Hub. — Steilacooin, Puget's Sound, (Dr. Geo. Suckley.) 



This species is smaller than the preceding and darker in color, especially on the upper surface 

 of the head and hody. The hill also is much more slender. The only specimen that we have 

 ever seen is in the coUection^made by Dr. George Suckley, U. S. A., whose name we have taken 

 the liberty of applying to it, as a slight testimonial to his great zeal and ability as a naturalist 

 and scientific traveller. 



According to Dr. Suckley, this species is said by the Indians to be not uncommon on Puget's 

 Sound. He further states that in life the membrane at the base of the upper mandible is 

 grayish dusky, the knob (!) slightly more greyish. The middle of both mandibles dingy 

 orange, their tips dusky. Iris pale hazel. Under surface of toes bluish white, darker about 

 the articulations ; nails black.
