Every month in the year is represented by specimens from one or another Mexican 
locality. Examples dated January are from Cordova and two more Southern Mexican 
points, seven in Guatemala, and Sapucay in Paraguay; dated May from Atoyac and 
Rio Janeiro. Some other data have been given above. 
On the habits of this species Mr. Williamson has made the following notes :— 
“Jan. 25,1905. Between Gualan and El Rancho. This species has actions very 
similar to [those of] Pachydiplax longipennis, resting on twig-tips with down-drooping 
wings and upturned abdomen, a common position for Guatemalan Libellulines, several 
of which assume it; most of them have the seventh or eighth abdominal segment 
conspicuously marked. Fly-catchers very numerous. 
“ Gualan, Jan. 23, 1905. Female of this species oviposits, unattended by male, by 
dipping tip of abdomen in open water.—Jan. 22. Native called this ‘Garcite’ (a little 
alligator, literally translated, but meaning more nearly ‘alligator pilot’) *. . 
“San Pedro, Honduras, Feb. 27, 1905. 3 [6] at mouth of gulch. ¢ [mn] in gulch, 
actions like [those of] a Corduline. 2 [m] ovipositing in quiet pool in gulch, dashing 
eges in open water unattended by 3.” 
Prof. Biolley noted the Esparta examples as from “bord fangeux du ruisseau 
Chingo,” those from Surubres as from “eau stagnante.”

In addition to the details given on page 272 :— 
¢. Face and lips reddish-yellow, the red more pronounced superiorly ; tip of vertex very slightly concave, 
frons with a deep superior, mid-longitudinal groove. Sides of the thorax greenish. Abdomen probably 
bright red in life, unspotted, paler beneath ; width decreasing slightly from segment 2 (2°5 mm.) to base 
of 4(2mm.), increasing to the apex of 6 or of 7 (3 mm.), thence decreasing to 10 (1-6 mm. at apex); base 
slightly compressed, as 2 is 3°5 mm. high. Superior appendages reddish, 2 mm. long, subequal to 9+ 10; 
in profile view convex, except at the extreme apex, which is slightly upturned, third fourth slightly 
thicker, with an inferior row of 5-7 denticles ; in dorsal view almost straight. Inferior appendage about 
one-seventh shorter, reaching beyond the last inferior denticle of the superiors. Genitalia of segment 2, 
with the penis projecting, shown in our figure. Legs luteous, the tarsi darker. Antero-inferior row of 
spines on second femora consisting of about 22 very short ones followed by 4-5 much longer in distal 
third ; on third femora of about 27 serrations followed by 4-5 longer spines in distal third. 
Q. Differs from the male, in addition to the features mentioned on page 272, in having the body generally less 
red and more brownish-yellow ; the abdomen attains its maximum width at the apex of segment 8(3 mm., 
apex of 10 2°2mm.). Appendages 1 mm. long, longer than segment 10, not so long as 9. Antero-inferior 
row of spines on second and third femora consisting of about 15 spines on each, gradually increasing in length 
* Of. the names “snake-doctor” and “snake-feeder” applied in many parts of the United States to the 
Odonata. Mr. Williamson also notes that “ Agujas del Diabla” was the name given him at Santa Lucia for 
Odonata.
