From the general appearance of these appendages, their existe 
on all of the tarsi, and on all of the insects of this species hitherto 
examined by me, I do ote think they result from disease, but are cha- 
racteristic of the insect.”—-T. Chambers, Covington, Ky. 
he wasp is evidently allied to Tachytes, one of the Larride. We 
trust our correspondent will, during the coming season, secure speci- 
mens for accurate identification, and renew his observations on a point 
so interesting alike to the cope a and Botanist 
We sent Mr. Chamber’s drawings to Mr. Horace Mann, of Cam- 
bridge, without reem that the insect had been seen on the Ascle- 
pias, who thus write 
“I received your sii) with the very interesting sketches in it, last 
evening. The masses which have attached themselves to the wasp’s 
leg, are, as you suppose, pollen, that of some species of Asc lepias, the 
Milkweed or Silkweed. By referring to Gray’s Manual of Botany you 
will find the structure of the flowers described on p. 351, and by refer- 
ring to his Systematic and Structural Botany you will see it figured 
on p. 459. I showed the drawings to Dr. Gray, who was very much 
delighted with them, and begs; as I do, that you will have a wood-cut 
made of the small one, to show what a quantity the wasp managed to 
pick up in his perigrinations. A cut reduced to half the size of the 
drawing would atte every purpose, and be very interesting and in- 
structive to Botanis' 
In our specimen a Tea there are four pollen masses attached to 
the spines on two of the legs. They evidently adhered to the spine 
by the viscid base of the pollen mass. They agree well with the draw- 
ing of Mr. Chambers, of which we give a wood-cut reduced one-half. 
In regard to works on the Hymenoptera, or bees, wasps, etc., of this 
country, you will find many species described in H. de Saussure’s 
great work on the Vespidæ (Monographie des Guepes Sociales, Paris 
et Genève, 1853-58, 3 vols., 8vo). You will also find the Catalogue of 
Hymenoptera in the British
