constantly endeavored to render it of practical service to the 

 people of his state. For several years, during the chinch bug 

 invasion of Kansas, he labored heroically to aid the farmers 

 in their extremity. However much question there may be 

 regarding the practical effects of his labors there can be none 

 concerning his devotion and singleness of purpose toward the 

 cause of those into whose service he thus entered. Many are 

 firm in their belief of personal indebtedness to Doctor Snow 

 for his assistance in their time of trouble. 



Much more might be said of this excellent man, but it would 

 all be of the same kind and tenor. He was one of Nature's 

 noblemen earnest, sincere and devoted ; full of optimism, 

 good cheer and courage. He lived a life of simple earnestness 

 and hundreds of devoted students have felt and acknowledged 

 its influence for good. The University of Kansas honored 

 itself by formal memorial services devoted to his memory on 

 Xovember 10, at which time his old friends and students spoke 

 most appreciatively of his services to science and to the state.

Two new species of the genus Phthiracarus. 



BY H. E. EWING, Urbana, 111. 



The genus Phthiracarus is one of the two genera which 

 compose the subfamily Hoploderminae, of the family Ori- 

 batidae. The members of the subfamily Hoploderminae are 

 remarkable in that the cephalothorax is hinged to the abdomen 

 and is capable of being folded down upon the ventral surface 

 of the latter in such a way as to completely cover and conceal 

 the legs and mouth parts. This arrangement enables these 

 small Acarina to successfully protect themselves from many 

 of their small predaceous enemies. Up to the present time 

 only four species of the genus Phthiracarus have been recorded 

 from North America, the two described in this article making 

 six known to this country. The writer is indebted to Mr. 

 H. Glasgow for the collecting of one of the species.
