GENUS CARIBLATTA (oRTHOPTERA) 



distal in position; individual variation is so great that in specific 

 diagnoses this feature is best omitted. The same is true for the 

 axillary vein; in addition to a number of the free veins of the 

 axillary field, which frequently spring from this vein near its base, 

 it is found to have three, very rarely four, rami; the rami spring 

 from the vein normally caudad, very rarely cephalad and some- 

 times both divisions of the rami diverge equally, or one of the 

 rami itself again divides.

The genus divides into three distinct groups, of which the first 

 and second may be termed the West Indian complex and the 

 third the South American. The West Indian complex, excepting 

 the single species of group two, shows the ulnar vein of the wings 

 with but one or two conspicuous rami, though other rami may 

 occur distad; all have more or less distinctive features of color- 

 ation; reticulosa, punctulata, craticula and insularis are the more 

 slender forms. The second group includes the single species, 

 insularis; distinctive in general appearance, in the unusual pro- 

 notal marking, in the tegminal markings and in the remarkable 

 male genitalia. The ulnar vein of the wings has more than one 

 or two conspicuous rami. The South American forms, excepting 

 fossicauda, have the ulnar vein of the wings with several rami; 

 all are inconspicuously colored; none are as slender as punctulata.
