turn, basi crassius. Elytra sequata, prothorace baud latiora. Tarsi 

 arttculo penultimo late bilobo, secundo angusto.

 mutic femora.

 brevis, squamis silaceis griseisque varius ; rostra prothorace breviore ; 

 antennis ferrugineis ; funiculo articulo primo quam secundo fere duplo 

 longiore ; clava ovata, breviuscula ; prothorace valde transverse, antice 

 abrupte constricto, apice fasciculis duabus nigris et pone medium quatuor 

 transversim dispositis, instructo ; scutello parvo ; elytris subcordatis, vage 

 fasciculatis, striato-punctatis, interstitiis plus minusve elevatis, striis 

 squamis elongatis instructis, lateribus plaga limitata alba notatis ; abdo- 

 mine segmentis tribus ultimis, secundoque in medio, nigris. 



Long., ij~ 2 i lin. 



Tairua (Capt. Broun). 



Varies considerably in size and also in colouration. 



890. S. vexatus, Pascoe; Ann. Mag. Nat. Hist., July, 1876. S. 

 oblongus, fuscus, squamis griseis tectus ; rostra prothorace vix breviore ; 

 antennis ferrugineis; funiculo articulo secundo quam primo breviore, 

 clava oblongo-ovata ; prothorace valde transverse, antice fortiter con- 

 stricto, apice bi- in medio quadri-subfasciculato; elytris parallelis, postice 

 rotundatis, impresso-punctatis ; femoribus infra canaliculatis. 



Long., 2f lin. 



Tairua (Capt. Broun). 



Differs from the last in being longer, and the femora being grooved 

 beneath for the reception of the tibiae. In some examples there are, 

 owing to the dense squamosity, two pale oblique spots at the sides of 

 the elytra. 



Crisius. 



Pascoe ; Ann. Mag. Nat. Hist., July, 1876. 



Rostrum modice elongatum, arcuatum ; scrobes praemedianse, rectse. 

 Antenna tenues, funiculo articulo secundo elongate. Prothorax conicus, 

 apice productus. Elytra subcordata, basi quam prothorace multo 

 latiora. Femora clavata, infra dentata ; tibia rectse, posticte extus 

 arcuatae ; tarsi articulo penultimo late bilobo. Rima pectoralis ad coxas 

 intermedias postice extensa. 



This is obviously an Acalles form ; but the elytra greatly exceeding 

 the prothorax in breadth, and other characters, will not allow it to be 

 referred to any known genus. 



891. C. binotatUS, Pascoe; Ann. Mag. Nat. Hist., July, 1876. 

 C. fuscus, squamis obscure griseis vestitus ; rostra prothorace longiore, 

 versus apicem sensim latiore ; antennis ferrugineis ; funiculo articulo 

 secundo quam primo duplo longiore, sequentibus sensim brevioribus ;
