])laU>s hardly tlioir (liametcr apart, each with throe straight shts, 

 rather thvergeiit from those of the opposite phite. 

 Yvom Sarracenia Jfava from Florida. 



Sarcophagid B. 

 (Plate IV, figs. 72, 76, 79, 80.) 



Body moderately stout. Head small, seen from above truncate 

 and slightly emarginate in middle; two approximate mandibles. 

 Anterior spiracles of about 12 lobes; anterior margin of segment 3 and 

 folloA\ing with a spinulose, elevated ring, widest on the ventral part ; 

 also on the posterior margin of segment 4, and following segments, on 

 each side of venter, a short fusiform, elevated, spinulose area pressing 

 against the basal ring of the next segment ; much of the general surface 

 of segments also minutely spinulate, but on the venter are some 

 transverse, shghtly elevated smooth spots; on segments 3 and 4 are 

 two each side, on segment 5 and following is'a transverse elongate 

 area, each side of which bears three more elevated spots, two at the 

 median end, approximate, the other at the lateral end; outside of 

 tliis is still another, less distinct, smooth, elevated spot; on the median 

 line before these is another elevated area, transversely striate. On 

 the pleuron of each segment, about where one might expect spiracles, 

 there is a smooth, rounded, elevated spot, faintly double on some of 

 the })osterior segments. On the dorsum of segments 3, 4, 5, and 6 

 there is a transverse, anterior row of small, smooth tubercles. From 

 the fifth the follo^\^ng segments, from above, appear divided trans- 

 versely into three subec^ual rings, all spinulose. At tip the anal area 

 is prominent, spinulose, and bears at each outer corner an outwardly 

 directed spinulose cone. The stigmal pit is elhptical, one and two- 

 tliirds times as long as broad, its upper lip with three subequal, 

 spinulose cones each side; its lower Hp with two similar cones each 

 side, and a mecUan pair smaller, and situated more towao-d the anal 

 area. The stigmal plates, as usual, have three elongate, simple shts; 

 those of one plate subparallel to those of the other. 



These larv?e were taken from Limburger cheese on two occasions, 

 and an extremely similar form was received as having been passed in 

 feces. 



Sarcopliaga sarracenisel (so labelled). 



Body pitted over almost the entire surface, and from each pit 

 arises a tiny stiff bristle; sometimes the sin-face is minutely wrin- 

 kled, and near the tip more spinulose. The anterior spiracles show 

 about 12 lobes. The posterior ventral half of segments 3 and 4 is 

 smooth, but the posterior ventral area of the others is crossed by a 

 ])road band of these pits and bristles. Around each segment is the 

 usual basal ring, and on the posterior sides is the usual fusiform area
