9 . Head black, with the palpi red ; clypeus indistinctly discreted ; 

 epistoma protuberant. Antennae brown, distinctly filiform though slightly 

 incrassate towards the apices, basally rufescent ; first joint shorter than the 

 third. Thorax immaculate ; metathorax coarsely rugose with comi)lete 

 areae ; areola hexagonal, broader apically ; petiolar area obsoletely dis- 

 creted ; apophyses small, spiracles circular. Scutellum black. Abdomen 

 black, with segments two to four red, and the anus white ; basal segment 

 slender and elongate, longer than the terebra, with obsolete carinae ; post- 

 petiole and the second segment finely, densely and regularly aciculate, the 

 remainder nitidulous. Legs red ; coxae, trochanters, hind tarsi, apices of 

 their tibiae and of their femora, black. Wings with the radix white, areolet 

 small and the nervellus antefurcal. Length, 4-5 nun. 



This species, Thomson says, resembles F. vagafis in its wings, meta- 

 thorax and clypeal conformation, but the antennae are stouter and brown, 

 and the longitudinally strigose second segment is very distinctive ; the 

 metathorax of the former is coriaceous, and Taschenberg was probably in 

 error in describing it as coarsely rugose, since examples in my collection 

 have the metanotum finely wrinkled and the metapleurae somewhat 

 rugulose. 



S . Head black, with the palpi stramineous ; clypeus indistinctly 

 discreted, basally bifoveate, apically obtusely bidentate. Antennae sub- 

 filiform, a little longer than half the body, and basally ferrugineous 

 beneath. Thorax immaculate ; metathorax coriaceous, basally nearly 

 smooth ; areae complete, with the basal transverse costa straight and 

 continuous ; areola narrow, transverse, entire, apically straight and basally 

 regularly curved ; petiolar area oblique and obsoletely aciculate ; apophyses 

 normal and spiracles circular. Scutellum black. Abdomen narrower than 

 the thorax ; black, with segments three, four and apex or whole of the 

 second, red ; anus immaculate ; basal segment elongate, very gradually 

 explanate apically, and distinctly aciculate, with the spiracles more or 

 less projecting upwards ; second segment distinctly aciculate, remainder 

 smooth and shining. Legs normal, red ; coxae and trochanters black, 

 latter red beneath ; hind tarsi and tibiae infuscate. Wings not clouded ; 

 stigma black, radix and tegulae white. Length, 5 mm. 



It will, I think, be seen from the above descriptions that no doubt 

 can remain that Taschenberg's species must be associated with Graven- 

 horst's ^ . 



(iravenhorst says this species, which is found throughout central and 

 northern Europe, occurs in July ; but all the liritish captures have been 

 effected in ^^ay and early June. It appears to be confined to the west of 

 England, where it is probaijly not uncommon, and I have never seen it in 

 the eastern counties. ]\Ir. I'arfitt found it on the window of his house in 

 Exeter; Uarrett took it at I'embroke ; Davies has sent me both sexes, 

 associating with Crahro Wesmacli, from S. Issey, in (Cornwall ; and Char- 

 bonnier finds it freely at Redland, near Bristol, in May. In Marshall's 

 collection are specimens from Lastingham, in Yorks.
