Hah. Siam. 



Clothed with a pale grey pubescence, having spots and 

 patches of black. Head with very large eyes, and conse- 

 quently a narrow front ; vertex longitudinally sulcate. 

 Scape of the antennse faintly grey at the base, the apex black 

 and with a small tuft of black hairs ; the second and bases of 

 the following joints pale grey, their apices black ; third joint 

 at its apex with a tuft of black hairs almost entirely sur- 

 rounding it, the fourth also slightly villose at its extremity. 

 Head and thorax above thickly dotted with small black spots. 

 Elytra granulate at the base ; a black patch covering the 

 shoulders and extending inwards almost as far as the scutel- 

 lum, the latter dark grey ; four velvety black spots or patches 

 along the margin of each elytron, tlie largest at the middle, 

 and four spots on each along the suture. The body under-

By its very large and approximate eyes this species differs 

 from most species of the genus : in this, as in some other 

 respects, it seems to come close to A. Voetii, Thorns. 



Coelosterna {Lamia) pulchellator, Westwood, which appears 

 in the Munich Catalogue under Batocera, has been referred 

 by Ritsema to the genus Ptiaroinaia, while it is redescribed 

 and figured by Aurivillius as Euoplia argenteo-maculata 

 (' Entomologisk Tidskrift,' 1887). Its true affinity is with 

 the species Cjavana and C ylagiata. 



Monohammus cartssimus, Pasc, is a Ccelosterna, for which 

 C. tessellata^ White, is a synonym. 



Coelosterna imitator^ Wliite, is a Cyriocrates, and closely 

 enough allied to C. Borsfieldi^ Hope.
