that of terrestris. The indications are that Smith mixed two species 
under tunicatus, which explains the discrepancy referred to above. 
Bombus niveatus callophenax subsp. nov. 
Female: Length about 19 mm.; exactly like B. terrestris sim- 
laénsis in color and appearance, except that it is considerably less 
robust, but easily separated by the third antennal joint, which is 
about three times as long as fourth, longer than fourth and fifth, 
but not quite equal to 4-6; also by the much longer malar space, 
which is fully 1.5 times its apical width. From typical B. niveatus 
(which I have from A. Skorikov) it is known by the white and black 
hair on the second abdominal segment being arranged as in sim- 
laénsis, the lower edge of the white strongly curved, not reaching 
hind margin of segment. The surface of the clypeus is more pol- 
ished and less punctured than in niveatus. It differs from B. 
gilgitensis at once in the malar space, the distinctly though deli- 
cately punctate apical segment of abdomen, the white hair of 
scutellum not mixed with black, and venter of abdomen without 
fulvoferruginous hair. The apical abdominal segment has scanty 
black hair (it is red in niveatus), and the wings are dark reddish, 
much darker than in niveatus. From B. incertus it is easily known 
by the antennz. Kashmir (R. L. Woglum). U.S. Nat. Museum. 
Perhaps a distinct species, to be called Bombus callophenaz. 
Trigona mirandula sp. nov. 
Worker: Length about 5 mm., rather robust, shining; head large, 
broader than thorax, but facial quadrangle considerably longer 
than broad; mandibles without teeth, basal half yellow, apical 
red; labrum yellowish; cheeks pale yellow suffused with red; malar 
space obsolete; clypeus ferruginous, the lower margin pale yellow; 
supraclypeal area and lower half of middle of front pale reddish, but 
sides of face almost to summit of eyes with extremely broad pale 
yellow bands; upper half of front black, with a median yellow line; 
vertex black; scape light ferruginous, darkened at apex; flagellum 
dark above, reddish beneath; mesothorax black, with narrow 
lateral margins, which extend to axillae; rest of thorax clear red; 
legs red, hind tibize longitudinally divided red and black, the black 
extending right across apically; hind basitarsi largely dark; hind 
tibiz broad, but not extremely so, the fringing hairs pale red;
