four females, all now on a slide in xylol-balsam and in tolerably good 

 condition. They are returned to Mr. Schreiner as requested By the 

 sender. The species appears to be the only one of the genus with a dis- 

 tint color pattern. 



5. Trichogramma fasciatum (Perkins) and Encyrtus embry- 

 ophagus H a rtig. 



''Mr. Kurdjumov again sends me a number of females of this 

 species bearing the label „Egg-parasite of Codling Moth. Tashkent, 

 Turkestan, R. T. 25. VIII. 12. Collector A. F. Radetzky«. He remarked 

 in his letter: "The second vial contains the egg-parasites of the Codling 

 Moth imported into Turkestan from the European Russia. I believe it is 

 identical with that species I sent to you formerly. It seems to me it 

 should be considered as Pent. {Encyrtus) embryophagiis Hartig. I have 

 seen H a r t i g's type among the collections of the Museum für Naturkunde 

 in Berlin, Germany. There were only females and all of them of very 

 bright yellow color, just the same as the species I sent to you. In a note 

 in Revue Russe d'Entomologie, I pointed out that P. embryophagus 

 Hartig must be identical with P. semblidis A u r. Now, I will take 

 back this opinion. I supposed P. semblidis was very variable in color. 

 Yet, as a matter of fact I have never been able to find here yellow 

 semblidis". 



H a r t i g's Encyrtus embryophagus is unknown to me, so that I am 

 unable to pass an opinion upon Mr. Kurdjumov' remarks. Coloration, 

 as I have remarked before, is usually an unreliable specific character 

 in Trichogramma. From what Mr. Kurdjumov states, however, we 

 must include Hartig's species within the Trichogrammatidae and not 

 in the Encyrtidae. 



Trichogramma fasciatum is now known to be parasitic upon 

 Diatraea saccharalis and Carpocapsa pomonella and occurs in Russia, 

 Mexico and Turkestan. More than this, it is probably synonymic with 

 Trichogramma {Encyrtus) embryophagus (H a r t i g). 



6. Trichogramma semblidis (A u r i v il 1 i u s). 



With the above specimens, Mr. Kurdjumov also sent nine 

 females of a species of Trichogramma labelled „From eggs of Mamestra 

 brassicae. Kiev, Russia V. P. Pospjelov", remarking in his letter that 

 the species is semblidis or the one known there under that name. Upon 

 examination, I think the species is semblidis, but I could be more 

 certain if I knew of wingless males occurring with the species, the only 

 certain way of distinguishing semblidis from minutum. 



A fourth vial from the same sender contained six females of the 

 same species, the specimens labelled „From eggs of Agrotis segetum 

 Schiff. Aug. 1912, Kiev, Russia. V. Pospjelov." The identification 

 is made with the same qualification as in the preceding case.
