39. Camponotus pellarius new species. 



Worker major. — Length 7.5-8 nun. 



Superficially resembling C. chileitsis Spinola in color, sculpture and pilosity. 

 Head, excluding the mandibles, as broad as long, broader behind than in front, 

 with straight sides and very feebly concave posterior border. Mandibles rather 

 small, convex, with 6 subequal teeth. Clypeus flattened, feebly carinate, with 

 straight, entire anterior border. Frontal area distinct, broadly triangular. 

 Frontal carinae sigmoidal, diverging behind. Eyes moderately large and con- 

 vex. Antennal scapes distinctly flattened at the base, enlarged at their tips, 

 which extend somewhat beyond the posterior corners of the head. Thorax 

 short, rapidly contracted posteriorly, pronotum flattened above, rather broad, 

 with its sides in front distinctly and rather sharply marginate; in profile the 

 outline of the thorax is evenly convex and rounded, the epinotum continuing 

 the curve as this region is uniformly sloping and without distinct base and 

 declivity. Promesonotal suture very distinct ; mesoepinotal suture obsolete, 

 but indicated by an impression on the pleurae. Petiole nearly as high as the 

 epinotum, compressed anteroposteriorly, with slightly convex anterior and flat 

 posterior surface and blunt, entire, broadly rounded superior border. Gaster 

 rather large, flattened above. Legs moderately long. 



Mandibles shining, sparsely punctate ; anterior border of clypeus coarsely 

 punctate, remainder of body, including the antennse and legs opaque, densely 

 punctate. 



Hairs rather stout, blunt, snow-white, erect, abundant, moderately long on 

 the body, fore coxae and lower surfaces of the femora, much shorter and more 

 appressed on the remainder of the legs. Anterior clypeal border with a row of 

 golden yellow bristles. Pubescence on the head, thorax and scapes white, 

 sparse and conspicuous, especially on the head ; on the dorsal surface of the 

 gaster brilliant golden yellow, and so long and dense as to cover the surface 

 completely. 



Whole body black, except the strigils of the fore tibiae, which are deep red. 



Worker minor. — Length 5-6.5 mm. 



Differing from the major worker only in the smaller size and proportion- 

 ally smaller and narrower head. 



Described from numerous workers taken from a single colony, 

 which was nesting in the crevice of a large rock at San Miguel. This 

 species differs from cliilcnsis in having the pronotum marginate on 

 the sides, broader and more flattened above, the clypeus indistinctly 

 instead of strongly carinate and in the pilosity, which is much more 

 abundant, coarser and snow white. The golden pubescence on the 

 gaster is also much more brilliant. That pellarius may eventually
