Elachertus SpiNOLA=(Elachestus NEES=Elachistus Fobsteb, emendations). 

 Ann. Mus. Hist. Nat., I'aris. vol. 17, 1811, p. 151. Six species. 

 Type. — (Diplolepis) Elachertus lateralis Spinola. (Present designation.) 

 Elachertus abdominalis Spinola, designated by Ashmead, 1904 (p. 354), 

 not a valid name when included. 

 This genus is descrihed in a generic key and six species listed as examples. 

 Of the six species listed one (Diplolepis) Elachertus lateralis (Spinola) 

 had been previously described. The other five species, including abdomi- 

 nalis, are without description except as to the generic characters, which 

 presumably apply alike to all. Under the Code, Opinion 43, the descrip- 

 tion of a genus with the mere mention of a specific name validates not 

 only the generic but the specific name. We do not believe, liowever, that 

 the same identical description can be considered to validate six specific 

 names at one time, and accordingly we have disregarded Ashmead's 

 designation of abdominalis as type and fixed upon lateralis instead.
