Libellula angustipennis Ttamb. 



One teneral female taken by me seems to agree with the descriptions 

 by Selys and Hagen, although my specimen is somewhat smaller. 



When living, this teneral 9 showed the vertex of the head next the 

 eyes very dark reddish-brown ; the rest of the vertex and the upper 

 part of the face steel-blue with metallic reflections, below lemon-yel- 

 low ; the dorsum of the thorax dark yellowish-brown, the pleura steel- 

 blue, both with some metallic reflections, and their stripes (which on the 

 dorsum are a median and humeral line, and on the pleura are two lines 

 and two stripes alternately disposed, the stripes (posterior) lemon- 

 yellow; abdomen of a lighter yellowish-brown than the dorsum of the 

 thorax, the basal streaks lemon-yellow, and the edges black. 



Antecubitals, 14-15 ; postcubitals, 8-9. Expanse of wings, 2.4 inches; 

 pterostigma, .13 inches. 1 teneral ?. 



Libellula vinosa nov. sp. 



Front reddish-brown, paler in the middle (the labrum sometimes 

 edged with black), or dull olivaceous-yellow (in life deep blood-red); 

 dorsum of thorax fuscous (in life olivaceous-red) obscurely banded 

 before the humerus with dull yellowish (in life only a lighter tint of the 

 basal color) or with a median line and two narrow (the anterior some- 

 times broad) humeral stripes, bent abruptly, without widening, at the 

 humerus, and just falling to reach the middle line, yellow; pleura fus- 

 cous, sometimes with slight steel-blue reflections (in life dark olivaceous- 

 brown with dark greenish reflections) with four yellow or ochraceous 

 stripes (in life blood-red * ) ; the anterior irregular, indistinct close 

 to the humeral stripe ; the second in the middle, broad and straight, 

 the fourth as broad as the second, bordering the hinder edge of the 

 pleura, the third between them insignificant and irregular ; wings 

 hyahne with vinous veins, sublnfuscated at tip, the anterior pair fla- 

 vescent from tlie base to about one-third the distance to the triangle ; 

 posterior pair fusco-flavescent at the base as far as the triangle, with 

 two blackish streaks In the spot, between the second and third and the 

 fourth and fifth principal veins, which are also indistinctly seen on the 

 anterior wings ; pterostigma nigro- (teneral) or rubro-fuscous ; mem- 

 branule blackish ; legs black, base of femora, inside of fore and some- 

 times middle femora luteous ; abdomen reddish-broAvn (in life blood- 

 red or yellowish-brown, teneral) ; the incisures, segments 1-4 and 8-9 



* This deep and brilliant color in this and other parts is mentioned in my notes 

 only with reference to the darker colored and banded individuals ; I can hardly be- 

 lieve that those wliich have the bands distinctly and rather fresh yellow at present, 

 could have had them blood-red during life; it does not appear to have any teneral 

 siifnilication.
