815 A. E. Verrilli— The Bermuda Islands. 403 
Two large Dragon-fiies, of this species, taken at St. David’s I. in 
October, and sent to me by Miss V. Hayward, before they were 
fairly dry, agree well together, but differ so much in color from the 
usual descriptions of this species, that they may indicate a local 
color variety. The head is bright yellow, as usual, but the circular 
mark on the vertex of head, with enclosed spot, is black, though 
showing a tinge of blue iridescence in some lights. Thorax is pale 
greenish on the sides, but yellowish brown or chestnut above, as is 
the upper side of the first abdominal segment, and of the second as 
far as the raised and angulated transverse line, back of which it and 
the base of the third segment are bright malachite green above ; 
Figure 190.—Dragon-fly (Anax junius); ?3 natural size; after Drury. 
the sides of the first and all of the second segment have the same 
green color ; remainder of abdomen in one example is mostly dull 
dark brown, with an obscure blackish median stripe, and with a 
slight tinge of dark blue on the sides ; yellowish brown below. In 
the other the black dorsal stripe is well defined, expanding angularly 
in one or two places on each segment, and forming a narrow band at 
each suture ; sides yellowish brown crossed by the blackish mark- 
ings; venter chestnut-brown; anal appendages large, black, flat, 
with an outer, oblique, distal spur or spine; legs black, becoming 
dark brown on the femora; wings hyaline, tinged with yellowish 
centrally ; pterostigma large, dark brown ; costal margin yellowish ; 
veins nearly black. Antecubitals 15-17; posteubitals 8 or 9. Ex- 
panse, 95™™ and 105™™; length of largest, 74™™. 
A large species occurs, apparently of an _dschna, resembling 
FE, virens Ramb. and 4’. ingens Ramb., but I have seen no perfect 
specimen.
