Coleoptera at Falmouth. — I spent a week at Falmouth, from March 8th to 15th, 

 and endeavoured, during this time, to work the district for Coleoptera. The east 

 wind, even in tliis extreme south-west corner of England, had, however, lost none of 

 its bitterness, and the only sheltered place I could find was the sandy beach under 

 the low cliffs to the westward of Pendennis Castle. Here I had the pleasure of 

 seeing Aepys marinus alive for the first time, under stones at high water mark, but 

 it required a lot of working for, and I succeeded in finding only three specimens. 

 An even more welcome sight was that of the tiny and active Actocharis Readingi 

 (hitherto, I believe, recorded as British from Plymouth only), of which a couple of 

 specimens were found running on the under-sides of large stones sunk in the sand, 

 in places where a little trickle of fresh water came down from the cliffs above. 

 FMlonthus fucicola was common here (also at Mylor, on the shores of the harbour), 

 accompanied by the var. variolosus of P. xantholoma, and many of the usual littoral 

 StaphylinidcB, &c. In the lanes, almost the only beetle to be obtained was 

 Phloeophagus ceneopiceus, which occurred plentifully in old stumps in the hedges : 

 its favourite food appeared to be ash, though I found it also in oak, hawthorn, and 

 elder, as well as traces of its former presence in holly. 



A good looking piece of marshy ground at the head of a large piece of fresh 

 water near the shore, about a mile west of Falmouth (called Swan Pool), produced 

 nothing better than Pcederus fuscipes. 



A few unset specimens of Phloeophagus ceneopiceus are at the service of any 

 Coleopterist who may wish for the species. — James J. Walkek, H.M.S. " Cherub,"

Description of the nymph of Psylla mali, Schmidtberger. — Pale green, shining* 

 with a fringe of pale hairs round the front of the head, costal margin of the elytra- 

 lobes, and apex of the abdomen, those round the latter longest. Head : anterior 

 margin flattish-convex, crown flattish-convex, with a minute fovea on each side of 

 the centre between the eyes. Eye-caps whitish, through which shines a somewhat 

 round, small, dark spot. Antennae greenish-yellow, apex black. Pronotum with two 

 fovese in front on each side of the centre, and another pair near the posterior-margin, 

 the latter larger than the former. Elytra-lobes whitish, opaque, with a small notch 

 on the costal margin at the extremity of the suture. Legs green, apex of the tibiee 

 and claws dark brown. Abdomen, in one sex, somewhat convex above and under- 

 neath, contracted at the base, whereby the acute extremities of the elytra-lobes 

 overhang the sides ; in the other sex somewhat ovate ; extreme apical margin very 

 narrowly clear brown in both sexes. 



The insect in this state is to be met with very commonly on apple trees, generally 

 from the middle to the end of May. — John Scott, Lewisham : Feb. 17th, 1886. 



Description of the nymph of Psyllopsis {Psylla, Foerst.) fraxinicola. — Pale

 slightly reddish-brown ; antennae pale yellowish, apex black. Elytra-lobes pale 

 greyish-white, costal margin with a fringe of short hairs. Abdomen somewhat
