no. 2089. NOTES ON NEOTROPICAL DRAOONFLIE 8— WILLIAMSON, 62 5 



aurantiaca from Los Amates. (2) P. aurantiaca, Panama, 2 green labels; this speci- 

 men is certainly Mr. Williamson's species, though having the black bands of the 

 thorax somewhat narrower; the appendages are the same. 



The female of aurantiaca, not previously known, is described below. 



Length of abdomen, female, 27 mm.; hind wing, female, 18 mm. 



Head similar to male, with the following exceptions : Pale areas in 

 front slightly more extensive, the labrum with the lower third pale, 

 not entirely black as in the male. The geminate orange spot on the 

 dorsum of the frons at its anterior edge in the male is entirely wanting 

 in the female. Thoracic markings similar in the two sexes, but the 

 dark markings more extensive in the female; especially true of the 

 middorsal stripe, which is about twice as wide as in the male. In the 

 female, as might be expected, the pale colors are less brilliant, espe- 

 cially on the lower part of the thorax and the legs. No mesostigmal 

 spine. 



Abdomen black above, a narrow basal ring on 3; 1-7 with sides 

 above dark and lower half pale; 3 and 4 apically encircled with dark; 

 8 and 9 each with a lateral pale spot; 10 black. Genital valves 

 reaching the end of 10, the long slender palpi exceeding the conical 

 short appendages which are shorter than 10. 



PROTONEURA CAPILLARIS Rambur. 



This, the type of Protoneura, is found only in Cuba, where no other 

 species of the genus are known to occur; mesepisternum and mese- 

 pimeron (the latter not entirely in the young) black or violet-black ; 

 male abdomen with segment 3 about five times as long as 2, and the 

 basal fourth dorsally blue; 4-6 with pale basal rings; 7 blue with an 

 apical brown ring; 8-10 black, a little yellow on the sides; female ab- 

 domen bronze black, 3-7 with pale basal rings and larger black apical 

 rings; abdomen, male 30-30.5 mm., female 25-26 mm.; hind wing, 

 male 16.5-17 mm., female 17.5-18.5 mm. 



In the key to genera and species capillaris will fall in h 2 under a 1 . 

 It may be separated at once from the Central American species falling 

 under the same section by the unmarked black or violet-black mese- 

 pisternum. 



I am indebted to Doctor Calvert for the loan of the left front and 

 hind wings of a male from Cuba, collected by C. L. Wright, in the 

 Academy of Natural Sciences of Philadelphia. Doctor Calvert also 

 sent me a sketch of the basal parts of the right wings of the same 

 specimen. 



EPIPLEONEURA LAMINA, new species. 



Length of abdomen, male 29-31 mm., female 26.5; hind wing, male 

 18-r9 mm., female 18. 



Head. — Male and female. Black above with green reflections; 

 labium pale flesh; lower third of labrum dull pale yellow; anteclypeus 

 and frons below in front light yellow, continuous with the genae,
