Type : Arrori/rtidits Josciatus sji. nov. 



Tbe species for which I have to propose this now gcuus bears a close resem- 

 blance in the i)attern of the elytra to some sjjeeies of Acron/rta Pasc. (p. e. A. tomii- 

 spinosa Pasc), but it docs not fit into tbe group " C'lytides " as tiie anterior coxae 

 are angular exteriorly, nor into the grouji " Hetero])sides " as the intermediate coxal 

 cavities are open. It will be placed best after Callic/iromopiiis in the group 

 '• Compsoc^rides" with whicli it agrees in the open intermediate coxal cavities, 

 angular anterior coxae, triangular last joint of the maxillary jialiji, shortly spined 

 intermediate joints of the antennae, and other cliavacters.

 (PL XIII., fig. 10.) 



?. A. nigcr, dense cinereo-pnbescens, pnbe totam sculi)turam obtegente. Palpi 

 brnnnei. Elytra fasciis trilnis nigris ornata, prima postbasuli in utris(|ue elytris 

 ab margine laterali parum oblique versus suturam descendcntc, juxta sutunim 

 angnstata, in sutura ipsa usque ad scutellum ascendente, hac parte postscutellari 

 recta ; fascia secuuda mediana in disco utriusqiic elytri antrorsum dilatata, hac parte 

 versus suturam curvata ubi angnstata, suturam in tertia parte liasali attingente ; 

 fascia tertia recta, in sutura parum angustiore, in tertia parte ajiicali sita. 



Long. 15 mm., elytr. 11, lat. 3i. 



The median band of the elytra touches the suture only before the middle, and 

 resembles somewhat a mitre.
