390 SUPPLEMENT. 
Ischnura demorsa (p. 128). 
3. In the third line of the description, anted, page 128, insert “ of 8” after “base.” A male from Nogales has 
the left inferior appendage trifid by reason of the normally superior branch being itself bifid. 
Q (intermediate between black and orange forms). An otherwise black 9 from Yurecuaro has the posterior 
dorsal half of segment 8, the posterior two-thirds of 9, and a small median dorsal spot on 10, blue; on 8 
and 9 the anterior margin of the blue is trilobed, the median lobe being more pointed and extending a little 
farther forward than the other two. Another female from the same locality, agreeing generally with the 
black form, has 8 and 9 coloured as just described, but the blue postocular spots are confluent with the 
pale colour of the rear of the head. A third 2 from Yurecuaro has the postocular spots and the pale 
colour of the thorax orange, the postocular spots confluent with the pale colour of the rear of the head, 
the black humeral stripe a little wider than the pale antehumeral, segments 1 and 2 orange but the dark 
metallic-green dorsal markings are wider than described for orange females on page 129, line 2, anted, 
3-7 as in the black 2, 8 with a small dorsal anteapical trilobed blue spot, 9 blue with a pair of 
triangular dark spots at base. 
Two other females from Yurecuaro are of the orange form, but they and the third female above described have 
no notch on the middle of the hind prothoracic margin. 
A vulvar spine is lacking in almost all these supplementary females; the exceptions are an old female from 
Yurecuaro and one from Nogales, in which a small or very small spine is present.

To the localities given, add :—Mexico, Altamira (Hoag, coll. P. P. C.: 1 transit. 2 ) 
in Tamaulipas; British Honpuras, Belize [2 ¢, 1bl. 9]; Guavemaua, Puerto Barrios 
[1 bl. ¢ ], Los Amates [1 ¢], Amatitlan [1 bl. 2]; Honpuras, Puerto Cortez [8 ¢, 
6 bl. 2, 5 or. 2 | (Williamson, Deam, coll. Wilmsn.). 
Mr, Williamson made the following notes on this species: “Los Amates, Jan. 17, 
1905, ¢. In bog across river from Los Amates on trail to Dr. Johnson’s.” “Puerto 
Cortez, March 2,1905. 3. In Pontederia beds 20 feet from ocean” [hence associated 
with Ceratura capreola, q. v. |. 
I have now evidence which has convinced me that the “ orange female” of this 
species is a younger stage of the “ black female.”
