ANNULOSA JAVANICA. 41 



this most difficult family must depend in a great measure on our better acquaintance with their 

 larvae. Perhaps it would be better for the present to consider the typical insects of the groupe as 

 unascertained, and the propriety therefore of the family name Engidce as at least doubtful. It is 

 observable, however, that ail these insects were Dermestes with Linnaeus and Fabricius; and, as 

 in another part of the work I shall have to return to this subject, in<the mean time I shall merely 

 remark, that from the Helopidce this groupe may easily be distinguished by their clavate antennae. 



Genus DACNE Lat. Engis Payk. 

 M. Latreille, in his Precis de Genres founded the genus Dacne on the species of insect 

 called by Herbst, Ips humeralis ; and soon after Paykull, in the Fauna Suecica, gave the generic 

 ivame of Engis, with appropriate characters, to the same insect. Fabricius, in the Systema 

 Eleutheratorum, adopted this genus with the name given to it by Paykull, and placed in it an 

 American insect, the Erotylus bifasciatus of Olivier (Enc. Meth. Hist. Nat.), which insect is, 

 however, sufficiently distinct, by its maxillary palpi having their last joint hammer-shaped, 

 whereas the European insect (Ips humeralis of Herbst) has the same joint only obtusely subu- 

 late. I leave, therefore, the original name of Dacne with the last-mentioned insect, and give 

 the name of Engis to those exotic insects which coincide with Engis fasciata of Fabricius, in 

 the above description of their palpi, ana which differ from true Erotyli, in having the 

 penultimate joint of their tarsi visible, although very small.
