32 Dr. M. Burr — ]S!otes on the Forficularia. 



Labidura bengalensis, Dolirii. (PI. III. fig. 3.) 



In the squama I see a fourth vein near the base, very 

 short ; no cross- communication. Third vein with faint 

 sector ; inner branch of ulnar very strong. The first and 

 second nervures are joined at the base, the eleventh is 

 looped, as in the two preceding species, but I find two 

 characters in common with the Eudermaptera : namely, the 

 ninth radial nervure has a triangular area, i. e., is strongly 

 angled, and the tenth is 4-shaped, not Y-shaped. 



Eudermaptera. 



LabiidsB. 



Marava wallacei, Dohrn. (PI. IV. fig. 4.) 

 {=gi'cmdis, DuLr.) 



Here the ulnar area is rather broad, the first and second 

 radials are separate at the base ; the ninth is angled, the tenth 

 4-shapetl, but the fourth very narrow and the eleventh has 

 an open loop. 



' Labia annulata (Beauv.). (PI. IV. fig. 5.) 



The wing is rather long and narrow ; the first and second 

 radials are separate at the base ; the ninth is angled, the 

 tenth is Y-shaped, and the eleventh has a closed loop. 



Chatospania australica, Dubr. (PI. IV. fig. 6.) 



The wing is rather narrow ; the first and second radials 

 are separate at the base ; the ninth is angled at the base ; 

 the tenth is 4-shaped, but the 4 is very narrow, and the 

 eleventh is not looped. 



Forficularidae. 



Forficula auricularia, L. (PI. V. fig. 7.) 



To Zacher's observations I will add that the tenth nervure 

 is 4-sliaped, the eleventh simple, and the ninth angled. 

 Tiiat no part is hairy, that the whole wing is short, broader 

 and stronger and darker than in the Prctodermaptera. 



Eparchus insignis, Haan. (PI. V. fig. 8.) 



Scarcely differs from the preceding ; the sector is distinct ; 

 an inner branch to ulnar vein is faintly visible in one 

 specimen.
