CHIOCEUIS. 73 



one or two rows of punctures visible ; the eljtral puncturation is 

 equally variable but generally rather strong over the base, 

 gradually diminishing posteriorly. The colour varies from flavous 

 or fulvous to piceous, and this applies equally to all the parts. The 

 general shape of the insect is broad and robust ; the thorax has 

 rounded anterior angles but sometimes these are furnished with a 

 tubercle, almost justifying the separation of the specimens so 

 modified as different species; however, so many intermediate 

 varieties occur that nothing is gained by dividing these forms. This 

 species has an enormously extended range which makes it all the 

 more difficult to fix on characters which are so variable, and which 

 increase of material seems only to multiply.

Of brick-red or flavous colour ; the antenna?, body beneath and 

 the legs piceous. 



Head strongly constricted posteriorly : the vertex convex with 

 a deep central groove ; antenna? very robust, the terminal joints 

 strongly subquadrately widened, the second to the fourth joints 

 gradually broader. Thorax rather less depressed than in C. 

 impressa, the anterior angles thickened and tuberculate at the 

 sides, the disc with a single row of punctures (sometimes absent). 

 Elytra with the basal portion strongly raised, this portion with 

 several rows of strong punctures (each row of about 5 or 6 

 punctures), the rest of the surface very finely punctate, the sides 

 and apex nearly impunctate. Abdomen with patches of golden- 

 yellow pubescence. 



Length 8-9 mm. 



Hab. India; Ceylon; Java. 



This species seems nearly as variable in regard ^to coloration 

 and partly in sculpture as C. impressa. The Indian specimens 

 cannot be separated as so many intermediate forms occur ; the 

 smooth sides and apex of the elytra will however, best distinguish 

 this species, but in Javan specimens the basal portions of these 

 parts are generally more highly raised than in those from India.

 Reddish-brown ; femora stained with aeneous. 



Head with a deep central groove, the vertex slightly raised, 

 with a few fine punctures : antenna? with the third and fourth 

 joints transversely subquadrate, the following three joints sub-
