taken it at Shere, in Surrey ; and Chilly at Hunlingfit-ld, in Kent, in 

 August. 



3. brevicornis, Tasch. 



Phygadeuon oviventris, Gr. I. E. ii. 648, excl. 6 . P. brevicornis, Tasch. Zeits. Ges. 

 Nat. 1S65, p. 48, 9 . 



Head stout and black ; the discreled clypeus, face and vertex very 

 finely and closely punctate with isolated larger punctures ; mouth flavous. 

 Antennae filiform, red-brown, stout, apically obtuse and rather shorter than 

 half the body ; basal half of flagellum with short, moniliform joints of equal 

 breadth ; scape ferrugineous below. Thorax immaculate ; metathorax dull 

 and finely alutaceous ; only the nitidulous apical transverse costa and short 

 lateral ones, beyond the circular spiracles, present. Scutellum black. 

 Abdomen oblong-ovate, as broad as the thorax, and basally closely punc- 

 tate ; black, with segments five to seven white-margined ; basal segment 

 dorsally deplanate, laterally straight and gradually explanate apically ; 

 terebra slightly reflexed and half the length of the abdomen. Legs stout, 

 entirely red ; tibiae sericeous. Wings somewhat ample and hardly clouded ; 

 radix white, tegulae fulvous. Length, 7 mm. 



Brischke has placed this female, of which Thomson makes no mention, 

 in the present genus, where it is closely allied to C. nigriventris in its stout 

 head and antennae, short flagellum, circular spiracles, the conformation of 

 the basal segment, and the stout legs. Schmiedeknecht, in 1905, queries 

 the synonymy of P. brevicornis therewith, while admitting Gravenhorst's 

 male, P. oviventris, to have been originally correctly associated with its 

 female. From C. nigriventris, however, the present species may be known 

 by its broader abdomen, which has the apical segments white-margined, 

 and the metathoracic costae are more obsolete. 



This species was first noticed in Britain by Marshall in 1872 ; but I 

 have heard of no records. On the Continent it is found, in early September, 

 on the flowers of Ang;elica sylvestris. There is a male, which may belong 

 to this species, from Shere, in Capron's collection.
