series. Geoffrony's name Tritoma must be restored to the typical genus 

 Mycetophagus, hence I have altered the family name. 



ClOID.K. 



Anterior coxae oval, not prominent, cavities closed. 



Ventral segments 5, 1st elongate. 



Tarsi 4-jointed, spurs not distinct. 



Antennae 8-10-jointed. 



This family cannot belong in the Serricornes, which all have the coxal 

 cavities open ; it appears to me to form a distinct family near Cryptopha- 

 gidce and Mycetophagidcs, and this view is confirmed by the larva?. It 

 differs from the Bostrychidm by the coarsely granulated eyes and distinct 

 epipleuras continuous to the apex of the elytra. Endecatomus as re- 

 marked by Leconte is an ordinary Bostrychid. 



EROTYLID.B. 



Anterior coxae globose, separate, cavities generally closed. 



Posterior coxae transverse, not reaching the margin. 



Ventral segments 5, 1st elongate. 



Tarsi 5-jointed, 3d emarginate above for the 4th, which is very minute. 



The coxal cavities are open in Languria which otherwise accords. 

 The 4th joint of the tarsi becomes less minute in Dacne and Combocerus. 



It is evident that this family must come near Cryptophagida where 



Thomson and Bedel place it. It has no sort of affinity with Chrysomelidce. 



The strongly securiform maxillary palpi render most of the genera 



very distinct. 



Atomariid.e. 



Anterior coxae small, globose, or oval, separate, cavities variable. 



Ventral segments 5, equal, or with the 1st longer. 



Tarsi 5-jointed ( % sometimes 5, 5, 4), tibiae with small spurs. 



In this family I have included numerous apparently discordant ele- 

 ments, but which I have entirely failed to separate into distinct families. 

 The tarsi are generally linear, lobed beneath in Telmatophilus, 4th joint 

 smaller in Silvanus, PsammcBCUs, Biphyllus, etc.; the antennae are 11- 

 jointed and moniliform in Cucujus, generally with 3-jointed club in the 

 rest. The basal joint of the tarsi is very short in Cucujus, long however 

 in Scalidia and most others. The length of the ventral segments is also 

 entirely uncertain. Cucujus shows an evident affinity to Trogosita as seen 

 already by Thomson. 



Monotomixle. 



Anterior coxae small, rounded, separate, cavities closed. 



Ventral segments 5 ; 1 and 5 elongate. 



Tarsi 5-jointed, 4th narrower, 5th elongate. 



Elytra truncate, last dorsal segment visible, eyes strongly granulated, 

 antennae 10-jointed, club abrupt. 



This family was founded by Leconte, and as I think, w T ith reason. The 

 structure of the antennae, the 6th dorsal segment in the £' and the facies
