proportionally larger ; above, all the body and especially the elytra 

 are decidedly depressed. Length 3i lines. 



BUCTNTHIA. 



Caput antice quadratum. Oculi parvi, remoti. Antennas graciles, fim- 

 briatse, basi distantes ; scapo raodice elongato, apice subproducto, ob- 

 solete cicatricoso ; articulo tertio multo longiore, sequentibus gradatim 

 brevioribus. Prothorax transversus, lateribus minute dentatus. Elytra 

 subdepressa, ovata, prothorace valde latiora. Pedes mediocres, fere 

 sequales : tarsi parvi. Prosternum simplex. Mesosternum elevatum, 

 antice subdentatum. 



The only species constituting this genus was originally referred 

 by me to Zygocera, with some of whose members, as the genus 

 then stood, it has a considerable resemblance in form and colour. 

 The widely separated antennae at tbe base, however, show that it 

 should be referred to the Mesosince rather than to the Hypselo- 

 mincs, to wMch I consider Zygocera belongs. The type is Bucyn- 

 tJiia sjpiloptera, Pasc, {^Zygocera) . 



Stmphtletes devotits. 

 S. subangustus, ferrugineus, pxibe brevi, densa, subsericea tectus ; pro- 

 thorace subtransverso, antice paulo constricto, ad latera irregulariter 

 rotundato, disco tuberculis quatuor parvis instructo ; elytris subparal- 

 lelis, apice subtruncatis, basi leviter tuberculato-cristatis, pone medium

 Hob. Western Australia (Perth) [Mr. Buhoulay). 



Rather narrow, ferruginous, covered with a short, dense, somewhat silky, 



greyish pile ; head rather narrow in front, median line glossy black 



and very distinct ; prothorax subtransverse, a little narrower anteriorly, 



the sides irregularly rounded, the disk with two transverse tubercles, 



behind these two others not quite so prominent ; scutellum scutiform; 



elytra subparallel at the sides, the base broader, with two or three 



black shining tubercles on each, the apex rounded, behind the 



shoulder, at the side, a pale patch, which is nearly connected with a 



broad obhque irregular band behind the middle ; body beneath with a 



long, gre3dsh, silky pile ; legs and antennae closely pubescent, greyish, 



tinged with brownish yellow. Length 9 lines. 



The pubescence is more silky than is usually met with in this 



genus ; the species is otberwise very distinct, although, from its 



general appearance, it may be placed with 8. munitus, 8. sodalis, 



S. ingestus, and others.
