Sarcophaga. 165 



two postsutural intraalar bristles and only in few cases a præsutural ; 

 two large and one or two small notopleural bristles. Scutellum in 

 male witli two large marginal bristles on each side (sometimes three) 

 and a pair of smaller apical bristles or these latter wanting; in female 

 scutellum truncate at apex and without apical bristles; a pair of 

 discai or præapical bristles present. Three sternopleural bristles, 

 more or less distinctly placed as 1 — 1 — 1; above on pteropleura a 

 bundle of hairs with some bristles. Postalar declivity with more or 

 fewer hairs. Abdomen elongated, cylindrical and more or less conical; 

 excavation on second segment reaching to or near to the hind margin 

 in male, but not in female. Only marginal bristles present, none on 

 second segment, third segment with or without a middle pair, fourth 

 segment with a middle pair and fifth with a row. The sternites with 

 long, erect or with shorter, decumbent hairs, especially the fourth 

 sternite showing characters as regards its hairiness. Fifth sternite 

 in male deeply excised, often quite to base and forming two long, 

 narrow or broader lamellæ of somewhat various shape and hairiness. 

 Upper forceps not cleft to base; arms of lower forceps small, not 

 elongated, forming more or less triangular pieces. Legs with the 

 hind coxæ hairy behind; in male posterior femora, especially middle 

 femora on basal part, generally more or less fringed below with 

 long soft hairs, and often hind tibiæ likewise on antero- and postero- 

 ventral sides or only on posteroventral, and sometimes also middle 

 tibiæ; in species with thus fringed tibiæ it is to be remarked, that 

 this ciliation may vary considerably, especially according to the size 

 of the specimen, as small specimens may have it less developed to 

 quite disappearing; it then first disappears on middle tibiæ; middle 

 femora in male with or without a comb of generally short and dense 

 spinules apically on posteroventral side (besides anteroventral and 

 anterior bristles); hind femora with an anterodorsal and an antero- 

 ventral row of bristles, and between them an anterior row; the antero- 

 ventral row may be variously developed or wanting; middle tibiæ 

 with a ventral bristle in both sexes, except in male of striata Fabr. 

 Claws and pulvilli strongly elongated in male. Wings with first 

 posterior cell open; discai angle rectangular with a fold as veinlet; 

 cubital vein with bristles towards medial cross-vein; subcostal vein 

 either bare or sometimes with more or fewer bristles. A costal spine 

 present or wanting. 



The larvæ of Sarcophaga (and upon the whole of the Sarco- 

 phaginae) are more elongated cylindrical and conically tapering
