nidcs, in the shape of a revision of the species catalogued and 
described by Eversmann in 1852 as occurring between the Volga 
and the Ural. Eversmann^s new species are described in detail 
from the types, and the synonymy of some of these, and of species 
erroneously determined by Eversmann, is indicated. The fol- 
lowing may serve as an analysis of the general results: — 
Andrena fiiscosa (Eversm.) ■^xoh^Ay—holomelana (St. F.), A. ovina—pra- 
temis {^y\.)^lcmothorax (Il.-Sch.) ; A. rfwynana—hicolor (Fab.) ; \A. compia 
(Eversm.) collides with A. comptd (St. F.) ;] A. cunicnlaria belongs to Col-

slrangulata=:Y(iv, zonalis (K.) ; A. rosce—schrankella (N}d., Sch. nec Kirby) 
for which Morawitz proposes the name of A. schencld (1. c. p. 18) ; llylceus 
quadricinctus—quadristrigatus (Lat.) ; II. arhustorum=scxcinctus (Fab.) = 
quadricinctus (Oliv.), of which scahiosce (Rossi) = (Walck.) is a 
variety; K. tornentosus= quadricinctus (Fab.); H. ruhellus—\?i,r. $ cylin- 
dricus (Fab.) = c/eyaws (St. F.)= probably rujimntris (Gir.) ; II. ahdomi- 
nalis-\-olhiq)es-=.cylindricus (Fab.); II. mucoreus is a distinct species; Col- 
hies hylmformis probably (Sm.); C. Jloralis is distinct, as also 
Panurghius lahiatus ; Rophites hispinosa = Ilalictoidcs dentiventris (Nyl.). Mo- 
rawitz notices the following additional known species from the government 
of Saratov : — Andrena nitida (K.), Halictus zonulus (Sm.), II. parmdus (Fab.) 
~ A. pidchella (Jur.), Camptopoeum frontale (Fab.) = (Spin.) 
= R. fasciatus (Giraiid) and Nomia diver sipes (St. F.). 
Morawitz (Ilorm Soc. Ent. Ross. ii. pp. 61-79) gives a list of 24 species of 
Andrenides found in the vicinity of St. Petersburg, 2 of which are described 
as new. Of the others he gives descriptions of the following: — Andrena 
ruficrus (Nyl.); A. fucata {^m.) \ A. (Zett.)=: uanans (Nyl.) ; A. 
nigriceps (Kirby) (Nyl.); A. similUma ) A. argentata ) 
A. tarsata (Nyl.) ; Halictus sexnotatulus (Nyl), II. rujitarsis (Zett.) ; and II. 
nitidiuscidus (Kirby). 
Bomhus. Smith has published (Entomologist, vol. iii.) a series of articles 
on the British species of this genus. In the first and second he gives a gene- 
ral account of the habits of these insects, their enemies, kc. (/. c. pp. 240- 
243 & 266-258), together with a list of tlie British species of Bomhus and 
Apathus, and an exposition of the species described by Kirby, with their mo- 
dern equivalents, according to Smith’s views (/. c. pp. 258-260). The re- 
maining articles contain a statement of the synonymy of the species, -with 
remarlcs chiefly on their occurrence and natural history. 1. B. muscorum in-
