1921] Boving: Larvae and Pupae of Social Beetles 213 



Eunausihius wheeleri Schwarz and Barber 



(Pupa described from specimens preserved in the U. S. National 



Museum) 



(Plate IX, fig. 23) 



Length, 3-4 mm. Grey. Prothorax with five lateral pro- 

 tuberances well developed, to be seen with naked eye or ordinary 

 lens. (On specimen figured one protuberance was — abnor- 

 mally — not developed on left side.) 



D. — Bibliographical Notes. 



A careful list of the descriptions and figures of the larvae 

 of the family Cucujidae (auth.) , including reference to P. de 

 Peyerimhoff's key for the determination of the larvae of tlu; 

 Cucujid genera, is given by F. H. Gravely (in Records of the 

 Indian Museum, Calcutta, vol. II, 1915, pp. 353-358). 



To this list might be added the part dealing with this 

 family in L. Ganglbauer: Die Kafer von Mitteleuropa, vol. Ill, 

 part 2, 1899. Since the list of Gravely was published an impor- 

 tant work has appeared by U. Saalas: Die Fichtenkafer 

 Finnlands (in Annales Academiae Scientiarum Fennicae Ser. 

 A, vol. VIII, 1917 pp. 508-528, figs. 119-130) . In Saalas' book are 

 described and splendidly figured with habitus and detail draw- 

 ings the following larvae (and pupae) : Pediacus fuscus Er., 

 Laemophloeus abietis Wank, Laemophloeus altemans Er. 



Finally I may mention that the larva described and figured 

 by C. V. Gernet as "Gucujiden-Larve" {Dendrophagus crenatus 

 Payk) is in my opinion a Staphylinid larva of the group 

 Aleocharini. The figure shows the combination of a mandible 

 without mola and jointed cerci, movable at base, which is char- 

 acteristic of the Staphylinids ; and also a large movable labrum, 

 a single ocellus and broad ligula, which characters define the 

 Aleocharini. 



The newest taxonomic arrangement of the Cucujidae is 

 presented by Charles W. Leng in : "Catalogue of the Coleoptera 

 of America, North of Mexico," Mount Vernon, N. Y., John D. 

 Sherman, 1920. The arrangement of the larvae given in the 

 present paper does not agree so well with Mr. Leng's list as 

 with the system presented in 1899 in L. Ganglbauer's "Kafer von 

 Mitteleuropa."
