ute crowded spines directed downward which all have 

 upon either edge of the under-side, have also five spines 

 of a peculiar character placed in each of these rows ; they 

 are quite long, placed at regular distances from one 

 another, from the tip of the tibiae to near its base, those 

 upon either row alternating with one another, and directed 

 in almost exactly opposite directions ; they do not point 

 backwards at the same angle with the others, but are turned 

 outwards nearly at right angles to the tibise ; the tibiae of 

 the other legs also partake of this character to some extent ; 

 in this species the spines of the posterior femora are 

 altogether wanting in the female, while the male has 

 spines similar to those of C. Uhleri. Antennae quite 

 long ; hind femora in male stouter than in female. 



Length of body, .45-.60 in.; hind femora, .25-.30 in. ; 

 antennae, 1.5-2 inches. 1 < 2 9.

7. C. LATENS, nov. sp. 



Pale yellowish brown, with darker streaks upon the 

 hind femora and two broad bands of dark reddish brown 

 along the whole dorsum, extending half-way down the 

 sides, dotted irregularly with brownish yellow spots most 

 profusely on the abdomen, and separated from one an- 

 other by a narrow, irregular band of the same color ; head 

 above, reddish brown ; below, yellowish brown ; tips of 

 the femora dark ; no spines upon the under-side of the 

 hind femora. The hind femora are thick and stout, and 

 the whole hind leg shorter than in most of the species. 

 The ovipositor is shorter than usual in this species, though 

 not nearly so short as in C. californianus. 



Length of body, .65 in. ; of hind femora, .5 in. ; of 

 ovipositor, .27 in. 1 9 (antennae broken).
