| have no information as to the habits in life of this species, 
but I imagine that it, like the allied species of Derocalymma, 
is found under stones. This mode of life in numerous cases 
induces a flattened form with reduction of the tegmina; the 
broadening and flattening of the body may be observed, 
though to a less extent, in such species as Lemnopterye 
phalerata, Sauss., and Heminaupheta sakalava, Sauss. «& 
Zehntn, 3 in these species also the tegmina are reduced and 
quadrate, and the constriction of the body in the middle has 
also occurred to a certain extent, and one may assume that 
it is correlated with the broadening of the reduced tegmina.
