sand-burrowing species, the prominent prosternal keel is 

 without doubt very useful. 



1. Eretmotus corpidentus^ sp. n. (PI. XIX. fig. 1.) 



Orbicularis, couvexus, niger, nitidus ; pedibus, ore, antennisque rufo- 

 piceis ; corpore subtilissime punctato, prosterno striis, antice evau- 

 escentibus, basi divaricatis. 



L. 3i mill. 



Orbicular, convex, black, sinning ; the head carinate at the 

 sides, feebly punctulate ; the thorax finely punctulate, anterior 

 angles less produced than in E. Lucasi^ much less produced 

 than in E. cirtenst's, posterior fovea shallow ; the elytra with all 

 the striffi short and nearly obsolete ; propygidum and pygidium 

 finely punctulate ; the prosternum wide, with the striaj well- 

 marked at the base, widening out behind the coxae, anteriorly 

 evanescent before the suture, punctuation fine and scattered. 



This species is the largest of the series and is very distinct j 

 it comes nearest to E. Lucasi. 



Found in the plain of Metija. 



2. Eretmotus Lucasi, Mars. (PI. XIX. fig. 2.) 



On the 29th April, and again on the 4th May, I obtained 

 this species just below the cedar-forest on the mountain above 

 Blida. This is probably the same locality in which Lucas 

 found the first specimens in 1857; the locality given by 

 Marseul is Med^ah. The figure is from a specimen I have 

 compared with the type. 



3. Eretmotus cirtensi's, sp. n. (PI. XIX. fig. 3.) 



Suborbicularis, corivexus, niger, nitidus ; corpore modice punctato ; 



prosterno striis fortibus ad basin divaricatis, sparse punctato. 

 L. 2| mill. 



Suborbicular, convex, black, shining, nearly smooth above ; 

 the head feebly impressed before the clypeus, punctures sparse 

 and shallow, bicarinate ; the thorax feebly punctured, anterior 

 angles obtusely produced, with a well-marked fovea within 

 the basal angle ; the elytra sculptured like the thorax, epi- 

 pleural carina well defined, stria? feeble, first one third the 

 length of the elytron, second two thirds, third a little longer 

 than the first; the propygidium and pygidium finely punctu- 

 late ; the prosternum a little rugose, with scattered shallow 

 punctures, the stria3 well marked and widened out at the base, 

 anteriorly continuing to tlie suture. The prosternal striio are
