4(54 Mr. Curtis's Descriptions of 



manded H.M.S. ' Beagle,' was taken at Valparaiso. Its bright rusty legs will 

 distinguish it from Mr. Waterhouse's IV. Darwinii.

 Leevis nigra, elytris latissimis ovatis orbicularibusve rugosissimis : rugis ver- 

 sus suturam lineas longitudinales effbrmantibus (Tab. XLI. fig. 12.). 



Length of male 8, female 9 lines ; breadth A\ to 6. 



Shining black : clypeus emarginate, punctured, with a transverse impression at the base : 

 thorax transverse, a little narrowed in front, which is broadly concave, forming pro- 

 minent trigonate angles, the sides very convex and granulated, narrowed towards the 

 base, which is bisinuated and forming triangular ovate angles ; these have sometimes 

 2 or 3 transverse impressions; and the lateral margins are rugose in one specimen, 

 with a fovea on each side : elytra convex, ovate in the male, orbicular and twice as broad 

 as the thorax in the female ; they are exceedingly rugose, formed by deep dull furrows, 

 having elevated crumpled shining lines, which take a longitudinal direction next the 

 suture, and an oblique and transverse one, to a greater extent, from thence to the outer 

 margin ; the apex is narrowed and winged, forming a subtrigonate granulated tail ; in- 

 flected margin rugose, excepting the base ; pectoral lobe coarsely punctured, with an 

 elongated horseshoe impression ; the pectus and abdomen, excepting the two apical seg- 

 ments, rugose-striate : tibiae externally rugose, anterior with a short external spine. 

 My specimens of this very distinct species were taken at Cape Gregory by 



Lieut. Graves. Mr. Darwin's was found at Cape Negro.

 Nitide nigra, elytris suborbicularibus caudatis lineis elevatis versus suturam 



obliqnis ad marginem exteriorem curvatis profunde insculptis (Tab. XLI. 



%. 13.). 

 Length 9 lines, breadth $f. 



Shining black, like ebony: clypeus punctured: thorax transverse, broadly emarginate and 

 narrowed in front, forming trigonate angles : sides very convex, the margin granulated, 

 narrowed behind, the angles trigonate but rounded, base bisinuated, a strong transverse 

 impression close to the anterior margin, and sometimes a ridge forming a double mar- 

 gin to the sides, but vanishing anteriorly: elytra nearly orbicular, convex, finely and 

 deeply sculptured, forming 10 or 12 clean-cut elevated rays, branching from the suture 

 and bending to the tuberculated outer margin, where many of them are furcate; the 

 apex is pointed and winged, the margins being broad, flat, somewhat cordate and gra-
