ON SOME JAPYGIDyE IN THE MUSEUM OF 
COMPARATIVE ZOOLOGY (DICELLURA) 1

During my last visit to Harvard University, at the 
Tercentenary Celebration (1936), I received a small col- 
lection of Japygidse from the Museum of Comparative 
Zoology. Study of this material shows that the col- 
lection includes : 
1) Specimens of J. subterraneus Packard, which I 
think worthy of redescription in order to fix the 
characters of this species, the first japygid de- 
scribed from the United States. 
2) Metajapyx confectus sp. n. from Washington, Dis- 
trict of Columbia. 
3) Evalljapyx sonoramis Silv., which is redescribed 
after comparison with the type from Arizona. 
4) Evalljapyx dispar sp. n., from Santa Cruz Island, 
California. 
5) Evalljapyx darlingtoni sp. n., from Jamaica. 
6) Japygianus wheeleri gen. n. et sp. n., from Queens- 
land, Australia.
