A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI 131 



Figure 52. — Clypeus (A) and last visible abdominal sternite of male (B) 

 and of female (C) of Chrysobothris adelpha. 



Type locality. — Western States (no definite locality given) ; type 

 female, No. 2692, in Museum of Comparative Zoology, simply la- 

 beled with a lemon-yellow disk, which signifies Western States. Le- 

 Conte described the species from the Middle and Western States. 



Distribution. — From the material examined the distribution of 

 this species seems to be restricted to the region covered by the genus 

 Hicoria. Material has been examined from various localities in 

 the following States: Arkansas. Florida. Georgia, Illinois, Indiana, 

 loAva, Kansas, Louisiana, Maryland, Massachusetts, Michigan, Mis- 

 sissippi, Missouri, New Jersey, New York, North Carolina, Ohio, 

 Pennsylvania, Rhode Island, Texas, Virginia, and West Virginia. 



Hosts. — Adults have been examined that were reared by different 

 entomologists from hickory (Hicoria sp.) and pecan (Hicoria pecam, 

 (Marshall) Britton). The adults are reported in Georgia as feeding 

 at the bases of pecan twigs sufficiently to weaken the twigs, which 

 were later broken off by the wind. 



This species was first described by LeConte (1859) under the 

 name soror, but since this name was preoccupied by soror Castelnau 

 and Gory, 1837, for a species from Cayenne, Gemminger and Harold 

 (1869) renamed soror LeConte, calling it adelpha. About the same 

 variation is found in this species as that given for femorata.

In the typical form of rugosiceps the antenna is not distinctly narrowed to 

 the apex, but has the segments more or less yellowish at the outer margins, 

 and the last segment transverse or quadrate and as wide as the tenth segment,
