50 PROCEEDINGS OF THE ACADEMY OF [Feb., 



antennse pale proximad, dark distad. Pronotum with the continua- 

 tion of the postocular bar solid, deep seal brown in the male, slightly 

 weaker in the female, extending across the whole of the lateral lobes 

 and in depth being nearly half that of the same, the ventral line being 

 more definite mesad than cephalad and caudad ; ventral portion of the 

 lateral lobes pale russet. Dorsum of the mesonotum and metanotum 

 similar to the dorsum of the pronotum, metathoracic epimera dorsad 

 to the line of the dorsal margin of the tegmina and the mesothoracic 

 epimera shining seal brown, episterna russet. Tegmina with a dorsal 

 section russet (paler in the male) ; ventral section shining seal brown. 

 Abdomen of the lighter general color with longitudinal series of con- 

 tiguous seal brown blotches on the dorsal section laterad of the median 

 line, w^hich is a very striking pale bar, these blotches varying in inten- 

 sity in the sexes (stronger in the male) and in individuals ; apex of the 

 male abdomen and the ventral surface of the same touched with orange 

 rufous. Cephalic and median limbs brownish touched with olive green ; 

 caudal femora vandyke brown dorsad, the dorsal half of the paginal 

 area blackish brown, ventral half and ventral sulcus cream color 

 washed slightly with greenish, genicular lobes pinkish buff touched with 

 scarlet vermilion; caudal tibiae and tarsi scarlet vermilion, the spines 

 tipped with black. 



Measurements. 



Length of body, 21 mm. 



Length of pronotum, 5 " 



Cephalic wddth of disk of pronotum, ... 2.7 " 



Caudal width of disk of pronotum, .... 4.2 " 



Length of tegmen, 4.3

In addition to the types a series of six males and seven females of 

 this species have been examined, all of which except one pair from 

 Palmerlee (in coitu; August 7, 1905; Schaeffer) are paratypic (Septem- 

 ber 23 and 24). In size but little variation is presented, and in color 

 such as exists is chiefly in the depth of the coloration , the two extremes, 

 both females, one with russet predominating and the other with seal 

 brown the prevailing color, can readily be given their proper associa- 

 tion, as the distinctive color pattern is essentially the same. In some 

 specimens there is a tendency to breaking in the pronotal continuation 

 of the postocular bar, but in no case is this as complete and strongly 

 defined as in C. neomexicana.
