illustrations of the new characters and explanations in detail of the 

 new terms used, so that the arrangement will be clearer and easier to 

 understand. Although detail-figures are undoubtedly of the greatest 

 importance, still when so many new genera are erected " Habitus- 

 Bilder" would be very welcome. The new system has all the charms 

 of novelty, but it will be easier to appreciate it at its true value when 

 all the genera have been considered and the whole arrangement 

 reduced to uniformity.

Field Work for June. 



By J. C. DOLLMAN. 

 1. — In late June carefully search seed-pod heads of cuckoo-flower, 

 garden -rocket, etc., for larv;e of Kurhlo'c ranUoiiuics. Examine those 

 parts where the growth of seed-pods seems irregular, which will be 

 owing to the feeding of the larva, and the latter will be found closely 

 imitating the growth there. 



2. In examining buckthorn for larvjp of Gonepteryx rhamni, place 

 yourself so that the sunlight faces across the leaf, showing the 

 shadowed side of the larva, when it is at once discovered. Otherwise 

 it so exactly resembles the mid-rib along the centre of the leaf (where 

 it rests) that many will escape notice. 



3. — An umbrella is preferable to a tray in beating for Zciihi/nift 

 betulae, as it can be fitted into the structural irregularities of the black- 

 thorn more successfully. 



4. — The low branches of oak, with thin growth of foliage, on 

 isolated trees, will often prove the best to try for larv;e of Zephyr u,^ 

 (jtierciis. Search the tray carefully, as the half-grown examples imitate 

 the fallen bud sheaths exactly in colour. 



5. — The larv* of HyUqihUa bicolorana are most frequently found 

 in thickly-grown, rich, green, oak foliage. It is best to rear each 

 specimen separately, or the pupation of the earlier ones will be 

 disturbed by those still feeding. 



6. — Do not chase the imagines of XeweopJn'la niHsKia but mark them 

 down and put the net over an insect, holding up the bag end of it. 

 The specimen may thus be taken unbroken. The S insects will often 

 start from the low growth by half a dozen at the time; on such 

 occasions search for the ? . 



7. — Be careful not to pass by the nest of Lachuh lanrstris, mis- 

 taking it for spider's web, which it closely resembles in the earlier 

 stages of the larva. 



8. — The young larva? of Malacosoma neu atria lie on the top of low 

 hedges, sunning themselves, in a group. Before making any attempt 

 at capture slip a net, cap, or sheet of stiff paper below the community, 

 as on being disturbed, they immediately wriggle from their position 

 with the activity of lizards, and drop to the ground. 



9. — Beat the low boughs of ever-green oak for larvie of Asphalia 

 diluta, and, if found, keep industriously to the tree or trees. Also 

 search leaves spun together. This larva is best fed separately, as it
