Tarsi cylindrical. 



Basal joint almost obsolete, not distinct Droiites 



Basal joint small but very distinct, slightly swollen obliquely b(>iieath. 



Deiidropliagus 

 Tarsi strongly dilated ; basal joint small but strongly, oblitiuely produced 

 beneath the basal parts of the second joint. 

 Third tarsal joint obliquely jiroduced beneath in a truncate or rounded 

 lobe; basal joint of the antenna elongate; fourth joint of the maxil- 

 lary palpi large and securiform. 



Antennae slightly thickened toward apex PsailinicCCllS 



Antennse normally filiform thronghout TelepIiailllS 



Third tarsal joint very deeply bilobed ; first antenual joint sliort, oval ; 

 fourth palpal joint slender, conoidal CryptaniOl'pIia 



There can be no dou1)t whatever that these genera should be 

 associated together. The tarsus of Brontes is tru]}' very difierent 

 iVom that of Telephanus, but that of Dendrophagus is a tolerably 

 good intermediate, especially in the structure of the basal joint. 

 The antenna6 are of precisely the same type throughout, and the 

 tarsi are isomerous in both sexes.' The genus Platamus of Erichson 

 is the only one described which is not included in the table ; it is 

 allied to Brontes but differs in its less elongate basal joint of the 

 antennas. 



The Cryptophagidae which are allied to the Cucujidas, but distin- 

 guished by the transversely oval and sometimes distinctly mm-e 

 prominent anterior coxeb, should be composed of the subfamilies 

 Crypto[)hagin9e, Mycetophaginas, Cisinas and Si)hindinae. 



The principal reasons advanced by the earlier systematists, — to 

 whose views Lacordaire deferred somewhat against his will, — for 

 considering the Cisidoe a family of the Serricornia, were in great 

 measure superficial and based upon a general resemblance to the 

 Anobiini, as expressed by the generally cylindrical form of body 

 and somewhat retractile head. On examining the anatomical struc- 

 ture of the under surface I perceive no radical difference whatever 

 between Cis and many of the cryptophagides, and have no doubt at 

 all that the genus is really clavicorn. It cannot be denied, how- 

 ever, that the morphological rcsoni1)lancos to the anobiides above 



' The three specimens of Cnj]tta)iior])1ia desjardetisi {= huhbnrdi Cas.), before 

 me, two of which I believe to be male and female from certain differences in 

 the autennse, have the liind tarsi normally pentamerous throughout. The 

 statement made by Wollaston — apparently with some misgiving — that the 

 tarsi of the male arc heteromerous is open to the gravest doubt.
