Two such freak specimens were found in the collection here in the 

 museum while the writer was working with the Melanopli. The first of 

 these specimens, Melanoplus fcedus, was found to have two distinct 

 median ocelli, both perfect, each about normal in size. The other two 

 ocelli were present as usual, thus giving the grasshopper four perfect 

 ocelli. 



B. M. Blackman found a specimen of femur-rubrum with two median 

 ocelli, and a description and photographs of the same are given in 

 Psyche, vol. 19, pp. 92-97. 



Plate 2, Fig. 4, shows the head and position of the median ocelli of 

 M. fcedus. 



The second specimen, M. bispinosus, shows a great variation in the 

 cerci. The right cercus tapers uniformly from the base toward the tip. 

 is subacuminate, and in no way exteriorly sulcate; while the left cercus 

 tapers from the base toward the middle and then enlarges in the apical 

 half so as to be much wider apically than in the middle; sulcate exte- 

 riorly, so as to be distinctly spatulate. 



Plate 2, Figs. 2 and 3, shows the right and left lateral views of the 

 genitalia of the specimen, which shows the differences in the shape of the
