132 GENUS CERATINOPTERA (oRTHOPTERA) 



Measurements {in millimeters) 



It is evident from this series that the variation in size and in 

 tegmina and wings is due to individual variation and not to 

 geographic distribution. 



General color shining dark chestnut brown to dark russet. 

 Pronotum unicolorous or varying individually as follows; lateral 

 margins sometimes very narrowly to narrowly paler, disk some- 

 times with much suffused tawny markings, these two meso- 

 caudal minute dots varying to a small meso-caudal blotch (see 

 fig. 3), sometimes with the greater mesal portion of the disk in 

 addition very slightly paler than the other portions of the same. 

 Maxillary palpi and limbs ochraceous tawny, usually somewhat 

 suffused. Abdomen of general color, shading mesad both above 

 and below to tawny. 



Immature examples have the head, pronotum, mesonotum and 

 lateral margins of the dorsal abdominal segments, shining chest- 

 nut brown. The pronotum narrowly margined laterad, the 

 entire metanotum and the mesal portion of the dorsum of the 

 abdomen, buffy. Limbs and underparts, not including the 

 head, buffy. 



1' The even numbers given for this dimension are approximated, the speci- 

 mens being in these cases much distorted. 



" A widening in the pronotum caudad, accompanied by a lessening of the 

 convexity of the caudal margin, appears often to accompany reduction in the 

 organs of flight in the lihittidae. Such variation in the pronotum is noticeable, 

 but not pronounced, in the present series.
