yellow slits, each located on a well-defined ridge. Button large, 

 round, red. Spiracles located a short distance above the longitudinal 

 axis. Anal opening small, far below the spiracles. 

 Length, 7 mm. ; diameter, 2.75 mm. 



91. PHOROCERA, gpcciea (near MACRA). 



Medium-sized ; subshining. Stigmal plates shining black, slightly 

 raised above surface. Plates separated by a space equal to one-half 

 of one plate. Each plate has three red slits, each on top of a ridge. 

 Button round, fairly distinct. Spiracles located on longitudinal 

 axis. Between and partly below the stigmal plates is a large, rugose 

 tubercle. Anal opening small, far below the spiracles. 



Lenth, 7 mm. ; diameter, 2.75 mm. 



92. PANZERIA AMPELUS Walker (Varichaeta ampelns Walker). 



Medium-sized; dull, dark red, very minutely rugose. Spiracles 

 shining black, slightly raised above the surface, separated by a space 

 equal to one-third of one stigmal plate. Each plate has three red- 

 dish slits. Button medium-sized, round. Spiracles located on longi- 

 tudinal axis. Just below the spiracles is a transverse, diamond- 

 shaped elevation with a median depression. 



Length, 7.5 mm. ; diameter, 2.5 mm. 



93. EXORISTA FUTILIS Osten Sacken (Euexorista futilis Osten Sacken). 



Medium-sized; dull, dark red. Spiracles shining black, slightly 

 raised above the surface, divided by a space nearly equal to one-half 

 of one stigmal plate ; area between plates smooth and shining. Each 

 stigmal plate has three slits, each of which are located on a well- 

 defined ridge. Button round, well defined. Spiracles located on the 

 longitudinal axis. Anal opening small, far below spiracles. 



Length, 8 mm. ; diameter, 3.75 mm. 



94. PHOROCERA CLARIPENNIS MacQuart (Euphorocera tachinomoides Townsend). 



Large ; dull, dark red. Spiracles black, subshining, slightly raised 

 above the surface, widely separated, the space between equal to about 

 one-half the width of one plate. Each plate has three dark-red slits, 

 each located on top of a well-defined groove. Button round, reddish, 

 rather well defined. Spiracles located above the longitudinal axis, a 

 distance about equal to the length of one plate. At the base and be- 

 tween the spiracular plates is a rugose, rounded, blackish elevation 

 with a central depression. Anal opening small, far below the 

 spiracles. 



Length, 8 mm. ; diameter, 3.5 mm.
