of caudal tibi?e five in number, rarely six (in apparent rigidity, more 

 closely approaching Grylhis than any other species of the present 

 genus) ; the six distal spurs are also heavy. 



A megacephalic condition similar to that found in Uucatus, under 

 which species we have discussed this feature, is also found in ver- 

 ticalis. 



Of the material discussed above, the male from Igarape Assu, 

 Brazil, is macropterous, length of wing 19.9 mm., and also the females 

 also from Cordoba, Mexico, length of wing 18.1-19.4 mm. 



These series show a decided individual size variability with, how- 

 ever, little variation in proportions. A great amount of size varia- 

 tion appears to be due chiefly to local environmental conditions, but 

 from our material the species does appear to average distinctly 

 larger in temperate South America than in the United States; in 

 the latter country no geographic size variation appears to exist, ex- 

 tremes being found almost indiscriminately. 



From Nebraska to the Gulf coast of Texas, the extreme intensive 

 type of coloration, in which particularly the males are almost uniform 

 black (described as oklaJionicc) , is very frequently encountered; this 

 type of coloration also appears occasionally in Georgia and Florida, 

 but further north on the Atlantic coast this condition has not been 

 found. Every conceivable intergradation between this and the normal 

 type of coloration is found over the entire range of the species. 



The most northern point at which the species has been found is 

 Staten Island, New York. The material before us defines the further 

 known distribution of the species, with the exception of a record from 

 Paraguay by Giglio-Tos as " G[7'yllodcs] saussurei," and specimens 

 recorded by that author as both La Plater and guycnncnsis from Co- 

 lonia Risso, Rio Apa, Paraguay, and under the last name from Villa 

 Rica, Paraguay.
