THE CANADIAN ENTOMOLOGIST. 233 



ADDITIONS TO MY SYNOPSIS OF THE TACHINID^. 



BV D. W. COQUILLETT, WASHINGTON, D. C. 



Since the publication of the above work several additional forms 

 have been examined, the result of which is recorded herewith. Dr. 

 S. H. Scudder kindly presented to the National Museum co-types of his 

 Tachina thedaruin, and of many of the species described in his work on 

 the Butterflies of New England ; in every case these conform to the 

 positions assigned them in my Synopsis. 



Clistomorpha hyalovioides, Townsend, is a synonym of Xysta 

 didyina, Loew. It belongs to the genus Clytiomyia, of which Clisto- 

 morpha is therefore a synonym. 



Cistogasier pallasii, Townsend, Proc. Ent. Soc, Washington, 1891, 

 page 142. This reference was inadvertently omitted in the Synopsis. I 

 have not seen a specimen which agrees with this description.
