L. 3i miU. 



Oblong-oval, convex above, black, shining ; the head 

 deeply excavated in front and on theepistoma; frontal stria very 

 fine and widely sinuou3, the sinuosity bending towards the 

 neck, near the base of the liead between the eyes is a second 

 well-marked transverse stria, surface feebly and irregularly 

 punctured, some points being small and others larger ; the 

 thorax, anterior angles subfoveolate and somewhat closely 

 punctured, and the punctures on the disk are ratlier sparse 

 and clearly composed of small and larger points, the lateral 

 stria is sinuous and continued behind the neck ; the elytra, 

 str'idd 1-3 and inner subhuraeral complete, 4 rather fine and 

 shortened before the base, 5 apical and nearly half the length 

 of the fourth, sutural complete ; the propygidium punctate 

 (very similar to P. cyanescens, Er.) ; the pygidiura with the 

 punctures fine and more scattered; the prosternum has a micro- 

 scopic strigose sculpture and a few punctures on the anterior 

 lobe, the strige start from the base and gradually meet ante- 

 riorly, there are a few punctures on the keel ; the mesosternum, 

 stria very fine and does not quite meet in front; the lateral 

 striae of the metasternum do not widen out like those of 

 P. cj/anescens ; the anterior tibia has three rather large teeth 

 coequal in size and one small at the base ; the legs obscure 

 reddish brown. 



The species is rather more oblong in outline than P. cyan- 

 escens, Er., and P. congonis, Sch. 



Note. — In P. diversicoUis, Sch., and others, tiie frontal 

 stria is carried in a semicircular form at the back of the head 

 behind the eyes. In P. striaticeps the stria is straight and 

 detached and lies hetioeen the eyes.
