Agrees in all its generic characters "svith Eu. undatus and 

 Amazonicus, even to the sharp keel of the mesosternum ; 

 but differs totally in facies, owing to its rather more con- 

 vex elytra and shining coppery-brown colour, without any 

 variegation. The short stiff black bristles are implanted 

 in regular rows on the elytra. 



Cymatonycha, nov. gen. 



Genus intermedium ; subfamiliis Estolince, GrylUcincB 

 et HehestolincB a^qualiter affine. Forma corporis Gryl- 

 licce similis ; sed uuguibus tarsorum basi leviter dentatis, 

 tibiisque intermediis extus emarginatis. Caput retrac- 

 tile ; inter antennas triangulariter concavum. Thorax 

 subovatus, inermis. Elytra ad humeros lata, delude usque 

 ad apices attenuata. Antennae filiformes, ciliatfc, scapo 

 cylindrico, basi extus subito angustato. Acetabula inter- 

 media vix aperta. Mesosternum fortiter tuberculatum. 

 Pedes subelongati ; femora gradatim clavata. Tarsi ro- 

 busti ; ungues divaricati, prope basin intus breviter late 

 dentati. Tibiae intermedia) extus emarginatte. 



The plain-coloured insect forming this genus is interest- 

 ing as fiirnishing a connecting link between the three sub- 

 families mentioned above, and as probably indicating the 

 true point of transition fi'om the Lamia to the Saperda 

 type. The rounded thorax and trigonal elytra, so much 

 wider at the base than the thorax, give it some general re- 

 semblance to the testacea group oi Leptura. The thorax 

 might be described as subcylindrical, with the sides some- 

 what regularly and strongly rounded. 



C. ca^^anea, n. sp. Fusco-nigra; thorace fusco-castaneo, 

 elytris rufo-castaneis ; subtilissime griseo-pubescens ; capite 

 Igevi ; thorace disperse fortiter punctato ; elytris apice late 

 truncatis angulis externis dentatis, supra sparsim punctu- 

 latis subnitidis, nigro-setosis. Long. 5| lin.

The affinity to the GrxjlliciiKR consists in the general 

 form, and strong concavity of the crown ; but the inter- 

 mediate tibiae in that group are entire. The broad but
