of the terminal joint of the antennae. It will also be seen, (notwithstand- 

 ing Dalman expressly says, " Tarsi omnes exacte 4-articulati, absque 

 " rudimento nodi basilaris in articulo unguiculari, subtus ciliati non vero 

 " spongiosi,") from the fig. 3, D, that there is a rudimental basal 

 joint in these organs which will also further exhibit their affinity with the 

 genus Catogenus. Dalman was evidently led into this error from an idea 

 that if any rudimental joint actually existed it would be the fourth, as 

 in Parandra and the Longicornes, and not the basal joint. 



Of this genus there are four species contained in the cabinet of the 

 British Museum ; and Messrs. Hope and Children have respectively spe- 

 cimens of another species, which the former gentleman received from 

 Dr. Klug, under the name of Pass, vittata. 



The species all agree in being less depressed than either Cucujus or 

 Catogenus, and also in having the elytra but partially striated, the disk 

 of each being smooth and shinins:. 



The next genus to which I beg to call the student's attention is that of 



Dendrophagus, Gyll., 



chiefly on account of its approaching the preceding genera not only in 

 its elongate form but also in having the " tarsorum articulus primus mi- 

 " nutus, inferus," Gyll. 



As Gyllenhal has not stated that the underside of the head of this genus 

 is produced as in the preceding, we may conclude that it is formed as 

 in the subsequent genera.* Still if we notice the similarity in 

 the structure of the trophi themselves, (especially the maxillae and 

 maxillary palpi, and the labium and its appendages,) in Catogenus, 

 Uleiota. and Cucujus, we shall soon be convinced of the real approxi- 

 mation between the genera, notwithstanding the variation in the structure 

 of the underside of the head. 



The type of the genus Dendrophagus is theEuropean species, crenatus; 

 but the British Museum cabinet contains three species (arranged under 

 Brontes,) one of which is a remarkable insect. 



Although differing in its elongated form and shorter antennae, yet in 

 the majority of its characters, and more especially in the formation of
