beetles, which had temporarily sheltered themselves behind the stems, and aban- 
doned them for more promising material at the first opportmiity. 
All the Xylophaga appear to eat largely while in the perfect state, and, unless 
they find a nidus for oviposition at once, commence to browse on any food at hand. 
I have found that during the past warm summer many species have emerged 
at the end of July, which do not usually become perfect until September, and then 
do not emerge before the next spring. Every season, probably, a small proportion 
is perfected early, as the majority have been during the past season ; the rest, 
following their usual habit, remaining till spring. What do these prematurely- 
developed specimens do ? 
In August I found Cryphalus binodidus engaged in oviposition just as they 
were in May ; and Hylurgus pilosus, Hylesinus crenatus and H. fraxini eating 
galleries, in each of which there was only one beetle, and, as the bark was not 
such as they usually choose for oviposition, and there was no sign of that process 
being carried on, I conclude that they intend to hybemate in these galleries, and 
to postpone oviposition until spring. Though HyUrgus piniperda and Scolytus 
destructor had almost all emerged, I have had no opportunity of tracing them 
further. 
In Hylesinus and CryphaUs UnodAdus, I always find a pair of beetles in each 
burrow. During the entire period of its construction, Hylurgus pilosus is often in 
pairs, but the male usually leaves before oviposition is complete, though with this, 
as with the former species, pairing occurs in the burrows, and probably only there. 
The economy of Hylastes palliatus is similar. In the burrows of Hylurgus pini- 
perda, I have rarely found both beetles, and then only when the burrow was jusb 
commenced. Of Scolytus destructor, I have only found a pan- in a burrow on one 
occasion, and am inclined to doubt whether the male often enters the burrow at 
aU. In my former notes, p. 140, line 10, the word "side" should be "end" or 
"far end." — T. Algeknon Chapman,* Abergavenny, Octoler, 1868.
