250 SJOSTEDTS KILIHANDJARO-HEKU EXPEDITION. 8: 7. 



near the end of the radial cellule, and one of about the same size on the apex of the 

 posterior pair; the nervures black, the 1st abscissa of radius about twice the length of 

 the 2nd; the 1st recurrent nervure is received shortly, but distinctly beyond the middle, 

 the 2nd in the middle; the 1st transverse cubital nervure is roundly curved; the 3rd 

 has the anterior half obliquely bent towards the top of the 2nd. Eyes distinctly con- 

 verging above; the hinder ocelli separated from each other by a distinctly greater distance 

 than they are from the eyes. $ " ' Length 10 mm. 



Meru low lands, Ngare na nyuki. 25th November. 



Head wider than the thorax, the temples narrow, rounded. Prothorax rounded in 

 front; in the middle almost as long as the mesonotum. Metanotum large, more densely 

 pubescent than the mesonotum, the apical slope slightly, broadly depressed in the middle; 

 an indistinct impressed line down the middle of basal half. 3rd antennal joint almost as 

 long as the following 2 united. Tibial spurs long; the anterior metatarsus wilh 3, the 

 2nd joint with 2, and the 3rd with one long spine. 



Poinpilus sericeibalteatus, sp. nov. 



Black, densely covered with a white silky pile, which gives it a whitish appear- 

 ance; on the abdomen the pile forms broad bands; wings hyaline, the apex with a cloud 

 which commences at the end of the radius, the apical abscissa of which turns sharply 

 obliquely upwards, the radial cellule becomes gradually wider from the base to the lower 

 part of the apex, through the nervure sloping sharply, obliquely; the 2nd abscissa of the 

 radius is about 4 times longer than the 3rd; the 2nd cellule is large, the 3rd small; the 

 1st recurrent nervure is received shortly but distinctly before the middle, the 2nd in the 

 middle of the cellule; transverse median nervure interstitial; the accessory nervure in 

 hind wings received before the cubitus. Anterior spurs white, the 4 posterior black ; fore 

 metatarsus incised at the base, the long spur of the hind tibiee extends shortly beyond 

 the middle. Temples short. Hinder ocelli separated from the eyes by almost the same 

 distance as they are from each other, o 71 . - - Length 6 mm. 



A slender species. The base of the mesonotum is rounded. 3rd joint of antenna? 

 a very little shorter than the 4th. Palpi black, covered with white pile. Tips of 

 mandibles rufo-testaceous. 



Pompilus exploratrix, sp. nov. 



Black, covered with a white pile; the wings fuscous, darker towards the apex, the 

 nervures black; the apex of the wings darker coloured; the 2nd abscissa of radius about 

 4 times longer than the 3rd; the apical abscissa of radius straight, oblique, extending 

 clearly beyond the cubital cellules; the 1st recurrent nervure received shortly, the 2nd 

 at a greater distance beyond the middle; the transverse median nervure shortly beyond 

 the transverse basal; the accessory nervure in hind wings before the cubitus. Ocelli in 

 a curve, the hinder separated from each other by double the distance they are from the 

 eyes. Front with a narrow, but distinct furrow. Temples almost obsolete, the occiput
