Piceus, clypeo bidentato, fronte tabercalato, tfaorace impreutone cent 

 elytrorum area Bcatellom cingente ttrigaqoe in liagalo obliqol aoda 

 nitide Perragineifl (Tab. XLI. (|g, 1.9). 



Length 10 lines, breadth fully 5. 



Pitchy-coloured, shining; antenna- ferruginous, the dab loogind slender in tin- m 

 female) : head trigonate, thickly punctured with | small pointed tnberele on t! 

 clypeus with the sides sinuated, the apex notched in d. the Mack D 



projecting on either side : thorax thrice as broad as the head, transverse. - 

 truncate, the anterior margin and base both semicircular, with diatii ,<1 punc- 



tures, a broad hollow impression down the centre vanishing behind ; KUftel < 

 gonate, very smooth, the apex ochreoui: elytra much broader than the thorax belnnd 

 the middle, and thrice as long, indistinctly ami irregularly jmnciured. I, uot h 



line down the suture, and 1 others on each elytron: a semicircular bright and deep 

 ochreous space round the scutel, and an oblique four foe 



shoulder, in the direction of the sutural apex, but finishing beyond the middle, * 

 it is dilated and approaches the suture: underside ferruginous-brown, denieh 

 with soft long tawny pubescence ; pygidium exposed, finely punctured ; margin of 

 penultimate abdominal segment ferruginous : leg* of the same colour; thighs short and 

 stout, hinder oval; tibia? short, anterior not broad, tridentato, the others COM 

 punctured and notched externally, with an oblique denticulated ridge on the outside. 



The only specimen in Capt. King's collection is a female, taken at Valpa- 

 raiso. Mr. Waterhouse I find has a male, brought home by Mr. Darwin, which 

 he has described under the name of Chmockeile pitta. I have never - 

 Mons. Guerin's characters of his genus Oiyctomorphut ; but I com hide from 

 his figure of O. bimaculatus, in the plates of the 'Voyage de la Coquille, 1 that 

 our insect may be included in that genus. His species differs from OOn in 

 having- a larger club to the antenna 1 , which i» a lexnal difference, and the ob- 

 lique ochreous stripes on the elytra are wanting ; whereas in Mr. Waterhooi 

 male they are much more distinct and extended than in Capt. King's female, 

 which seems to be intermediate. It is therefore not improbable that they may 

 prove to be one species only.
