Mr. Scudder communicated: to us some years ago an interesting 
fact in reference to this spe- eae 
cies. It appears that the 
caterpillar, in 1840, ravaged 
the Aristolochias in the Bo- 
tanic Garden at Cambridge? 
and had never afterwards ¢ 
been seen in that vicinity 
until some plants of Aris- 
tolochia were taken from 
the Botanic Garden to Bev- 
erly, a few miles distant, 
when caterpillars appeared 
in 1876, on.the Beverl

“I send you herein enclosed a butterfly, and though it is by no 
means a rare one, yet from the multitudinous swarms of it now 
flying about and literally fi//ing the peach trees now in full bloom, I 
wish to know something more about it. I never saw so many 
butterflies of any one kind as there now are of this. The little 
yellow fellows that are seen in the summer around ‘mud puddles 
in the road, are few in comparison.’—C, V. Riley. 
ANATOMY OF THE MitKweED Burrerrty.—Mr. Edward Bur- 
gess has lately published a paper on the structure of Danais 
archippus, which describes the anatomy of that butterfly with rare 
accuracy and clearness. Students of insect anatomy will espe- 
cially appreciate this memoir, contained in the anniversary vol- 
ume of the Boston Society of Natural History. It is one of the 
best €ntomological articles yet published, and makes us look for- 
. ward eagerly to the appearance of other monographs upon other 
Species of insects, which Mr. Burgess is understood to be en- 
ooks 
described or entirely overlooked by earlier writers. To him Bele
