Iliad formerly mistaken this species for Cal. occidentalls 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. PACK AH 1)11 SERIES. 



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

 or subquadrate, and the interval between the mesothoracic h)bes 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 collinus series. The furcula is 

 slightly developed, consisting of moderately slender denticu-lations, not 

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

 ately broad, gently si)atulate, the apical portion generally inbent, 

 sometimes merely incurved, often externally sulcate. The subgenital 

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

 narrowed, the a])ical margin neither elevated nor x^rolonged, 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
