760 COLEOPTERA 



Euplectus (p- 139)- 



1348. E. tuberigerus, n.s. Shining ; head cand thorax red, 

 elytra and hind-body shghtly infuscate ; legs, antennae, and palpi 

 fulvescent ; pubescent. 



Head convex, vertex bi-foveolate, rather coarsely punctured, 

 the middle least so. Prothorax about as long as broad, rounded 

 laterally ; with a large fovea near each side prolonged forwards, 

 a transversal impression near the base appearing to unite with the 

 former, and a longitudinal cavity on the disc ; its surface is less 

 coarsely sculptured thaii the head, particularly on the dorsum; 

 it bears some short, brassy hairs. Elytra longer and broader than 

 thorax, their sides slightly rounded, each with an entire sutural and 

 abbreviated strios, the latter broad at bas3 but attenuated at the 

 middle : they bear numerous short brassy hairs and seem densely 

 but finely punctulated. Hind-body rather shorter than elytra, the 

 three dorsal segments equal, the others more abruptly deflexed, the 

 third protuberant medially ; clothed like the elytra. Legs stout, 

 tibiae arcuated externally. AntenncB pubescent, stout, as long as 

 head and thorax ; second joint as long as exposed part of the first ; 

 third smaller than second ; joint 4-8 moniliform ; ninth and tenth 

 transverse, much larger than the preceding ones ; eleventh large, 

 ovate, pointed. 



The chief peculiarity of this species consists in the structure of 

 the third abdominal segment ; this is gradually raised towards the 

 middle, thereby assuming the form of an apical protuberance. 



Length, f line ; breadth, nearly -J. 



I found my specimen somewhere near Whangarei Harbour.

Latr. 

 Lacord. ; Hist, des Ins. Col., Tom. 11., p. 205. 



Allied to Silpha, more particularly to SilpJia atrata, but exhibit- 

 ing the following differences : — 



Ligula rather more emarginated. Internal lobe of the onaxillce 

 unarmed or destitute of spines at the extremity. Palpi more 

 filiform. Mandibles simple at apex. Antennce moderate, rather 

 stout ; third joint nearly always longer than the basal one, joints 

 2-6 sub-moniliform, 7-1 1 forming a club, gradually widened and 

 serrate. ProtJiorax transversal, narrowed and emarginated in front, 

 truncate at base. Intermediate coxcz contiguous. The four basal 

 joints of the anterior and intermediate tarsi a little dilated among 

 the males.

V' 47)- 



Niger, nitidus, lasvigatus ; antennarum basi rufescente ; pro- 

 thoracis lateribus late testaceis ; elytris ad apicem attenuatis, ultra 

 abdominis apicem prolongatis, subtiliter striatis, striis in partem 

 prolongatum profundioribus et fortiter punctatis.
