Buteo lagopus (Pontoppidan) — Rough-legged Hawk. 

 Aacipiter gentilis (Linnaeus) — Goshawk. 

 Acaipiter cooperii (Bonaparte) — Cooper's Hawk. 



Price and Beer (1963a) include this species in their os&omi-group 

 with 5 other species none of which are found in New England. Thus the 

 following characteristics will serve for determining C. nanum: 



1. Mid-dorsal head setae long. 



2. Occipital setae all long. 



3. Margin of prothorax with 5 long and 3 short setae on each side. 



4. Abdominal tergites III-IX of 9 usually showing faint division into 

 2 or 3 parts. 



5. Anus of female usually indented dorsally, always with ventral and 

 usually with dorsal inner setae. 



6. Vulva flattened, with prominent lateral row of hooked spines. 



7. Male genitalia without lateral posterior projections on the genital 

 sclerite; penis barbed.

The M. C. Z. material contained specimens with the label 

 Colpocephalun flavesaens . The determination was by Peters and these 

 could be C. nanum Piaget, 1890.
