GENERA AND SUBGENERA OF BEES—SANDHOUSE 539 
Cladocerapis COCKERELL. 
Ent. News, vol. 15, p. 292, 1904. 
Type.—Lamprocolletes cladocerus F. Smiru, 1862. (Monobasie and original 
designation. ) 
Ciaremontiella CocKERELL. 
Pan-Pacific Ent., vol. 9, p. 25, 1933. 
Type.—Spinoliella euxantha CocKERELL, 1916. (Monobasie and original des-

Type.— (Hylaeus albilabris Faprictus, 1793)=Apis cucurbitina Rosst, 1792. 
(Monobasic. ) 
Although Dalla Torre, Catalogus hymenopterorum, vol. 10, p. 195, 1896, cites 
Clavicera as a synonym of Ceratina Latreille, the former name has priority. 
Richards, The generic names of British insecis, pt. 5, p. 91, 1937, has pro- 
posed that the name Clavicera Latreille be set aside and have no status in 
nomenclature and that Ceratina be retained. 
Clisodon Parron. 
Bull. U. 8. Geol. Surv. Terr., vol. 5, p. 479, 1879. Two species. 
Type.—Anthophora terminalis Cresson, 1869. (Original designation. }

TIsogenotypic with Huglossa Latreille through synonymy. 
Cnemidium Perty is preoccupied, but since it is a synonym of Huglossa 
Latreille, no new name is proposed to replace it.

species.
