and Colonel Sykes. Lamia reticulator of Fabricius, which is remarkable for its 

 penicillated antennae and truncate elytra, appears decidedly to belong to an- 

 other genus not yet characterized. 



Anoplophora*. 



A new genus of Lamiadce belonging to the third of my proposed sections. 

 The following are its characters. 



Caput quadratum. Antennce corpore dupl6 longiores, ultimo articulo valde 

 elongato. Thorax utrinqu^ spinosus, medio depressus. Elytra antic^ et 

 postic^ fer^ sequalia, apicibus rotundatis. Corpus infra squamosum, pec- 

 tore inermi. Pedes difformes et robusti. 



Anoplophora Stanleyana.

colore imbutis. Caput antic^ maculis binis oblongis coeruleis notatum. 



Antennce nigrse, articulis basi coeruleis, ultimo elongato atro. Thorax 



coeruleus, linea media longitudinali nigra spinisque utrinqufe concoloribus. 



Elytra nigro-senea, nitida, maculis coeruleis aspersa. Corpus infra conco- 



lor, segmentis abdominis postic^ nigro-piceis, femoribus squamosis colore 



beryllino tinctis. Tibiis, tarsis, annulisque antennarum subcceruleis, 



plantis fusco-spongiosis. 



This magnificent insect I have named in honour of the President of the 

 Linnean Society. It is almost impossible to convey by description an idea of 

 the beauty of this species. Its external appearance is of a light beryl colour : 

 when examined under the lens, it has the appearance of mother-of-pearl, and 

 closely resembles the feathery scales of the Lepidoptera. 



The nature and causes of the colouring matter of insects is very imperfectly 

 understood. 



* From a, not, and 6v\o<l>6pos, an armour-bearer.
