REVISION OF MOTHS OF CARPOSINIDAE 57 



shown Bondia JideMs to be a relatively common, widespread species 

 in the western United States. 



More variation has been noted in the genitalic structure of this 

 species than in any other New World carposinid. The genitalic 

 structure of the female is rather uniform; however, considerable 

 variation can be observed in the relative development of the vin- 

 culum-saccus in the male. Rather than attempt a detailed description 

 of this variability, both extremes have been illustrated in figures 

 67 and 68. The observed variation was first suspected as being a 

 possible indication of geographical subspeciation, especially since 

 the Black Hills' population probably now exists completely isolated 

 from the main southern extension of the species; however, subspecific 

 names do not seem justified on the basis of these differences because 

 both extreme types can be observed in either the Arizona or Black 

 Hills material. 



Of the species of Bondia now known, this species api)ears most 

 related to B. fuscata. These two insects share in common two features 

 that apparently are atypical for the genus, as exemplified by B. 

 nigella. In contrast to the tyi)e-species of the genus and several other 

 members, the labial palpi of B. Jidelis and B. Ju.scata show no signs 

 of sexual dimorphism, and veins 3 and 4 are stalked in the hind wings 

 instead of being sei)arate. An unnamed Bondia (s])ecies no. 2) discussed 

 on page 05 may also share these eccentricities. The female genitalia 

 of the latter species further resemble B. Jidelis closely in the structure 

 of the lamella postvaginalis. ]n each species the lateral elements 

 of this structure are thickened, and there exists a lobelike median 

 portion. In general, the lamella postvaginalis is more developed in 

 all three of the species mentioned above than it is in most other 

 species of Bondia, particularly B. nigella.
