Medium-sized; dull, black puparium. Some specimens have a 

 faint reddish tinge. Spiracles somewhat triangular in form, lo- 

 cated on very prominent protuberances, which touch at the base 

 and are separated by nearly their own width at the apex. Each 

 spiracular plate has three lobes, and each lobe has very irregular, 

 dark-yellow slits located on a shiny, black surface. Button well 

 defined, located centrally on longitudinal axis. Anal opening small, 

 located some distance below the spiracles. 



Length, 7.5 mm. ; diameter, 3 mm. 



14. COQUILLETTINA PLANKII Walton (Hemithrixion plankii Walton). 



Medium-sized; dull, blackish-red puparium. Spiracles shining 

 black, located on well-defined protuberances, which touch at base 

 and are separated at apex by nearly their own width. Slits are 

 angular and located on top of well-defined ridges. Button well 

 marked. Protuberances located above but touching longitudinal 

 axis. Anal opening very small, located near middle of lower half 

 of end view. 



Length, 6.5 mm.; diameter, 2.75 mm. 



16. BELVOSIA BIFASCIATA Fabricinf (Latreillemyia blfasciaU Fabricias). 



Very large; dull black puparium. Caudal end larger than an-

 the surface of the puparium, with three very long serpentine slits, 

 which are slightly yellowish. Button round, distinct. Segmental 

 lines plainly seen on the dorsum. Anal opening small, indistinct, 

 crescent-shaped, located just above longitudinal axis.

 ant, black, shining at apex, dull and finely granular at base, located 

 on longitudinal axis, mostly below the line, each with two serpen- 

 tine slits situated on top of a prominent protuberance, these pro- 

 tuberances narrowly separated at base; inside flat surfaces nearly 

 parallel. Anal opening less than width of the protuberance from
