larger, but still small and more or less concealed by tlie 

 clothing. 



POROPTERUS ORNATICOLLIS, n. Sp. 



Black : antennae and tarsi more or less red. Sparsely 

 and irregularly clothed with scales varying from ashen to 

 sooty, tubercles with black fascicles, but on prothorax varied 

 with ochreous and whitish scales ; legs rather densely clothed ; 

 a small patch of pale scales near each eye. 



Head with fairly large but sparse and shallow punctures. 

 Eyes with coarser facets than usual. Rostrum moderately 

 long, somewhat dilated to apex; with numerous clearly- 

 defined punctures. Antennae rather thin ; scape inserted two- 

 fifths from apex to rostrum ; second joint of funicle slightly 

 longer than first. Prothorax longer than wide, sides strongly 

 rounded; apex produced and slightly concave, with a con- 

 spicuous fringe about the concave portion ; subapical con- 

 striction deep and abruptly terminated at fringe ; with a 

 median carina, feeble near apex, but appearing at base as a 

 scutellar lobe; with four fasciculated tubercles across middle, 

 and two slightly behind the median ones; with large, round, 

 irregularly-distributed punctures. Elytra narrow and deep, 

 not much wider than widest part of prothorax ; sides with 

 large and usually somewhat angular, distant punctures or 

 foveae, along middle and on posterior declivity much smaller ; 

 third interstice with three distinct but rather small tubercles, 

 the first at about basal fifth, the third near summit of pos- 

 terior declivity, the second halfway between the others ; fifth 

 with three somewhat" smaller tubercles, each placed slightly 

 behind its fellow on the third ; some small shining squami- 

 ferous tubercles on suture and on tubercles. Mesosternal 

 rec€j)tade shorter, but otherwise as in preceding species. 

 Ahdofnen with first and fifth segments each about as long as 

 the otliers combined, suture between first and second deep 

 at sides, but distinct across middle, the other sutures deep 

 and straight. Ler/s long and thin; posterior femora passing 

 apex of elytra; third tarsal joint wide and deeply bilobed. 

 Length, 7h-S mm.

On the prothorax there is a distinct irregular patch of 

 pale scales, commencing at the median fascicles and continued 

 along the carina to the base ; there are also two small medio- 

 apical whitish fascicles, feebly indicated from behind, but 

 very distinct from in front. Many of the elytral punctures 

 have a transverse impression from each side. I cannot satisfy
