Cuba" as from " Near the town of Trinidad, also at Bayamo, in 

 July and August." Mr. McLachlan (/. c, p. 20) refers to this 

 species as from the "island of Trinidad," perhaps erroneously. 



I can find no differences between these two females and that of O. 

 clara from Jamaica. , 



The genus Ortholestes is, so far as known, confined to the West 



Indies.

Genus Lestes. 



De Selys grouped the Neotropical species of Lestes (excluding 



those continental forms found not farther south than Central America) 



as follows : 9 



Rear of the head bronze or blackish, inferior appendages of the male long. 



minutus (Brazil), sublatus (Surinam). 

 Rear of the head yellow, inferior appendages of the male long. 



forficula (Brazil), slriatus (Venezuela), spumarius (Porto Rico). 

 Rear of the head yellow, inferior appendages of the male short. 



exoletus (Brazil), undulatus (Chile), auritus (Brazil), tricolor 

 (South America), pictus (Brazil), tenuatus (West Indies, etc.). 



Of these eleven species I know but six, which, with six hitherto 



undescribed, may be grouped under a slight modification of de Selys' 



arrangement as follows : 



Rear of the head chiefly dark-colored, inferior appendages of the male almost or quite 

 as long as the superiors. 



scalaris n. sp. (West Indies), bipupillatus n. sp. (Brazil). 

 Rear of the head chiefly pale-colored, inferior appendages of the male more than half 

 as long as the superiors. 



forficula, spumarius, mediorufus 11. sp. (Brazil), paulistus n. sp. (Brazil). 

 Rear of the head chiefly pale-colored, inferior appendages of the male half, or less 

 than half, as long as the superiors. 



pictus, tricolor, tenuatus, dichrostigma n. sp. (Brazil), undulatus, quad ri- 

 striatus n. sp. (Brazil). 



The objections to such an arrangement are that in some species the 

 pale color of the rear of the head becomes dark with age and that no 

 means of distinguishing the females of the second and third groups is 

 afforded. With at least one-third of the South American species un-
