Genus. — Colobus, Serville. 



This genus is placed by Serville, 'Ann. Ent. Soc. of France,' ii. 

 554, next to Callichroma, which, in some of its characters, it appears 

 a good deal to resemble, and its connection with the present family is 

 solely dependant on its abbreviated elytra : the typical, and indeed 

 the only species, is Colohus hemipterus, the Stenocorus hemipterus of 

 Fabricius, ' Syst. Eleu.' ii. 310, and the Cerambyx hemipterus of Oli- 

 vier, iv. (Capr.) 127, No. 172, tab. xxiii. fig. 181. It inhabits Java, and 

 appears to be a rare insect : there is a fine specimen in the cabinet of 

 the British Museum. 



The genera which follow have no reference to any particular family 

 of Longicorns, but are simply recorded as supposed novelties to the 

 science. 



Genus. — Chion, Newman. 



Antennae maris coi-pore duplo longiores, graciles, articulis apice 

 fere in dentem productis : prothorax fere rotmidus, dorso paullo con- 

 vexus, lateribus spina acuta mediana armatis : elytra ampla, linearia, 

 abdomen tegentia, apice truncata, singulo angulo spina acuta armato : 

 pedes simplices, femoribus nullo modo armatis. 



Chion rusticiis. Testaceus, prothorace pedibusque saturatioribus : 

 oculis fuscis, subtiliter ac creberrime punctus, lanugine testacea 

 undique tectus. (Corp. long. "9 unc. lat. '2 unc. antennarum 

 dilat. 3"75 unc.) 

 Stenocorus riisticus, Fabricius, ' Syst. Eleu,' ii. 311. 



Inhabits North America, not India as Fabricius has said. The spe- 

 cimens in the cabinet of the Entomological Club were taken by Messrs. 

 Doubleday and Foster, at St. John's Bluff, in East Florida.

 It should be observed in defence of this new genus, that Audiuet-
