422 Mr. G. Lewis on new 



suture, anterior lobe punctate ; the mesosternum straight 

 anteriorly, margined with a crenulate stria, which joins a 

 similar one at the metasternal suture ; the anterior tibiae are 

 6-7-dentate, but the tibise are not dilated.

Several specimens. 



Trichoremnus imhricatus, sp. n. 



Ovalis, brunneus, parum convexus : pronoto lateralibus bistriato. in 

 medio grosse ovato-pimctato ; mcsosterno iitrinque bisulcal o ; 

 pedibus valde dilatatis. 



L. If miU. 



Oval, somewhat convex, brown^ shining, sparsely setose ; 

 the forehead densely and minutely rugose, strige sinuous 

 laterally and well-marked, not joining in front, surface 

 with a few large shallow punctures irregularly set ; the 

 thorax transverse, oblique at the anterior angles, laterally 

 bistriate, both stride sinuous, the inner stria touches the 

 outer one at the base, then gradually widens out, leaving 

 a wide interstice behind the anterior angle, where it ceases, 

 the outer stria leaves a somewhat wide interstice between it 

 and the outer edge before the middle, and before the anterior 

 angle it is marginal, and as such ceases behind the eye, 

 behind the eye there is an inner transverse stria which joins 

 the outer stria at the margin, the disk of the thorax has 

 large oval punctures (remarkable for their size), somewhat 

 scattered and irregular, the edge at the base has smaller oval 

 punctures regularly set along it; the elytra — strise, tirst fine and 

 complete, touching the base, second and third shortened and 

 hamate before the base, fourth resembles the third at the base, 

 widening out afterwards into a rather broad shallow groove 

 on the dorsum and ends apically in large punctures, fifth apical 

 and punctiform, sutural is a shallow groove, interrupted 

 narrowly before the base and punctiform apically ; the propy- 

 gidium is microscopically sculptured with a few large shallow 

 punctures, each one bears a seta ; the pygidium is similar ; 

 the prosternum — the anterior lobe is excavated laterally, 

 with a raised median portion, which serves as a prolongation 

 of the keel, keel with setje which seem to follow obsolete 

 striae ; the mesosternum bisinuous, obtusely produced, margi- 

 nate, with two lateral sulci, which are also common to the 

 metasternum ; the 'first abdominal segment has a row of large 

 oval punctures on the anterior edge ; the tibiaj are widely 

 dilated.
