This beautiful and extensive genus is distinguished by the 

 structure of the antennae and the nerves of the wings from 

 Corethra and Tanypus^ which it appears to connect. There 

 are ah'eady in our cabinets about 70 species, most of them 

 described by Meigen and Fabricius ; that which has been se- 

 lected for the drawing is a female of a nondescript species 

 taken by Mr. Bentley upon Brockenhurst Heath, Hampshire, 

 the beginning of June 1823 : it is so nearly allied to Meigen's 

 C. elegans {v. \. p. 48. 7i. 63. and tab. 9,.f. 1.), that I at first 

 considered it to be the same ; but it differs not only from his 

 figure, but also materially from the description. Panzer's C. 

 crassipes [fasc. 109. pi. 22.), which I am sorry to see Meigen 

 does not refer to, is probably the male of his C. elegans above 

 mentioned: it is a larger insect than ours, and differently 

 marked. 



Reaumur, in his valuable work {Mem. 1 de VHist. des Ins. 

 torn. 5. pi. 5.), has given copious illustrations of the larvae 

 and pupae of the type of the genus, which were amongst the 

 earliest objects in nature that attracted our notice : the former 

 are the beautiful red worms seen in stagnant water so peculiar 

 in their mode of jerking themselves about; and the latter are 

 the little objects with a globular thorax and feathered head 

 and tail seen lying close to the surface of the water, and de- 

 scending to the bottom when any one approaches. 



The plant is Pinguicula vulgaris (Common Butterwort).
