THE CANADIAN ENTOMOLOGIST. 193 



generically distinct, even from each other and his latest (Ashmead, 1904), 

 diagnosis of Trichogramnia was wrong, and would lead to the belief that 

 japonicum was entirely different structurally from what it really is ; more- 

 over, as I will show, it is variable in colouration, again misleading me, 

 since the original specimens were black, those first in my possession 

 yellowish-brown. 



The identity of this species was not suspected until some months 

 after I had drawn up the description of JVeotrichogramma from the speci- 

 mens which had been named in MS. acuiivent?'e. In January, 191 1, Dr. 

 L. O. Howard very kindly sent to me for identification a second lot of the 

 same kind of egg-parasites, consisting of six balsam slides labelled 

 "Formosa, Japan, T. Shiraki." (Bearing sub-labels "No. 35," "No. 12" 

 and "No. 13," respectively, bearing two males, one male plus two females, 

 one male plus two females, two females, two females and one male in the 

 order of their naming). The host was not given. All of these specimens 

 were nearly black, with the exception of a single male of the "No. 13" ; 

 some were suffused with brownish. These specimens could not be 

 separated from the others first seen by me, a part of which had been 

 designated as the co-types oi aciitiveiitre MS., and they were consequently 

 identified as that manuscript species, with a statement to the effect that 

 perhaps the latter would prove to be identical with japonicum. Suspect- 

 ing this to be true, after knowing of the colour variation and again con- 

 sulting the literature, I addressed Mr. J. C. Crawford, of the U. S. 

 National Museum, in regard to the types of japonicum heretofore not 

 found, and he responded by sending me one male and four female speci- 

 mens on tags, and which had been compared with the types (hence homo- 

 types) ; these could not be separated from the specimes previously 

 mentioned. They bore the label, "Ex eggs Chilo simplex, T. Fukai, 

 Konosu, Saitama," and were coloured like the second lot above, varying 

 from brownish to black, and were from the same host as the specimens 

 first seen by me. Subsequently Mr. Crawford generously sent one of the 

 type specimens (a female), and it in turn, as was to be expected, proved 

 to be identical with the other. Hence there can be no doubt that the 

 specimens mentioned in foregoing, more especially those upon which 

 JSFeotrichogratnma was founded, are 3\\ japonicum Ashmead. 



( Trichogramma) Neotric/iogramfna japonicum Ashmead is parasitic 

 on the eggs of the lepidopteron Chilo simplex ; the specimens upon which 

 Ashmead founded the species were stated to have been reared from
