bacher (No vara Reise, p. 127) under the name of Diceroderes 

 elongatus. Diceroderes is a remarkable Mexican form referred 

 by Lacordaire to Eutelinae, which is differentiated, inter alia^ 

 from the Bolitophaginse by their short metasternum, elytra 

 without epipleurte, and globose anterior coxae ; the hook to 

 the internal maxillary lobe is also given as a character of the 

 Eutelinaj ; but it is absent in Diceroderes, as in the Bolitopha- 

 ginje. The species described below differs principally from 

 D. elongatus in having larger tubercles on the elytra, and the 

 prothoracic horns, instead of being lyrate, are simply curved, 

 approaching a little at the tips, shorter, and stouter at the base. 



Dysantes taurus. 



D. minus elongatus, fuscus, antennis ferrugineis, articulo quarto quam 

 sequente longiore ; prothorace supra quadrituberculato, cornibus 

 vahdis, tuber ciilatis, intus arcuatis, apicibus paulo approximanti- 

 bus ; elytris seriatim grauulatis, granulis approximatis, tuberculis 

 elongatis uumerosis interjectis ; corpora infra subtiliter punctu- 

 lato. Long. 4| liu. 



Hah. Java. 



Calymmus. 



(Bolitophaginse.) 



Caput antice angustius, sutura clypeali semilunari. Oculi reni- 

 formes. Palpi maxillares articulo ultimo subsecuriformi. An- 

 tennce clavatse, ll-articulatae, articulo basali paulo incrassato, 

 tertio sequentibus longiore ; clava triarticulata, articulis trans- 

 versis, ultimo prgecedente haud distincto. Proiliorax transversus, 

 lateribus crenatus, antice in laminam elongatam productus, basi 

 bisinuatus. Scutellum distinctum. Elytra oblonga, parallela, 

 prothorace vix latiora ; epipleura postice obsoleta. Pedes sub- 

 tenues ; femora subfusiformia ; tibice marginibus teuuiter granu- 

 latis, margine interiore recto ; tarsi breviusculi. Prosternum 

 postice verticale, apice in incisuram mesosterni recepto. Epipleura 

 metathoracis distincta. 



This is one of the genera of Dejean's Catalogue which 

 seems never to have been described ; but it finds a place excep- 

 tionally in Gemminger and Von Harold's great work, in conse- 

 quence of Montrouzier's Toxicum Berardi being referred to it 

 by Perroud. This species, according to a specimen in the 

 British Museum, has an antennal club of six joints, and 

 therefore has nothing to do with Calymmus.
