and 15 postnodal nervures ; triangle about three times as long as 

 broad, consisting of 4 cells, followed by 5 or 6 cells, and then by 2 

 increasing ; 2 supratriangular nervures ; 3 cross-nervures in the sub- 

 triangular cell; lower triangle free (which corre.-fponds to the sub- 

 triangular space in Libellulince). Hind wings with 15 antenodal 

 and postnodal neivures ; triangle about twice as long as broad, con- 

 sisting of 4 cells, followed by 4 or 5 cells, and then by 3 increasing ; 

 2 supratriangular nervures ; 4 cross-nervures in the lower basal cell ; 

 lower triangle transverse. 



Chili (Edmonds). 



The specimen appears to be a male, but the abdominal append- 

 ages are too much damaged for descri|^ition. It is the first Anax 

 described from Chili, and is remarkable for the very short ptero- 

 stigma, which separates it from all the other species of the genus 

 with which 1 am acquainted. 



Sapho pulchella. 



Exp. al. 64-70 millim. 



Male. Bronzy black above, head spotted with tawny, the ocelli 

 being placed in the middle of four tawuy spots ; thorax with the 

 lateral lobes almost entirely surrounded with tawny, the pleura 

 striped with the same colour, and the under surface somewhat pru- 

 inose ; legs black, femora testaceous, marked with a black line. 

 Abdomen with a tawny spot on the sides, at the base of the first five 

 segments, and a tawny lateral stripe on the sides of the first seg- 

 ment, continued more narrowly on the second and third, where it is 

 coppery. Wings bright orange-tawny or coppery, iridescent, paler at 

 the base ; stigma brown, enclosed by black lines, about four times 

 as long as broad, the lower side projecting basally in a point ; 

 neuration very close ; antenodal nervures upwards of 40, and post- 

 nodal nervures numbering 50 or (iO. 



Female. Body similarly coloured, but wings brownish hyaline, 

 with a fiery copper iridescence in certain lights, and a narrow milk- 

 white band on both wings, not quite extending to the costa or inner 

 margin, and curved on the hind wings, placed considerably beyond 

 the nodus. On the abdomen, the tawny spots at the base of the 

 segments and the tawny lateral line are continued on all the five 

 segments which remain. 



Hab. Cameroons. 



Size and shape of S. longistic/ma, Selys, a specimen of which was 

 received in the same collection, but with the abdomen rather shorter 

 and stouter. 



Genus Tatocnemis. 



Male. Wings long and narrow, petiolated to the level of the 

 arculus, with three concavities on the hind margin, between the 

 subcostal radius and the lower sector of the arculus ; fore wings 

 with 24-28 and bind wings with 20-21 postnodal nervures; 

 pterostigma broad, lozenge-shaped, covering 1| or 2 cells. The 

 median sector rises at or a little beyond the nodus, the subnodal
