THREE NEW ANTHOPHORID BEES FROM TEXAS. 147 
rent nervure is received beyond the middle of the cellule, and 
the area on the base of metanotum is almost of equal width 
throughout. 
Mutilla devia, sp. nov. 
Black; the head, thorax (the pronotum and the mesopleure 
densely), the apices of the abdominal segments and the legs covered 
with longish white pubescence; the wings hyaline, the nervures 
black; the first abscissa of the radius straight, sharply oblique, about 
one-fourth shorter than the following two united, the second about 
one-fourth longer than the third; the first recurrent nervure is 
received in the middle of the cellule. Tegule dark testaceous at the 
base, the apex white; they are covered with white pubescence. Keel 
on basal ventral abdominal segment distinctly dilated at the apex. 3. 
Length, 7 mm. 
Kuching, Borneo (John Hewitt, B.A.). 
Vertex on either side of the ocellar region finely, closely, longi- 
tudinally striated, sparsely covered with longish black hair; the front 
densely covered with silvery pubescence. Pronotum closely, the 
mesonotum less closely, but more strongly punctured; there are two 
distinct furrows near the centre of the apical half of the mesonotum. 
Scutellum more closely, rugosely punctured than the mesonotum. 
The space bordering the scutellums and the base of the metanotum 
densely covered with depressed silvery pubescence. There is no 
clearly defined area on the base of the metanotum unless it is hidden 
by the dense pubescence; the metanotum is rather coarsely reticu- 
lated. Calcaria white. Third antennal joint about dne-quarter 
longer than the fourth.

Tetralonia argyrophila, sp. nov. 
3. Length about 134 mm., black, with the hair on the head, 
thorax, and basal segment of abdomen (covering the latter densely) 
ochreous, rather bright on the thorax above. Clypeus bright lemon- 
yellow, the yellow angularly incised laterally ; labrum cream-colour 
with a narrow black edge; mandibles without any yellow spot; 
antenns very long, entirely black; third joint very short, its shorter 
(anterior side) about as long as its apical breadth antero-posteriorly ; 
mesothorax dull, densely punctured; area of metathorax rugose; legs 
with pale hair, that on inner side of basitarsi light orange; middle 
tarsi not distorted; hind spur of hind tibiz normal; abdomen beyond 
the first segment shining black with sparse black hair, but with scat- 
tered long silvery-white hairs, becoming numerous toward the apex, 
and forming a sort of thin fringe on the sides of segments four to six ; 
apical margin of sixth and sides of seventh with short light hair. In 
my table in Trans. Amer. Ent. Soc. 1906, this runs to 4 on p. 79, and 
does not precisely fall in either category there indicated. On the whole
