Some of the published descriptions? ® seem to imply that all the legs of the black 
females have an external black line, but such is lacking on the second and third pairs 
of tibie *. Ido not find the median emargination of the hind prothoracic lobe of the 
black females mentioned by Mr. Currie®. Females now before me from Pennsylvania, 
Alabama, Tepic, and San Gerdnimo, Guat., indicate that the orange of orange females 
becomes blackish on the abdomen, even while the confluent character of their postocular 
spots is still evident; finally all trace of the postocular spots disappears. Pruinose 
females of this species (e. g., from Jojutla and Iguala) may have been either of the 
black or of the orange form.

Ceratura, Selys, Bull. Acad. Belg. (2) xli. p. 251 (1876); Kirby, Cat. Odon. p. 139 (1890). 
In this genus, which comprises one of the smallest known species of Odonata, three 
differently coloured females (‘ black,” “orange,” and “ citron”) exist, with one form 
of male. Unlike [schnura and Anomalagrion, the postocular spots in all three females 
are confluent with the pale colour of the head; in the male they are not confluent. The 
only species is the following :— 
1. Ceratura capreola. (Tab. V. fig. 26.)

6. Blue on abdominal segment 8 in all the Mexican and Honduras examples in the form of an apical spot on 
each side, although in one from Vera Cruz the two spots are separated merely by a line of black. 
@ (black). Dorsum of abdominal segment 1 chiefly dark brown or black in all the materiaf"before me, instead 
of orange as de Selys states*. However, one from Lima may be an immature black female and it has 
lorange. | 
Q (orange). Labrum with a transverse basal black line in all the material before me, instead of entirely yellow 
as de Selys states ”.
