SCHILDOMYIA PUNCTIFRONS, new species 



Male. — Head much as in vittithorax^ but the frons is rufous in front 

 centrally, the face is fuscous, with dense gray dusting in middle, not 

 with a black central mark, the cheeks are largely dark brown, and 

 the antennae have the second segment and a spot on outer and an- 

 other on inner side of third segment blackish. Thoracic dorsal 

 markings as in figure 16 ; pleura with the following chocolate colored 

 markings: a line along upper margin, a vitta on middle of meso- 

 pleura and pteropleura, interrupted on micldle of former, another 

 along upper margin of sternopleura, and the lower half of sterno- 

 pleura. Abdomen black, hind margins of tergites narrowly yellow, 

 becoming broader laterally. Coxae and femora almost entirely, 

 and two annuli on each tibia, fuscous. Cross veins of wings rather 

 noticeably clouded. 



Structurally similar to hrevihirta., but the cross veins are more 

 widely separated, the fourth vein is less distinctly curved forward 

 apically, and the size smaller. 



Length, 3.5 mm. 



Type. — Higuito, San Hateo, Costa Kica (P. Schild), Cat. No. 

 28462, U.S.N.M. 



I am a little doubtful of the sex of this specimen and, as it is 

 rather badly covered with filamentous growth, do not desire to 

 tamper with it to determine whether it is a male or not, though 

 I suspect that it is of that sex.

 spot, interfrontalia on each side of triangle, upper part of occiput,

 sides of labrum dark brown; antennae and palpi yellow. Thoracic 

 dorsum chocolate brown, with lateral margins and four vittae in 

 front of suture yellowish gray pruinescent, only the submedian pair 

 extending beyond suture, behind suture there are five similar vittae, 

 the median one least conspicuous; pleura concolorous with inesono- 

 tum, with a pale vitta over pro thoracic spiracle and another from 

 above fore coxa to below haltere; scutellum dark brown, with a
