into joining them as somewhat aberrant members of the same subfamily. 

 Taking the ii-veined American species, ahiiost every pecuHarity pos- 

 sessed by them is found among the PhvcitiJ^e, and even in the antenna! 

 process there is an insensible inteigradation into what is found in the 

 Pkycilido'. 



It is highly probable that too much importance has been given to 

 the possession by these insects of this peculiar aniennal process. One 

 ought to be cautious in giving even generic weight to a secondary sexual 

 character, but when there is a gradation from a strong development into 

 the entire lack of the character, relationships should be sought for on 

 other grounds, and if possible in those which like the antennal process are 

 more or less peculiar, viz : the pencil-tufted maxillary palpi, the bitufted 

 antennae, the erect recurved palpi, ihe cross ridges of scales on wings, 

 the costal fold beneath the fore wings, and the genital armature. Taking 

 all these characteristics we feel certain our American species are very 

 nearly related to the Phycitidce and that they connect these with the 

 Pyralidin.e though much closer to the former than the latter. 



The points of affinity to the /'//rc'/Z/i'A? are nut a few and even in 

 their widest differences the two groups are strongly correllated. 



In the palpi, antenna;, clypeus, ocelli, pencillate maxillary palpi, 

 venation, costal fold, viteous spot, scale ridges and general construction 

 of the genitalia the E/'ipaschinte agree with certain of the Phyci/idie, or, 

 what amounts to quite as much, they do not agree with each other. 



The points of difference are as follows : ist, the bilobed maxillary 

 palpi ; 2nd, the antennal process ; 3rd. the basal tuft on underside of 

 fore wings on inner margin ; 4lh, the frenulum, single in ^, double in 

 9 ; 5th, the hair pectination of the lower median vein of the hind wings. 

 In all these the EpipaschiincB are distinct from the P/iycitida'. 



In most of these very peculiarities of tfie Epipaschiitiae however, 

 there is an approach to the Phyciiidae, or the tendenc}' is found anmng 

 the Phycitidae. The bilobed maxillary palpi we speak of as a tiiflerence 

 though it is by no means such. It is ratlier one of the most convincing 

 proofs of close relationship to the Phycitidae ; for this peculiarity, other- 

 wise so far as we know unique, is possessed by some of the Phycitidae. 

 The bilobing is a modification of the two ultimate members in which 

 the last is set not on the end but on the side of the one beluw, and 

 generally near its base, so that in some instances the two members seem 

 to be almost set together on the summit of the antepenultimate member. 

 Among the Epipaschiinae there is some variation, for in Otieida luuiilalis 

 the end member is above the middle of the one on which it is p i.ucd. 

 Among the Phycitidae in all cases of the hair pencilling of the n axillary 

 palpi examined by us, both the end members are pencilled, and there is
