species are unrecognizable from description owing to uncer- 

 tainty as to the sex of the type, a point wliich can always be 

 ascertained with very little trouble. These characters also 

 form a more natural and useful basis of subdivision than 

 those which have been employed. 



The proper allocation of the species between the genera 

 Calloodes and Anophgnathiis has vexed the minds of all who 

 have dealt with these insects, partly owing to the rarity of the 

 t^'pe species of the former genus, but also through oversight 

 ot the sexual differences, which has led to forms of very varied 

 type being assigned to it by different authors. Examination 

 of both sexes of Calloodes grayanus, White, shows it to 

 possess, in common with its immediate allies, peculiarities in 

 the form of clypeus and tibia which quite clearly separate them 

 from all other forms. 



To set this matter at rest I shall for the first time formally 

 characterize this genus, drawing up the diagnosis from White's 

 type (which is a female) and a male of the same species. 



Calloodes. 



Regulariter ovatus, subdepressus. Clypeus utroque sexu brevis 

 recte truncatus, margine rei3exa ; maris angulis minus rotundatis, 

 margine magis reflexa. Prothoracis margo postica ante scutelluoi 

 profunda excisa, ad emarginationis latera acute angulata. Tibiae 

 antieae edentata?, latere externo maris recto, feminae leviter bi- 

 sinuato. Processus mesosternalis longus, validus, fere rectus. 



The known species of this genus are grayanus, White, 

 Rayneri, ]\lcLeay, and Atkinsoni, Waterhouse, all otiiers 

 assigned to it being entirely different in essential characters. 

 Mr. Blackburn, who last attempted to define the genus, 

 although believing he knew all the species, had evidently 

 seen none of these three, for he finds the principal generic 

 characteristic to be the possession of " genuinely metallic " 

 colours, whereas all are unmetaUic green. 



I may note that G. grayanus has a cleft claw to the front 

 tarsus in the female, while in the other species all claws are 

 undivided in both sexes. 



The following new species of Anoplognathus may be 

 described here : — 



Anoplognathus luridus, sp. n. 



Breviter ovatus, brunneus : capita, prothorace, scutello, pygidio,
