Tachinophyto floridensis Townsend. A common species, which 

 has been collected from. May to November. Taken from flowers and 

 by sweeping grass. The species is small and varies in size from 4 to 

 7 mm. in length. It resembles Cclaforia diabroticac very closely. A 

 few characters which may serve to distinguish it are given here. 



Eyes nearly bare, microscopically, sparsely hairy ; face receding 

 below, antennae usually not reaching the oral margin, arista thickened 

 on basal 2-5 ; scutellum with three marginal and a shorter discal pair 

 of macrochaetae, with an additional suberect apical pair, sometimes 

 very small. Apical cell narrowly open and ending shortly before ex- 

 treme wing tip. Third vein with at least two bristles near the base. 



Tachinophyto dunningii Coquillett. An abundant, minute species, 

 readily recognized by the shiny black abdomen with the narrow bases 

 of last three -segments white pollinose. Collected from flowers, but 

 more frequently from low foliage. Common from May to October. 

 Series of specimens about uniform in size, measuring 5 mm. 



Tachinophyto vanderwulpi Townsend. A small species like the 

 above. Much less abundant. Frequently taken in company with 

 Tachinophyto floridensis, which species it resembles closely, although 

 usually smaller. Collected largely from foliage near the ground. 

 Specimens range from 4 to 5.5 mm. in length. 



Trichophora ruficauda v. d. Wulp. Collected from April to 

 November from foliage and flowers. Persistently common, but not 

 abundant. Usually elongate, but some specimens are robust and re- 

 semble Peleteria rohusta very closely. Specimens range from 8 to 11 

 mm. in length. Listed from Texas, by Coquillett, Revis. Tachin. N. A. 

 1897, p. 139- 



Winthemia quadripustulata Fabricus. Very abundant and wide- 

 spread. Common throughout the year. Collected from many different 

 flowers, but it can be more frequently taken from low foliage and 

 grass. In flight it has a distinct high-pitched note. A long series of 

 specimens show a great variation in color markings. The most com- 

 mon form has the sides of the abdomen yellow, but frequently yellow 

 only, on the second and third segments. In several specimens the 

 abdomen is wholly black except the last segment, which is yellow. A 

 few others have the abdomen bright orange-yellow excepting a medium 

 dorsal row of black spots. Also a great variation in size, specimens 

 ranging from 5 to 12 mm. in length. Reported by Parks as very 

 abundant in wheat fields infested by the army worm of northwest 

 Texas. A parasite of Lepidoptera and reported as having been bred 

 from a large number of species.
