Z. q Iter ana Kn. is fusca. 



„ //akrna | Burm. I have no doubt thai this is pruniua Lee- 

 from whicii the pruh'nosit)- ot" the surface has been removed by 

 alcohol. By admitting this, some of the following: descriptions 

 may be better understood and the species identified. 

 L. tuicans Knoch, correctly identified, 

 ,, cogiiata Burm, is correctly determined by Leconle. 

 „ gibbosa Burm, The following remark is added to the de.-crip 

 tion ''One of the two specimens before me shows a remarka- 

 ble anomaly ; the ventral segments usually connate are (ree in 

 their middle convex resembling the appearance of barrel-hoops. ' 

 By this seemingly unimportant note I have discovered speci- 

 mens of futilis Lee, which agree as well in the anomaly as hi 

 the description. 

 L. Forsttri Burm. seems to be that described as lugubris Lee, 

 „ Kuothii Gyll. Burmeister described from the type. 

 ,, ilicis \ Burm. I have specimens which seem to agree and will 



require a new name. 

 Z. fimbriata Burm. is the true ilicis Knoch, 



„ crenidaia Frohl, and hiriuida Knoch are correctly determined. 

 „ albma Burm. Known to us but rare, 

 „ rugosa Mels. correctly determined. 

 „ conmia Burm. i-s balia Say, 

 „ quercus Knoch. correctly determined. 

 „ lanceolaia Say, under Tostegoptera, correctly determined, 

 The following are described as Trichestes, 

 Z. insils Fab, correctly determined. 



„ commis Burm. subsequently described as rufiola Lee, determ- 

 ined from a duplicate in Zimmerman's old collection. 

 Z. crinita Burm. subsequently described as glabripennis Lee. 

 „ ephilida Sa}\ correctly determined. 

 „ lungiiarsis Say, correctly determined by Burm. notwithstanding 



LeConte's opinion to the contrary. 

 Z. prununadina Burm, since described as cerasina Lee. 

 f, gracilis Burm. since described as volvula Lee. 

 „ dispar Burm. Subsequently described as Gynnis debilis Lee. 

 The Revision of the Melolonthidce by Dr. LeConte appeared nearly 

 two years after the work of Burmeister. The species of Lachnosterna 

 were described in part as Eugastra, Endrosa and Gynnis, while Toste- 

 goptera was then suppressed. The following are the species ; 

 Z. veniricosa Lee. with cribrosa Lee. as synonym. 

 „ quercus Knoch. correctly determined.
