TKYPETID-E. 33 



strongly bilobed; the stigmal plates are fully their diameter apart, 

 each with three straight, parallel slits; between the stigmal ])lates and 

 the anal tubercle are two pairs of distinct, rounded, fleshy tubercles; 

 the two nearer the anal tubercle are closer to each other than are the 

 other two. 



Ijocally common in noithern apples. 



Uliagoletis cingulata Loew. 

 (Plate V, figs. 97, 98.) 



Head broad, papilla barely visible, two prominent great hooks; 

 anterior spiracles broad, concave above, with about fourteen lobes. 

 Ventral segments from 5 onward each with a broad, basal, fusiform, 

 swollen area, with many transverse ridges; each ventral segment has 

 also in the middle a transverse hne or furrow; the lateral fusiform 

 areas indistinct; on the dorsal base of segments 3, 4, and 5 is an area 

 of transverse ridges, barely distinct on the following segments; anal 

 tubercle small, slightly roughened, divided by a longitudinal line; 

 stigmal plates not their diameter apart, each with three short, barely 

 curved slits; between the stigmal plates and the anal tubercle, at the 

 extreme tip of the body, are two low elevations or swellings each side, 

 each with a minute central tubercle, the four forming a curved line. 



Common in cherries. 



Epochra canadensis Loew. 

 (Plate V, figs. 81, 82.) 



Body subcylindrical, tapering only a little in front; papilla of head 

 very minute ; two well-separated great hooks ; anterior spiracles broad, 

 broadly emarginate in the middle, with about eighteen to twenty lobes. 

 Ventral segments from the fifth backward with a very narrow, basal, 

 fusiform area, only slightly protuberant, and finely ridged; each of 

 these segments with a ventral, iiiedian, transverse line; no lines or 

 furrows on dorsum; no lateral fusiform areas. Apex of body evenly 

 rounded, smooth, no tubercles; the stigmal plates without a button, 

 each with three short, nearly straight slits; anal tubercle distinct, but 

 small, more yellow than the surrounding surface, slightly convex, and 

 divided by a longitudinal line. 



From currants; more common in the North. 



Anastrepha ludens Loew. 

 (Plato V, figs. 85, 86, 99.) 



Head small, short, bilobed from above; two distinct mandibles; 

 anterior si)iracles long, with twenty or more lobes; on the liflh and 

 the following segments is the usual ventral, basal, fusiform area, with
