THE ENTOMOLOGIST Vol. XXXVIII.] SEPTEMBER, 1905. [No. 508. NEW AUSTRALIAN BEES OP THE GENUS NOMIA. By T. D. A. Cockerell. Ten species of Nomia have been recorded from Australia, all described by F. Smith, and published in Trans. Ent. Soc. Lond., one in 1862, and nine in 1875. Smith remarked that N. generosa was probably the male of N. mcerens, and I believe that N. rufi-comis (smithella, Gribodo, 1894) is the male of N. nana ; so the list probably includes only eight valid species. It is evident, however, that it does not do justice to the actual facts, for the British Museum collection contains quite a series of hitherto unreported forms, which I describe below. The Austro-Malay islands (including Celebes, the Moluccas, New Britain, the Aru islands, &c.) are rich in species of Nomia (twenty-one described), but, so far as I am able to ascertain, none of these are quite identical with those of Australia, nor is any species very widely spread among the islands. The following table separates the species now described : — Hind margins of abdominal segments pearly green ; hind femora incrassate and humped above ( $ ) pulchribalteata subsp. austrovagans, Ckll. Hind margins of abdominal segments not so . . 1. 1. Tegula3 very large, light fulvous; sides of face covered with white tomentum ( $ ) . . . . . lepidota, Ckll. Tegula? not especially remarkable .... 2. 2. Tibire and tarsi red, the former with a suffused blackish mark in front ; face covered with fulvous tomentum ; abdomen with rufo-fulvous hair-bands ; hind legs hardly deformed (cf ) . . • • rufocognit a, Ckll. Tibiae and tarsi not red, or not distinctly so . . . 3. 3. Black species ; abdomen without well-developed hair-bands ($) tenuihirta, Ckll. Abdomen distinctly banded with hair, or the segments whitish margined . . . . . . . 4. ENTOM. — SEPTEMBER, 1905. T
