5. sodalis, Tasch. 

 Phygadeiion sodalii, Tasch. Zeits. Ges. Nat. 1S65, p. 29, 9 ; Thorns. O. E. x. 945, $ ? , 



Head black, palpi of ? red, mouth of $ white ; vertex angularly 

 emarginate ; genal sulcu.s wanting ; frons densely and very finely punctate 

 and pubescent, somewhat dull ; face of $ coarsely aciculate apically, of 

 $ with white pilosity ; clypeus not distinctly discreted. Antennae of ? 

 slightly incrassate apically and red basally ; of $ with the scape white 

 beneath. Thorax immaculate ; mesonotum densely and very finely punc- 

 tate and pubescent, somewhat dull ; metathorax coarsely rugose, with 

 complete areae ; areola shortly hexagonal, broader apically and emitting 

 the costulae from behind its centre ; petiolar area feebly discreted ; 

 apophyses weak, spiracles circular. Scutellum black. Abdomen black, 

 with segments two to four entirely, and the apex of the first, red ; anus 

 white ; basal segment rather broad, punctate and strongly bicarinate ; 

 second and the base of the third coarsely, deeply and confluently punc- 

 tate ; terebra slightly shorter than the first segment. Legs red, with the 

 hind tarsi and apices of their tibiae black ; $ with the anterior trochanters 

 white ; claws not stout. Wings with the radix white ; radial nervure 

 emitted from the centre of the rather broad stigma ; nervellus antefurcal. 

 Length, 4-6 mm. 



The angular emarginate vertex of the head, together with the peculiar 

 puncturation of the frons, mesonotum and second abdominal segment, will 

 at once distinguish this species. 



Bridgman added this species to the British list (Trans. Ent. Soc. 1886, 

 p. 339) on the strength of a specimen received by him from Mr. J. E. 

 Fletcher, and probably captured at Worcester. A second, from the 

 London district, was exhibited at the S. Lond. Ent. Soc. in March, 1890 ; 

 and I was so fortunate as to sweep a third from herbage, at Brandon, in 

 Suffolk, on 4th June, 1903. On the Continent, where it is somewhat 

 widely distributed, Brischke has bred it, from a species of Syrpfuts, in 

 Prussia. Marshall has taken it at Cornworthy, in Devon.

$ . Head black, with palpi pale ; clypeus discreted, apically truncate, 

 with the basal foveae distinct. Antennae setaceous, half as long again as 

 the body. Thorax immaculate ; metathorax elongate, closely and con- 

 fluently punctate ; areae complete and distinct ; petiolar area oblique, 

 discreted and transversely sub-rugose ; apophyses wanting, spiracles very 

 small and sub-circular. Scutellum black. Abdomen strongly elongate 

 and linear, narrower than thorax ; black, with segments two to four or five 

 entirely, and the apex of the first, red ; anus immaculate ; basal segment
