7-toothed (6-notched) on the very broadened and circular apical mar- 
gin, brownish. Other trophilight colored. Spiracles somewhat raised,. 
situated on side posteriorly of prothoracie segment, and on sides of 
segments 5 to 12, those on 11 and 12 situated higher up on dorsum and 
more removed from the lateral margin. Three pairs of short hook-like 
true or thoracic legs; and five pairs of fleshy prolegs, on segments 7 to 
10 and terminal joint of 13. 
ANote.—The segment which is called a terminal joint of segment 13 
may perhaps be regarded as the thirteenth segment. In this case the 
slightly hood-like or flap-like portion which projects over it from the 
twelfth segment would necessarily be regarded as a posterior develop- 
ment of that segment. 
Described from 3 specimens. Color noted in life. Arizona. The 
spécial organs described by Mr. W. H. Edwards, in his second volume 
of the Butterflies of North America, as found on segments 11 and 12 
of the larva of Lycena pseudargiolus, are also present in the above 
larve on Atriplex. The median transverse opening on 11 is very plain, 
but the two retracted tubes on 12 do not show as plainly as figured by 
Mr. Edwards. These latter show very much more plainly in lyezenid 
larve which I have taken in southern New Mexico on mesquite in 
May. —C. H. TYLER TOWNSEND. 
Honey Adulterations.—There has been in the past much differ- 
ence of opinion among chemists and beekeepers concerning the detect- 
tion of honey adulterations by chemical methods.. To obtain more 
definite information on the subject Professor A. J. Cook recently had 
samples of a large number of kinds of honey analyzed by Professor H. 
W. Wiley of the U. S. Department of Agriculture, Professor R. C. 
Kedzie of the Michigan Agricultural College, and Professor M. A. 
Scovell of the Kentucky Agricultural Experiment Station. The 
results of these analyses are published in Bulletin 96 of the Michigan: 
Station, and from them Professor Cook draws these conclusions: 
1. That chemists can easily detect adulteration of honey by use of 
glucose, in all cases where it is likely to be practiced. The same would: 
be true if cane sugar syrup were mixed with the honey. 
2. That a probable method to distinguish honey dew honey from 
honey adulterated with glucose has been determined by these analyses. 
The right-handed or slight left-handed rotation together with the large 
. amount of ash, and small amount of invert sugar indicate honey dew 
honey. As honey dew honey will never be put onto the market, this 
pone is of scientific rather than practical importance.
