female of the Hawaiian species, of which that sex is always wingless. 

 But the structure of the uieso- and metanota of the male of the latter 

 and the mode of the attachment of the wings, make it very doubtful 

 whether the two species could be placed in the same genus. I imagine 

 Oligotoma insularis to be a highly abnormal species. In the book 

 mentioned above we read (/. c, p. 352), "When they" (Embiidcs) 

 " bear wings,* there is no modification or comhi7iation of the segments 

 for the purposes of fight, the condition of these parts heing, even then, 

 that of iniiigless insects : so that the Embiidce that have wings may be 

 described as apterous-like insects provided with two pairs of inefficient 

 wings." From the great difference between the meso- and metanota 

 of the (^ and ? of the Hawaiian species, it is evident that the simple 

 structure of the latter sex is not always present in the former. The 

 more complicated structure of these parts in the (^ appears partly at 

 least for the purpose of packing the wings flatly on the back and se- 

 curing them so, for it is almost as difficult to extend these as the wings 

 of ForfcuJa. 



In one group of specimens captured I found a (^ with only the 

 stumps of the wings remaining. It is probable, however, that this 

 had been caused by some predatory creature, and not that they had 

 been voluntarily removed.
