Description 
Female 
Length about 6.0 mm; wing length about 5.0 mm. 
Relative head measurements: width 7.2; length 9.0; 
length labial palp approximately 10.0; lower 
interocular distance 4.6; upper interocular distance 
4.9; interantennal distance 1.4; antennocular 
distance 1.0; interocellar distance 1.8; ocellocular 
distance 1.3; ocelloccipital distance 0.7. Fronto- 
clypeal suture indistinct, labial palp segments of 
increasing lengths in the order 1, 2, 4, 3, with 1 and 
2 dark brown, 3 and 4 ribbon-like, whitish, 
segment 3 expanded basally (Figure 15), malar 
space evident; dorsum of head covered with fine 
reticulation, shining; supraclypeal area and clypeus 
medianly concave and brilliantly shining. Legs 
dark brown with distal end of femora, fore tibiae 
and all tarsi pale yellowish. 
Male 
Similar to female with more extensive long white 
hair on body. In specimens from Leonora, the gastral 
tergum 6 is wholly yellow (partially so in others). 
Remarks 
My theory that species of Eremophila are attended 
by bee species with mouthparts suitably modified 
is shaken by this species. It was taken at the same 
time as the species E. leonora which shows no 
marked lengthening of head or labial palps. 
Etymology 
The specific name refers to the species of 
Eremophila from which the bees were collected. 
Euryglossa (Euhestna) sulcata sp. nov.

Description 
Female 
Length about 6.5 mm; wing length about 4.5 
mm. Relative head measurements: width 8.0; 
length 9.5; clypeal length 2.3; lower interocular 
distance 5.2; upper interocular distance 5.4; 
clypeo-antennal distance 0.4; interantennal 
distance 1.9; antennocular distance 1.0; 
interocellar distance 1.8; ocellocular distance 1.5; 
ocelloccipital distance 1.0. Anterior margin of 
clypeus indented medianly, upper margin of 
clypeus indistinct, almost straight; clypeus with 
median longitudinal furrow; labial palps (Figures 
6, 17) as long as head, segments of increasing 
length in the order 1 = 2, 3, 4, segments 1 and 2 
dark brown, segments 3 and 4 expanded, ribbon¬ 
like, golden; horizontal zone of propodeum 
longer than metanotum; frons above antennae 
covered with close reticulation and sparse 
punctures, interspaces shining; clypeus and 
supraclypeal area shining. Legs dark brown with 
tarsi golden. 
Male 
Length about 5.5 mm; wing length about 4.2 
mm. Relative head measurements: width 8.9; 
length 9.0; clypeal length 2.4; lower interocular 
distance 5.7; upper interocular distance 6.0; 
clypeo-antennal distance 0.4; interantennal 
distance 1.7; antennocular distance 1.4; 
interocellar distance 2.0; ocellocular distance 
1.6; ocelloccipital distance 1.1. Anterior margin 
of clypeus slightly indented medianly, upper 
margin of clypeus indistinct, slightly concave; 
clypeus with median longitudinal furrow; labial 
palps as in female; facial foveae broad, shallow 
depressions, indistinct; basitibial plate 
margined by incomplete carinae and tubercles, 
about 1/3 length of hind tibia; inner hind tibial 
spur finely pectinate; horizontal zone of 
propodeum longer than metanotum; frons 
above antennae covered with close reticulation, 
punctures more numerous and closer together 
than in female; foveae of second tergum of 
gaster indistinct. Colour as in female with fore 
tibiae golden. Terminalia as in Figures 26, 27, 
35, 44. 
Etymology 
The specific name is from Latin and refers to the 
furrow medianly on the clypeus.
