Hymcno'ptera actdeata collected in Algeria. 179 



Pbosopis cornuta, Smith. 



^ 4, ^ 2, Le Tarf, on Famicidum vulgare and Ammi 

 visnarja, 25-27, vii, 96. {A. E. E.) 



Peosopis dilatata, Kirb., var. ? 



$ 1. Hippone, on Ammi visnaga, 15, viii, 96. {A. E. E.) 

 This specimen apparently differs only from dilatata in 

 having the yellow colour more developed, it has the 

 mandibles labium and hind tibia3 entirely flavous, and has 

 a small black spot on the intermediate tibiae. The form of 

 the scape of the antenna3, however, and the sculpture 

 throughout appear to me to be identical with those of 

 dilatata. In colour it more resembles ccrvicornis, Costa. 



Prosopis spilota, Forst. 



^ 2 (one stylopized), % 2, Hippone, on Ammi visnaga,

These specimens again are slightly different from what 

 we know here as sjdlota, and I have had very great doubts 

 as to whether I should describe them as a new species or 

 not, but I have decided against doing so. Of the three 

 males one is stylopized so that its characters may have 

 been altered by the effect of the parasite. The others 

 differ from the typical form in having the mandibles and 

 labrum pale. The female differs from the typical form in 

 having the first segment of the abdomen more finely 

 punctured, but the characters are not decided enough to 

 satisfy me that the two forms are distinct. 



Prosopis variegata, F. 



Both sexes common, Constantine, Le Tarf, La Calle, 

 Bone, Hippone, Medea, Biskra, on Ammi visnaga, 

 Eryngiiim triquctrum, trieuspidatum, Thajjsia gar- 

 ganica, May to September. {A. E. E. and F. B. M.) 



All the males in both collections are of the ordinary red- 

 bodied type and nearly all the females have the clypeus 

 with a white central line, but three females of the var.
