106 THE REV. F. W. HOPE’S CHARACTERS AND DESCRIPTIONS OF 
duabus rotundatis dorsalibus. Scutellum posticé rotundatum, punctatum. Elytra 
coriacea, varioloso-tuberculata, lineis tribus longitudinalibus vix distinctis. Corpus 
infra piceum. Pedes atri. 
This insect was obtained at Concepcion and Valparaiso, on the trunks of trees, by 
Mr. H. Cuming, in honour of whom I have named it. The success of his indefatigable 
exertions in various branches of Natural History, is well known by the extensive and 
interesting collections which he has recently brought to this country. 
The species is remarkable for the form of its armed thorax; and also on account of 
the under surface of the basal joints of the tarsi being smooth and cylindric, and en- 
tirely destitute of the pulvination which exists in most of the Prionide. These consi- 
derations induce me to regard it as the type of a subgenus, to which the name of Acan- 
thinodera! may be applied.

ad antennarum insertiones, foveolaque inter oculos posita. Thorax subquadratus, 
lateribus in spinas duas productis. Scutellum nigrum. Elytra rubro-castanea, 
nigro marginata, lineis quibusdam vix distinctis. Corpus infra nigro-piceum. 
Prosternum inter pedes anticos productum, anticé valdé incisum, posticé atte- 
nuatum et infra mesosternum extensum; hoc etiam paullo porrectum. Femora 
antica parim incrassata, picea. Tibie concolores, ad apicem rufescentes. Tarsi 
ferruginei; anticorum articulus tertius bilobus, intermediorum sub-bidentatus, 
posticorum bifidus bidentatus. 
I have named this insect in honor of Dr. Maximilian Perty ; and propose for it the 
subgeneric designation of Dissosternus?, in allusion to the very remarkable structure of 
the sterna of its prothorax and mesothoraz. : 
Fam. STENocorID&. 
Differing from the greater number of entomologists, I regard the genus Stenocorus, 
'AxavOwos, spinosus; dépn, collum. 2 Avoods, duplex; orépvoy, sternum.
