p. 51. 



Glossy, moderately convex, of inej^ular contoui' ; elytra piceous, with 

 pitchy-red margins ; head and tliorax ruio-pu'eous, legs and basal joints 

 of antennae liglit rutx)-r-astaneous, palpi ])aler. 



Head, and the large moderately convex eyes, a little wider than front 

 of thorax, smooth, with shallow frontal impressions. Thorax subcordate. 

 finely margined, widest and rounded at or just before the middle, gradually 

 narrowed towards the rectangular, slightly prominent hind angles, base 

 and apex siibtruncate, it is about a fourth broader than long ; disc smooth, 

 the well-marked central groove not reaching the apex, basal fossae of 

 moderate size, situated near the angles, with about 4 punctures between 

 them, the lateral plicae obsolete ; the seta at each side, in front of the 

 middle, and the other at the hind angle sometimes missing. Elytra broadh' 

 oval, in the middle double the width and thrice the length of the thorax, 

 yet liardly any broader than it is at the base, with well-developed margins 

 and subapical phcae ; the sutural stria on each usually well marked and 

 punctate, the others more or less obsolete ; interstices plane, the 3rd 

 tripunctate. 



Male. — Anterior tarsi with the basal 2 joints dilated, and prolonged 

 at inner extremity. Antennae reaching backwards to intermediate femora. 



0. fygmeatits (2618) has oblong-oval elytra. 0. parvulus (2617) is 

 rather smaller, and the sides and apices of the elytra are broadly testaceous. 

 In 0. hasalis (3684) the elytra are more oblong, with much more definit(> 

 sculpture, and the whole base of the thorax is pimctate. These are the 

 only near allies.

Mount Dick, near Kingston. A single pair from Mr. T. Hall on the 

 lOth March, 1914. 



3806. Oopterus latifossus sp. nov. 



Nitid, slightly convex ; piceous, elytral margins pitchy-red, their apices 

 fusco-testaceous ; legs and antennae light chestnut-red, the glabrous joints 

 of the latter and the palpi fulvescent ; labrum and mandibles dark rufous- 

 Head rather narrower than thoracic apex, smooth, "ndth elongate inter- 

 ocular impressions ; eyes large but not very convex. Thorax cordiform, 

 a third broader than long, oddest just before the middle, well rounded 

 there, somewhat sinuously narrowed towards the subacute and slightly 

 prominent posterior angles, distinctly marginate, base truncate, apex nearly 

 so ; disc smooth, central groove abbreviated but distinct, basal fossae large 

 and broad, each separated from the side by a plica, the space between 

 them with numerous distinct punctures. Elytra broad, oviform, with well- 

 developed rims, thrice the length but hardly double the width of the rather 

 broad thorax ; their striae moderately deep and distinctly punctate, but 

 becoming obsolete near the individually rounded apices, the outer striae 

 and punctation less obvious ; interstices very slightly convex. 3rd tripunc- 

 tate, apical carinae distinct. 



Male.-^ Anterior tarsi with the 2nd joint little more than half the length 

 of the 1st, both dilated, and slightly prolonged at the inner extremity. 

 Maxillaiy palpi setigeroiis. Thorax with a single seta at each side near 

 the n)iddle. and another at the hind angle.
