Alydus eurinus Say 

 This black species, with red-banded abdomen is 

 about J,2 inch in lenj^lh, and on account of its slender 

 form and peculiar movements, resembles an ant to 

 some extent. It was observed in small numbers on 

 scrub oak at Karner, one specimen being taken June 

 21, 1901 and another in early July 1902. This insect 

 has a wide distribution, having been recorded from 

 as far west as Colorado, south to Texas, as occurring 

 in the Eastern States and ranging north into Canada. 



Acholla multispinosa 1 )eG. 

 This predaceous, spin)- hemipteron is one of our 

 rather common though rarely abimdant forms. If is 

 about 'j inch long, slender in shajx', and varies in color 

 from light to dark l)rown, ami it ma\ l)e ri-cognized by 

 the prominent s|)ines on the top of the head. The 

 young are similar in appearance to the adults, though 

 usually with the abdominal segments colored more or 

 less deeply with red. 



Adults of this species were taken in 1901 on hard 

 pine at Karner Aug. 9 and 21, and Sep. 6. Immature 

 specimens of what probably belong to this species were also taken earlier
