1 have no information as to the habits in life of this species, 

 but I imagine that it, like the allied species of Derocalijmma, 

 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 Temnopteryx 

 phalerata, Sauss., and Heminauphceta sakalava, Sauss. & 

 Zehntn. ; 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.
