well rounded, subspatulate, and exteriorly broadly sulcate or depressed, 

 reaching only the break in the lateral margin of the supraanal plate; 

 infracercal plates extending laterally distinctly beyond the cerci, and 

 apically to the tip of the supraanal plate; subgenital plate pretty regu- 

 larly scoop- shaped, scarcely flaring, the apical margin almost entire, or 

 emarginate only by a feeble lateral elevation of the margin as seen from 

 behind.

I had formerly mistaken this species for Cal. occidentalis Thomas, and 

 distributed specimens under that name. This note may serve to correct 

 the error. The longer furcula serves somewhat readily to distinguish 

 this species from the preceding, smaller and less heavily maculate 

 species. 



22. PACKARDII SERIES. 



This is a group in which the prozona of the male is usually quadrate 

 or subquadrate, and the interval between the mesothoracic lobes of the 

 same sex varies from quadrate to fully twice as long as broad. The 

 prosternal spine is usually rather short, often appressed. The tegmina 

 are always fully developed and reach or surpass a little the tips of the 

 hind femora; the hind tibiae are generally red, sometimes blue, and 

 have nine to twelve spines in the outer series. 



The supraanal plate is as in the colliuus series. The furcula is 

 slightly developed, consisting of moderately slender deuticu-latious, not 

 longer than the last dorsal segment. The cerci are generally moder- 

 ately broad, gently spatulate, the apical portion generally inbent, 

 sometimes merely incurved, often externally snlcate. The subgenital 

 plate is never very broad, ordinarily rather narrow, subequal or apically 

 narrowed, the apical margin neither elevated nor prolonged, and gen- 

 erally well rounded and entire. 



The five species are of rather large or medium size, and comprise 

 two tolerably distinct sets: one, of two species, of ordinary form, with 

 short, apically truncate cerci, not nearly attaining the tip of the supra- 

 anal plate, and with strongly divergent forks to the furcula; and a 

 second, of three species, of very robust form, cerci which though short
