 1 and 2 equal, long and stout, Sa 

 1 much shorter, Sa 2 slender but nearly as long as the Sp; Li 3 with fringe of long 

 hairs along the length of its anterior surface, at its end which is exactly on a level 

 with the end of Li 2 there are only two set«e, a distal long and stout seta and near it 

 a more proximal shorter seta; B 2, setse as in rostrata, surface ciliation as in messi- 

 nensis: Ri with 5 seta? of which four are subequal and the first, situated at the inner 

 angle on the iX)sterior surface, is short and slender like the two proximal setae of B 2 ;

Fig. 13. Same. Maxilla, anterior surface. Sette omitted 

 from Li 1 and Re. Li 2 is partly concealed by Li 'S 

 whose fringe of hair.s passes over it. S 1 to S 5 are the 

 five seta? of Ri ; SI is seen with difficulty from this 

 side, but is very distinct from the hinder aspect.
