POMPILUS. 



153 



legs with stout scattered spines, the anterior tibiae and tarsi feebly 

 ciliated on the outer side; claws bitid ; abdomen longer than the 

 head and thorax, subcylindrical. Black, the wings hyaline, with a 

 broad fuscous apical margin to the anterior pair ; a narrow line 

 round the orbits of the eyes interrupted on the vertex, the posterior 

 margin of the pronotum, a spot on the mesonotum, another on the 

 side of the thorax close to the base of the fore wing, a third at the 

 base of the posterior tibiae, with a large irregular mark on each 

 side of the base of the 2nd and 3rd abdominal segments, and a 

 fascia at the apex of the 5th segment, yellowish white ; the pro- 

 notum and median segment are adorned with pale pubescent pile, 

 and the front below the antennae \\dth silvery pile.

$ . Pruinose ; head broader than the thorax ; clypeus subconvex, 

 its anterior margin slightly arched, almost transverse in the 

 middle, oblique at the sides ; pronotum with a wide arch posteriorly ; 

 scutellum prominent ; the median segment gradually sloped to the 

 apex, where it is slightly depressed in the middle ; abdomen 

 pseudosessile ; legs with the tibiae and tarsi spinose, the spines 

 stout, the inner calcaria of the intermediate and posterior tibite 

 nearly as long as the metatarsus. Black; a line on the anterior 

 margin of the clypeus joining two lateral spots on it, the orbits 

 of the eyes except at the top, the scape of the antennae in front, 

 the posterior margin of the pronotum, a minute spot on the 

 tegulae, and trans\erse fasciae at the base of the 2nd, 3rd, and 5th 

 abdominal segments, yellow ; the fascia on the 2nd segment is 

 interrupted in the middle, that on the 5th is posteriorly emarginate ; 

 the flagellum of the antennae below, and the intermediate and 

 posterior femora and tibiae, red ; wings hyaline, broadly infuscated 

 at apex. 



The markings are very variable in this species — the clypeus 

 may be without the submarginal line, the yellow may extend up 

 the face to the base of the antennae, the mesonotum at apex and 

 the scutellum may be marked with yellow, the femora and tibiae 

 of the anterior as well as of the other legs may be red, and some- 

 times the yellow fasciae on the abdomen except on the 2nd segment 

 are entirely wanting.
