PLATE L. 



. (All photographs natural size.) 



Photo 1. Ranatra australis, sp. new. Differs from R. jusca P.B. by shape 

 of jirothorax. longer respiratory tube, lack of apical tooth on front femora 

 and by its elevated jugse, as well as marked differences in the genital claspers 

 of the male. Southern in distribution. Photograph from paratype. 



Photo 2. Ranatra nigra H. S. (= R. protcnsa Montd.) This insect in a long 

 series fits the original description most remarkably, except for the color, which 

 is of no consequence at all; "Size 2-2 Vs inches from beak to tip of filaments. 

 Filaments % inch long; limbs long and slender." Photo 5 is another speci- 

 men — the latter from Minnesota, the former from Kansas. 



Photo 3. Ranatra brevicollis Montd. From California. Note the short, 

 broad thorax and its relation to the size of the head. 



Photo 4. Ranatra drakei, sp. new. Slender front femora with apical tooth, 

 large eyes, long thorax, long limbs, and Aery long respiratory filaments.
