Tasch. Of the handsome black, yellow-legged, long-waisted Sceli- 

 phron sjnrifex, L., I took two examples, one at Khartum, the other in 

 the train at Mvit Mir Station on the Sudan Railway; it also occurred 

 at Luxor ; my specimens are all females. PhUanthus coarctahis, Spin., 

 and variegatus, Spin., were both abundant towards Mogran, males greatly 

 predominating. Other abundant small Sphegids were Cerceris albi- 

 cincta, Klug, 28 (J, 2 ?, and C. suhim,pressa, Schlett., 24 i^, 2 ? ; 

 O. annexa, Kohl, was not so common, only 4 J* and 1 ? being- 

 taken. The great majority of these small Sphegids (as well as of 

 Chrysids and Flies), were obtained by sweeping the white fluffy 

 Amarautaceous plant ^rva ?javanica, Juss., but a few were obtained 

 from the Boragineous Arnehia sp. The large bees and wasps on the 

 other hand freqvieuted Tacoma stans. Acacia and Parhinsonia, though 

 a few occurred at Calotrojns. 



Of Bemhex lusca. Spin., I secured one of each sex, of B. medi- 

 ferranea, Handl., three males, one was taken on yErva, one near Burri, 

 where so far as I know that plant did not grow. Of the fine large 

 Sphex timbrosus, Chrst, a black-bodied insect with clear wings, save at 

 the base, a specimen ( (J ) was taken to the west of the town. In the 

 same locality, on a small umbellate weed, I took a male Tachytes, a 

 striking insect with a testaceous abdomen and dark borders to the wings. 

 Mr. Morice thinks this may be the male of swperhiens, Morice, the de- 

 scription of which will shortly appear in the Transactions of the 

 Entomological Society ; he compares it with monetaria, Smith, from 

 India. 



The difficult genus Pompilus was represented by ten males of a 



species of the Ajwrns group. 



No social wasps were met with ; on the other hand the genus 

 Eumenes was much to the fore, by far the commonest species being the 

 Egyptian blue-black E. tinctor, Chrst, of which I took ten males and 

 four females ; of E. dimidiatipennis, Sauss., and E. lepelletieri, Sauss., 

 I took one male each ; of E. esuriens, L., a truly hungry-looking, long- 

 waisted, yellow, brown and black beast, I took one of each sex. Of 

 the large black purple- winged Bhynchium ? syiiagrioides, Sauss., with 

 its orange-tipped tail, I took two of each sex ; it frequented the flowers 

 of Tacoma. Of B. cyanopterum, Saiiss., I found a solitary male at 

 Acacia flowers. Of B. niloticum, Sauss., I took two males at Khartum, 

 another at Atbara junction 200 miles to the northward. A female 

 Odynerus (Jjionotus) belonging to the parvulus group may possibly 

 prove to be a new species. 



The handsome and conspicuous Carpent«r-bees were as common
