 serrata pectinated. The front is smooth, thickly, somewhat woolly haired.

 vated scale ridge behind the collar, and a tuft behind, while the abdomea 

 is stout and usually untufted. The eyes are naked, the tibiae unarmed.

PHALANGODES ROBUSTA (Pack.) 



Dear Sir : Packard, in 1877, described this species from specimens 

 taken in Colorado by Mr. E. IngersoU in 1874, but the precise locality and 

 habitat were entirely forgotten. In his recently published memoir on the 

 Cave Fauna of North America (Proc. Nat. Ac. Sci., Vol. IV.), he re- 

 describes the species, which is of extreme interest as being an out-of-door 

 species of a usually cave-inhabiting genus, and suggests that it will prob- 

 ably be found under stones, though its precise manner of life, etc., remain 

 as little known as in 1877. I am therefore pleased to be able to record 

 that I have found a Fhalangodes, agreeing quite well with F. robtista, in 

 very considerable abundance by Swift Creek, Custer Co., Colorado, in 

 damp places in a grove of Populus tremuloides, ahvays under logs, and 

 never, to my knowledge, under stones. This is about 8,200 feet altitude. 

 I met with the same species under logs near Clearwater Creek, on the 

 Grand Mesa, Mesa Co., at about 9,800 feet altitude.

A NEW MYRMOPHILE. 



Dear Sir : On pp. 165-166, Vol. xx., Dr. Hamilton gives a list of 

 eight species pf Cremastochiliis known to be Myrmophilous. I can add 

 one other, namely, C. Knochii Lee, which I found in an ants' nest on 

 March 30th, last year, near Swift Creek, Custer Co., Colorado, at about 

 8,100 feet alt. This was under a stone on the open prairie.
