wedge-shape:!, as long as its peduncle. The 2nd node is almost 

 campaniform, wider behind than in front, wider than the 1st node and 

 slightly longer than wide. 



$ . 8'3 mm. (hitherto undescribed). Eeddish yellow-brown, 

 femora, tibiae, and antennae paler, tarsi brownish yellow. Head dull, 

 the rest of the body shining. Clothed with a moderately abundant, 

 long and yellow pilosity, longer and more abundant on the abdomen 

 than on the head and thorax, much more abundant but shorter on the 

 legs and antennae. Head very closely and strongly punctured, the 

 punctures deep, also partly striate between the punctures. The 

 clypeus shining, sparsely and strongly punctured. The front of the 

 head round the antennal sockets finely and longitudinally striate. 

 Mandibles sharply longitudinally striate, quadridentate. Dorsum of 

 thorax largely but scantily punctured at the sides, leaving a median 

 longitudinal area which is impunctate. Nodes sparsely punctured 

 on their posterior halves, also somewhat rugulose. Abdomen very 

 sparsely and finely punctured. Head as long as wide, subquadrate, 

 the posterior angles strongly rounded, the posterior margin straight. 

 Pronotum hardly exposed above. Mesonotum very convex trans- 

 versely in front, moderately so longitudinally, a little wider than long, 

 and twice as long as the scutellum, which is almost semicircular and 

 not raised much above the level of the epinotum. The dorsum of the 

 epinotum oblique, with a trace of tubercles at the angles, twice as 

 wide at the base as it is long, and not quite as long as the sub- vertical 

 declivity. The junction of the two faces of the epinotum rounded, 

 slightly concave transversely. Nodes as in the $ . Wings long, pale 

 brownish yellow, the nervures dark yellow. 



$ . 3- 3 mm. (hitherto undescribed). Head dark brown, the rest 

 of the body pale brownish yellow, legs and antennae pale yellow. 

 Head very finely and longitudinally striate, sub-opaque ; the rest of 

 the body very smooth and shining, except the anterior angles of the 

 first node, which are feebly striate. A few very fine punctures 

 scattered on the thorax. Pilosity and pubescence as in the $ , but 

 shorter and less abundant. Head much wider in front than behind, 

 almost twice as wide. Eyes very large, occupying a little more than 

 the anterior half of the sides, and almost touching the base of the 

 mandibles in front. The latter finely striate, minutely tridentate, the 

 inner and outer margins parallel. Clypeus with the media u area 

 raised in the form of a tubercle, subtruncate above. Ocelli very large, 

 raised, the posterior pair twice as far apart from each other as they 

 are from the anterior ocellus. Antennae setaceous ; scape very short, 

 barely longer than wide, and not so long as one ocellus. First joint
