5 . Densely pruinose ; head a little wider than the thorax, 

 clypeus transverse, slightly convex, its anterior margin arched ; 

 median segment broad, with a rounded slope to the apex, where 

 the slope is steep with an inward curve ; legs stout, the tibiae and 

 tarsi with short spines ; abdomen longer than the head and thorax 

 united, pseudosessile and massive. Black, with glittering silvery 

 pile, most dense on the clypeus, the pronotum anteriorly, the 

 median segment, and abdomen, on the last it forms a broad band 

 at the base and a narrow band at the posterior margin of each 

 segment ; wings hyaline with a yellowish tint, the fore wing with 

 a light fuscous cloud occupying the radial, 2nd and 3rd cubital, 

 and upper part of 2nd discoidal cells.

$ . This species is identical in form, sculpture, and markings 

 with P. pedestris, Smith, but I keep it apart, as the 3rd cubital cell 

 is petiolate, not subtriangular as in pedestris. I have also carefully 

 examined the types * of P. vischnu. Cam., in Mr. Eothney's 

 collection, and they as well as the rest of the specimens labelled 

 P. vischnu are, so far as I can make out, nothing more than rather 

 small males of P. incognitus. All have the 3rd cubital cell in the 

 fore wing petiolate f.

" 2 • Head smooth, sessile, flat in front, sulcated round the base 



* Two specimens, both males, are labelled " P. vischnu. Cam., Type" m what 

 I believe is Mr. Cameron's handwriting. 



t Mr. Cameron has made some mistake in his descriptions of Pompilus 

 vivax and Pompilus vischnu. Of the former he says (loc. cii.), " Second cubital 

 cell petiolate," whereas it is the 3rd cubital cell which is petiolate; vide also the 

 Plate figure, which is correct. Of P. vischnu he says, "Identical in colour 

 of the body and wings to P. vivax, differing in the 2ud cubital cell not being 

 petiolate " ! The types and all the specimens labelled P. vischnu in Mr. Eothney's 

 collection hare the 3rd {not 2nd) cubital cell petiolate.
