Lea — On Australian CoLEOt-TERA 279 



Prothorax scarcely twice as wide as tlie median len^h, sides evenly rounded, 

 front angles unarmed ; with dense and fairly large pnnctnres becoming crowded 

 on sides, interspac-es with minute punctures. Scutellum impunctate. Elytra 

 with punctures fairly large throughout and in places transversely confluent, but 

 with an impuncitate line on each from base to apex, and remnants of tAvo others. 

 Abdonu'n with fairly dense, more or less asperate punctures, in places finely 

 strigose; apical segment with a wide median fovea, its middle rather deej). 

 Femora stout, edentate; hind tibiae moderately long, slightly dilated to apex, 

 inner edge straight almost throughout. Length, 7 -5-8 -5 mm. 



? Differs in being more robust, prothorax more transverse, abdomen more

In my table would be associated with G. hardcastlei, from which the male 

 differs in having smaller eyes, prothorax more rounded in middle, and basal 

 segment of abdomen in parts densely and finely striated, and with more numerous 

 punctures. The head of the male has been damaged, and its antennae and palpi 

 are missing ; on the female the antennae are of a dingy flavous, with the tips of 

 five joints infuscated; its palpi are entirely flavous; on both specimens there is 

 a short, impunctate, median line, near the base of the pronotum.

Head Avith crowded and sharply defined punctures, but in places confluent; 

 Avith a vague median line. Antennae long and thin. Prothorax about once and

 armed; Avith croAvded ])unctures, slightly larger than on head. Scutellum im-

 AA'hich are transversely confluent, but lea\nng some feebly defined impunctate

In general appearance very close to the preceding species, from AA'hich it 

 may l)e distinguished by the abdominal fovea ; on the present species this is fairly 

 deep and extends as an even impression across more than one-third of the seg- 

 ment ; on that species it is suddenly deepened in the middle, the deep part being
