16 THE ENTOMOLOGIST. 



pubescence, Legs normal ; the fore tibia? with a broad yellow band 

 on the apical half. 



This species, from the form of the petiole, is allied to 

 C. ardens and C. odontophorus. The area on the metanotum is 

 not bounded by a furrow; the furrow on its apical slope is wide 

 and deep on the upper half. 



Cerceris flavoplagiata, sp. nov. 

 Black ; the upper part of the head, the mesonotum and scutellum 

 red ; the head and thorax largely marked with yellow, the vertex with 

 four yellow marks in a transverse row ; the abdomen black, the sides 

 of the first segment, the base of the second broadly, its apex and that 

 of the third, fourth, and fifth narrowly, the lines becoming gradually 

 narrower, two marks, wider than long, on the base of the third 

 segment, the edge of the pronotum behind, the middle of the propleura?, 

 a mark behind the tubercles, projecting narrowly upwards at the base,. 

 an irregular mark on the lower part of the mesopleura?, the yellow 

 turning into rufous below and two large oval marks on the apex of the 

 metanotum, extending on to the metapleurae, a mark on the sides of 

 the scutellum and the post-scutellum, yellow. Wings hyaline. ? . 

 Length, 12 mm. 



Hob. Himalayas. 



Antennae rufous, darker above, the scape lined with yellow below. 

 Head : the lower half of the outer orbits, the inner broadly from 

 shortly above the middle, a line extending from the ocelli to the base 

 of the antenna?, dilated below and to a less extent above, the face, 

 clypeus, aud the mandibles, except at the apex, lemon-yellow ; there 

 is a black line commencing shortly behind the ocelli, where it is 

 obliquely narrowed, extending down the sides of the central yellow line 

 to the base of the clypeus. Occiput black below. Clypeus roundly 

 convex, its apex almost transverse, rufous. The outer marks on the 

 vertex are irregularly oval, the two central narrower, longer, and 

 oblique. The whole head is closely and strongly punctured ; the 

 clypeus is less strongly and closely. Thorax punctured, but not 

 strongly, the base of the pronotum shagreened. Metanotal area closely 

 but not very strongly punctured, and more closely on the sides than 

 in the centre. The rnetapleura? at the base above with some stout, 

 clearly separated stria, the lower part and the centre finely, indistinctly 

 striated. Four front legs rufous, mixed with yellow, the coxa? and the 

 femora for the greater part above, black, the middle tarsi black above ; 

 the hinder coxa? black, with a yellow line in the centre above, the 

 trochanters for the greater part yellow, the femora for the greater part 

 black, their tibia? broadly black, as are also the tarsi. Petiole stout, 

 of nearly equal width throughout, fully one-third longer than wide. 

 Pygidium longitudinally rugose, of almost equal width throughout ; 

 the epipygium with the apical two-thirds incised ; the incision becoming 

 gradually, but not much, widened towards the apex. The basal three 

 ventral segments are largely marked with yellow. 



In Bingham's arrangement this species would come in near 

 C. tristis and G. sutphurea.
