1286 COLEOPTERA 



basin et ad latera pallide flavis ; thorace impunctato, brevissime 

 flavo-pubescente, disco obtuse trinodoso ; elytris fortiter irregulariter 

 punctatis. 



Long., llmm. 



Antenna slender, not quite reaching extremity of body ; third, 

 fourth, and fifth joints with a few rather long hairs beneath ; the 

 fourth rather shorter than the third or fifth, which are about equal. 

 Eyes convex, but little distant from the thorax. This latter is rather 

 broader than long, with a very large but obtuse prominence on each 

 side of the middle, and between them, just behind the middle, with 

 a smaller prominence : these protuberances are polished and shining, 

 the rest of the surface being covered with a very delicate minute 

 pubescence ; this is of a pallid colour, the thorax itself being of a darker, 

 more vinous red than the rest of the surface. The elytra are pecu- 

 liar, both in form and sculpture ; their basal portion is flattened, but 

 bears a short longitudinal elevation near the suture, and from near 

 the shoulder there extends backwards a fold or plication, which, 011 

 the middle of the length, is very abruptly defined and costiform, and 

 then ceases, there being external to it at the middle of the elytra, 

 close to the side, a shorter abrupt costa ; these costse are pallidly 

 flavescent, the rest of the surface being of a tawny-red colour ; the 

 elytra are evidently narrowed behind, and leave the terminal seg- 

 ment exposed ; the apices not at all spinose ; they have a peculiar 

 rough irregular sculpture, which is not true punctuation, and is not 

 present on the costse ; they have a few short feeble hairs, most dis- 

 tinct at the apex. 



Picton. Helms; one mutilated example of quite uncertain sex. 



Ceralomus. 



Nov. gen. 

 (Sharp ; Trans. Boy. Dub. Soc., 1886, p. 442.) 



Corpus parvum, tomento subtilissime vestitum. Caput exsertum, 

 fronte minus elongate, abrupte perpendiculare ; oculi omnino divisi, 

 supra valde distantes, a thorace remoti. Antenna corpore longi- 

 ores, sat tenues, simplices, articulis 3-6 apicibus subnodosis. Thorax 

 lateribus obtuse angulatis. Coxce anteriores haud proniinulee, 

 parum transversae, acetabulae extus latissime apertae, trochantinis 

 inaximis ; inter se parum distantes. Acetabula intermedia extus 

 late aperta ; metasternum elongatum, episternis modice latis. 



This is another genus, apparently without any ally, to be placed 

 in the New Zealand list near Calliprason, to which, however, it is only 

 very distantly allied ; the facies is rather that of the Lamiidce, such 

 as Hybolasius or Tetrorea sellata, and I had no idea until I investi- 

 gated it that it would prove a Cerambycid, though really its struc- 

 tures are quite normally Cerambycid ; the antennce are inserted on 

 the summit of the depressed head, far from the mandibles ; the eyes 

 are so deeply emarginate that they are practically divided into two 

 parts, of which the superior is much smaller than the inferior ; they 

 are placed far from the front margin of the thorax, and are finely
