Of this singular genus only one species appears to have 

 been described, and that has never been recorded as British : 

 we have had the good fortune to discover eight others of which 

 we shall give short descriptions, first observing that all, ex- 

 cepting No. 6, are black and shining, with ochraceous legs. 



I. Stigma short, subtrigonate. 



A Oviduct shorter than the body. 



1 A. Manducator, Panz. Faun. Germ. fas. 72, 7i. ^^fem. — 



Antennee very pubescent in the female, rather robust, 

 ferruginous at the base. 



2 apicalis iVo6. — Mandibles black at their apex. 



3 similis iVoi. — Smaller, antennae black at their base, 



mandibles entirely ferruginous. 



B Oviduct as long as the body. 



4 Pratellae 'Noh. — Black, shining, legs trophi and base of 



antennae ferruginous. Head very large. Antennae 

 very long, slightly pubescent. Stigma narrow. 



5 graciUs ^ob. — Oviduct not longer than the body. 



Head small, ferruginous next the eyes. Antennae 

 entirely piceous. 



6 pallida 'Nob. — Dull ochraceous, eyes and a spot be- 



tween them black ; metathorax and base of abdo- 

 men black; apex piceous; antennae and nervures 

 of wings fuscous. 



II. Stigma elongated. 



7 Apii 2Vb&. 



8 pubescens iVoJ. — Oviduct short, but visible. Smaller 



than the last, covered with pale pubescence, espe- 

 cially the thorax. 



9 minuta No6. — Small, nervures of the wings very strong 



and black. 



A. Manducator is not uncommon upon umbellate plants in 

 meadows, the dung of animals, &c. 



A. PratellcE. Found with some Cynipsidcc the end of Sep- 

 tember in the park of Heron Court, Hampshire, by my 

 esteemed friend the Hon. Charles A. Harris, who disco- 

 vered them concealed between the collar and gills of very 

 young mushrooms. 



A. Apii. For specimens of this insect and their history I am 

 indebted to a lady who found the larvae feeding upon 

 the parenchyma of celery leaves the 30th Sept. ; on the 

 11th Oct. they had changed to shining oval pupae of a 

 dull ochre colour, having very much the appearance of a 

 shell [Turbo Chrysalis oi Turton); the imago appeared 

 the June following. 

 Our insect receives its specific name from the genus of 



plants to which it is destructive; and Apium graveolens (Wild 



Celery) being an indigenous species, it is figured in the plate.
