ZENILLIA PALPALIS, new species 



Figure 2 



Black with ochraceous pollen on the head, thorax, and abdomen. 

 Female. — Head 0.27 to 0.31 of the head width ; the frontal stripe 

 velvet brown, as wide as one parafrontal; parafrontal, parafacial, 

 and posterior orbit with almost golden yellow pollen, that of the face 

 and cheek gray, with a slight tinge of yellow ; front somewhat promi- 

 nent at the insertion of the antennae, forming a slightly oblique 

 angle with the face, the frontal profile and the facial of about the 

 same length. Parafacial at middle as wide as third antennal joint, 

 facial ridges with only three or four hairs above the vibrissae, which 

 are far apart at the oral margin. Cheek one-fifth the eye height. 

 Antennae black, tip of second joint reddish, third joint long and 

 slender, fully four times the second, rounded at tip, reaching almost 

 to vibrissae. Arista rather long and slender, slightly thickened on 



basal third. Palpi (fig. 2) considerably 

 swollen, with a very distinct and striking 

 pocketlike depression or hole on the outer 

 side just before the tip, which is the same in 

 _ all the specimens. Inner verticals large,

in a Single row diverging below toward 

 orbit, reaching to the base of third joint; the usual two proclinate 

 orbitals; parafrontal with only inconspicuous hairs besides the 

 bristles. Mesonotum covered with yellowish pollen, which forms 

 principally three stripes on the sides and middle, leaving a rather 

 heavy black stripe on each side, which is divided anteriorly, 

 the inner and narrower portion extending to the neck, Scutellum 

 with yellow pollen. Thoracic bristles rather stout. Chaetotaxy 

 as follows: Acrostichal, 4, 3; dorsocentral, 3, 4; humeral, 4; noto- 

 pleural, 2; posthumeral, 3; presutural, 2 (the inner large) ; supraalar, 

 3; intraalar, 3; postalar, 3 (the middle one large, the others small) ; 

 sternopleural, 2, 1; pteropleural small. Scutellum with 3 pairs 

 lateral, 1 discal, the apicals slender and upturned, rather long. 

 Propleura bare, prosternum setose, postalar declivity bare, no infra- 

 squamal setules. Scutellum densely covered with coarse erect rather 

 short hairs. Abdomen largely shining black, the yellow pollen 

 forming basal bands on the second and third segments, which are 

 wide at the side and prolonged posteriorly in a blunt point in the 

 middle, leaving considerably more than half the surface shining; 

 fourth segment with yellow pollen except an oval median spot above, 

 which covers the apical two-thirds, but does not extend on the sides.
