of the British Museum, taken it is beheved by Dr. Leach in 

 Devonshire, a female (the one figured) taken by myself in the 

 autumn, I think in the same county ; which is rendered the more 

 probable, because, if it had been a species inhabiting the neigh- 

 bourhood of London, it must have been met with before ; for 

 there can be little doubt that insects so very similar in form have 

 nearly the same habitats. P. ater is by no means a rare insect ; 

 it may be found during the month of July in hedges and trees at 

 Darent, Birch, and Coombe Woods. 



Meigen in 1804 first published this Genus under the name of 

 Fachygaster in his celebrated work in 4to, KlassiJiJmzmb ttnd 

 Besch'eihbng , &c., t. 1. p. 146: in the following year Fabricius^s 

 Systema Antliatorum was published, where the Genus is called 

 Vap2w, which Latreille has adopted ; but as it is clear that Meigen 

 has a claim to priority, I have retained his name in preference, 

 which I am the more inclined to do, because in liis last invaluable 

 work the Genus is again presented to us under the name of 

 Pachygaster. It is a little unfortunate that Germar has applied 

 that name to a Genus of the Curculionidie ; but as that was only 

 pubhshed in 1817, it must of course be discarded. 



The plant figured is Fiola odorata var. alba (Sweet Yiolet).
