354 STUDIES IN THE ISCHNOPTERITES (oRTHOPTERA) 



spicuously darker than the remaining portions of the face (as is 

 normal in ruja rufa). A few unusually dark specimens before 

 US have the pronotum blackish chestnut, shading to morocco 

 red meso-cephalad (Santa Ana and San Jose, Costa Rica) . Three 

 specimens (Pozo Azul, Costa Rica) are not only very large and 

 robust, but are dark in general coloration with pronotum deep 

 bay, in one of these strongly and in one weakly but broadly mar- 

 gined cephalad and even more broadly laterad with tawny, and 

 with the marginal field of the tegmina in all ochraceous buff. 

 These specimens would at first glance appear widely distinct 

 from rufa occidentalis, but careful examination of the series 

 clearly shows that they represent no more than the maximum 

 intensive coloration in the series before us, accompanied by very 

 decided size development. Decided differences in size, tegminal 

 and wing development, with or without such variation in color, 

 is found throughout the present inextensive series.

23 This specimen and the type described from New Orleans, Louisiana, are 

 the only records of the species from north of Vera Cruz, Mexico. Rather 

 extensive study and field work along the Gulf coast in the United States, leads 

 us to be strongly of the opinion that these two northern records are based on 

 adventive, rather than indigenous, material. 



" One specimen labelled "Mexico", has been recorded by Rehn as the syn- 

 onymous /. consobrina. 



^ These specimens were presented to the Academy by Saussure, who labelled 

 them /. consobrina.
