92 LIST OF INSECTS. 



S. tigrina. — Of frequent occurrence, and examples are often met with in our 

 entomological rambles during the summer months. 



S. viridula. — May be said to be common. It is very partial to the flowers 

 of the Marsh Thistle, (Carduus palustris,) in the Lewes and Newhaven 

 Levels, in July. It delights in the hottest sunshine. The beautiful green of 

 the abdomen, which is so bright in living specimens, generally fades into a 

 brown after death. 



Oxyeera trilineata.' — Rare. In my own garden in July. 



Nemotelus uliginosus. — Not uncommon in the Lewes and Pevensey Levels, 

 and frequents the flowers of Marsh Ragwort, (Senecio aquations,) in July. 

 It is a somewhat sluggish and inactive insect. 



N. pantherinus. — Not so common as the preceding, but associates with it, 

 and is found in the same locality and at the same period. Both species are 

 very beautifully marked insects, with their almost invisible transparent wings. 

 They appear to be invariably marsh species. 



Chrysomyia formosa. — Common. A very beautiful and distinct species, 

 occurring very generally in this district, and rather plentifully from June till 

 September. It is very fond of settling and basking on the leaves of shrubs 

 in hedges and gardens. 



C. polita. — Equally common with the last species; its habits are similar, 

 and may be found in the same localities. The <£ and 5 vary a little in 

 point of colour — from a golden green to a tinge of copper-colour, and having 

 the violaceous tinge in the female. 



Sargus cuprarius. — This common but beautiful insect is ornamented with 

 brilliant metallic colours. It is very inactive in its habits, and appears to 

 delight to rest on the foliage of plants, rather than on their blossoms. It 

 affects pleasure-grounds and gardens, and may frequently be seen in the 

 neighbouring lanes enjoying the sunshine, from June till August. 



S. nebeculosus. — Common in this district, but so closely allied to the last 

 species, that I almost doubt if it is not only a variety; its habits and the 

 localities it frequents are the same. 



S. bipunctatus. — Once taken near Ilford, in August, 1855, but it does not 

 appear to be so general as the two preceding species. It is equally beautiful 

 in colour. 



TAB ANLD^E.— Leach. 



Tabanus bovinus.—R&re, and by far the largest and most conspicuous of 

 the British Diptera. Taken occasionally on the Downs frequented by cattle, 

 near Bottingdean, Kingstone, and elsewhere in this district, in August and 

 September. 



T. autumnalis. — "Very common generally, and usually appears in the hot 

 months of July and August, and indeed throughout the autumn, from whence 

 no doubt its specific name. The Tabani are generally known by the names 

 of Breeze or Horse-fly. All the species are of a very strong and robust form. 



T. tropicus. — Less common than Autumnalis, although not of unfrequent 

 occurrence near Lewes and the immediate neighbourhood, in July and August. 

 Usually found settling on the ground in unfrequented pathways, enjoying in
