PLATE XLIX. 



(All photographs natural size.) 



Photo 1. Photograph of Palisot's figure of Ranatra jusca, reproduced exact 

 size. 



Photo 2. Ranatra kirkaldyi Bueno. Largest specimen in a long series. 

 A female from Cherokee county, Kansas, determined by Mr. J. R. de la 

 Torre Bueno. This is what Doctor Montandon has mistaken for Ranatra jusca 

 P. B. Besides size, note shape of front femur. Not constricted as it is in 

 figure 1. 



Photo 3. Ranatra jusca P.B. (= R. americana Montd.) Note the general 

 resemblance to original figure by Palisot (photo 1 above), the shape of the 

 thorax, the broad anterior femora, the size of the insect, the reduced hind 

 femora, etc. For other figures of this insect, see plate LI, photographs 3 and 7. 

 Figure 7 is the only one to show the apical tooth of the front femur plainly. 

 The writer has forms with the respiratory tube of various lengths. The short- 

 est perfectly formed tube is shown on plate LI, figure 3. 



Photo 4. Ranatra kirkaldye Bueno var. hojjmanni, var. new. 



Photo 5. Ranatra bitenoi, sp. new {=R. jusca Bueno). Compare with 

 Palisot's R. jusca (photo 1). The relative proportions of the front femora, the 

 length and shape of thorax, limbs and filaments. The long tibise and reduced 

 tarsi. This photograph is of a paratype.
