Tijpe.—^o. 580, U.S.N.M. 



One single example, a male, was taken on Glorioso Island. It agrees 

 in color and many other characters with L. tyansvcrsicoUis, Fairmaire, 

 described from Sainte-Marie-de Madagascar, JMalie, and Mayotte, but 

 Doctor Fairmaire's species has the third ventral segment pale and the 

 posterior angles of thorax nearly rectangular. The genus is of wide 

 distribution in the Old and Xew World. 



2. PERISSOSOMA ^ENESCENS, Waterhouse. 



rerissosoma anescens, Watekiiouse, Anu. Nat. Hist., 4 ser., XV, 187.5, p. 415. 



Four examples of this very peculiar Melolonthid, of doubtful sj^stem- 

 atic position, were collected by Doctor Abbott on Glorioso Island. 

 They agree exactly with Doctor Waterhouse's description, the type of 

 which was from the Seychelles.
