Oeratitis capitata Wied. 



(Plate V, figs. 87, 88, 89, 100.) 



Bod}' moderately tapering in front, not particularly slender; 

 two distant mandibles; liead from above bilobed; anterior s])iracles 

 long, with about 15 lobes. The segments show on the venter the 

 usual transverse, fusiform, spinulose areas, and between them on 

 the middle of each segment are two low ridges, which in the median 

 area are connected as in the figure, one of them being broken in the 

 middle. On the posterior border of each segment where it joins 

 the next is a row of pits, and also less distinct a longitudinal row, 

 or two of them, on the side of each segment; on some segments 

 these are more like a line or groove. Elsewhere on the segments 

 there are a few longitudinal grooves and ridges. At apex of body the 

 stigmal area is slightly elevated, the plates long, and each has 

 three short, straight slits. Above them on the upper edge is a pair 

 of distant, conical tubercles; below the plates is a transverse, ele- 

 vated crest, and on the lower slope is an elliptical, medial area, 

 spinulose around the edge, and containing the two anal tubercles, 

 elongate, and pear-shaped, but not much elevated. 



This is the peach maggot of tropical countries. 



Acidia fratria Loew. 

 (Plate V, figs. 91-93.) 



Body very pale; not very slender; two approximate mandibles; 

 head from above rounded at tip; anterior spiracles long, with con- 

 cave upper edge, and about 24 lobes. No part of body spinulose; the 

 swollen parts of segments not very prominent, and striate or 

 wrinkled, not spinulose. At the tip there are below two smooth, 

 approximate tubercles on the anal area, which is not prominent. 

 At dorsal tip is a large process, a^^parentl}" bilobed from the side, 

 and also from above, bearing in its middle the flat-topped stigmal 

 eminence; the stigmal plates are fully their diameter npart, each 

 with three sliort slits <lirected toward those of opposite plate, no 

 apparent button, and no other tubercles. 



This species mines th<> leaves of the parsnip. 



Dacus ferrugineus Fab. 



(Plate V, figs. 90, 103, 105.) 



Body rather thick, anterior part not slender; two widely separated 

 mandibles; anterior spiracles long and of about 38 lobes. Anterior 

 margins of segments 3, 4, and 5 minutely transverseh' striated 

 above. The ventral region, beginning witli segment 4, shows the 

 scabrous elevated areas. The last segment shows beneath a large
