dish yellow margins to the segments. Often, especially in minor workers, the 

 pale color is more extensive and the whole insect may be ferruginous i-ed with 

 brownish black gaster." 



As I possess only a few small workers (cotypes from Mr. Pergande) 

 of this species, I have translated Emery's original description. 



49. C. hyatti Emery var. bakeri Wheeler 

 Wheeler, Bull. Amer. Mus. Nat. Hist, XX, p. 271, ^ ? , 1904. 



Worker media. Length, 5.5 mm. 



Differing from the typical form in coloration, which is like that of C. fallax 

 var. discolor, except that the basal two-thirds of the first gastric segment are 

 red, like the head, thorax and appendages. The sculpture is quite as sharp as 

 in fallax, and the surfaces of the head and body are quite opaque. The man- 

 dibles and cheeks are coarsely punctate. In profile, the thorax is like that of 

 the typical hyatti, except that the basal surface of the epinotum has a trans- 

 verse impression behind. 



Female. Length, 7.5-S mm. 



Resembling the female of C. fallax var. discolor. Head longer than broad, 

 with nearly straight posterior border and prominent posterior angles; cheeks 

 converging in front, distinctly concave. Mandibles 5-toothed. Whole body 

 more shining than in discolor, though it is throughout distinctly shagreened. 

 Mandibles, cheeks and front coarsely punctate. Body and appendages yellow- 

 ish red, teeth of mandibles, anterior border of cheeks and clypeus, scutellum, 

 metanotum, a narrow band across the posterior iwrtions of the first and 

 second gastric segments and the remainder of the gaster, black. Posterior 

 edges of all the gastric segments yellow. There is a more or less distinct 

 brown cloud on the anteromedian and in one specimen also on the lateral sur- 

 face of the mesonotum. Wings yellowish gray, with brownish yellow veins. 



Described from two mediae and two female specimens taken by Prof, 

 d. F. Baker on Catalina Island, California. 



V. Senex Group 

 50. Camponotus mina zuni subsp. nov. 



Worker major. Length, 6.5-7 mm. 



Head rather small, subrectangular, a little longer than broad and a little 

 broader behind than in front, with slightly excised posterior and feebly convex 

 lateral borders. Eyes rather large, slightly convex. Mandibles 5-toothed, with 

 convex external borders and upper surfaces. Clypeus distinctly carinate. very 

 slightly produced anteriorly as a broadly rounded lobe, with a faint median 

 sinus. Frontal area distinct, triangular, as long as broad. Frontal carinse 

 strongly lyrate, approximated anteriorly, twice as far apart behind as in 

 front. Frontal groove distinct. Antennje short ; scapes slender and terete at 

 the base, somewhat enlarged towards their tips, which do not extend beyond
