On December 30th, 1904, I examined for spiders a small cave on the north bank of the Missouri River, three miles below Rochport, Mo. This cave is occupied by a small strea, which enters it by an opening some distance from the river, and leaves it in a narrow gorge cut back in the bluffs.

The bees now described not only appear to differ from any previously published; but they have been kindly examined by Messrs. Viereck and Titus, and found to differ from all of the numerous species which they have named in manuscript, and will shortly publish.

In the three types to be considered in this place, then the conspicuous portion of the perianth is almost always campanualte or more generally widely patent and sometimes reflexed. The anothers are regularly elongate in form, linear or subulate, and basifixed on filaments of greater or lesser length. The pistil is usually simple, with filiform style and punctiform stigma, but to this there are rare exceptions. The Dilleniaceous type is distinguished by its numerous, generally free, stamens with long or short filaments, and sometimes several pistils free almost to the base.

Of the ten superfamilies recognized in my classification of the Hymenoptera, all have been classified down to genera except the Ants, or superfamily IV, Formicoidea, a very large and most difficult complex, and rendered even more difficult by the extraordinary number and diversity of the sexes, there being sometimes several different forms to a single species.

Among the mosquitoes lately sent from the various Army Stations are the following, of interest mostly because of their apparent close relation to already known forms:

Uranotœnia cœruleocephala, Theob., var. lateralis, n. var.— ♀. Head covered with flat blue scales, becoming white around the eyes, a couple of brown bristles between, and a few around, the eyes, no fork scales; the scales on the occiput change from a dark indigo or violet to a light blue, according to the direction of the light, and when viewed from the side may even seem brown with a wide white border around the eyes, but in other positions are some shade of blue; antenn♀ brown, verticels and pubescence brown, basal joint light testaceous, with a few thin flat scales; palpi also light brown, very short, hardly longer than the depth of the clypeus, the last joint reduced to a knob; proboscis dark brown, swollen at the tip; clypeus testaceous; eyes brown and silver.

When I saw Professor Vernon L. Kellogg's new “American Insects” advertised, I determined to posses a copy, which I thought would very naturally give a little more space than “Comstock's Manual” to the Heteroptera, and being a much more recent publication, would be free, with regard to the Waterbugs, from the mistatements and errors of fact of its predecessors and therefore serviceable as a book of reference. Very fortunately (from my point of view), a friendly bookseller allowed me to examine the volume and in consequence I was able to spare myself a useless expense.

In the case of any circumpolar plant, it is of much interest to learn whether the insects and fungi attacking it are the same in Europe, Asia and America. The Bearberry (Arctostaphylos uvaursi) is already know to have a cocci (Targionia Dearnessi, Ckll.) infesting it, which is only known to occur in America. This T. Dearnessi, however, is not confined to the Arctostaphylos, for Professor L. Bruner sent me specimens which he collected Oct. 24, 1900, at Weeping Water, Nebraska, on Ceanothus Americanus.
