16 THE IMMATURE STATE OF THE ODONATA. 
that nymph very similar to those of A. Junius should belong to the gi- 
gantic and very different A. validus. 
A specimen in alcohol from New Mexico, Dr. Yarrow, differs by a shorter 
and broader mask. Perhaps it belongs to a new, still unknown species. 
A very young specimen in alcohol from Key West Island, Florida, Mr. 
Garman, differs by a large head and very long legs. Perhaps it belongs to 
A. longipes. 
5. ANAX JULIUS. 
Brauer, Voyage of the “ Novara,” p. 63. 
Seven nymphe, male and female, in alcohol and dry. Length, from 28 
to 50mm; breadth, from 6 to 10mm. Coll. Mus. Comp. Zoél. Locality, 
Kanagava, Japan. 
Very similar to the other forms of Anax. Processes as in A. Junius. 
Lateral appendages as in A. formosus. Male projection short, blunt; indica- 
tion of notch at tip. In full-grown female, wing cases reaching segment 
five ; palpus somewhat larger at tip, straighter, superior angle very little 
rounded ; female valve, two thirds of ninth segment. 
The nymphe were received, together with the imago. No other species 
is known from Japan. 
6. ANAX GUTTATUS. 
Burm. Hdb. T. II. p. 340. 
Twelve nymphe, male and female, nearly full-grown, and young, in 
aleohol. Length, 60 to 40 mm.; breadth, 6 to 10mm. Coll. Mus. Comp. 
Zodl. Locality, Ebon, Marshall Island, Pacific Ocean, Rev. B. G. Snow. 
Longer and less broad than the other species. Mask reaching the base 
of hind legs, narrow, more than four times longer than the breadth of base, 
gradually enlarged forward; front margin rounded, cleft; palpus narrowed. 
to tip, superior angle obtuse, rounded ; lower angle forming a very strong 
tooth ; processes unequal, upper part blunt, lower part smaller, angular 
behind; enclosing a very obtuse angle, with a smaller median notch. Legs 
slender, long. Inferior appendages longer than the two last segments ; 
lateral appendages sharply pointed; male projection narrow at tip, cut 
square ; female valve small, half as long as the segment. 
The nymph were received, together with the imago. The supposed 
identity is probable.
