Hymenoptera aculeata collected in Algeria. 535 



In form resembling the species with the wider abdominal segments, 

 such as hispanica, rousselii, etc. Head and thorax black clothed with 

 white hairs, mandibles ilavous, antennas black, rather slender, pro- 

 notum with a band on its posterior margin, and a large spot on each 

 side in front yellow, femora black, yellow at the apex, tibise and 

 tarsi pale, the former with a black line on its inner side, wings 

 hyaline, nervures scarcely darker ; abdomen black, the segments 

 scarcely constricted at the base, rather finely and remotely punctured 

 on the disc, more closely on the sides, apical bands pale yellow, 

 narrow, deeply bisinuate, so as to be almost interrupted ; apical 

 segment sharply bidentate ; beneath with a narrow apical band on 

 all the segments, their surfaces very largely and irregularly punc- 

 tured, 6th with its apex truncate ; process of the 8th curved 

 upwards as in the other species. 



Long. 10 m.m. Biskra. F. D. M. 



Myzine, sp. (?). 



£. Four $ <J taken by Mr. Morice at Biskra differ from 

 the $ of Guerinii, which they otherwise resemble in size 

 and form, in having the 3rd joint of the antennae longer 

 than in that species, in having the hairs on the basal joints 

 of the antennae and on the face above the clypeus finer and 

 pale instead of black, the hairs of the thorax paler, and 

 the wings much less infuscate ; as these are doubtless the 

 females of one of the many described males I refrain from 

 giving them a name. 



Tiphia Beckeri, Tourn. 



?. Bone, on Euphorbia helioscopia, 16. iii. 26. 



$. Bone, visiting Diplotaxis or Sinapis nigra, 2. v. 96. 



These specimens agree with Tournier's description in 

 Ann. So. Belg., xxxiii, p. 9, but the species seems to be 

 scarcely distinguishable from morio.
