The very prominent horn in front of the head, as well as 

 the remarkably long rostrum which this insect inserts into 

 flowers whilst on the wing, are sufficient characters to mark 

 the genus Rhingia, of which there are but two European 

 species known, and both of them are inhabitants of this 

 country. 



1. R. campestris Meig. 3. 259. 



Common in May, June, and July, flying round and settling 

 upon flowers in gardens, or sunny banks, &c. 



2. R. rostrata Linn. — Fab., Panz. 87. 22. 



Less common than the other species ; it is attached to the 

 same situations ; and has been observed from June to Septem- 

 ber in the neighbourhood of London and in the counties of 

 Devon and Westmoreland. 



The species figured {R. campestris) has been universally 

 considered in this country as the Conops rostrata of Linnaeus ; 

 but upon consulting his description we perfectly coincide with 

 Meigen, to whom we are indebted for this correction, that 

 the insect figured by Panzer answers best to the definition in 

 the Systema NaturcB. 



Lychnis dioica, var. diurna (Red Campion), figured in the 

 plate, is a plant to the flowers of which our genus is particu- 

 larly attached.
