Z. quercina Kn. is fusca. 



„ fratenia \ Burm. I have no doubt that this is pruniua Lee- 

 from which the prulinosity of the surface has been removed by 

 alcohol. By admitting this, some of the following descriptions 

 may be better understood and the species identified. 

 Z. micans Knoch, correctly identified. 

 „ cognata Burm, is correctly determined by Leconte. 

 „ gibbosa Burm. '1 he 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 free, in 

 their middle convex resembling the appearance of barrel-hoops. 

 By this seemingly unimportant note I have discovered speci- 

 mens ot futilis Lee. which agree as well in the anomaly as in 

 the description. 

 Z. Forsteri Burm. seems to be that described as lugubris Lee. 

 „ Knochii 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. 



„ crenidata Frohl, and hirtiiida Knoch are correctly determined. 

 n albina Burm. Known to us but rare. 

 „ rugosa Mels. correctly determined. 

 „ comata Burm. is balia Say. 

 „ qiiercus Knoch. correctly determined. 

 „ lanceolaia Say, under Tostegoptera, correctly determined. 

 The following are described as Trichestes. 

 Z. tristis Fab. correctly determined. 



„ comans Burm. subsequently described as rufiola Lee. determ- 

 ined from a duplicate in Zimmerman's old collection. 

 L. crinita Burm. subsequently described as glabripennis Lee. 

 „ ephilida Say. correctly determined. 

 „ longiiarsis Say. correctly determined by Burm. notwithstanding 



LeConte's opinion to the contrary. 

 /.. prununculina Burm. since described as cerasina Lee. 

 „ gracilis Burm. since described as volvula Lee. 

 „ dispar Burm. Subsequently described as Gynnis debilis Lee. 

 The Revision of the Melolonthidae by Dr. LeConte appeared nearly 

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

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

 ra was then suppressed. The following are the species : 

 I., ventricosa Lee. with cribrosa Lee. as synonym. 

 „ quercus Knoch. correctly determined.
