NOtES ON THE BlUtlSll LONGICORNES. 30l 



occurs on poplars, aspcus and alders. It is a northern insect, most of the 

 specimens in collections coniinjf from tiie Manchester district. It has 

 been taken at Ke^jton and in Sherwood Forest. It was taken this 

 year and last at Kaniioch, the s})ecimens having been given to 

 Mr. Lewcock. Our third species, Sapenla pnpalnca, L., is the 

 smallest of the three. It is a pretty little insect, mottled with 

 yellowish })ubescence, and has the antennte ringed with white, as in om* 

 A(iapanthixi. It is said to be found on poplars, willows, sallows and 

 aspens ; I have only found it on the latter. I have taken it on 

 Wimbledon Common in numbers, and sparingly in Darenth and Monk's 

 Woods. It is a local insect, but not uncommon in many localities as 

 far north as Lincoln ; it is not, however, found farther north. The 

 female deposits her eggs in the thin branches or saplings of the 

 aspen, an oblong swelling of the twig is the result, in which swelling 

 the insect passes its metamorphoses. There is a very beautiful show 

 case in the Insect Gallery of the Natural History Museum, illustrating 

 the metamorphoses of this beetle. I have found all the as})en trees at 

 Chiddingfold ])ossess these swollen knobs, and have opened several and 

 found tile larva, but I have not seen a smgle perfect insect this year. 

 JMr. Blatcli mentions, in the Ent. Mo. Ma'/., for November, 187i*, that, 

 although this beetle was fairly common in Bewdley Forest in 1878, in 

 187!) he never saw a single specimen. I should say the explanation in 

 both cases is that this insect takes two or more years to complete its 

 metamorphoses, and thus in some years it occm's in abundance, and 

 in others very sparingly, if at all. 



The next genus, Tctrops (Pohjopsia) consists of small beetles, which 

 have the eyes completely divided. Tctrops pracusta, L. {iistulata, Hag.), 

 our one species, is the smallest British Longicorne. It is very like a 

 small Telcphorm in appearance. The head, thorax and apex of the 

 elytra are black, the rest of the elytra are yellow. It is to be found by 

 beating hawthorn blossom, and may be taken towards evening, Hying 

 over the blossoms. It is common and generally distributed from the 

 Midlands southwards, but is rarer farther north. I have taken it at 

 Penge and in the New Forest, etc., by beating hawthorn blossom, and 

 as late as July on Umbellifers at Chiddingfold. 



Stennstolaferrea, Schr., is an elegant insect of a steel blue-black 

 colour. It is found on flowers, and by beating limes, hazels, etc. It is 

 both local and rare. It is recorded from Matlock and Repton, and the 

 Manchester district. Mr. Gorham has taken it in Lord's AVood, 

 Southampton. Last year, Mr. Janson took a specimen in Derbyshire, 

 by evening sweeping, in June. 



The genus I'lnjtoecia is closely allied to SUmostola, but differs by 

 having raised lines on the elytra. Our only si)eeies P/ii/torcia ci/Uit- 

 (Irii-a, L., is a black insect covered with grey pubescence, the anterior 

 legs are yellow. It is also a rare and local insect, and is found on 

 flowers, and is to be obtained by beating hazels. The larva feeds in the 

 stems of the latter. I took a single specimen by sweeping, at Dorking, 

 and I swept it in some numbers in a glade at ^Monk's AVood. It is 

 recorded from various localities in the London district, also from 

 Cambridgeshire, Leicestershire and Kepton. 



The last Longicorne in the catalogue, Obera nndata, L., is one of 

 the flnest, and certainly one of the most sought after and jirized. It is 

 a flue beetle, with grey elytra. The head and antennie are black, and
