188 THE CANADIAN ENTOMOLOGIST. 



Stal puts it. On superficial cliaracters for easy identification, they may be" 



separated as follows : 



With broad anterior femora. 



With a blunt tooth near the tibial joint R. qundridentata, Stal, 



Without a blunt tooth near the tibial joint. . R. Kirkaldyi^ n. sp. 



With narrow anterior femora, smooth, save for the middle 



tooth R. fusca, Pal. Beauv. 



R. Kirkaldyi can at once be distinguished from both fusca and 

 quadridentata by its smaller size, being little over two-thirds the length of 

 either of them ; short and much constricted prothorax, and very short 

 air-tubes. R. fusca can be further differentiated from quadridentata by 

 the much longer legs, the tarsal claws reaching nearly to the extremity of 

 the air-tube, and the extremities of the femora of the third pair of legs 

 attaining to the end of the penultimate abdominal segment ; by the 

 prominent eyes ; and by the prothorax being slimmer and longer and 

 unisulcate beneath ; while in R. quadridentata the legs are not unduly 

 long, the tarsal claws of the third pair barely going beyond the middle of 

 the air-tube, and the extremity of the femora going but little beyond the 

 anterior margin of the penultimate abdominal segment ; the eyes moder- 

 ately large ; and the prothorax more stoutly built and bisulcate beneath. 



As R. Kirkaldyi is still undescribed, I briefly give its salient 

 characters, prior to a full description to be published later. 



Ranatra Kirkaldyi, n. sp. — Abdominis dorsum orange brown ; eyes 

 small, not very prominent ; prothorax much constricted at the middle, 

 bisulcate beneath; wings smoky; anterior femora broad, with a prominent 

 tooth near the middle, otherwise smooth; posterior tarsi extending beyond 

 the middle of the air-tube; air-tube shorter than the length of the abdomen; 

 legs banded. 



Length from end of abdomen to tip of rostrum : Males 23 mm. to 

 26.4 mm., females 27 to 31 mm.
