TWO NEW OREGON CHILOPODS OF 
THE ORDER GEOPHILIDA

Representatives of the two new centipeds described be- 
low were found in a collection belonging to the Oregon 
State College and submitted to me for study through the

The genus Stenophilus was proposed several years ago 
by the writer for several species of this family occurring 
in western America which, while obviously related closely 
to the European genera Meinertophilus and Latzel’s Stig- 
matogaster (Haplophilus Cook), present some characters 
which would require substantial emendation of those genera 
to permit inclusion of the American forms. I am, therefore, 
retaining for our species the name Stenophilus, emended 
now from the original definition in the light of new species 
subsequently discovered. Stenophilus as far as now known 
differs from the European genera mentioned in lacking 
conspicuous sclerotic or chitinous lines on the prosternum 
and in lacking all paratergites. In Stenophilus ventral 
pores may be absent, present on a few anterior sternites, 
or on sternites of approximately the anterior half of the 
body (rothi n. sp.). Sternal pouches such as are present in 
nearly all, if not all, European species of the genera men- 
tioned, have been detected in American forms only in S. 
coloradanus Chamb., in which they occur on segments 25 
to 35. 
American species referred to Stenophilus are now known 
from Colorado, Idaho, Montana, Oregon and California. 
They seem to be replaced farther south by species of Gosi- 
philus which are common in Mexico and the border states 
from California to Louisiana. From these species those of 
Stenophilus are readily distinguished by the deeper, more 
angular, embayment of the labrum with its much stouter
