tlirougliout, but to the eye appears smooth. Elytra slightly 

 wider near the hind femora than elsewhere ; their sides, 

 however, are only a little rounded ; the shoulders are evidently 

 broader than the base of the thorax, but are not prominent ; 

 their simple strias are well marked throughout, the first and 

 second near the base are confluent, there is a small puncture 

 on each of the third interstices in line with the hind thighs, 

 and the marginal punctures become confused towards the 

 apices. Posterior tihice straight. 



'JMie last ventral segment is much longer than the preceding 

 one; it is obliquely narrowed apically for about half of its 

 length, and, just where the contraction begins, there is a 

 denticle at each side ; there are two setigerous punctures at 

 the apex.

 OoPTERUS, White. 



The following details are characteristic of this genus : — 

 Palpi moderately elongate ; terminal joints thick at the 

 base and very gradually tapering towards the acuminate 

 extremity ; the penultimate quite as long, slender at the base, 

 and dilated towards the apex. Tarsi with the basal two 

 joints dilated, the first oblong, second cordate, both acutely 

 prolonged at the inner angle. Antennce elongate, the basal 

 two joints and the basal portion of the third glabrous. 

 Head with two erect setae near each eye and two on the 

 forehead. Thorax with one lateral seta before the middle 

 and another at each posterior angle. 



Oopterus latipennisy sp. n. 



Shining, piceous ; the antennse, palpi, and legs fusco- 

 testaceous, the margins of the elytra and an ill-defined apical 

 space on each of nearly similar colour. 



Head with large lateral impressions. Eyes not prominent. 

 Antennce elongate, their second joint nearly as long as the 

 following one. Thorax nearly one third broader than long, 

 apex widely but not deeply incurved ; it is widest near the 

 middle and a good deal narrowed behind ; posterior angles
