In this paper the following 19 species of parasitic Hymenoptera are 

 described, being from Eritrea, except where otherwise stated : — Eury- 

 toma spermophaya, sp. n., taken from berries of an undetermined plant, the 

 seeds of which are attacked by the larvae. Eiiryloma ehngalida, sp. n., 

 and Enqjrtonoius notahiUs, gen. et sp. n., from the same berries. 

 Zeteticonius ahilis, gen. et sp. n., from French Cuinea, parasitising the 

 larvae of Nitidulidae (gen. Carpophilus ?) in fallen fruits. Blastothrix 

 subproxima, sp. n., a parasite of the female of a Pse\idococcus living on 

 Acacia sp. ; Leptomastix superbus, sp. n., and Prochiloneuruspidchellus, 

 gen. et sp. n., parasitic on the female of a Pseiulococcus living on 

 Graminaceae. AetJiognatm afer, gen. et sp. n., from the Gold Coast, 

 taken from adult females of Stictococ/'us diver siseta, Silv. Coccophagus 

 orientaiis, How., var. modesta nov., from Dahomey, taken from adults 

 of Lecunium {Saissetia) nigrum. Coccophagus princeps, sp. n. ; 

 Prococcophagus variiis, gen. et sp. n. ; Physcus semvrmtus, sp. n., a 

 parasite of Chionaspis sp. living on Aloe', Azotus elegantuhis, sp. n., 

 a parasite of females of Chionaspis sp. living on Aloe. Encarsia 

 parvella, sp. n., and Eretmocerus diver sicHialns, sp. n., from Nigeria, 

 parasites of Aleurodidae ; the Coccinellid, Serangitutigiffardii, ({randi, 

 destroys large numbers of E. diver siciliatus, sp. n. Pelorotelopsella 

 nigeriensis, sp. n., from South Nigeria, obtained from a twig covered 

 with Stictococcus sjostedti, Ckll., but whether a primary or secondary 

 parasite is uncertain ; the Sticlococcus was also attacked by the larvae 

 of a Dipteron and by that of the Lepidopteron, Eublemma ochrochroa, 

 Hmpsn., the latter being itself attacked by an Elasmm. Telraslichus 

 stictococci, sp. n., from the Gold Coast, a parasite of the females of 

 Sticlococcus diversiseta, Silv., though whether a primary or secondary 

 parasite is unknown. Tetrastichus giffardianus, sp. n., from South 

 Nigeria and Dahomey, a parasite of Ceratitis giffardii, Bezzi . According 

 to Fullaway, this tetrastichus oviposits in Ceratitis larvae, and it is 

 hoped to acclimatise it in the Hawaiian Islands. Tetrastichus 

 dacicida, sp. n., from Kamerun, a parasite of Dacus bijxirtitus, Graham ; 

 the life-history of this species is probably similar to that of T. giffardii.
