 fuscous, and there are other well-marked characteristics. — A. H.

:]P>RACTICAL HINTS. 



Field Work for June and early July. 



By J. W. TUTT, F.E.S. 

 1, — The larvae of Pachnohia Jn/jierborea are to be found under moss 

 during early June, in firwoods where Vaainiiun wijrtillm grows 

 (Staudinger), but the larva feeds on crowberry and bilberry, prefer- 

 ring the former (Meek). 



2.— During June, the shoots of Li/simarliia should be collected for 

 larvfe of Oclcchia tnorosa. Wicken Fen is the best known locality. 



3, — At the end of June, the stunted plants of sea-thrift growing on 

 rocks on the sea-coast should be searched for pupje of .SV.s/(/ philantJii- 

 fnniiis. The larva hollows out the main stem of the plant, and, for 

 pupation, forms a silken tubular cocoon within the hollow. 



4. — The flowers of Silnw iiiaiitiina, growing in a little recess, about 

 10 feet across, among the rocks on the shore near Douglas (I. of Man), 

 of easy access, produced 105 Diantlioccia rocsia, 32 D. capsopliila, 

 4 Plusia indclirina, 12 KnpWwcia venomta, and many other insects, 

 during twenty evenings in June and July, 1876. The specimens were 

 captured without moving from the spot, indeed, I v/as sitting on a 

 stone most of the time (Birchall). 



5. — When larvae pupate in cork, be careful to isolate each one as it 

 prepares to bore, otherwise two or more are almost sure to enter the 

 same burrow, and only one (the last) will have any chance of escape. 

 G. -Webs of Porthcsia rlni/xorrJioea should be searched for early on 

 hawthorn. Mr. J. J. Walker informs us that he has this year observed 

 them in the Isle of Sheppey, after the species has been practically 

 absent from the district for nearly 20 years. 



7. About the beginning of July, before the healthy reeds overtop 

 the affected ones, look over reed beds for reeds having the top shoot 

 of the reed withered. About the end of July cut such reeds low 

 down. A circular scar will be observed well down where the larva 

 of Nonaiiiia (leminipuncta has gnawed through the reed-stem, except 

 the outer skin, in readiness for the emergence of the imago. 



8. — Place at the bottom of an old chip hat-box two inches of sand. 

 Collect the seed capsules of Silme iujiata, S. ccDiipcstris, etc., and lay 

 on the sand. Cover the top of the box with gauze by means of an 

 elastic band. Put in a few fresh capsules occasionally, and you will 

 breed Dianthncvia mmpersa, P. rarpophaiia and KKpit/irria vcnosata 

 (Hall). 



9.— Although Leitcauia strain iiii'o is best taken on the wing from 

 9 p.m. to 10 p.m. from about July Ist-August 1st, a drop of sugar 

 in the centre of a flower of the dwarf thistle, common on the side of 

 the dykes in the marshes, will frequently attract it. 



10. —The larvffi of Eupithecia .subninhrata (scabiosata) feed on the 

 flowers of Daucm carota in July. The larva of Spilodes palealis feeds 

 later in heads of the same plant.
