anterior border, base and a short stripe in the middle reddish- 

 brown ; femora with inner side pale testaceous, remainder reddish ; 

 tibiae and tarsi reddish-piceous ; arolia large. Abdomen ventrally 

 pale yellowish, each segment with a narrow dark basal band extend- 

 ing to lateral margin. Cerci as long as lamina, slender, pale yellow, 

 terminating in a short spine.

diameters. " Body very flat and thin, elongate. Integument 

 soft. Supra-anal lamina of male triangular, terminating in an acute 

 apical spine. Colovir pale with dark bands." 



The only species of this genus which I have seen is 

 L. sccunda, Tepp., and that is undoubtedly conspecific 

 with Cutilia triangidata, Br, (q. v.). The only important 

 character in Tepper's generic diagnosis is the form of the 

 male supra-anal lamina, and as there are many objections 

 to founding new genera on male secondary sexual characters 

 alone, I expect that it will eventually be necessary to sink 

 Leptozostei'ia as a synonym of Flatyzosteria or of Cutilia.

(liaracters. Closely allied to Flatyzosteria, Br., but the posterior 

 metatarsus long and biseriately sj^ined beneath, its pulvillus apical ; 

 remaining tarsal joints unarmed beneath, their pulvilli occupying 

 the entire joints. Tegminal rudiments present. In all but one 

 species the posterior angles of the distal abdominal tergites strongly 

 produced backwards. Supra-anal lamina ( ^ ) quadrate. 



Type of the genus — C. nitida, Br. 



Stal founded the genus on C. tartarea, StS,l, which is 

 synonymous with C. nitida, Br. The genus is a link
