In size the type represents what is the average of the entire male 

 paratypic series, practically none but the extremes measured above 

 varying appreciably from the more general size. The allotype is in 

 most measurements the maximum extreme for the female sex, from 

 which the series grades rather evenly to the minimum measurements 

 given for that sex. The length of the body is an uncertain measure- 

 ment, as it depends so largely on the stuffing of the abdomen, and, 

 while the present series was stuffed in its entirety by the authors, 

 -a certain amount of variation in bulk is impossible to prevent. The 

 length of the cephalic femora, particularly in the female sex, shows 

 appreciable variation — in females of approximately the same bulk 

 measuring 7.8 and 9.2 mm. This variation is also noticed in the 

 median femora, while the tibiae of the respective limbs vary propor- 

 tionately. Such variation in the length of the caudal femora as is 

 evident is of a far less degree and not disproportionate to the general 

 bulk variation. The tegmina of the male show some variation in 

 .length, never being shorter than the pronotal length, but occasionally 

 surpassing the same. 



Color Xotes — The general pattern of the male sex consists of a 

 dorsal shade covering the dorsum of the head, disk of the pronotum; 

 another covering the tegmina (aside from the marginal field and 

 region of the principal veins) ; a paler lateral color involving the face, 

 sides of head, lateral lobes of the pronotum, and sides of the abdomen; 

 an area covering the dorsal surface of the abdomen either concolorous 

 with or darker than the dorsal shade of head, pronotum and tegmina, 

 and a pair of pale, narrow postocular lines extending along the angle 



" Owing to the poor definition of the dorsum of the pi'onotum in the female, 

 this measurement is of less value than in the male, but it is here given to cover 

 .relatively the same portion as that measured in the other sex.
