Lea — On Australian Coleoptera 305 



transverse, ninth briefly obpyrii'orni, .slightly wider and distinctly longer than 

 eighth. Prothorax at base fully four times as wide as the; median lengtli, sides 

 strongly rounded and finely margined, apex deeply emarginate and about half 

 the width of base, base widely bisinuate and fei^bly margined, a deep, narrow, 

 eiirved stria near each side, bnt terminated before middle; ptnictnres incon- 

 spicuous. Elytra scarcely longer than greatest width (at about basal fourth), 

 strongly and evenly convex, sides finely margined: Avith dense and small but in 

 places fairly distinct punctures; epipleurae faintly wrinkled, f(iebly diminishing 

 in width posteriorly. Ijength, 1-5-1 -75 mm. 



Hah. Lord Howe Island (A. M. Lea). Type, 1. 11803. 



A short strongly convex species of which twenty-two spe(;imens were obtained 

 by sieving fallen leaves. The base of the prothorax is very narrowly infuscated ; 

 three specimens are entirely flavous, probably from immaturity ; another has the 

 medio-basal portion of the elytra slightly stained with piceous. The pubescence 

 appears to be easily abraded. 



GEOENDOMYCHUS GLABER sp. nov. 



Castaneo-flavous, appendages slightly paler. Prothorax and elytra glabrous, 

 elsewhere feebly pubescent. 



Head gently convex, a feeble depression near each eye ; punctures 

 inconspicuous. Antennae nine-jointed, two basal joints rather large; club 

 three-jointed. Prothorax at base fully four times as wide as the median length, 

 sides strongly rounded and very finely margined ; apex rather deeply emarginate, 

 a narrow deep line near each side, with which it is parallel, traceable from base 

 to apex; impunctate. Elytra with outlines subcontinuous wdtli those of pro- 

 thorax, sides strongly rounded and finely margined ; with minute punctures. 

 Intercoxal process of prosternum dilated to and truncated at posterior end, a 

 fine stria on each side. Length, 1-3-1 -5 mm. 



Hah. Queensland: Hamilton (C. J. Wild) ; New South Wales : liichmond 

 River, from a nest of termites (A. M. Lea). Type, I. 12020. 



The outlines, under-parts, legs, antennae and palpi are much as in the 

 preceding species, from which it may be readily distinguished by its glabrous 

 upper-surface, and longer sublateral striae of prothorax. 



ENCYMON CLAVICORNIS Blackb. 



Mr. Arrow(5) states that this species is an Encymon; it was originally 

 referred to Mycella, but subsequently made the type of the new genus 

 Cranterophorus. The type was described as blackish-aeneous, with the prothorax
