A. mercuriaJe, Cliarp. — in company with Mr. McLaclilan I took the species in some 

 numbers in the locality pointed out by him, where he had found it the previous 

 year, and a few days later it was observed rather more commonly near Emery Down. 

 Mr. McLachlan's suggestion that it is probably not uncommon in the New Forest 

 (Ent. Mo. Mag., vol. xx, 1st series, p. 255) will no doubt prove correct. Pyrrho- 

 soma minium, Harris — common. P. tenellum, Villers — common at some of the New 

 Forest bogs ; the form of the $ with black abdomen is not infrequent. Erythromma 

 najas, Harris — a good many examples seen at an old brick hole near the Thorney 

 river, flying over water lily leaves. 



With regard to the several interesting dragon-flies which are 

 apparently exclusively confined to the south-western counties, and 

 which used to be taken by the old collectors, Ischnura pumilio, V. de 

 Lind., is the one which has longest eluded the investigations of more 

 recent workers, and seems still to await re-discovery. It is evidently 

 much more fastidious about the conditions of the water it inhabits 

 than I. elegans, which lives almost anywhere, and it is said by Dr. Eis 

 to be found in Switzerland only at ponds and waters with a clay bottom, 

 and to avoid peaty waters. Those searching for I. pumilio should also 

 bear in mind that the flight of some dragon-flies is of very short du- 

 ration. According to Ris, I. 2JU')}nlio in Switzerland flies for a short 

 time at the beginning of June, and soon vanishes to re-appear again 

 in August. 



Amongst the Triclioptera the most interesting species found in the New Forest 

 was Phryganea minor, Curtis, which occurred abundantly about a dried-up pond in 

 one of the enclosures by sweeping the herbage in the evening, and by disturbing 

 them from the chinks of the bark of the surrounding trees during the day. Only 

 one example was found away from this main locality ; nearly all taken were females. 

 P. varia. Fab., was also taken, and one of the larger species seen but not identified. 

 Limnophilus luridus, Curt., is a very characteristic insect of the Forest. The other 

 members of the genus Limnophilus taken were L. grixeus, L. auricula, L. rhombicus, 

 L. centralis, L vittatus, and L. sparsus. GlyphotceHus pellucidus, Oliv., was not 

 uncommon. Isolated examples of Sericostoma perxonatum, Spence, occurred here 

 and there, one J being very curious in having hoary patches on the fore-wings ; no 

 difference from the normal form seems to exist in the genitalia as far as I have been 

 able to examine these. Goera inlosa, F'., was represented by a few rather small 

 examples. Leptocerus bUineatus, L., was the only noteworthy species of its family 

 found in the Forest. Holocentropus dubius, Ramb., occurred at a pond near Ring- 

 wood. These are the more important caddis-flies noticed. The Hampshire Avon 

 must be a fine stream for Trichoptera, but when it was visited the early summer 

 species appeared to have already passed off. 



In the other Neuropterous groups there is little to record. Only a single 

 Rapliidia {R. notata. Fab.) was seen. Hemerobiiis concinnus, Steph., was disturbed 

 occasionally from fir trees when these were being knocked for Phryganea minor. 

 Ckrysopidee abounded, but they appear to belong to the ordinary species. Panorpa
