[ Cremastus 



Shoreham in Sussex. It is certainly rare with us and has probably been 

 mixed witli the next species, from which the trans-strigose metathorax 

 distinguishes it, though I am not satisfied that the comparative length of 

 the discoidal and brachial cells is constant, for my Felixstowe male has 

 them by no means equal, while in Bankes' male the basal nervure is 

 exactly continuous, witli the notauli equally obsolete and stigma dark in 

 both. 1 possess a single Sufiblk pair, found on flowers of xingchca syl- 

 Vis/ris at Claydon Bridge during the afternoon of 12th August, 1899, and 



on those of another umbellifer [Silaiis flavesccns) on the coast cliffs at 

 Felixstowe on 20th of the following August. Bankes has given me a 

 male, along with the two female Pimpla riificollis — cf. Brit. Ichn. iii. 59 — 

 from Retiiiia bnohmia''' on 23rd July, 1903, at Corfe Castle in Dorset. 

 Monk Soham in August, 1909.

 no pertinent points of difference and they have now been bred from the same host. The description 

 is thus : — A black species ; head with the orbits more narrowly in ? , clypeus and mandibles except 

 their apices flavous, and palpi piceous ; antennae subelongate, with apices of the basal joints pale 

 beneath ; thorax black with humeral lines flavous ; scutellum flavous, of tf sometimes with a spot
