COLEOPTERA.—LEA. 229 



Hah. — Queensland : Blackall Range. — Type, male and female, C/2325 in 

 Queensland Museum ; eotype, male, in South Australian Museum. 



With the general outlines and appearance of C. tarsalis and C. picticornis, 

 with which it would be associated in my table," but readily distinguished from 

 those and all other described species by the shape and clothing of the hind 

 tibiffi of the male ; the third-sixth joints of antennae of the male have some 

 rather long hairs on the under surface; the tips of the antennae of the female 

 are missing, and only its eighth joint is infuscated. 



MACROGONUS QUADRIVITTATUS Jac. 



Of sixteen specimens of this species before me five have the elytra 

 purple or blue, except that the margins and suture are narrowly flavous ; on the 

 others the blue (sometimes almost black) part of each elytron is divided into 

 two by a flavous vitta, the vitta narrow and hardly passing the middle on some 

 specimens, wider and almost touching the apex on others ; on twelve the basal 

 spot of the head is divided by a narrow longitudinal vitta, on the others the spot 

 is divided into four parts, each of which is hardly more than a stain. 



MACROGONUS BIFOVEICOLLIS sp. nov. 



$ Flavous, elytra dark blue or greenish blue, tarsi coppery green, second 

 to fifth joints of antenna? metallic blue or coppery green, the following ones 

 opaque purple, tips of mandibles blackish. 



Head with a fairly deep interocular impression, connected Math the base 

 by a distinct median line; jouuctures sparse, irregular, and mostly small. Pro- 

 thorax about twice as wide as long, each side Avith a large obtuse median tooth, 

 front and hind angles slightly armed, between median and hind teeth a deep 

 notch ; with a large, somewhat transverse, deep fovea on each side of middle ; 

 punctures sparse and rather small, but sharply defined. ScuteUum triangular, 

 slightly longer than wide. Elytra much wider than base of prothorax; each 

 with four irregular fovea?: two on the sides behind the shoulder, one halfway 

 between the front one of these and the suture, the other slightly nearer the 

 second marginal fovea than the suture ; with regular rows of rather small 

 punctures. Length ((?9 )? 10-5-11-5 mm. 



2 Differs in having the prothorax smaller and less transverse, sides 

 gently rounded and unarmed in middle, notch near hind angles less pronounced, 

 disc nonfoveate, and with slightly larger punctures ; elytra with lateral foveae 

 not traceable, and the others smaller, antenna? and legs slightly shorter and 

 thinner, and knees and most of tibia? dark.
