and the posterior border obtusely rounded or subtruncate. The 

 second and third pairs of legs are nearly equal and considerably larger 

 than the anterior pair, and their tarsal claws are broad and blunt or 

 obtuse at tip. The abdomen is elongate, segments one to seven with 

 prominent chitinous processes at margin ; long stiff hairs are scattered 

 rather sparsely over the disk and along the margins. Length of $ 1.20 

 mm., ^ .75-. 80 mm. 



This species approaches inonianus, Osb., in form, but is narrower 

 and smaller. It differs also in the form of the sternal plate. 



Described from a number of specimens taken from the Columbian 

 Spermophile, Spermophiltis colujfibianus, at Pullman, Washington, by 

 Prof. C. V. Piper, in July, 1896. Type material in the U. S. National

 The author divides the diurnals into two series or superfamilies, 

 Papilionides and Hesperiades, and twelve families, giving diagnoses of the 

 divisions. The classification is phyletic, and takes into consideration the 

 facts of the scanty record from fossil material. As a result of these studies 

 six larger associations of butterfly forms of general distribution are recog- 

 nized, and as many smaller groups, inhabiting a restricted territory, and 

 giving evidence in most cases or being survivals of once more extensive 

 complexes. The nomenclature has been reviewed, and the author hopes 

 the work may conduce to conformity in the treatment of the butterflies in 

 literature.
