colour, by orbits more developed behind eyes, suborbital scrobes 

 not divided by an oblique ridge, palpi more securiform, especially 

 maxillary; prothorax more declivous to posterior angles, antei ior 

 angles more prominent: el3'tra with disc depressed on each side 

 of suture, punctures along sides more closely placed. 



Var. ATROViRiDis, n.var. Colour not so bright as typical form; 

 prothorax and elytra widely margined with green, having no 

 golden tint; anterior angles of head less prominent: elytra not 

 depressed along suture. 



Ilab. — Queensland : Chillagoe District (Dodd). Type in Coll. 

 Sloane. 



Specimens taken by Mr. F. P. Dodd differ considerably from 

 the type of C. longiihini as noted above, but do not seem more 

 than a variety of that species. 



Xoie. — There is a species of Carenum in my collection from 

 North Queensland (my specimens are from Normanton, Ather- 

 ton, and Herberton) which I have ticketed as "C diyylesi Mac\., 

 var. tropicum^' ; it resembles C. lonyulum var. atroviridis so 

 closely in shape and colour, that it is hard to separate them, but 

 differs by having the subocular scrobes divided by an oblique 

 longitudinal ridge; the lateral channel of prothorax shortly but 

 decidedly recurved at anterior angles; legs shorter (especially 

 posterior tarsi); palps less widely securiform. It is possible 

 this may prove to be conspecific with C. angvstifenne Macl., but 

 this could be determined only by comparison with the type of 

 that species, to which I have not access at present. 



Carenum eximium, n.sp. 



Narrow, cylindrical. Head with frontal sulci long, divergent, 

 labrum eraarginate; prothorax as long as broad, parallel on sides, 

 posterior angles rounded, sinuate on each side of wide basal 

 lobe; elytra convex, irapunctate, border folded over and raised 

 at humeral angles ; anterior tibiie '2-dentate. Black ; elytra 

 coppery-green, centre of disc atrous 



Head large, convex (3-2 mm. across eyes), feebly transversely 

 impressed behind vertex; frontal suki long, divergent, extending
