testaceo marginatus, creberrime punctulatus ; elytra prothorace non 

 latiora, quam lata plus duplo longiora, pone basin sensini ampliata, 

 infra medium angustata, nigra, utroque prteterea seriebus tribus e 

 punctis nonnihil evidentioribus formatis, basi fascia insequali, extror- 

 sum latiore, non usque ad suturam continuata, maculisque pone mediimi 

 quatuor flavo-testaceis ornata, tribus prope marginem lateralem, quarum 

 prima mox pone medium, subrotunda, reliquis majore, secunda inter 

 medium et apicem, tertiaque prope apicem, parvds, ilia subovata, hac

 suturam locata. 



The above is a transcript of Boheman's description, in his work on 

 new species of insects discovered during the voyage of the Swedish 

 frigate ' Eugenies,' 1851-1853. I am indebted to Mr. Janson for a 

 reference to this work. The species is unknown to me.

 palpis, antenuis, abdomine pedibusque testaceis ; prothorace subtilissime 

 crebre punctidato, utrinque late flavo-testaceo marginato ; elytris sub- 

 tiliter creberrime punctulatis, margine laterali maculaque disci exte-

 versus valde dilatatis, valide dentatis.

Caput pariun convexum, inter oculos utrinque leviter impressum, 

 antice rufo-testaceiun, rotundatum: prothorax longitudine duplo et 

 dimidio latior, apice late leviter rotimdo emarginatus, lateribus pone 

 apicem leviter rotundo-ampliatis, dein basin versus oblique dilatatis, 

 angulis anticis antrorsimi prominulis acuminatis, posticis retrorsum non- 

 nihil productis ; supeme paulo convexus, extrorsum late flavo-testaceo 

 marginatus : elytra prothorace parum latiora, quam lata duplo longiora,

The above is condensed from Boheman's description. I do not 

 know the species. ^
