the apex. Anterior pair of thighs thickened, armed l)eneath with a strong tooth ; 

 anterior tibire curved, gradually thickened from base to apex, the latter produced 

 inwardly into a strong spine.

Hab. : Australia, Port Essington. 



Vertex smooth, impunctate ; antennre slender, more than half the length of the 

 body. Thorax longet than broad, subcylindrical, strangulated posteriorly, produced 

 on either side into a large obtuse callosity, basal margin impressed with a deep 

 transverse groove ; disc smooth and shining, nearly impunctate, only a few minute 

 punctures being visible on the sides in front, on the lateral callosities. Scutellum 

 triangular, excavated near the apex, the latter truncate. Elytra broader than the 

 thorax, parallel, obliquely rounded at the apex, the apices conjoined obtusely angu- 

 late ; upper surface deeply foveolate-striate, clothed at the apex with a few coarse 

 hairs. Four hinder thighs armed beneath with a stout spine near the apex. 



DOWNESIA STEIGICOLLIS. 



Filiformis, suhcylindrica, nigra, siihtils nitida, supra sub-opaca, 

 ahdomine Jiavo ; tJwrace suhquadrato, disco utrinque oblique dejlexo, 

 longitudinaliter sulcato-strigoso ; elytris elongatis, profunde punctata'

Hab. : Cochin China. 



Face distinctly punctured between the eyes, vertex smooth, impunctate. Thorax 

 rather longer than broad, subquadrate, sides parallel, very slightly dilated at the 

 base, notched at the hinder angle, the latter armed with a fine lateral tooth ; anterior 

 angles nearly rectangular, their apices obtuse ; basal margin impressed with a deep 

 transverse gi'oove, apical border sub-cylindrical, impressed with a single row of punc- 

 tures ; disc divided on the medial line into two oblique planes, the surfaces of which 

 are closely covered with slightly oblique longitudinal grooved etrigse ; these planes 

 meet at an angle on the middle of the disc, and form at the point of junction a 

 distinct ridge which extends longitudinally for the whole length of the thorax. Scutel- 

 lum small, triangular. Elytra scarcely broader th:in the thorax, parallel, very slightly 

 dilated behind the middle, apices obtusely rounded, each emarginate at the sutural 

 angle, apical margin very finely serrulat e ; above deeply punctate-striate, each elytron 

 with three elevated carinoe, the two inner only visible at the base and apex, apex 

 of suture also carinate, interspaces each with a single row of punctures, hinder 

 half of the second, together with the whole extent of the third, impressed with a 

 second row. Tibire thickened, anterior pair with the upper edge notched, compressed 

 and dilated at the base.
