102 THE CANADIAN ENTOMOLOGIST 



frequently the case, find no ground soft enough to bore into, it pupates 

 wherever it may be when the change can no longer be deferred, and this 

 occurs mostly under some leaves. Some of these exposed pupae when 

 collected in April will produce moths, notwithstanding the low tempera- 

 ture to which they must have been subjected. 



Fterostichus, Vol. XVI., 73. — I there enumerated sixteen species taken 

 in this vicinity ; four others have since been discovered, and three have 

 been transferred from Evarthrus, making a total of twenty-three. 



P. vinctus Lee. — This species is semi-mountainous, inhabiting under 

 stones on the sides of steep hills where the soil is moist and friable. 

 Though not gregarious, when found several individuals may be taken in 

 the same vicinity. Near the city, it must soon become extinct. 



P. ufiicoior Say. — Of this rare insect I have only taken one specimen, 

 and Mr. W. Klages took another. It must be sought for in mountainous 

 places. 



P. lachrymosus Newm. — Occurs with adoxtis, and in about equal 

 numbers ; without care, from their great resemblance, they may easily be 

 confused. Their future must be the same. 



P. coracinus Newm. — On the south side of the Ohio, on the rugged 

 sides of the hills yet in a primitive state, this species occurs abundantly. 

 Certain individuals may readily be confused, some with stygicus and 

 others with relictus, according to the greater or less development of cer- 

 tain characters at the base of the thorax. It is not likely to soon become 

 extinct. 



P. ta?'taricus Say, for form strenuus Lee. — Specimens were taken in 

 the city, in June and July, at electric lights, but it did not occur to me 

 elsewhere. 



P. patruelis Dej. — This little species inhabits a small swamp, in- 

 accessible, except for a short time during the dry season. It is found 

 about the roots of bunches of grass. When this swamp shall have been 

 drained, this species will probably be extinct here, since no other primi- 

 tive swamp remains in this vicinity. 



P. femoralls Kirby. — Three specimens of this small species were 

 taken once, but the habitat was not observed, though probably it is the 

 swamp mentioned above. 



P. Hainiitoni is much more widely distributed than was at first known. 

 It occurs at a distance from the city on the sides of many of the hills in
