A LIST OF THE INSECTS 



OBSERVED IN THE SOUTHERN PART OF THE 



COUNTY OF SUSSEX. 



BY W. C. UNWIN, LEWES. 



In submitting to the readers of "The Naturalist" the following list of 

 some of the Insects of the different orders, observed on the chalk range of 

 the county of Sussex, within a limited district, I would briefly remark it 

 has no pretensions to perfection, as doubtless many species still remain to 

 be added to it; but all that are here noted are from personal observations, 

 or from those of my friends, on whose accuracy I can rely. It is intended 

 the list in its continuation should embrace portions of the other orders, and 

 it is hoped it will be a means of affording some degree of interest to those 

 who delight in the same pursuit. To entomologists of a higher rank it will 

 appear but a trivial effort towards the advancement of science, being, as it 

 is, the result of a collector's notes: but a good collector must necessarily be 

 a tolerably good observer. I will commence with the order Diptera. 



Family Syephid^;* 



* The student in Entomology will find ample details of this interesting family of insects 

 in "Insecta Britannica — Diptera." Vol. I. By Mr. Walker. And also a shorter notice in 

 Dallas's "Elements of Entomology," just finished. The family is divided into thirty-one 

 genera, (British,) and the species are familiar to all those who have observed the small 

 bee-like insect, hovering over the flowers in gardens or woods from spring to autumn. — En.
