11. Chaetodaciis mcgregori sp. nov. Plate I, fig. 7. 



Allied to the preceding species, but distinct by the unspotted 

 face, and strikingly characterized by the broad third antennal 

 joint, and by the anal bulla in the wing of the male. 



Panay, Antique Province, Batbatan Island {McGregor). 

 This very peculiar species is named in honor of its collector. 

 Types in my collection. 



Male and female. — Length of body, 5 to 5.5 millimeters; of 

 ovipositor, 0.5; of wing, 4.5 to 5. Head and its bristles exactly 

 as described for the preceding species, but no distinct dark patch 

 on middle of occiput. Antennae a little shorter than face and 

 with third joint broader than in' the allied species; very broad 

 in the male and clothed with very long pubescence, obliquely 

 truncate at the end; entirely yellowish. Face quite unspotted. 

 Back of mesonotum as in the preceding, but paler, the black 

 stripes being less developed; yellow stripe uniting humeri with 

 supra-alar stripe less marked and interrupted in front of suture. 

 Pleura likewise colored, but propleural region more broadly 

 reddish ; mesophragma with a reddish middle stripe. Scutellum, 

 squamulse, and halteres as in the preceding. Bristles black, 

 but scapular, mesopleural, and pteropleural yellowish. 



Abdomen as in the preceding, but first two segments without 

 bjpck sides; black middle longitudinal stripe present only on 

 the last two segments, being quite wanting on third; in the 

 female the fourth segment with a narrow black basal band, 

 which is wanting in the male ; sides of last three segments black 

 spotted in both sexes; oval patches of fifth segment indistinct 

 in both sexes. Third segment of male ciliated; ovipositor very 

 short and entirely of a pale reddish color. Legs as in the 

 preceding, but even paler, the middle tibiae being quite yellowish 

 and the hind tibiae being only darkened, not properly black. 



Wings (Plate I, fig. 7) as in the preceding, but distinctly 

 broader. Costal border equally shaped, but paler and more 

 equal throughout, being not at all dilated at end of first posterior 

 cell; stigma much paler; costal cell quite hyaline; first basal cell 

 only a little inf uscated above second basal one ; anal stripe less 

 indicated in the female, in the male replaced by a shining, 

 sharply separated bulla of a yellowish color, placed just above 

 the prolongation of the anal cell, on its terminal half. Super- 

 numerary lobe of male not much developed.
