The following paper is based ui)on the matei'ial of this family 

 embraced in the entomological collection in the Museum of the 

 Indiana University. 



In connection with the descrii)tion 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. JIJI.ID.3E Leach. 



Genus f. JULUS Linn. 



JuLus Liiinanis, Syst. Nat., Ed. X, I, 639, 1758. 



This genus differs from Parajulus in the mandibulary combs 

 being four ; the first segment of an equal size 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 uncinate. 



As the subgenera of this genus are very much confused, I have 

 not attempted to give a key to those to which the following spe- 

 cies belong, 



1. JUI.US OAVENII, sp. nov. 



Pale brown, a lateral series of dark brown spots, tii'st dorsal plate with 

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

 ej'es ; a pale oval spot at the base of antennae ; feet and antenna pale. 

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

 median sulcus ; setigerous foveolje absent. Antennae siibclavate, 

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

 jdwa3^s filled out, about 28, arranged in 6 or 7 series. Sci^-ments 3S-
