144 PROCEEDINGS OF THE ACADEMY OF [1898. 



I have before me also two males from Madagascar, similar to the 

 one described above, sent to me by M. Martin as basilaris. 



Altogether I think that the probability is that basilaris and Bur- 

 meisteri are color extremes of one and the same species. 



It may be recorded here that in these Glorioso individuals the 

 first pair of legs are blackish like the others, that the genital ham- 

 ule of the male projects beyond the genital lobe, that the inferior 

 appendage of the male is half as long as the superiors and reaches to 

 the last denticle thereof, the superiors being longer than 9+10 but 

 shorter than 8+9+10, and that the vulvar lamina of the female is 

 three-fourths as long as 9, bilobed in its own apical three-fourths, 

 and her appendages as long as 9+10. 



This species has not been recorded from the Seychelles. 



4. Tramea continentalis Selys. 



Selys, Mitth. Dresdner Mus., Hi, p. 299, 1878. Martin, Mem. Soc. Zool. 

 France, 1896, p. 102. 



One male, one female, Mahe Is., Seychelles. 



The male is the same form so identified by M. Martin as he has 

 sent me one of his Seychelle specimens. The female is like those 

 he mentions in his last sentence (J. c.) "Certaines femelles n'ont 

 menie qu'une petite tache marron tres courte, le long de la mera- 

 branule et le surplus de la tache normale est indique' par une teinte 

 jaune brule tr&s clair, presque limpide." A male in my collection 

 from West Madagascar by Hildebrandt, formerly in the Museum 

 fur Naturkunde, Berlin, where it stood as T. limbata is of the same 

 species and Mr. Kirby's description of Tramea madagasearensis 

 (Trans. Zool. Soc, London, XII, p. 317, 1889) also applies here. 

 Unfortunately even M. Martin does not give a sufficiently full state- 

 ment of the distinctions between limbata Desjardins and continentalis 

 Selys, and it is not certain that the insect I have described as T. 

 limbata (Proc. U. S. Nat. Mus. xviii, p. 121 ; Ent. Nachr. xxii, p. 

 217, 1896) really is such. 



In these two continentalis — the male has the hamule projecting 

 •considerably beyond the genital lohe, the superior appendages are 

 almost as long as 8+9+10, the inferior appendage is almost half as 

 long as the superiors and reaches slightly beyond their denticles ; 

 the female has the vulvar lamina seven-eighths as long as 9, bilobed 

 in its apical three-fourths, the appendages as long as 9+10.
