In Camptodhiin. ]\Ir. Lewis has been fortunate enough to 

 recover oue of Col. Motschulsky's lost genera. Tlie insect taken 

 by Mr. Lewis agrees entirely with the cliaracters given in his 

 very short and unsatisfactory description, and also with his 

 figure (Bull, Mosc. vol. xli, tab. 8, fig. 4). 



It is a curious and interesting species, in form much re- 

 .senibling the >Scijdvi(vni(la\ l)ut in all its anatomy a true 

 Triclioptcrijgian.
