U. spectans, sp. nov. Sat late ovalis ; minus convexa ; subnitida ; 

 supra sat glabra; ferruginea; capite crebre fortius, prothorace 

 sparsim minus fortiter, pygidio fortiter minus crebre, punctu- 

 latis ; prothorace sat transverse, antice fortiter angustato, 

 lateribus-leviter arcuatis, basi utrinque vix sinuata, angulis 

 anticis acutis vix prominulis posticis rotundato-obtusis; elytris 

 sat fortiter punctulato-striatis, interstitiis sat fortiter nee 

 seriatim punctulatis subconvexis ; tarsorum posticorum 

 articulo basali quam 2''' sublongiori. Long., 34^1.; lat. If 1. 

 Southern Queensland, 



COLPOCHILODES (gen. nov. Sericoidarum). 



3ientum antice sat fortiter emarginatum ; palpi fere ut Frenchellce 

 (labialibus modicis articulo ultimo sat elongato sat cylindrico, 

 maxillaribus sat elongatis articulo ultimo quam prsecedens 

 sat longiori) ; labrum totum plus minusve exstans, antice 

 (superne viso) truncato vel late emarginato ; oculi sat magni 

 nitidi vix manifeste granulati, antice a cantho profunde 

 incisi ; antenna? (speciei typicae) 9-articulatae, clava 3-articu- 

 lata (hac maris angusta elongata quam articuli prsecedentes 

 conjuncti vix breviori, feminse multo breviori) ; prothorax 

 transversus ; elytra geminato-striata ; tibiae anticse extus 

 tridentatse, posticis fere ut Sericesthis (elongatis, gracilibus, 

 intus fere rectis) ; unguiculi simplices ; sterna pilis elongatis 

 dense vestita. 



The species for which I propose the above new generic name 

 cannot be satisfactorily placed in any previously characterised 

 genus. With the general characters in other respects of a 

 Coljyochila it combines the hind tibiae of a Sericesthis, — slender, 

 elongate, and having their inner edge straight, which gives it a 

 facies quite unlike that of either of the above named genera. 

 Besides the species described I have seen two others from W. 

 Australia, but as each of them is represented by a unique female 

 it would not be wise to describe them at present. 



C. raucipennis, sp. nov. Elongato-ovatus ; sat nitidus ; supra 

 fere glaber, sternis femoribusque pilosis; ferrugineus vel 

 piceo-ferrugineus ; clypeo crebre subfortiter, capite postice 

 acervatim minus fortiter, prothorace sparsius (ad latera sat 

 crebre) sat fortiter, elytris sat grosse rugulose, pygidio minus 

 crebre subfortiter, punctulato; prothorace postice haud mar- 

 ginato, sat transverso, lateribus (superne visis) pone medium 

 fere rectis, angulis anticis subacutis minus prominulis 

 posticis rotundato-obtusis, basi utrinque sinuata ; scutello 

 Isevi ; elytris geminato-striatis, interstitiis nonnullis angustis 

 convexis sed sculptura nonnihil propter rugositatem obscura^
