Lepthemis cardinalis, Hagen, Proc. Bost. Soc. Nat. Hist. xviii. p. 74 (1875) ’ (Panamaexample only). 
3. Prof. Hine noted of the Morales example :—* Bright red all over except thorax above when taken.” In 
the dried specimens the labrum is somewhat orange, the labium luteous, both lips without any dark 
markings, thoracic dorsum somewhat greenish. Abdomen 2°5 mm. wide at segment 2, 1‘5 mm. at base 
of 4, 2°5 mm. at apex of 8, 9 and 10 successively a little narrower. Superior appendages 1-6 mm. long, 
slightly longer than segment 9, on the third and fourth fifths is a somewhat sinuous inferior row of 
about ten denticles, inferior margin of appendage beginning to taper to the acute apex at about four- 
fifths of the length. Inferior appendage reaching beyond the last denticle of the superiors, widest near 
mid-length, its apex about one-third as wide as its width at base. Genitalia of segment 2 as shown in 
our figure. 
The distinctive features have been given on page 318, 
Hab. Guatemata, Morales (Hine, O. S. U.: 13); Panama!, Obispo (Hasler Exped., 
M.0.Z.: 16). 
Taken at Morales, March 8, 1905, by Prof. James S. Hine, of Ohio State University, 
to whom this species is dedicated. 
[Rhodopygia hollandi, sp. n. (Tab. IX. fig. 54.) 
Frons, clypeus, and vertex greenish, lips yellowish, in younger males and in females; anterior surface of 
frons, clypeus, and labrum becoming bright red in older males. Thorax and abdomen luteous or greenish, 
the abdominal carine and intersegmental articulations darker, in younger males and in females ; in older 
males the abdomen becomes bright red. Abdomen with a moderately swollen base (segment 2 is 2°5 6, 
3 9 mm. wide), narrowed at segment 4(¢ 1-1-25, 2 1°5 mm.), thence gradually widening to the apex 
of segment 9 (2 6, 2°5 9 mm.). Vulvar lamina projecting about ‘25 mm. from the ventral side of the 
abdomen, with a median semicircular emargination. 
The distinctive features of this species have been given on page 318, 
Hab. Guiana, Demerara (Lugger, coll. P. P. C. ex coll. Uhler: 1 3); Braz, 
Chapada [3 ¢,3 9 +4 ¢, 1 2], Cachoeira [1 ¢ ], Cuyaba [4 g, 1 2] all in Matto 
Grosso (H. H. Smith, Carn. Mus. Pittsb.). 
The examples from Cuyaba were taken at lakes in January, 1886. 
This species is dedicated to Dr. Wm. J. Holland, Director of the Carnegie Museum 
of Pittsburgh, to whom I am indebted for the loan of collections from that Museum. 
This species, especially in the adult male, bears a very considerable resemblance to 
Erythemis hematogastra (Burm.), but it differs in having the labium unmarked with 
black, the abdomen less swollen at base in profile view, the colour at the base of the 
hind wings paler, the pterostigma longer, &c., as well as by the generic characters 
given on pp. 203-4, anted. |
