of the abdomen, where it is clear red. Wings rather dilute 

 fuliginous, violaceous. 



Hah Pachacayo, Peru, over 12,003 ft., March 27 (C. H. 

 T. Toivnsend). 



A species of the same general type as C. kcemorrkoidalis 

 (Fab.), but more robust, with the wings darker and the 

 abdomen less blue. Superficially, it is exactly like the 

 workers of Bombus coccineus, Friese, which were taken by 

 Piofessor Townsend at the same time and place. 



Bombus rufocinctus alhertensis (Cockerell). 



The following notes, additional to the original description, 

 are taken from the type. Pile coarse, rather long, on 

 abdomen much shorter than in B. kirbyellus ; ocelli about as 

 in rufocinctus, as also the deep sulcus in front of middle 

 ocellus ; corbicular fringe pure black ; spinules of tarsal 

 joints red : black interalar band eye-shaped, narrowing 

 laterally. The following measurements are in microns : — 

 antero-posterior diameter of middle ocellus 357 ; transverse 

 diameter of a lateral ocellus 3.23; lateral ocellus distant 

 from eye 595 ; middle ocellus to lateral oeellns 221 ; length 

 of third antennal joint 595, of fourth 323, of filth 357.

General colour of upperside olive-green, owing to the pale 

 yellow anuulation of the black hairs. Dorsally the pale 

 annuli are narrower than laterally, making the sides of the 

 body lighter than the back. Ventrally the yellow annuli 

 prevail over the black, so that the sides of the belly are pale 

 yellow. Along the middle line of the belly there is a narrow 

 but rather ill-defined white area, which spreads slightly 

 between the hind legs and markedly between the fore legs 

 on the chest, where it is set off both on the throat anteriorly 

 and on the inner side of the limbs by bright nearly orange- 

 yellow hairs. The anterior part of the throat behind the 

 interramal area whitish, but the sides of the neck and the 

 cheek covered with hairs banded with black and blight 

 yellow. The top of the head, and especially the muzzle,
