Doctor Calvert has made the following notes on living Costa Rica 



material : 



Male: Eyes bright red in uppermost third, brown in middle third, pale green in 

 lowermost third, these three colors marked off distinctly from one another in horizontal 

 bands; one black pseudopupilla visible in each band, but less distinctly in the 

 brown. Body colors red, black, and yellow, the last as a transverse median line on 

 irons, a narrow margin to the free edge of the labrum, genae, labium, most of meta- 

 pleura, pectus, legs, sides, and ventral surface of segment 1, and ventral edges of 

 tergites of 2-9. Female: Eyes colored as in the male but the red less bright and less 

 extensive; no red on the rest of the body, which is dark brown (thorax) and black 

 (abdomen) , marked with yellow. This species flew along the banks, close to the water, 

 where it was shallow and not very swift. The male and female flew together, the male 

 holding the female, which oviposited in submerged leaves fallen from the trees 

 overhead. 



The variation in the extent of red on the mesepisternum of the 

 male is very great and is apparently independent of locality, Doctor 

 Calvert's material from one locality in Costa Rica showing all varia- 

 tions. In the darkest phase the antehumeral red area at its widest 

 point is less than half as wide as the black area lying between it and 

 the middorsal carina, and is separated from the antealar red spots by 

 a distance about equal to the width of the mesepisternum. Three of 

 Doctor Calvert's 21 males show this pattern. Thirteen males are about 

 the pattern shown in figure 15 (pi. 43.) Five have the antehumeral 

 and antealar red joined, in two cases the red constricted at the point 

 of joining, while in the remaining three this point is entirely obliter- 

 ated, the broad red antehumeral stripe extending from the wings to 

 and onto the prothorax, completely isolating the oval-shaped mid- 

 dorsal black, which, on either side of the middorsal carina, occupies 

 an area on the mesepisternum about equal to the red. The speci- 

 mens from Trinidad are colored like the 13 Costa Rica males. 



PROTONEURA CUPIDA Calvert. 



Los Amates, Guatemala, June 19, 1909, 1 male, along Rio San 

 Francisco, a small stream 10 to 20 feet wide. 



PROTONEURA CARA Calvert. 



Agua Caliente, Department of Santa Rosa, Guatemala, June 2, 

 1909, 2 teneral males; Gualan, Guatemala, June 14, 1909, 1 male. 



PROTONEURA AURANTIACA Selys. 



Los Amates, Guatemala, June 21, 1909, 5 males, 1 female, along a 

 small wet-weather stream in woods. One of the male specimens is 

 deposited in the United States National Museum. 



Some doubt existed as to the identification of aurantiaca, 1 so a 

 male was sent to Monsieur Severin for comparison with the De Selys 

 material. Doctor Ris reported as follows : 



There are in the Selys collection two specimens under this label: (1) Bears a label 

 with aurantiaca canceled and crocea written in Selys' s hand, and a second label with 

 paucinervis alone. This specimen is clearly different from Mr. Williamson's specimen
