Besides Yenilia maculata and the other moths mentioned in the above lines, 

 Macroglossa bombyliformis, stellatarum, Sesia culiciformis, spheciformis and 

 apiformis occur in May, as also do Saturnia carpini, Thyatira baiis, 

 Dianthcecia cucubali and Stauropus fagi. 



The Hawk Moths, Smerinthus populi, Mice, ocellatus, Sphinx ligustri (end 

 of the month), and Chcerocampa porcellus also emerge in May. It is, of 

 course, unnecessary to do more than merely mention such well-known species. 



Among the Geometrina flying in May, we have the common and well-known 

 Brimstone Moth (Rumia cratcegata), which keeps out all summer, the Speckled 

 Yellow {Yenilia maculata), the Pale Grey (Selenia illustraria), the generally 

 distributed Scalloped Hazel (Odonlopera bidentata), which the young naturalist 

 will probably find at rest on oak and other trees, or capture at light. The 

 ochreous and not very common Waved Umber (Hemerophila abruptaria), 

 which looks very much like a chip of wood as it sits on palings with all its 

 wings expanded, the rather scarce Tephrosia consonariaand punctulata, Ephyra 

 porata, punctaria, trilinearia, omicronaria, orbicularia, and pendularia. 



The whitish, fuscous dusted, Cream Wave (Aeidalia remutata), with pale 

 fuscous band, and in size the same as the common A. aversata, comes out at 

 the end of the month. It is generally distributed, but cannot by a long way 

 be considered abundant everywhere, although it is plentiful in some localities. 

 The Common White Wave (Cabera pusaria) also appears in May and its 

 related species the rare C. rotundaria and the abundant C. exanthemata 

 come out. Pusaria and exanthemata keep on the wing all summer. 



The other May Geometrina are the Clouded Silver (Corycia punctata), C. 

 taminata, the Latticed Heath (Strenia clathrata), the Brown Silver Line 

 (Lozogramma petraria), the Common Heath [Fidonia atomaria) , the Bordered 

 White (F. piniaria) , the rare and local Yellow Belle (Aspilates citraria), the 

 Common Clouded Border (Lomaspilis marginata), which keeps out until the 

 end of July where sallows are plentiful, the rare Pachycnemia hippocas- 

 tanaria, the uncommon Netted Pug (Eupithecia venosata) and others of the 

 genus, as consignata, pulchellata, plumbeolata, satyrata, castigata, irrignata, 

 indigata, nanata, vulgata, assimilata, exiguata, and coronata ; together with 

 Lobophora sexalista, Ypsipetes ruberaria, Y. impluviata, Melanippe biriviata, 

 M. iwntanata, Coremia propugnata, C. ferrugaria, C. unidentaria, Scotosia 

 certata, Cidaria russata, C. suffumata, and C. silaceata. 



On oak trees we may find this month the caterpillars of Catocala promissa 

 and & hispidaria, and on hawthorn those of Hemithea thymiaria, and (in its 

 localities) Pieris cratcegi* 



Omitting mention of such species as were alluded to last month, the follow- 

 are a few of the larvee to be found in May ; — * P. pilosaria, on oak ; N. goth
