elytra with numerous small ones on the interstices; apical 

 joint of maxillary palpi less securiform, and inter-coxal pro- 

 cess of prosternum very feebly grooved. From olivacea it is 

 also readily distinguished by the punctures and by the elytral 

 margins. The inter-coxal process rapidly slopes downwards 

 from its middle, so that at its apex it is not conspicuously 

 elevated above the adjacent parts, simply being the summit 

 of two sloping sides. 



Stethomela flavomarginata, n. sp. 



Dark reddish- (almost chocolate-) brown, parts of under- 

 surface and of legs, more or less obscurely diluted with red ; 

 palpi, basal joints of antennae (the others almost black), and 

 parts of elytra flavous. 



Head with numerous but rather small punctures; clypeus 

 almost on the same plane and with similar punctures to rest 

 of head, suture fairly distinct but rather feebly depressed. 

 Antennae long and thin, none of the joints transverse. 

 Prothorax more than thrice as wide as long, sides evenly 

 rounded, front angles acute, a shallow depression near each 

 side ; with numerous small or medium-size punctures somewhat 

 irregularly distributed, some large ones on each side in front. 

 Elytra at base slightly wider than prothorax, sides gently 

 dilated to beyond the middle and then widely rounded ; with 

 regular rows of not very large punctures, and with numerous 

 small but distinct punctures on the interstices. Char* 

 strongly and acutely dentate. Length, 7^-8^ mm. 



Ilab. — Queensland: Cairns (F. P. Dodd, E. W. Fer- 

 guson, and A. M. Lea). Type, I. 4874. 



A very aberrant species, for which perhaps a new genus 

 should have been proposed; the apical joint of the maxillary 

 palpi is unusually wide, and the subapical joint (which is 

 somewhat triangular) of different shape to that of any other 

 species that I have seen. At first glance it appears like an 

 aberrant form of Paropsis, (30) but the palpi, inter-coxal 

 process of prosternum, and elytral epipleurae are very dif- 

 ferent to those of that genus. The shape and punctures of 

 the head and prothorax are much like those of rufimana. 

 The inter-coxal process of prosternum is unusually wide and 

 almost perfectly .flat throughout ; in front it appears to form 

 the flattened culmination of two slopes, instead of being 

 conspicuously elevated above the adjacent "parts; its base is 

 orntly incurved to middle. The elytra are without post- 

 humeral impressions ; their epipleurae ar# flat towards the 



(30) From examination of the upper-surfnce only, it might have 

 been referred to Group 5 (formerly 6), Subgroup 1, of that genus.
