amber colored, with the anterior end somewhat more opaque. 

 The wood around the eggs, as usual, is discolored. Sometimes 

 there is but a single slit, sometimes but a single egg, in cases 

 where the parent had evidently been disturbed. Sometimes a 

 double pair are found close together." I received similar punc 

 tures also from Dr. Lintiier, from Pennsylvania, March 29, 1877, 

 and have also described in my notes punctures similar to the 

 above, which, however, are confined to a single crescent, differ 

 in the number and size of the eggs,- and undoubtedly are deposited 

 by some closely allied but distinct species. I introduce for com 

 parison Mr. Marlatt's figure of the eggs and punctures which ac 

 companied his first careful description of these, and his original 

 identification of the author of the slits. I also reproduce figures 

 of C. taurina and C. bubalusto bring out the imaginal differences 

 between the two species which are so easily overlooked.* C. 

 taurina is now to be associated with the egg-punctures which 

 have previously been assigned to bubalus by most writers on this 

 insect, following my reference to it in the Missouri report. I 

 also here reproduce my original figures of the egg-punctures, 

 preliminary stages, and adults, which illustrated my original 

 article. 



Professor Riley, under the head of " Notes from ' Sunbury,' " 

 showed a young sycamore tree transplanted on his grounds in a 

 perfectly healthy condition last spring. In the course of the 

 summer this tree was girdled by Chrysobothris femorata, the 

 eggs of which must have been laid in the summer. The pupae 

 were all formed and the beetles will issue next spring. He also 

 showed a yearling shoot of ash which had sprung up from an old 

 stump that had been cut down the present season. It was ovipos 

 ited upon by Trochilium syringce the present summer and the 

 adults began to issue the first of October. Both of these species, 

 then, are sometimes shorter-lived in the larva state than is usually 

 supposed. 



Mr. Schwarz stated that he had noticed the adults of Trochilium

 Entomology, have appeared in Insect Life, Volume vn, No. i, pp. 8-14,
