108 THE ENTOMOLOGIST. 



of M. var. herta. But the Ombla valley was like an oven, and I 

 was glad to find a man with a conveyance, and I engaged him 

 to drive me to Gravosa, whence the tramway took me back to 

 the comfortable Hotel Imperial at Eagusa. This brought to an 

 end my brief entomological experiences in Dalmatia, for the 

 plans I made to return later on for more M. var. herta were 

 not carried out.

AN UNRECORDED APPLE SAWFLY IN BRITAIN 

 {LYGMONEMATUS M(ESTUS, Zaddach). 



By Fred V. Theobald, M.A., F.E.S., Hon. F.R.H.S., &c. 



The larvae of Lyg&onematus mcestus, Zaddach, were sent me 

 in 1911 and 1912 from two places in Hampshire (Steep and 

 Froxfield), and from Berkshire (Mortimer). In all three cases 

 they were found feeding on apple foliage. I also found a small 

 colony on a " Worcester Pearman "at Wye in 1907, but was not 

 then successful in rearing the insect. 



The larvae were sent me from Steep by Mr. T. E. Crompton, 

 who found them in an orchard on June 5th, 1911, and on June 

 10th he sent me another batch found in an orchard at Froxfield, 

 which were considerably smaller than those first sent. At Steep 

 only a single branch of one tree was attacked and completely 

 defoliated. At Froxfield they were much more plentiful, and 

 were stripping the trees in typical sawfly manner. 



The first ones pupated on June 13th, and the last on July 

 22nd. Some of them pupated in the soil of the breeding-jars, 

 others on the surface of the soil, and several amongst the 

 damaged foliage. Those in and on the soil covered the dull 

 yellowish silk of their cocoons with fine particles of earth ; 

 those on the foliage had a thick cocoon of a pale, dull yellowish 

 silk. The adults hatched out from April 20th to May 5th in 

 1912. 



The colony from Mortimer, twenty in number, were found on 

 a " Mother " apple, and were sent me by Mr. J. D. Lake on 

 June 14th, 1912. These have pupated entirely amongst the 

 foliage, making similar cocoons to those that pupated amongst 

 the leaves in the previous year. The larvae are very marked in 

 appearance. The adult larva is apple-green, with a small, 

 somewhat irregular, black spot on each side of the first four 

 segments, and a large round black spot on each side of the next 

 seven segments, numerous small black specks on the first four 

 segments, and some on the sides of the others. Head green, 

 with black eyes. Legs green. Length, 12 to 125 mm. A few 

 specimens showed a more yellow tinge. Those under observa-
