 Anthophila. 



Plesiopanurgus, gen. nov. 

 Radial cellule reaching to the base of the apical third of the space between 

 the stigma and apes ; apes of radius oblique, rounded. Stigma not much 

 thicker than the costal nervure, sharply pointed at the apex. 1st abscissa of 

 cubitus nearly as long as the 2nd ; the recurrent nervures distant from the 

 transverse cubitals. Trophi long — longer than the head and thorax united ; 

 labial palpi 4-jointed ; the 1st joint not quite so long as the 2nd ; the 3rd 

 distinctly shorter than the 1st ; the 4th minute ; ocelli in a curve, the middle 

 placed very shortly in front of lateral. Eyes large, reaching to base of man- 

 dibles. Labrum large, broadly depressed in the centre, the apex raised. 

 Mandibles long, edentate ; calcaria and claws simple. Pubescence dense, much 

 denser and longer in the <£ than in the $ ; the abdomen in the latter without 

 distinct hair fringes above, the apical segments densely covered with long hair ; 

 the pygidium bare, triangular. The pubescence on the $ is much longer and 

 denser all over than it is in the 9, but more especially on the legs and abdo- 

 men ; it is also larger, more stoutly built, the head also being larger and 

 wider ; structurally it differs in the sides of the pronotum forming a large, 

 oblique projection, narrow at the top, becoming widened gradually below. 

 The antennae are very different structurally in the $ from what they are in 

 the $ ; the scape is much stouter, swollen, of almost equal width throughout^ 

 about 3 times longer than thick ; the last joint is longish, broad at the base, 

 becoming abruptly narrowed on the apical half, into a narrowed, cylindrical, 

 slightly curved projection ; the scape is almost double the thickness of the 

 flagellum. The penultimate ventral segment at apex is raised semicircularly in 

 the middle at the base. The sides of the metanotum in the $ form a broad 

 semicircular projection ; the 9 h;is them rounded gradually from the top to 

 the bottom. If the sexes of the species here described are correctly united, 

 then the $ is much larger, stouter and has a much larger and wider head than 

 the 9 , the head in the latter not being wider than the thorax. The eyes in 

 the $ are more distinctly narrowed above than they are in the 9 . 



This genus belongs to the Panwgido', a group new to the Indian Fauna. 

 The $ may be easily known by the peculiar form of the antennas and of the 

 prothorax. In the tables of Ashmead the genus comes close to Panurgus 

 (Trans. Am. Ent. Soc. XXV., p. 85) which has the 1st joint of the labial
