BXEMA. 279 



480. Exeina ceylonensis, Jac. P. Z. S. 1887, p. 69. 



Black ; head strigose ; thorax with six longitudinal ridges ; 

 elytra with nine or ten tubercles. 



Head closely covered with longitudinal strigaB ; sixth and 

 following joints of antennae transverse. Thorax strongly raised 

 into a pointed elevation, rather closely and distinctly punctured, 

 each side with three longitudinal ridges, the middle pair parallel, 

 not quite extending to anterior margin, second ridge strongly 

 sinuate, third the shortest, only extending to the middle ; inter- 

 stices with some other obsolete elevations connecting the ridges at 

 places. Elytra more deeply punctured than the thorax, each 

 elytron with the following tubercles : one at middle of base, one 

 at shoulders, another near scutellum ; two transverse short ridges 

 near suture, one at middle, the other posterior to the latter, 

 connected by an oblique ridge from basal tubercle to near apex ; 

 another shorter oblique ridge from shoulders to the middle, joining 

 the subsutural one ; a tubercle near apex close to lateral margins ; 

 suture serrate throughout. Underside rugosely punctate. 



Length 2 mm.

Black ; basal joint of antennae obscure flavous. 



Subelongate, slightly constricted at middle. Head strongly 

 rugose-punctate ; antennae black, basal joint flavous. Thorax 

 nearly vertical, the posterior portion strongly raised, rounded, 

 compressed posteriorly into a short perpendicular ridge; top of 

 elevation with two parallel ridges, each connected with a ring- 

 shaped ridge, rest of surface very unevenly rugose and reticulate ; 

 median lobe of posterior margin bidentate. Elytra with a longi- 

 tudinal ridge from middle of base to the middle of their length, a 

 deep, curved, longitudinal depression from below shoulders to behind 

 the middle of suture, a tubercle before and behind the middle at 

 suture, three or four larger tubercles on the apical portion ; inter- 

 stices irregularly punctured and reticulate ; suture entirely smooth. 

 Pygidium with middle and lateral ridges. Body beneath closely 

 rugosely punctured. 



Length 2% mm. 



Hab. Nilgiris (Coll. H. E. Andrewes). 



This small species, the elytra of which have a very intricate 

 system of sculpturing, difficult to describe, may be known by the 

 smooth, not denticulate elytral suture. It differs in this respect 

 from any of its allies recorded from India. I have seen only a 

 single specimen. Lacordaire's description agrees in the main 



points with the specimen before me, obtained in the 



locality.
