medium sitis), in media parte disjunctis fractis, ornata ; vix den- 

 sius et profundius punctata, sed punctis in seriebus longitudinalibus 

 haud dispositis ; ad apicem ipsum truncata et conjunctim leviter 

 emarginata. Antennae fere corporis longitudine, nigrse, articulis

This beautiful Coleopterous Longicorn has been recently sent 

 to England from Cambogia, the fertile region situated between 

 Siam and Cochin-China, on the eastern coast of the Indian 

 Ocean. It appears to be a normal representative of the genus 

 Abryna of Newman, though in its external fades somewhat re- 

 sembling an Agelasta. Apart from other differences, however, 

 the members of the genus Agelasta have no tooth at the sides 

 of their prothorax (although one or two species have something 

 approaching to a tooth, in the shape of a small tubercle) ; 

 whereas the Abryna have two teeth, well pronounced, the one 

 above the other — as in the Abryna Regis-Petri. Moreover the 

 Abryna are narrower and more cylindric insects than the Age- 

 lasta. The A. Regis-Petri is a very interesting and important 

 species, and one which at first sight somewhat resembles the 

 large Agelasta bifasciata, White, an insect which occurs in 

 Northern India ; however, the generic characters of the Abryna 

 Regis-Petri, specified above, will at once distinguish it from 

 that species. 



Genus Niphona, Dejean. 



Niphona Regis-Ferdinandi, Paiva. 



N. nigra, squamulis demissis ferrugineis plus minus tecta et irrorata, 

 profunde et dense punctata ; prothorace inaequali, longitudinaliter 

 profunde subsulcato (sulcis interruptis irregularibus), ad latera 

 versus angulos anticos bituberculato ; elytris postice paulatim 

 acutiusculis, punctis squamosis vix albidioribus parce irroratis, ad 

 apicem ipsum truncatis pilosis et singulatim emarginatis ; tarsis 

 latis. 



Long. corp. lin. vix 10. 



Habitat in Cambogia, una cum prsecedente degens. 



Regi Ferdinando Saxe Coburgi Gothse, artium liberalium et agricul- 

 tural insigni cultori et etiam patrono generoso, hanc Niphonam 

 novam et formosam necnon valde anomalam, ob gratiam nobilitatis 

 mihi regie collatam, grato animo libenter dedicavi. 



N. sat angusta, postice paulatim et distincte attenuata, profunde et 

 dense punctata (punctis magnis, latis, subconfluentibus), nigra et 

 squamulis demissis ferrugineis plus minus tecta et irrorata. Caput 

 deflexum, in medio canaliculatum, labro (sed preesertim clypeo) dilu- 

 tiore subflavescente, instrumentis cibariis piceis. Prothorax antice 

 et postice constrictus, valde insequalis, punctis maximis profundis 

 et sulcis interruptis irregularibus longitudinalibus impressus, versus
