308 THE CANADIAN ENTOMOLOGIST. 



The Chrysomelidae were not represented except for a number of 

 Calligrapha scalaris and larv?e which were swept from the low Alnus 

 iiicana in the pasture. 



Tenebrionidîe. — Alobates pemisylvanica, Iphthiffius opacus, Tenebrio 

 tetiebrioides, HypopJiloeus paral/elus, and Xylopinus saperdioides were 

 taken commonly under bark or on the slab piles. Upis cera??iboides was 

 common, flying and on slabs. One specimen of Platydema americanum 

 was taken. Arthro?nacra œîiea was beaten from Alnus in large numbers. 



Of the Melandryidse, Penthe obliquata, Synchroa punctata^ Melan- 

 drya striata^ Phloetrya liturata, Eustrophus bi/asciatus, Onhesia castanea 

 were taken on the logs or slabs. Enchodes sericea was beaten from the 

 dead branches of a large rock maple, and also found on a log of this tree 

 at Wales, Maine. Salpingus virescens and Pyt/io planus were both taken 

 on one occasion under bark or slabs. Dit y lus cœr ulcus was captured a 

 few times on the logs and was also seen flying in the daytime. Dendroi- 

 des canadensis and concolor were both taken ; the former under bark and 

 by beating, the latter by beating maple sprouts in a wood clearing at Wales. 



Tofnoxia lineella was seen on the trunk of a decayed elm, and a single 

 specimen was captured while unguardedly trying to rid itself of a large 

 mite. Several specimens of this species were taken several years before 

 on a dead tree in tne woods. 



Hylobius pales was sometimes present in large numbers especially 

 under bits of slabs that had fallen to the ground. Pachylobius picivorus 

 was less common, in fact rare. Pissodes affinis, strobi, and a single dubius 

 were taken from the piles of lumber ; affinis was the most abundant. 

 Mononychus vulpeculus was swept from the flowers of the blue iris near 

 the brook. 



Large numbers of Scolytidse were taken flying in the late afternoon. 

 The spruce logs were very badly riddled just beneath the bark by some 

 species of this family. Among those that have been identified are Den- 

 droctonus valens, Hylurgops pinifcx^ Hylcsinus aculeaius, Xylotcrus bi- 

 vittatus and Hylastes caver?iosus. 



Taking into account the undetermined species and a few specimens 

 that may be in alcoholic material not yet examined, the number of species 

 taken in and about the mill-yard will not fall much short of 125 ; many of 

 them which are rare under ordinary conditions are here abundant, while ex- 

 cessively rare species appear with gratifying frequency. If it were possible 

 to collect in this yard frequently from June ist to August 15th, I feel sure 

 that the results would be surprising. Any collector who can visit a place 

 where lumbering operations are carried on, even on a moderate scale, will 

 be amply repaid.
