EcTATOCrBA TERRUCOSA, sp. n. (PI. XXXIX. fig. 2.) 

 S . E. tuberosm Est. similis, sed rostro iu dorso creberrime punctato ; prothorace ad apicem magis 

 constricto, setulis minutis iiigris obslto ; elytris non squamosis, serie tuberculorum prima e 

 taberculis duobus maximis et uno parvo basali composita, tuberculo sublmmerali et prseapicali 

 omnino deficientibus ; femoribus posticis elytra evidenter superantibus ; segmento primo 

 ventrali maris in medio elevate et valde bituberculato. 



Colour uniform dull black, the legs and the apices of the tubercles on the elytra 

 shiny. 



Head impunctate on the vertex, the forehead sparsely punctate and with a deep 

 central fovea, a small tubercular elevation above each eye. Bostrum closely and finely 

 punctate above, the punctures coarser laterally towards the base ; a faintly elevated 

 narrow impunctate central line, which merges near the apex into a broad median 

 impression. Antennae with joint 2 of the funicle scarcely longer than 1, joints 4 to 7 

 short and approximately equal, 3 a little longer. Prothorax subconical, as long as the 

 basal width, broadest at the base, gradually narrowing anteriorly (the sides almost 

 straight in the basal half) and suddenly constricted at the apex, the basal margin 

 shallowly bisinuate ; the upper surface only slightly convex, with scattered shallow 

 punctures, leaving a narrow smooth central line which is faintly impressed in the 

 middle, the punctures much closer along the basal margin ; there are no scales in the 

 posterior angles, and each puncture bears a minute recumbent dark seta. Elytra a 

 little longer than broad, the basal margin distinctly sinuate on each side, the external 

 angles produced forwards, the apex subtruncate and with a small tubercular prominence 

 on each side, the sides strongly rounded, the greatest breadth before the middle, the 

 dorsal outline very convex, the coarsely punctate striae comparatively regular and 

 disappearing before the apex ; interval 3 * with three tubercles, the first very small 

 and close to the base, the other two large and obtusely conical, one being just in front 



* Equivalent to Eaust's " Spatium 2."
