THE PROSOPID^, OR OBTUSE-TONGUED BEES, OF THE 
PHILIPPINE ISLANDS 
By T. D. A. COCKEEELL 
{University of Colorado) 
The Prosopid£8, represented by the genus Prosopis Fabricius, 
are easily recognized among the Philippine bees by their small 
size, short emarginate tongue, and scanty development of hair 
on the body. The wings have a large stigma and only two 
submarginal cells. The only Philippine bees that can be 
confused with them are the species of Allodape, which are 
long-tongued. In Allodape the face marks are unlike those of 
Prosopis, the broad light mark down the middle of the face 
being especially characteristic. The Prosopis philippinensis of 
Ashmead is an Allodape. 
The Philippine species of Prosopis, so far as known, may be 
separated thus: 
Abdomen steel blue worcesteri sp. nov. 
Abdomen black 1. 
1. Clypeus entirely yellow in male; small slender species, with the tarsi and 
greater part of the tibias yellow; lateral face marks not going above 
level of antenns taclobana Cockerell. 
Clypeus entirely black in female; lateral face marks cuneiform, truncate 
above; tubercles broadly edged with white; stigma piceous; abdomen 
strongly shining; both recurrent nervures meeting transverse-cubitals. 
tagala Ashmead. 
Clypeus black with a light patch or spot 2. 
2. Lateral face marks cuneiform, not extending along orbital margins above 
level of antenna 3. 
Lateral face marks extending above level of antennae 4. 
3. Mesothorax coarsely punctured, shining between the punctures. 
cuneifera sp. nov. 
Mesothorax entirely dull and very finely and densely punctured; scutel- 
lum with large punctures opaeissima sp. nov. 
4. Scape with a light mark in front; light area on clypeus triangular, 
pointed above 5 . 
Scape entirely black; light area on clypeus not pointed above 6. 
6. Hind tibiae entirely black in male palavanica Cockerell. 
Hind tibiae broadly yellow at base in male mindaneiisis Cockerell. 
6. Clypeal mark shaped like a tall hat; upward extension of lateral face 
marks cuneiform, not extending far above antennae. 
benguetensis sp. nov. 
Clypeal mark a spot near lower margin; upward extension of lateral 
face marks narrow 7.
