HYMENOPTERA.

O. carnksccns (Linn.) = ^ a^nca (Linn.) ; O. Icucomelana (Kirby) = intermpta 
(Scbenck), ('■ p. 352. 
According to Morawitz (1. c.), O. cenea (Linn.) c? = ccerulescens (Linn.) 
5 = notata (Fab.) = melanippa (Spin.), and O. leucomelana (Kirby) = inter- 
rupta (Schenck), p. 40. Morawitz also corrects Schenck, who has mistaken 
0. leucomelana (Kirby) for parvida (Diif.) and vice versa, p. 41. 
Megachile. Gerstacker (I, c. p. 353), in his remarks on tins genus, separates 
from it M. olhocristata (Smith) = lefebvrei (St. Farg.), M. serrata (Smith), 
M. manicata (Giraud), which he regards as belonging to Chalicodoma , 1. c. 
p. 354. 31. rufitarsis (Giraud) belongs also to Clialicodoma, and must be re- 
named, as there exists already C. rujitarsis (St. Farg.), 1. c. p. 355. M. 
dohrnii (Radoszk.) = monoceros (Eversm.), is a Lithurgus, and probably = 
L. cornutus (Latr.), ibid. M. hucepliala (Forst.) and vestita (Giraud) must 
change their names to avoid collision with two species of Smith, which have 
the priority, ibid. 
Megachile apicalis (Spin) = M. mixta (Costa), according to Gerstacker, 
1. c. p. 360. 
According to Morawitz (/. c. p. 37), 31. tvillouglibiella (Kirby) = fidviventris 
(Zett.), and M. analis (Nyl.) = apicalis (Nyl.) = alhicilla (Eversm.), p. 38. 
Clialicodoma. Gerstacker (/. c.) defines the real limits of this genus, or 
subgenus, and enumerates the European species known to him, with rectified 
nomenclature, namel}’’ : — C. muraria (Fab.), /. c. p. 364; C. bcctica (Gerst.), 
ibid. ; C. lefebvrei (St. Farg.) = 3Iegachile alhocristata (Smith), 1. c. p. 365; 
C. pyrrhopeza (Gerst.) = Anthaphora meliturga (lllig.) = Megachile rujitarsis 
(Giraud), 1. c. p. 366 ; C. manicata (Giraud), 1. c. p. 367 ; C. sicula (Rossi), 
ibid. Most of these species are here also described by Gerstacker. 
Antliidmm. According to Morawitz (/. c. p. 35), A. mamcaium (Linn.) = 
Ajns macidata (Fab.) 5 5 scptcmspinosum (St. Farg.) = nigripcs (Eversm.) 
= nigriceps (Smith) ; A. punctatum (Latr.) = m(wMS (Nyl.) = scm7e (Eversm.), 
var., 1. c. p. 36 ; and A. strigatum (Panz.) = contractum (Latr.) = minus- 
culum (N5d.), 1. c. p. 37. 
Trachusa. According to Morawitz (ibid.), T. sei'ratulee (Panz.) ^ — 
Anthophora byssina (Fab.) $ . 
Chelostoma. According to Morawitz (ibid.), C. Jtorisomnis (Linn.) A = 
maxillosa (Linn.) 5 . 
Heriades. According to Morawitz (/. c. p. 42), II. campanularum (Kirby) 
= Apis Jloi'isomnis minima (Christ.), and II nigricornis (Nyl.) = Chelostoma 
inerme (Eversm.) = H. rapunctdi (St. Farg.). 
Ceratina. Gerstacker (1. c. pp. 173-184) gives diagnoses of, and copious 
critical remarks upon, the following known species of this genus: — C. cucur- 
bitina (Rossi) = Ilylceus albilabris (Fab.) = C. decolorans (Brulle), /. c. 
p. 174 ; C. egrcgia (Gerst.) = <cnea (Brulle) = chalcites (Germar), 1. c. p. 176 ; 
C. cenea (Fab.) = P viridis, var. (Smith), 1. c. p. 177 ; C. smaragdula (Fab.^ 
— maculata (Smith), ibid. ; C. dcntiventris {Curst.) — Megilla chalcites (lllig.;, 
1. c. p. 178; C. cyanea (Kirby) = ? callosa (St. Farg.), 1. c. p. 180 ; C. callosa 
(Fab.) — mauritanica (St. Farg.), 1. c. p. 182. 
Eucera. According to Morawitz {1. c. p. 36), E. longiconiis (Linn.) J = 
Apis tuberculata (Fab.) ^ • 
Ilabropoda (Smith). Dours (Mon. Icon. Anthoph. p. 20) recharacterizes 
this genus, which, contrary to Sichel’s opinion, he thinks should remain
