Capt. P. P. King's South American Coleoptera. 461 



Similar in form to L. varicosus of Germar, but perfectly distinct; it is of a mud- colour; 

 antennje very short, 3rd joint as long as the 3 following ; head oval ; clypeus with the 

 margin reflexed, obverse-cordate, the 2 lobes covering the base of the antennae, with 3 

 tubercles forming a triangle : thorax twice as broad as the head, somewhat cordate, the 

 sides broadly margined and reflexed, very convex, but suddenly narrowed at the base, 

 which is straight, with the angles acute, concave before, 2 irregular lines of crowded 

 minute tubercles down the disc, and a small patch on each side : elytra considerably 

 broader than the thorax, elongate-ovate, with 5 raised lines on each, the spaces between 

 with 2 rows of indistinct punctures forming transverse waves ; sutural keel not reach- 

 ing the apex, 2nd and 3rd very much raised and presenting a sharp, slightly crenated 

 ridge, 4th forming the margin and uniting with the 2nd at the apex ; the 5th is on th^ 

 inflected margin near to the costa and scarcely raised : legs moderately long and stout, 

 with short pale hairs. 



This genus connects Scotohius and Psammetichus. The fine species de- 

 scribed was taken at Port St. Elena. 



*1]2. Emalodera multipunctata, Curt. 



Nitid^ nigra, punctatissiina, thorace obovato truncato, elytrorum punctis 

 lineas numerosas duplicatas efformantibus ; margine extils apiceqne tu- 

 berculatis (Tab. XLI. fig. 8.). 



Length 5| to 6 lines, breadth 3 to 3^. 



The form of this insect is singular ; it is short and broad behind, regularly tapering to the 

 head, not unlike- a Cychrus: the antennae are shorter than the thorax; head flattened, 

 somewhat hexagonal, irregularly punctured; clypeus emarginate, with a deep curved 

 suture at the base : thorax obovate, being broadest towards the base, with the angles 

 perfectly rounded, the anterior margin concave, covered with punctures, leaving a few 

 smooth spaces on the disc, with a short channel and an impressed line or fovea near 

 each anterior angle : elytra contracted at the base and exposing the scutel, which is 

 exceedingly finely granulated, except at the tip ; they are twice as broad as the thorax, 

 ovate, convex, the apex conical, indistinctly wrinkled, with 6 faint punctured striae down 

 the back, and numerous irregular punctures forming double lines on the interstices ; 

 the 4th, 5th and remaining striae have a line of minute shining tubercles between each, 

 and some scattered over the apex : anterior and posterior thighs with a tooth beneath 

 near the apex. The female is broader and larger than the male ; the thorax is trans- 

 verse and twice as broad as the head, and the posterior femoral teeth form spines. 



Specimens were taken at Port Famine in January, February and March.
