apex ; in front of the appendages a deep 

 excision forms a strong, long tooth ; in- 

 ferior appendage one half shorter, slight- 

 ly longer than broad, shalh^wly excised 

 on the tip. Appendages of female short, 

 oval. Wings large, hyaline, neuration 

 black, costa yellow, pterostigma short, 

 brown ; membranula black, white at 

 base; antecubitals 19 — 16; postcubitals

Hab. California, San Diego. 



This species was discovered bv the 

 late G. R. Crotch in 1872. He gave 

 two splendid couples to the Museum of 

 comp. zooi. Later several specimens 

 were collected in northern California bv 

 Lord VV'alsingham ; the collection of the 

 Museum has two males from Tucson, 

 Arizona. An incomplete male (not seen 

 by me) from Guatemala is in M'Lach- 

 lan's collection. Mr. L. Cabot in "The 

 immature state of the odonata. Part 2. 

 subfamily y^^.vcZ'/^///'/" i88i,p. i^, men- 

 tions some nvmphae from San Diego, 

 California, more bulky than A. jioiius 

 and with two black teeth in the middle 

 of the comb of the front border of the 

 mask and another large nympha from 

 New Mexico. It was believed rather 

 doubtful that n\mphae so similar to those 

 of ^.y/zw/zc^ should belong to the gigan- 

 tic and very diflerent A. validiis {=zwal- 

 singhaml) . After anew and detailed 

 study of this subject I think these nym- 

 phae may belong to A. walsinghami.

The color of this species is black and 

 and green but the green is not so beauti- 

 ful as in Lepthctnis vesiculosa Fabr.

There are on the whole continent of 

 iVmerica only four species of Anax 

 known. The gigantic size and brillian- 

 cy of their colors makes it rather improb- 

 able that any new species will be found, 

 but of course it is not impossible. Of 

 the foin- species A. Junius is strictly 

 North American, passing down a short 

 distance to the Isthmus and the Antilles. 

 This species is apparently introduced 

 into the Sandwich Islands, where its size 

 is larger, and in the north in China and 

 Kamtschatka. 



A. lougipes is a South American 

 species, passing along through the An- 

 tilles and Florida and, favored by the 

 Gulf stream, to southern Massachusetts.
