'20 THE CANADIAN ENTOMOLOGIST. 



On the 2 1 St, at the west end, captured a freshly hatched male; found 

 no larvae; leaves of weed showing little signs of being eaten. 25th, 

 same place ; butterflies plentiful ; freshly hatched mingling with old broken 

 ones; took a fresh female. East on the 27th; butterflies not plentiful ; 

 saw a few larvge nearly full fed. 28th, west; not so plentiful as on the 

 25th. From the 2nd to the iSth of August, I was in the vicinity of 

 Brantford — 25 miles west from Hamilton ; there were {ew D. archippus 

 to be seen, but all were fresh ; yet there was an abundance ot asclepias. 

 On the 20th, was at the west end ; larv?e scarce ; saw one not half an inch 

 long ; took one full fed, which suspended that night, and pupated the fol- 

 lowing night ; there were very few archippus about the milk-weeds, which 

 were now four and a-half and five feet high. From the ist to the 17th of 

 September I was 16 miles south of hefe; there I saw several fresh archip- 

 pus, but not a single stalk oi asclepias. On the 21st was at the west end ; 

 archippus had completely deserted the milk-weed ; I saw some feeding 

 in a garden some distance away. My impression has been for a good 

 while that the butterflies care but little for the milk-weed to feed at ; that 

 they are there for breeding purposes principally ; that they are but light 

 feeders, with a great fondness for loitering in open woods, where there is 

 apparently nothing for them to feed on. My last observation was made 

 on the 15th of October ; the milk-weeds were still green at top, but the 

 lower leaves were all decayed. I have seen no butterflies since the 21st 

 of September. J. Alston Moffat, Hamilton. 



SOME COLEOPTERA NEW TO COLORADO. 



Dear Sir : Dr. John Hamilton has been good enough recently to 

 examine some Coleoptera which I collected in Custer County, Col., and 

 among them he finds five specimens new to the State List. One, Ditylus 

 obscurus, was obtained in the eastern portion of the county, the other 

 four are from near Swift Creek, at 8,000 to 8,500 feet altitude, and are as 

 follows : Aphodius brevicollis — which Dr. Hamilton says was previously 

 known only by a single specimen found in Nebraska ; Hister Harrisii, 

 Kirby ; H. subopacus, Lee. — three specimens obtained ; and Lebia 

 vivida, Bates. Among my beetles from Eastern Custer Co. was also 

 an example of Fityophagus verticalis, which Dr. Hamilton says was 

 previously known by a single specimen only.
