Tlic following paper is based upon material of this family embraced 

 in the entomological collection in the Museum of the Indiana Uni- 

 versity. 



In connection with the description of the new species, it has also 

 been deemed best to introduce descriptions of those already known to 

 science. 



The types of the new genera and species are deposited in the above 

 museum. 



Family A. JULUXE Leach. 

 Genus I. JULUS Linn. 



Julux Liniueus, Syst. Nat., Ed. \, i, 639, 1758. 



This genus diners from Pfintjuhi* in the mandibnlary combs being 1 

 four; the tirst segment of an equal si/e in both sexes; the second pair 

 of feet not stunted; and the first pair of the male small, three-jointed, 

 the last joint large and nncinate. 



As the subgenera of this genus are very much confused, I have not 

 attempted to give a key to those to which the following species belong. 



1. Julus Oweiiii, sp. uov. 



Pale brown, a lateral series of dark brown spots, first dorsal plate 

 with a brown band along the anterior border; a brown band between 

 the eyes; a pale oval spot at the base of antenna?; feet and antenna- 

 pale. Moderately slender, not smooth, not pilose. Vertex rough; a 

 faint median sulcus; setigerons foveohe absent. Antenna 1 subclavate, 

 equal to the width of body. Eyes indistinct, subcircular; ocelli not 

 always- tilled out, about 28, arranged in <! or 7 series. Segments ;>S-40. 

 First segment unusually thin, advanced forward to the eyes; sides 

 striate. Other segments moderately striate both above and below. 

 Last segment rounded: anal valves not inarginate, not pilose; anal 

 scale triangular. Repugnatorial pore moderately large, longitudinally 

 oval, touching the transverse suture, which is excised. Pairs of I'cct 

 54-<>(>, rather stout, equaling the width of body. Mule: niaiidibulary
