Two large Dragon-flies, 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) ; % 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, Hat, 

 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 ; postcubitals 8 or 9. Ex- 

 panse, 95 mm and 105 mm ; length of largest, 74 mm . 



A large species occurs, apparently of an uEschna, resembling 

 ^E. virens Ramb. and JE. ingens Ramb., but I have seen no perfect 

 specimen.
