THYSANURA. 



Campodea Americana n. sp. 



This species is closely allied to the European C. succinea Mcolet, 

 but seems to differ in the body being very transparent, and of the 

 same color as the appendages ; like that species the anal appendages 

 are 14-jointed. It is throughout of an amber yellow color. The an- 

 tennae have the basal joint short and about one-fifth broader than the 

 succeeding ones, and is short, about one-half as long as broad, being 

 obliquely truncated, the outer side being the longer. The anal ap- 

 pendages are long and hairy, the joints gradually increasing in length 

 until the terminal one is lanceolate oval, and nearly as long as the 

 10th abdominal segment is broad; between their bases is the broad 

 triangular 11th tergite. The hairy, single-jointed tarsus is as long 

 as the tibia, and ends in two rather long curved claws. The protho- 

 rax is considerably narrower than the head; it is about one-half 

 as long as broad, sublunate, much rounded behind; the mesothorax is 

 as round as the head, well rounded in front, and very free from the 

 pro thorax, under which it moves ; the hinder edge is square, slightly 

 rounded; metathorax square in front, a little rounded behind", espe- 

 cially on the sides. 



Abdominal segments very equal in length, with the sides a little 

 produced posteriorly, terminating in a bristle. The abdominal lateral 

 locomotive spines are slender, acute, 2-jointed, the basal joint a little 

 longer than broad ; the second joint moving like a finger backwards 

 and forwards, acting both as abdominal supports and as locomotive 

 organs. The head and body are covered with fine yellowish hairs. 



Length .12 of an inch. 



I found these specimens in Salem, under a stone in damp soil early 

 in April. This is the first occurrence of any of this family (Cam- 

 podece of Meinert) in the United States. A species of Japyx (J. 

 Saussurii Humbert, Rev. et Mag. Zoologie 1868, p. 345,) was dis- 

 covered in Mexico by Prof. Sumichrast, and it should be looked for 

 in Texas and the neighboring states. 



MYRIAPODA. (PAUJROPODA.) 



Pauropus Lubbockii n. sp.
