and the dilatation of the elytra behind not so great in 

 proportion to the width of the anterior parts. It differs 

 also in having the prothorax more sparsely punctured, and 

 the anterior transverse groove shallower and less distinct 

 in the middle. 



4. Plaxomicrus oberthuri, sp. n. 



$ . Pale testaceous-yellow, and nitid ; with the elytra in their 

 basal half, excepting a spot on eacli side of the scutellum, violaceous ; 

 the last four or five joints of the antennae, the tarsi, and the outer 

 faces of the tibiae more or less deeply infuscate. Head very minutely 

 punctulate, marked also with some larger sparsely scattered punctures 

 both on the front and vertex. Prothorax slightly nitid, strongly and 

 closely punctured on the centro-notal tubercle and in the transverse 

 groove in front of it ; the centro-notal tubercle slightly flattened 

 on top. Elytra gradually and not strongly dilated behind ; sparsely 

 punctured on the basal violaceous area ; the hind margin of this 

 area indented at the suture and also, but less strongly, at about the 

 middle of the width of each elytron ; setae sparsely scattered above, 

 aggregated at the lateral margins to form a short black fringe. 

 Antennae reaching to the apical third of the elytra. Middle tibia} 

 very feebly curved. Last ventral segment impressed with a median 

 line, flattened and scarcely depressed .in the middle before the apex. 



Long. 12 mm.; lat. ad basin elytrorum, 4 mm.: lat. max. 5*5 mm. 



Sab. Assam, Khasia Hills, 2000'. Type in coll. Oberthilr. 



This species, though having the elytra less dilated 

 posteriorly, and the middle tibiae but very slightly curved, 

 agrees pretty closely in other points of structure with the 

 typical forms of Plaxomicrus, and I have, therefore, placed 

 it in this genus rather than in Gkreonoma towards which 

 it shows an approximation in general form. 



Genus Lasiophrys, gen. nov. 



£ . Head very broad, flattened in front, widest between the lower 

 lobes of the eyes, furnished with a short fringe of hairs just above 

 the upper margin of each of these lobes ; labrum short, broad, 

 attached by an equally short and broad membranous cpistome to the 

 clypeal margin ; mandibles broad, flattened in front. Antennae a 

 little longer than the body; first joint shorter than the third and 

 fringed with short hairs underneath ; last joint somewhat obtusely 

 pointed, and not glabrous, at the apex. Prothorax with a slight 

 protuberance at the middle of each side followed by a groove which 

 extends upwards to, and widens out at, the side of a centro-notal
