^0 THE ENTOMOLOGIST. 



Ellopja prosapiaria ; a fine male Pixcilocamjm popidi came into a 

 lighted room, 



A walk in the woods resulted in no single specimen of the 

 genus Hi/hernia, though I saw two Oporahia dilutata. 



Larvae of liwnia luteolata and Abraxas sjjlvata were seen, both 

 on elm trunks ; also ova of Tlimera pennaria. 



Observations of the later flights of Pierids have shown me 

 the following facts that may be of interest : 



They emerge in the spring in the order )iapi, rapce, hrassicce, 

 but napi apparently takes less time over its generation than the 

 other two. liap(t and hrassica preserve their relative order, and 

 put in three flights in the year. Napi gains on them, appears first 

 in the second and third flights, and this year put in a partial 

 fourth flight synchronous with the third appearance of hrassicce. 



The third flight of napi is of the napcete pattern, though by 

 no means always strictly ab. nap(e<e. 



The fourth flight is smaller in size, and the green veins 

 become more pronounced again. 



The third flight of rap(E is chiefly remarkable for yellowness 

 of the ? ; and that of brassicce for ? ? with heavy black mark- 

 ings, and both sexes with very dark scales dusted over the 

 under sides of the hind wings. 



The Pyralides were fairly numerous, but produced nothing 

 at all unusual. 



Aglossa pinguinalis is common in farms all along the line, 

 and is one of the most frequent trophies in spiders' webs in out- 

 houses. These webs have now been left undisturbed for two 

 years, and were a great help in making lists ; thus, I have not 

 vet seen a living Gonoptera libatrix in this country, but no cob- 

 web is complete without one. 



Pyralis costalis I found only in one dug-out near Fricourt, 

 ^'here there were eight perfect specimens. 



P. farinalis is fairly common round Corbie, but I have not 

 Been it elsewhere. 



The genus Scoparia has been poorly represented. 



Early in the year, on the Somme, dubitalis was the only 

 abundant species ; ambigualis was common, and cemhra dis- 

 tinctly uncommon. 



In Artois I found ambigaalis abundant, and saw a few 

 mercurell'i. 



Near Corbie I took a very worn insect that appeared to be 

 Nomopliila noctuella. It is common near Souchez. 



Pyrausta purpuralis and P. ostriiialis were very common in 

 the south and common in Art jis. 



P. ccspitali'i was common in Artois, but not in the south. 



P. olivalis, common on the Somme. 



Eurrhypara urticata occurred everywhere, but not in large 

 aiumbers.
