186 DERMAPTERA AND ORTHOPTERA FROM SINALOA, MEXICO 



Careful comparison of large series of these species will have to 

 be made before the best diagnostic characters can be tabulated. 

 We are satisfied that distinct species are represented, but so 

 close are they that apparent features of difference between 

 individual series may not be as useful as they seem, when com- 

 parison is made with still other series. 



Stagmomantis limbata (Hahn)

This series shows considerable size and color variation. The 

 majority of the males and all of the females have the cephalic 

 femora immaculate. In the other males these members have 

 three broad, transverse bands of darker shade, which are very 

 decided in the individuals which have head, pronotum and 

 limbs brown instead of green. The males have the tegminal 

 marginal field opaque, usually solid green, sometimes this is 

 narrowly bordered proximad at the mediastine vein with white, 

 while in one brown male the entire field is white tinged with 

 yellowish green, in another brown male it is entirely white. 

 In all the abdomen is immaculate dorsad. The males have, at 

 the stigma of the tegmina, a small blotch of translucent sepia, 

 this reduced to very small size in a few specimens and obsolete 

 in one. In this sex the transparent wings are marked with 

 numerous paired flecks of translucent sepia in the caudal portion 

 of the radiate field. 



The extremes in size are shown !)y the foHowing niensuronients (in niilli- 

 ineters).
