240 THE entomologist's ijecord. 



Macaria Uturata, Bnpalns piniaria (abundant), Aspilates strigil- 

 Inria and Dianthoecia carpophaga (one) were observed. The rest of 

 the party arrived at 3 p.m., after which the above-named species were 

 taken more or less commonly during the afternoon, the only notable 

 addition being Acidalia sfrnminata. After tea, dusking in Steer 

 Lane resulted in swarms of Gldarin falrafa, a few Angerona 

 prunariii, one Asthena liUeata, Cidnria svffnmnta (very worn) and 

 Hypsipetes sordidata. — L. J. Tremayne and L. H. Prout, F.E.S.

Field Work for September and October. 



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



1. — On the second Saturday in September, we could, by seeking 

 after dark with a lantern, see the larvae of FAipithecia succenturiata in 

 twenties on the upper parts of the ragwort plants, whilst during the 

 •day time they are only to be found on the lower portion of the plants, 

 on or amongst the twisted dead leaves (Gregson). 



2. — The larva of Plati/pti'n/.r Itarpagnla (sinda) is to be obtained 

 in Leigh Woods, near Bristol, by beating, in the middle of September. 



3. — The larvfe of P/iorodi'sma sinaraiidaria are to be found on the 

 Essex salt-marshes, in September, by searching Artemisia niaritinia. 

 'They are strange little atoms, with scraps of the food-plant gummed 

 •over their bodies. 



4. — The larvae of Demas corijli are to be beaten from beech, in the 

 middle of September. 



5. — The larva of Platijpteri/.v falcataria is common in September 

 and October, on birch and alder. The larva is conspicuous on Alnus 

 fjhitinofta, owing to its bending the sides of the leaves upward with 

 a few silk strands. If not within this tent, it may usually be found 

 •on the upper side of some neighbouring leaf. 



6. — The imagines of Thera finnata are to be taken, in September 

 and October, on the boles of fir and larch trees, just out of pupa. 



7. — In September, search the flowering heads of grass growing in 

 •clearings in woods, for Citria flarago, C. fulvago and other a.nti\mn-al 

 Noctuid moths. 



8. — The larvffi of PJto.ropterg.v derasana are easily detected on 

 buckthorn, in September, by the leaves being folded over and fastened 

 together the whole extent of the leaf. They remain in the larval 

 state till spring, and then, after wandering about for a day or two, 

 pupate in rough cork. 



9. — The larva of Carpocapm Juliana feeds on acorns in September, 

 and is full-fed about the time that the acorns fall. 



10. — During the autumn, collect the common beech mast for the 

 larvae of Carporapsa groxsana. The full-fed larvfe avail themselves of 

 •cork and rotten wood in which to bore. They remain during the winter 

 as larvte in the cocoons, and often go over two winters in this 

 condition. 



11. — The larva of Catoptria neimdana feeds in the seed-heads of 

 Aster tripnliuiH, and is full-fed towards the end of September. 



12. — The larva of Catoptria decolorana feeds iu the seed-heads of 

 golden-rod, in September and October.
