A NEW GENUS, CARIBLATTA, OF THE GROUP BLAT- 

 TELLITES (ORTHOPTERA, BLATTIDAE) 



BY MORGAN HEBARD 



Among the various well defined groups formerly treated under 

 the generic name Phyllodromia Serville, {Blattella Caudell sens, 

 lat.), we find one clearly marked, composed of diminutive species 

 occurring in the West Indies, Trinidad, Panama and the south- 

 eastern United States. Certain of the species have been de- 

 scribed under the generic name Blatta, these being later referred 

 to Phyllodromia, as has been one synonymous name originally 

 placed in Theganopteryx (Pseudectohia), while still another was 

 described as, and has for quite a few years been erroneously con- 

 sidered, a member of the genus Ceratinoptera. 



So little constructive work had been done in the classification of 

 the group Blattellites, that the true relationship of these species 

 only became apparent to us when extensive collections from the 

 West Indies and Trinidad came into our hands for study. 



With the material now in hand, we are able to assign this group, 

 which we find it necessary to describe as a new genus, to its 

 proper position, and we are also obliged to describe six species 

 and one geographic race which were previously unknown or 

 unrecognized. 



CARIBLATTA 1 new genus 



Genotype.— CanfcZa^^a punciulata [Blatta punctulata] (Bcau- 

 vois) . 



This genus is a member of the group Blattellites, there forming 

 one of the groups of species to which Shelford has hastily applied 



^ This name is chosen since the greater number of the fornis of the present 

 complex would appear to be found in the regions in which the Carib Indiana 

 were native.
