194 REV. F. W. HOPE'S OBSERVATIONS 



A specimen similar to Mr. MacLeay's uniguttatus measures in length, lin. IO5 ; lat. lin. 2. 

 It seems likely that Sten. elongatus of Dejean is the same as the above species. 



Stenochorus rhombifer. 



Steji.fuscus, antennis et corpore sparsim flavo-tomentosis, capite haud villoso, rubro. 



Descr. — Affinis prsecedenti at multo minor. Thorax inaequalis et tuberculatus. Ely- 

 tra depressa bidentata, macula quadrato-elongata lutea fere in medio disci posita. 

 Corpus infra rubro-piceum nitidum, binis ultimis segmentis pallidioribus. Pedea 

 rubro-fusci femoribus parum incrassatis tarsisque infra aureo-tomentosis. 



Long. lin. 7; lat. lin. l^- 



In Mus. Dom. Hope. 



I received this species in a box of insects from Mr. Charles Darwin. Its true locality 

 is either Sydney or Van Diemen's Land. 



I consider it quite distinct from Mr. W. Sharpe MacLeay's Stenochorus uniguttatus. 



Stenochorus tunicatus, MacLeay. 



Sten. jlavus ; antennarum articulis duobus primis nigris, quinto apice, septimo nonoque ni- 

 gris ; thorace subcylindrico utrinque unidentato, supra quadri-tuberculato, tuberculis 

 anticis majoribus ; elytris apice flavis, unidentatis, parte basali ultra medium suhviola- 

 ceo-flava, linea obliqua terminata ; corpore pedibusque Jlavo-testaceis. 

 In Mus. Dom. MacLeay. 



Stenochorus rubripes, Boisduval. 

 Tab. XII. Fig. 4. 

 Sten. elongatus parallelus ; antennis pedibusque rufis ; thorace angustiori, cylindrico, tuber- 

 culato ; elytris dilute fuscis, apice spinosis, punctis crebris impressis, macula communi 

 maxima irregulari, nigra notata, altera postica, scutelloque Jlavis. 

 Long. lin. IQi; lat. lin. 2^. 



Described from Mons. Boisduval's 'Voyage de I'Astrolabe,' vid. part ii. page 479. 

 I had given the name of undulatus to the species, and had figured it before I was aware 

 of its being described : the sexes apparently ditfer considerably in size. 



Stenochorus Roei. 

 Sten. rubro-fuscus ; antennis pallidioribus ; thorace tuberculato, elytrisque macula irregulari 

 flava notatis, alteraque apicali lutea, spinis apice brevibus, externa longiori. 

 Descr. — Corpus infra rubro-piceum nitidum, pedibus concoloribus et tomentosis. 

 Long. lin. 6^; lat. hn. 1^. 



This species was sent to me from the Swan River by Captain Roe ; it is named after 

 that indefatigable and enterprising officer.
