descriptions, which are fairly accurate as far as they go, the arrange- 

 meut would have been still more annoying. 



It had been my fear for some time that probably there were 

 a number of errors in the Abbe's classification of species which 

 he described as new. The synonyms which Mr. Cresson found in 

 making his check list, the reports of other careful workers who had 

 seen some of the Abbe's work, and some examples of his determina- 

 tions sent me for verification, all went to prove this suspicion was 

 not without foundation. Feeling that good scientific work could not 

 be continued on the IchneumouidiTe as long as many uncertain species 

 were of doubtful classification, it seemed wisest to rectify these errors 

 before any further descriptive work was done in the family. This 

 and a chance to study the types was the object of my visit. To say 

 that I found errors is needless, as the list following this inti'oduction 

 Avill speak for itself. This list of corrections which I shall give is 

 complete only in one respect, viz. : classification of species in the 

 right genus. There are certainly many synonyms yet to be worked 

 out, but it will take more time to determine these, and the few given 

 herein are what I incidentally happened to recognize at a glance. 

 Quite a number of corrections and additions to the descriptions will 

 also be needed to make them clear and replete, but I shall not at 

 this time even touch upon this matter. The list is from notes taken 

 at the time the specimens were examined. The species not mentioned 

 are correct as to classification. 



Ichneumon adjunctus is the 9 oi Ichn. similaris. 



They are both identical in sculpture, form, and color markings, 

 except face and posterior tibioe and tarsi, which differ slightly in 

 shade. They belong to the genus Amblyteles.
