1912] 109 



conjunction with the records from Pembrokeshire and Grlamorgan- 

 shire, we get for the south coast of Wales a total of 200 Heteroptera 

 and 80 Homopfem, which is probably a fair proportion of the species 

 that actually occiu' there. 



The whole of the coast of Carmarthenshire consists of sandhills, 

 which extend from Llanelly in the east to Ferryside, where they are 

 interrupted by the estuary of the Towy ; they are continued on the 

 other side of the estuary, and run on uninterruptedly to Pendine, near 

 the western boundary of the county, where cliffs form the coast line 

 and so terminate them. This western division gives an unbroken 

 stretch of sandhills for al)out six miles. Unfortunately, however, it 

 is somewhat difficult of access, the nearest railway station being some 

 eight or nine miles from Pendine. My collecting was done chiefly in 

 the neighbourhood of the town of Carmarthen, and on the Burrows of 

 Kidwelly, Ferryside, and Pendine. There is an interesting piece of 

 bogland near Sarnan, on the Carmarthen side of the village, which 

 yielded a few good species ; but it is ground that needs wary working, 

 as it is infested with adders, of which I saw, on one occasion, five 

 sunning themselves together on one small hillock. Almost all the 

 water-bugs were taken at Pondside, Carmarthen. This is really a 

 tributary of the Towy, but in the neighbourhood of the town its course 

 has been banked up, so that it now runs many feet above the level of 

 the river. This was for the purpose of supplying water power to some 

 tin-plate works which are now derelict. This part of the stream runs 

 east and west, and therefore in its raised position it is exposed to the 

 direct rays of the sun all day long. Possibly for this, or for some 

 other reason, it is prolific in certain species of aquatic Hemiptera. My 

 collecting was done almost entirely in the month of August and the 

 first week in September. 



The species marked (*) ai-e recorded also from Glamorganshire, 



and those marked (t) from Pembrokeshire. Besides these, 52 other 



species of Heteroptera have been recorded from Grlamorganshire, and 



14 Heteroptera and 3 Homoptera from Pembrokeshire, which are not 



in my list. 



HETEROPTERA. 



Pentatomid^. 



Thyreocoris scarabmoides, L.* : fairly common in 1906 amongst Ononis, 

 which thickly covers a large part of the Pendine Burrows. Dolycoris bac- 

 carum, L. : Ferryside ; larva in August amongst Ononis. This larva may be 

 easily distinguished by its pilose sitrface. Fiezodorus lituratus, F. : common 

 on furze bushes in March and August. Zicrona ccerulea, L.*: one specimen 

 amongst long grass in the boggy grotmd near Sarnan.
