whilo the female has the horns short and not branched , and tlio 

 granulation of tlio thorax muck finer tlian in EUiotti. 



Ontlioplmgus amplcxns (n. sp.): Chahjheo-nioer, elytris chahßeo- 

 ficeis; antennis ohscure rußs, clava Jiisca; thorace riigoso-punctato; elytris 

 evidenter striatis et puyictatis; vertice corniibus duohus valde elongatis, 

 curvatis; frothwacc medio in cormi elongatum, rugosiim, lateraliter com- 

 pressttm prodiicto, infra cornu profunde excavato. 5. — Long. 15 mill. 



Clypeus roimded, ratlior rouglily granulatod, tlie vertex witli an 

 erect lamina producod at eacli end into a very long curvod hörn , at 

 tho summit- of the lamina between the base of the horns tliere is an 

 erect, acuminate, triangulär projoction; at the base of the lamina there 

 is a straight, elevated, transverse line. Thorax scabrously punctured 

 in the middle, granulated at the sides, the sculpture absent at the 

 extreme base, the disc prodwced as a long laterally compressed hörn, 

 directed forwards' over the head, and beneath this very deeply exca- 

 vate, the excavation polished and shining; the basal margin is distinct 

 and is a little producod backwards in tho middle. Elytra of a pe- 

 culiar pitchy colour with blue reflection, distinctly striated, the outer 

 Striae less distinct than the internal ones, they are also rather strongly 

 punctured , some of the punctures on the disc taking the form of 

 oblique Scratches, the suture is rather strongly elevated. The pygi- 

 dium is rather coarsely, but sparingly punctured. The under surface 

 is of a shining blue or green colour, the middle of the metastornum 

 is punctured hi front , at the sides and tho extromity leaving the 

 centre smooth, tlie sides of the metastornum are rather closely punc- 

 tured, the punctures bear a fine erect pubescence, the sides of the 

 abdomen are but little punctured; the under surface of tho fcmora 

 sparingly punctured. 



This species was standing in tho Lafertoan collection as 0. am- 

 plecticornis Keiche and indicated as Coming from India, and I have 

 also a spccimen from China. In the Lafertu collection there was also 

 besides the $ individual a female standing to represent the species, 

 but as I am inclined to believe the specimen to be the female of a 

 closely alliod but distinct species , I think it advisablo to leave it 

 without furthor remark than it differs from the fomales of the allied 

 species 0. Mouhoti , victor , EUioti , by having the thorax retuse in 

 front in the middle , and a little projecting over this as a curved
