other by about the same distance they are from the eyes ; the apex of the clypeus 

 truncate ; the front bearing a distinct furrow ; the apex of the pronotum sharply 

 angled ; the median segment gradually rounded to the apex ; the apex of the penulti- 

 mate ventral segment roundly incised ; the base of the fore tarsi sharply incised and 

 ciliated only ; and the long spur of the hind tibiae reaching quite close to the apex of 

 the metatarsus. 



Cresson describes 1 the wings as fuscous, darker at the tips. The Mexican example 

 has them hyaline, with the tips smoky. 



Here follow four slenderly built species, with black bodies variegated with white, 

 the legs also having more or less white on them ; the wings hyaline, smoky at the 

 apex. (Species 54-57.)

Antennae moderately stout, at the base closely united, the third and fourth joints 

 subequal ; eyes slightly converging at the top ; the hinder ocelli separated from each 

 other by a greater distance than they are from the eyes ; the sides of the clypeus 

 oblique, the apex almost transverse ; there is a furrow on the front above the antennae ; 

 the vertex bears some black hairs ; from the ocelli the face and clypeus are covered 

 with pale golden pubescence. Prothorax as long as the head, the apex angled. 

 Scutellum narrowed towards the apex, which is rounded. Median segment with a 

 rather gradually rounded slope to the apex, where there is a bright yellow elongate 

 mark on either side. Abdomen longer than the head and thorax united, narrowed at 

 the base, somewhat compressed ; the apical ventral segments sparsely covered with 

 longish black hairs ; the penultimate ventral segment roundly incised. Legs longish, 

 densely sericeous ; the spurs, the bases of the middle tibiae, the greater part of the hind 

 tibiae behind, and all the tarsal joints broadly at the base, white ; the fore metatarsus 

 incised at the base ; the tibial spines numerous and minute ; the long spur of the hind 

 tibiae reaching a little beyond the middle of the metatarsus. Wings subhyaline, with 

 the apex smoky ; the basal nervure interstitial ; the anal nervure in the hind wings 

 received beyond the cubital nervure; the second and third cubital cellules subequal. 



J 55. Pompilus dubitatus.

testaceis ; alis hyalinis, apice fumatis. <$ .
