aa. Maxillary palpi not present in either sex ; spines of the cephalic row 

 on abdominal segments 7-9 not on distinct ridges, the spines never 

 extending laterad beyond the spiracles ; setae on the ventral side of 

 cremaster heavily chitinized, and usually not extending far beyond 

 the caudal margin of the body Peronea Curtis.

Family Sparganothidae 



This family (Fig. 44) includes the species in which the cremaster 

 is well developed and much longer than broad, except in Archips (b) 

 and Phaecasiophora. The cremaster in nearly all species bears eight 

 strong hooked setae which are usually not much flattened except in 

 the genera mentioned above. There are never any setae present on 

 the anal rise, and most of the species have no spines present on the 

 ninth abdominal segment and none of them a well-developed row. The 

 caudal row of the eighth segment is often lacking in the female and 

 is poorly developed in the male. The females of Platynota flavedana 

 have no cephalic row on the second abdominal segment. The members 

 of this group include the largest of the Tortricoidea examined, most 

 of them considerably over 10 mm. in length; the thoracic region 

 usually appears considerably enlarged, and the abdomen is long and 

 tapering. The vertex is shorter than in the other groups. The max- 

 illary palpi do not reach the proximo-lateral angles of the maxillae in 

 the males, but sometimes do so in the females. In Platynota flavedana 

 the palpi appear to extend only along the cephalic margin of the pro- 

 thoracic leg. The setae of the body are usually very long and promi- 

 nent in this group. Sexual differences are noticed in the length of 

 the maxillary palpi and antennae and in the development of the rows 

 of spines on the dorsum of the abdominal segments. There are no 

 available characters by which all the species of the genus Archips can 

 be associated in a single group and it undoubtedly represents two 

 genera, because there are two distinct types of cremaster present. It 

 is also difficult to find good structural characters to separate the genera 

 Harmologa and Archips (a). The color markings are very distinct in 

 Harmologa, and the body is also very noticeably enlarged in the region 

 of the first three abdominal segments, so that in ventral view the lateral 

 margins of the wings appear curved, instead of approximately parallel 

 as in Archips (a). The genera Epagoge and Platynota are also closely 

 related and are grouped together by some writers. The genera of 

 Sparganothidae may be separated as follows :
