^6 THE BLATTIDAE OF PANAMA 



very faintly paler brown, the three joints preceding the last joint white. In the 

 instar eleven millimeters in length they have twenty-nine joints of which the 

 thirteenth to the fifteenth are very faintly paler brown, the three joints preced- 

 ing the last joint white. In the instar eight millimeters in length they, have 

 twenty-four joints of which the tenth to the twelfth and the three joints preceding 

 the last joint are white. 



In all the arolia are of the same proportions as in the adult. 



In addition to the type, the following series of immature ex- 

 amples is at hand.

The Cuban material, originally included, and the South American 

 material, later included by Saussure, represent distinct though 

 allied species, described by Saussure and Zehntner in the Biologia 

 Centrali-Americana.

The present series shows but a moderate amount of variation. 

 The three males from Paraiso are recessive in coloration, the 

 pronotal picturing being cinnamon brown with chestnut flecks, 

 rather than blackish chestnut brown as is usual. In such speci- 

 mens the dark line and flecks along the humeral vein of the 

 tegmina are also decidedly reduced and weakened. Additional 

 material at hand, however, shows that this is by no means t he- 

 extreme of recessive coloration attained in the si)ecies.
