After this I made an expedition up the banks of tlie Teigu on the 

 Shaldon side, in order to examine carefully the plants of Pyrus tormi- 

 waZj's, wliich £^row there in some abundance. These plants need a little 

 scramble in order to get at them, but for this I was well repaid, by 

 finding the neatly made cones of an Ornix on the points of many of the 

 leaves. It was too late to find the larva?, but it is to be hoped that 

 another season will ascertain with certainty to what species this belongs. 

 On the same trees were the mines of L. torminella and L. corylifoliella, 

 both tolerably common. There were also abundance of wild cherry 

 trees, and these were examined (though from lack of time not so care- 

 fully as they deserved), the mines oi Lyonetia GlercJcella were common 

 on them, and on one leaf I found the folds of an Ornix, not a neat cone 

 as on the P. torminalis, but a fold as that made by Omix guttea. There 

 were no mines of any LUhocolldis on the cherry. Ou the Alriplex by 

 the river's bank were mines of Gelechia nceviferella, but the larvae 

 were gone. 



In the evening, sugar as usual was a complete failure, but on the 

 flowers of Linaria vulgaris two larvas of E. linariata were found, and 

 also Pteropliorus pterodactylus in plenty, and one P. acanthadactylus. 



September 23rd. Examined the alder trees. The only mines were 

 L. alnifoliella ; except a single example of what I believe to be L. 

 Frblichiella from Haldon. 



September 25th. Went to Whitewell on Haldon, for the purpose 

 of examining the trees of Pyrus aria, which are there found in plenty. 

 Ou these there were two species of Lithocolletis, one on the upper-side, 

 certainly L. corylifoliella, one on the under-side, probably L. torminella. 

 On none of the leaves did I sec any symptom of an Omix. 



September 26th. "Went to Newton by train, and from there walked 

 to Ashburton ; about two miles on the road I first found Litli. Bremiella 

 on the left hand side, and it was met with almost the whole way to 

 Ashburton. On the tojDS of the Vicia Sepium were also some curioua 

 pod-like galls, looking like the work of some Cecidomyia. L. Bremiella 

 occurred chiefly amongst the more sheltered plants, and I found one of 

 the jierfect insects asleep on a leaf, and since then others have made 

 their appearance, so that in Devon, like L. irifasciella, it is almost a 

 winter insect. The only other plants examined carefully in this walk 

 were Viburnum lantana and the little Poterium sanguisorba, the latter 

 again without any trace of a Nepticvla. 



At Toignmouth a specimen of Botys asinalis was caught at liglit,
