In conclusion, the author states that these groups will probably be reduced 
to 9, namely. Nos. 1, 3+2, 4, 6, 7+6, 9+8, 10, 12+11, and 16=13-17. 
Morawitz also remarks upon the following species of the genus Crahro 
(1. c. pp. 266-272) : — Rhopalum nigrintcm (Kiesenw.) is an intermediate form 
between Physoscelis and Corynopus^ and its $ is probably described by 
Wosmael as Rhopalum gracile. Both names are previously employed in 
Crahro) and Morawitz proposes to name the species C. kiesenwetteriQ. c.p. 267). 
The species of the Blepharipus group seem to vary much as regards the 
sculpture of the metanotum ; C. congener (Dahlb.) is a variety of C. poda- 
^nct/5(Vanderl.). The mesopleural denticle is variable in species of Crosso- 
cents ; C. ovalis (St. Farg.), amhiguus (Dahlb.), and nigrita are particularly 
mentioned by Morawitz. Morawitz also give^a table of the species cited by 
Eversmann in his ^ Fauna Volgo-Uralensis,’ with their localities, and remarks 
on their synonymy (/. c. pp. 269-272). 
Crahro guttatus (Vanderl.). The cocoon of this species is described by 
F. Low, Verb, zool.-bot. Ges. in Wien, xvi. p. 961. 
Crahro. Of this genus, as defined by him (see p. 422), Morawitz describes 
the following new species: — C. {Rntomognathus) sahlhergi, 1. c. p. 267, 
Ochotsk ; C. {Chalcolamprus') luteiventris, ibid., of unknown origin ; C. {Ble^ 
pharipus^ hirtipeSj c. p. 258, Spask ; C. {Crossocerus) pullulus, 1. c. p. 269,
