162 FIGITES ANTHOMYIARUM. 



haired ; the pleurae striolated, not so strongly at the edges. Scutellum 

 punctured, less strongly at the base ; the basal fovese large, roundish, 

 shining, the apex of scutellum subtruncate. Parapsidal sutures dis- 

 tinct ; two short lines at the base of mesonotum. Median segment at 

 the stigma projecting as a short tubercle, the central keels distinct but 

 somewhat irregular ; the whole of the median segment is rough. Petiole 

 stoutly longitudinally striolated; the base of the second segment 

 striated. Wings clear hyaline, the nervures testaceous, the apex 

 ciliated. 



The <$ differs in having the antennae longer than the body, the 

 flagellum almost entirely reddish-yellow, the third joint slightly in- 

 cised, the scutellum is not so strongly punctured, the face shining, 

 smooth, the base of the second abdominal segment is not striolated, 

 and the femora are largely lined with black. 



Length 2'5 3*5 m.m. 



The colour of the antennas in the ? varies, some 

 'specimens having the flagellum almost entirely black, 

 while others have it for the greater part reddish ; in 

 the 3 it is usually entirely reddish-yellow, but some- 

 times it is largely infuscated towards the apex. In 

 the ? the hind femora maybe more or less infuscated. 

 The striolation on the thorax varies in intensity. 



In the coloration of the legs it agrees best with 

 P. urticarum, but the keel on the mesosternum offers 

 a ready means of separation. 



The larva, according to Bouche (1. c.), is one line 

 long ; longish, narrowed posteriorly, contracted in the 

 middle, white, soft, uneven, and very finely wrinkled. 

 Head roundish ; the mandibles yellow, brown and 

 bidentate at the apex. The mesothorax is strongly 

 enlarged, larger than the other rings. The metathorax 

 and the first abdominal segment are strongly narrowed, 

 forming a sort of waist. Abdominal segments have a 

 convex back; the anal segment small, rounded. Stigmas 

 pale yellow. 



The larvse were found by Bouche in the harvest and 

 winter in the pupas of species of Anthomyia, dentipes, 

 floralis, &c. 



Not uncommon. Clydesdale; Cheshire. August 

 and September. 



Continental distribution : Sweden, Germany, Aus- 

 tria, France.
