Nomada dissessa sp. nov. 
Female. — Length, about 6 millimeters; ferruginous red, the 
head and thorax dusky, but the clypeus, supraclypeal area, 
tubercles and scutellum paler; no yellow anywhere about the 
insect ; face broad ; mandibles and labrum simple ; antennae 
long, scape red, flagellum black with a very obscure reddish 
tint beneath; third antennal joint long, fourth shorter; meso- 
thorax bare, coarsely punctured, shining beneath the punctures ; 
scutellum bigibbous; pleura and metathorax with conspicuous 
white hair; tegulae bright ferruginous; wings hyaline, faintly 
dusky, more so at apex ; nervures and stigma dark rufo-f uscous ; 
only two submarginal cells, basal nervure going basad of trans- 
verse median; second recurrent nervure joining second (mor- 
phologically second + third) submarginal cell a considerable 
distance from its end; legs red, hind tarsi darker; abdomen 
shining red, hind margins of first four segments broadly and 
conspicuously dusky; first segment with two large triangular 
dark areas ; segments 2 to 4 each with lateral patches of glittering 
white hair, only seen in a side view of the abdomen. 
Luzon, Mount Maquiling {Baker). In my table of Philip- 
pine Nomada this runs straight to N. palavanica, a smaller 
species without dusky bands on abdomen. It really most re- 
sembles N. lusca Smith, but is not a variation of that with 
only two submarginal cells, as the mesothorax is more coarsely 
sculptured, the area of metathorax is more polished posteriorly, 
and the first recurrent nervure joins the second submarginal 
cell very much nearer its base. 
Nomada polyodonta sp. nov. 
Male. — Length, about 6.3 millimeters ; head and thorax black, 
with the following parts ferruginous : Lower margin of clypeus 
broadly, lower corners of face, labrum, mandibles, upper border 
of prothorax, tubercles, anterior corners of mesothorax, greater 
part of pleura (but not bright, and lower part black), scutel- 
lum, and postscutellum ; front and mesothorax very densely and 
coarsely punctured; head large, with broad face, which is cov- 
ered with glittering white hair; scape black, with a bright red 
spot at base in front, more or less extended as a line upward; 
flagellum black, chestnut red beneath, the joints conspicuously 
denticulate; second antennal joint concealed, third about equal 
with fourth; thorax bare above, pleura and metathorax with 
rather thin white hair; tegulse bright fulvo-ferruginous ; wings 
strongly dusky at apex; stigma and nervures piceous; basal
