ABT. 5 GENERIC REVISION OF THE FOSSORIAL WASPS PARKER 141 



The paratype differs from the type in the absence of any black on 

 the clypeus; in the presence of a yellow spot on the side of the 

 prothorax and another on the metapleura; and in the fact that the 

 lateral spots on the scutellum form a curved fascia interrupted 

 medially. In Handlirsch's table this species runs to infiiinata., but it 

 differs from that species in the greater infumation of the wings and 

 in having all the fasciae on the tergites, except that on the first, 

 continuous. 



Length 17 mm. Described from two females from San Luis 

 Potosi, Mexico. 



Type. — In the collection of Massachusetts Agricultural College. 

 Amherst, Mass. 



BEMBIX LUZONENSIS, new species 



Type (female). — Black: labrum; mandibles, except tips; clypeus. 

 except broad, black basal border ; line on scape below ; lower border of 

 frons limited between the antennae by a black spot extending from 

 the insertion of one to the insertion of the other and prolonged up- 

 ward by a very narrow median line dividing the yellow above the 

 antennae along the midline; spot below anterior ocellus connected 

 with yellow of frons below; short anterior orbits; posterior orbits 

 very narrow above; narrow posterior border of pronotum; side of 

 prothorax, except spot on tubercle; small spot on lateral angle of 

 propodeum ; broad, vertical anterior spot on side of propodeum ; two 

 elongated spots on metapleura; oval posterior spot and large, irregu- 

 lar anterior spot on mesopleura; widely separated lateral spots on 

 first tergite ; continuous fascia on second tergite with wide posterior 

 dorsal emargination that is extended into the fascia on right and 

 left; continuous fascia on third tergite with pair of deep, rounded, 

 anterior, dorsal emarginations and broad, shallow, median posterior 

 emargination; continuous fascia on tergite 4 similar to that on 3; 

 fascia on tergite 5 interrupted at dorsal midline; small lateral spots 

 on sternites 2-3 ; anterior coxae below ; line on anterior and posterior 

 borders of all femora; all tibiae above; and anterior tarsi above; 

 pale creamy yellow. 



The flagellum is black. The inner eye-margins are very slightly 

 divergent at the clypeus. The pubescence is very short and incon- 

 spicuous. The wings are lightly and uniformly infumated and the 

 second abscissa of both radiella and cubitella is present. The an- 

 terior metatarsus is provided with only five spines. The disk of the 

 second sternite is smooth and shining and bears scattered, coarse 

 punctures. The sixth sternite is feebly carinate on midline and is 

 densely covered with very fine punctures, among which are scattered 

 many coarse ones and consequently is covered with a fine pubescence.
