424 MARTIN JACORY 



oblique and thickonod, posterior margin broadly produceil at the 

 middle, the basal sulcus rather deep, strongly punctured, the 

 rest of the surface very sparingly and finely punctate , elytra 

 with the basal portion strongly raised, the shoulders prominent, 

 the surface strongly punctate-striate , the interstices costate at 

 the sides, legs fulvous, jiosterior femora piceous. 



Ilah. Si-Rambé. 



This si)ecies may be known from any of its allies ])y the 

 coloration of the antennae in connection with the black shining 

 upper surface ; it is closely allied to M. })allipes, Jac. l)ut in that 

 species the antennae iiave four intermediate Idack joints and the 

 thorax is impunctate ; I must look upon entirely pale fuh'ous 

 specimens in regard to the antennae and upper surface, as va- 

 rieties, since 1 am unal>le to find any differences in structures, they 

 were also obtained at the same localities and at the same time. 



59. Lactica transversicollis, n. sp. — Bluish-black, the head, 

 the basal joints of the antennae ami the thorax fulvous, the 

 latter with distinct transverse sulcus, microscopically punctured, 

 elytra dark metallic blue, extremely finely and closely punctured 

 in semi- regular rows. 



Length 1 line. 



Head impunctate, the frontal tubercles nearly obsolete, carina 

 short and l)lunt but distinct, palpi slender and pointed, antennae 

 extemling to the base of the elytra, ])lack, the lower four joints 

 fulvous, the second and the following two joints nearly equal, 

 the other joints slightly longer, finely pubescent, thorax trans- 

 verse, twice as broad as long, the sides nearly straigiit, the 

 anterior angles oblique, the surface convex with a distinct slightly 

 sinuate transverse sulcus, bounded laterally by a perpendicular 

 groove , the disc extremely minutely punctured , only visible 

 under a strong lens, scut(dluni small, black, elytra subcylindrical 

 without basal depression, extremely closely punctured in indistinct 

 longitudinal rows , the interstices also very minutely punctate , 

 underside and legs Idackish or th(> latter obscure fulvous at fluì 

 base of 'the fibiae, the first joint of tlie posterior tarsi as long 

 as the second one, prosternum longer than broad, impunctate.
